79th Sustainment Support Command Los Alamitos by Los Angeles District USACE

Joint Forces Training Base home to energy-efficient headquarters

LOS ALAMITOS, Calif. -- Soldiers, family members and civilians of the 79th Sustainment Support Command will soon have a new headquarters, organizational maintenance area and acres of parking at the Joint Forces Training Base here. The work is all part of a nearly $25 million project managed by the U.S. Army Corps of Engineers Los Angeles District.

Andy Stevens of Retrofit Services Company from Rancho Cucamonga, Calif., was onsite Sept. 12 putting the finishing touches on the computerized building management system that will control the state-of-the-art energy efficient heating, ventilation, and air conditioning for the headquarters building. The system uses multiple condensers and is nearly 30 percent more efficient than systems of just five years ago.

"This one [building zone] is calling for one stage cool, fans on, temperature is 72 [degrees] in the zone and the set point is 72, so it's doing just fine," said Stevens. "You can change your occupancy status at any time, emergency override it, shut it down and we do have the chemical alert push-buttons that will close all dampers inside and out."

The alert buttons are located throughout the facility and once activated because of an attack or a release of hazardous chemicals, no air is allowed in or out of the building to protect the occupants, according to Maj. Phillip Oster, the U.S. Army Corps of Engineers Los Angeles District's Santa Ana Resident Office deputy who oversees the project.

To reduce construction costs and increase future savings, the project is using eco-friendly features, like re-cycled material, and in the case of the covered parking lots, they will generate energy with a photovoltaic system. The contract partner's quality assurance manager for the project explained the feature.

"At peak, they produce 375 KVA [kilovolt-amps]," said Edward Desmond, Cox Construction of Vista, Calif. "In theory, it's enough power to offset the footprint of the Army Reserve Center building."

While not designated a net-zero facility, the extensive use of energy efficient materials during construction will enable the photovoltaic system to actually return power to the Los Alamitos grid, off-setting the operating costs of other buildings on the base, according to Desmond.

The Energy Policy Act of 1992 mandated the use of "low flush" urinals in government facilities. This project takes it a step further with water-free urinals. The USACE Engineer Research and Development Center estimates that they pay for themselves in six-months to three years and the cost savings don't end there. All new Army construction is designed to satisfy the Silver-level standards of the Leadership in Energy and Environmental Design rating system, in accordance with the U.S. Green Building Council guidance.

According Oster, the project is in the "punch list" stage with safety officials, contractors and District project delivery teams making final inspections before furniture is installed and the customer takes possession of the ARC in October.

About Freedom Golf Association

Freedom Golf Association (FGA), a 501(C)3 non-profit charitable organization, is the leading adaptive golf organization in Illinois and is a charter member of the United States Adaptive Golf Alliance. FGA was founded in July 2012 by Edmund (E.Q.) Sylvester. E.Q. is a director of the Western Golf Association (WGA), member of the United States Senior Golf Association (USSGA), member of the United States Golf Association (USGA) and a triple amputee. FGA is dedicated to bringing joy and a sense of freedom to the special needs community through their inclusion in the game of golf.

FGA believes that all special needs individuals deserve a chance to accomplish the same things as any others do and work towards bringing a positive transformation to their lives. FGA contributes to the positive development of those with special needs through the magic of golf.

FGA works to assist individuals with disabilities in many ways:

•Provides professionally run adaptive golf instructional clinics and golf events

•Engages children, adults and veterans with special needs in FREE adaptive golf instruction with other classmates

•Conducts adaptive golf training workshops to increase the number of qualified adaptive golf coaches to instruct individuals with special needs

•Provides leadership and collaboration with nationally recognized organizations on how to expand/grow adaptive golf programs

Based on its growing understanding of the needs of disabled golfers, the FGA has developed a ground-breaking Adaptive Golf Enhancement Program™ that increases the golfing ability of special needs golfers. FGA’s golf coaches learn this six-step process, which helps them better understand and enhance the capabilities of special needs golfers.

To assist coaches and special needs golfers in determining what adaptive measures would be most beneficial, FGA recently invested in what they call a “personal swing sensors and computerized program” to 1) measure the disabled golfer’s initial swing path and limitations; 2) develop an appropriate exercise program to improve flexibility and range of motion; and 3) to chart the golfer’s progress, using the initial swing measurements as a baseline.

In 2016, FGA provided more than 1,300 adaptive golf lessons. In the same year, 110 special needs golfers went out and played on the course. Ten individuals became trained FGA Adaptive Golf Coaches, growing the total number to 42.

79 cents out of every dollar received goes to FGA’s special needs golf programs and events. FGA has led 40 Chicagoland courses in becoming accessible to the disabled community.

Humphreys hosts Army 10-miler shadow run

By W. Wayne Marlow, U.S. Army Garrison Humphreys, Public Affairs

CAMP HUMPHREYS, SOUTH KOREA – Over 300 runners from across the Korean peninsula took part in the second annual Army 10-miler Shadow Run hosted here Oct. 2.

First Lieutenant Robert Anderson of the 532nd Military Intelligence Battalion won the nighttime race, designed to mirror the Army’s annual run in Washington, D.C., in 1 hour, 3 minutes and 51 seconds. First Lieutenant Sarah Rainville took the women’s crown, finishing in 1:16:44.

Anderson said he initially thought only about doing his best and having a good run. But when some entrants passed him early in the race, his focused changed.

“I was going to try and take it easy ... but then an adrenaline rush hit and I decided to pick it up,” he said.

Anderson maintained a steady pace, running the second half in just two more minutes than he did the first five miles. “I felt good the whole time,” he said. “I felt like I had some left in the tank. I started training for it last year, so I’ve been upping my mileage.”

The Camp Humphreys shadow run will be shown on a large screen during the Army 10-miler in Washington, D.C., on Oct. 9, and Anderson plans to be there to watch it and participate in his second 10-miler of the week. “This was prep for that one,” he said.

Former United States Army Garrison Humphreys Command Sgt. Maj. Jason Kim fired the opening gun at 9 p.m. locally to coincide with the actual time the run will start in Washington D.C. Led by Kim’s replacement, Command Sgt. Maj. Spencer Gray, the runners started under the Super Gym walkway, then snaked their way around the airfield twice, ending up back at Super Gym.

“It’s an absolutely great event,” Gray said. “Soldiers work hard, so when you can do something like this to build esprit de corps, it’s a positive thing. It’s an opportunity for everyone to have a good time.”

The crisp, cool October air helped keep the runners fresh, as did rehydration stations manned by volunteers along the route. The constant encouragement by fellow runners and cheering from the sidelines helped push the runners toward the finish.

“It’s not too cold. It’s nice running weather,” Gray said. “You can always wear something to keep you warm, and if it gets too hot, you can dress down.”

Anderson agreed that the race featured ideal conditions. “It’s great weather, no overheating,” he said. “It’s the best weather for running.”

Anderson said he has three brothers in the Army who are also all enthusiastic runners, and there was another family connection of note. Specialist Charles Rodgers IV flew from Hawaii to run the race with his father, Charles Rodgers III, who manages Splish and Splash Water Park on Humphreys. The two finished with identical times of 1:32:40.

Besides ideal weather and enthusiastic observers, the runners were treated to replicas of Washington, D.C., monuments built by Jeffrey Hubbard of the USAG Humphreys Family, Morale Welfare and Recreation office. The replicas, made of Styrofoam and braced by wood supports, included the Vietnam Memorial, the Pentagon, the Washington Monument, the Lincoln and Jefferson memorials, and the capitol. The project took about two weeks, according to Hubbard.

“It was to give everybody something extra to look at during the run and to do something different,” Hubbard said. “We figured looking at a poster would be kind of boring. We wanted to give them incentive to go and see the next one. They’ll be here next year. They’re built to last.”

Area III Sports Director Lonnie Herring credited volunteers with helping make the run a success.

“We had three drink tables on the trail and at the start and finish point,” he said. “We had BOSS bring in volunteers, folks standing on the road, and people handing out numbers and pace chips before the race.” The computerized chips, attached to the runners’ shoes, started and stopped when someone crossed the start and finish lines, giving everyone an accurate 10-mile time.

For all the logistics involved in having hundreds of people run 10 miles, Herring said most of the work was done beforehand.

“The pre-registration is the most time-consuming,” he said, also mentioning coordination with Military Police, road closures, medical considerations, and taxi and bus services being suspended. But all the work paid off in the end, Herring noted.

Prior to the run, entrants were addressed by USAG Humphreys Commander, Col. Joseph P. Moore.

“We’re here to have fun, and I hope your commanders told you that if you run this, there’s no P.T. tomorrow. Ten miles is no small task,” Moore said. “I’ve run this loop a lot at night. There’s plenty of light out there. The terrain is real friendly. There are no big hills, just a lot of open room to run.”

The top three finishers in the men’s 29 and under category were: Wbatt Reith (1:07:53); Samuel Smiths (1:09:09) and Daniel Bates (1:09:35). Following Anderson in the men’s 30-39 category were David Snow (1:12:41) and Nathan Stahl (1:18:02).

In the men’s 40-49 category, the top three finishers were Brett Bassett (1:14:49), Dan Burnett (1:17:06) and Felix Lassus (1:18:57). Leading the way in the men’s 50 and over category were Robert Nott (1:09:14), Mark Sullivan (1:09:57) and Kwon, Song-ki (1:19:23).

Following Rainville in the women’s 29 and under category were Kyle Wilson (1:22:20) and Liela Moser (1:26:01). In the women’s 30 and over category, top finishers were Sarah Stahl (1:20:45), Adam Leinen (1:27:52), and Jamila Moody (1:34:11). Taking the women’s over 40 crown was Kim, Hui-ok (1:37:06). In the women’s over 50 category, Barbara Garner (1:37:31) took first, followed by Susan Jentoft (1:43:23).

Times Square NYC New Years Eve Midnight Ball Drop - New Years Day Celebration New York City USA 2020 - 2021

The Times Square Ball is a time ball located atop the One Times Square building in New York City, primarily utilized as part of New Year's Eve celebrations held in Times Square. Yearly at 11:59 p.m. EST on December 31, the ball is lowered 77 feet (23 m) down a specially designed flagpole, resting on the midnight to signal the start of the new year. The first ball drop in Times Square took place on December 31, 1907, and has been held annually since (except in 1942 and 1943 in observance of wartime blackouts). The ball's design has also been updated over the years to reflect new advances in technologies—its original design utilized 100 incandescent light bulbs, iron, and wood in its construction, while its current incarnation features a computerized LED lighting system and an outer surface consisting of triangle-shaped crystal panels. As of 2009, the ball is also displayed atop One Times Square year-round and is removed only for general maintenance.

The Ball is covered with a total of 2,688 Waterford Crystal triangles

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC (New General Catalogue) 598. With the D25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years), the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way. It is one of the most distant permanent objects that can be viewed with the naked eye.[7]

The galaxy is the smallest spiral galaxy in the Local Group (although the smaller Large and Small Magellanic Clouds may have been spirals before their encounters with the Milky Way), and is believed to be a satellite of the Andromeda Galaxy or on its rebound into the latter due to their interactions, velocities,[8] and proximity to one another in the night sky. It also has an H II nucleus.[9]

Etymology

The galaxy gets its name from the constellation Triangulum, where it can be spotted.

It is sometimes informally referred to as the "Pinwheel Galaxy" by some astronomy references,[10] in some computerized telescope software, and in some public outreach websites.[11] However, the SIMBAD Astronomical Database, a professional database, collates formal designations for astronomical objects and indicates that Pinwheel Galaxy refers to Messier 101,[12] which several amateur astronomy resources including public outreach websites identify by that name, and that is within the bounds of Ursa Major.[13][14]

Visibility

Under exceptionally good viewing conditions with no light pollution, the Triangulum Galaxy can be seen with the 20/20 vision naked eye;[15] to those viewers, it will sometimes be the farthest permanent entity visible without magnification.[16][17] Its light diffuses (spreads) across a little more than a pinprick of the unmagnified sky, the cause of which is its broadness – this astronomers term a diffuse, rather than compact, object.

Observers range from finding the galaxy easily visible by direct vision in a truly dark (and impliedly dry, cloud-free) sky to needing to use averted vision in rural or suburban skies with good viewing conditions.[15] It has been chosen as one of the critical sky marks of the Bortle Dark-Sky Scale,[18] supported by its relative invariability, reasonable northern declination, and brightness described.

Observation history

The Triangulum Galaxy was probably discovered by the Italian astronomer Giovanni Battista Hodierna before 1654. In his work De systemate orbis cometici; deque admirandis coeli caracteribus ("About the systematics of the cometary orbit, and about the admirable objects of the sky"), he listed it as a cloud-like nebulosity or obscuration and gave the cryptic description, "near the Triangle hinc inde". This is in reference to the constellation Triangulum as a pair of triangles. The magnitude of the object matches M33, so it is most likely a reference to the Triangulum Galaxy.[19]

The galaxy was independently discovered by Charles Messier on the night of August 25–26, 1764. It was published in his Catalog of Nebulae and Star Clusters (1771) as object number 33; hence the name M33.[20] William Herschel compiled his extensive catalog of nebulae, he was careful not to include most of the objects identified by Messier.[21] However, M33 was an exception, and he cataloged this object on September 11, 1784, as H V-17.[22]

Herschel also cataloged the Triangulum Galaxy's brightest and largest H II region (diffuse emission nebula containing ionized hydrogen) as H III.150 separately from the galaxy itself; the nebula eventually obtained NGC number 604. As seen from Earth, NGC 604 is located northeast of the galaxy's central core. It is one of the largest H II regions known, with a diameter of nearly 1500 light-years and a spectrum similar to that of the Orion Nebula. Herschel also noted three other smaller H II regions (NGC 588, 592, and 595).

It was among the first "spiral nebulae" identified as such by Lord Rosse in 1850. In 1922–23, John Charles Duncan and Max Wolf discovered variable stars in the nebulae. Edwin Hubble showed in 1926 that 35 of these stars were classical Cepheids, thereby allowing him to estimate their distances. The results were consistent with the concept of spiral nebulae being independent galactic systems of gas and dust, rather than just nebulae in the Milky Way.[23]

Properties

The Triangulum Galaxy is the third largest member of the Local Group of galaxies. It has a diameter measured through the D25 standard - the isophote where the surface brightness of the galaxy reaches 25 mag/arcsec2, to be about 18.74 kiloparsecs (61,100 light-years),[5] making it roughly 60% the size of the Milky Way. It may be a gravitationally bound companion of the Andromeda Galaxy. Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion stars for Andromeda Galaxy.[6]

The disk of Triangulum has an estimated mass of (3–6) × 109 solar masses, while the gas component is about 3.2 × 109 solar masses. Thus, the combined mass of all baryonic matter in the galaxy may be 1010 solar masses. The contribution of the dark matter component out to a radius of 55×103 ly (17 kpc) is equivalent to about 5 × 1010 solar masses.[4]

Location – distance – motion

Estimates of the distance from the Milky Way to the Triangulum Galaxy range from 2,380×103 to 3,070×103 ly (730 to 940 kpc) (or 2.38 to 3.07 Mly), with most estimates since the year 2000 lying in the middle portion of this range,[25][26] making it slightly more distant than the Andromeda Galaxy (at 2,540,000 light-years). At least three techniques have been used to measure distances to M 33. Using the Cepheid variable method, an estimate of 2,770×103 ± 130×103 ly (849 ± 40 kpc) was achieved in 2004.[27][28] In the same year, the tip of the red-giant branch (TRGB) method was used to derive a distance estimate of 2,590×103 ± 80×103 ly (794 ± 25 kpc).[29] The Triangulum Galaxy is around 750,000 light years from the Andromeda Galaxy.[30]

In 2006, a group of astronomers announced the discovery of an eclipsing binary star in the Triangulum Galaxy. By studying the eclipses of the stars, astronomers were able to measure their sizes. Knowing the sizes and temperatures of the stars, they were able to measure the absolute magnitude of the stars. When the visual and absolute magnitudes are known, the distance to the star can be measured. The stars lie at the distance of 3,070×103 ± 240×103 ly (941 ± 74 kpc).[25] The average of 102 distance estimates published since 1987 gives a distance modulus of 24.69, or .883 Mpc (2,878,000 light-years).[31]

The Triangulum Galaxy is a source of H2O maser emission.[32] In 2005, using observations of two water masers on opposite sides of Triangulum via the VLBA, researchers were, for the first time, able to estimate the angular rotation and proper motion of Triangulum. A velocity of 190 ± 60 km/s relative to the Milky Way was computed, which means Triangulum is moving towards Andromeda Galaxy and suggesting it may be a satellite of the larger galaxy (depending on their relative distances and margins of error).[8]

In 2004, evidence was announced of a clumpy stream of hydrogen gas linking the Andromeda Galaxy with Triangulum, suggesting that the two may have tidally interacted in the past. This discovery was confirmed in 2011.[33] A distance of less than 300 kiloparsecs between the two supports this hypothesis.[34]

The Pisces Dwarf (LGS 3), one of the small Local Group member galaxies, is located 2,022×103 ly (620 kpc) from the Sun. It is 20° from the Andromeda Galaxy and 11° from Triangulum. As LGS 3 lies at a distance of 913×103 ly (280 kpc) from both galaxies, it could be a satellite galaxy of either Andromeda or Triangulum. LGS 3 has a core radius of 483 ly (148 pc) and 2.6 × 107 solar masses.[35]

Pisces VII/Triangulum (Tri) III may be another satellite of Triangulum.[36]

Structure

In the French astronomer Gérard de Vaucouleurs' revised Hubble Sandage (VRHS) system of galaxy morphological classification, the Triangulum Galaxy is classified as type SA(s)cd. The S prefix indicates that it is a disk-shaped galaxy with prominent arms of gas and dust that spiral out from the nucleus—what is commonly known as a spiral galaxy. The A is assigned when the galactic nucleus lacks a bar-shaped structure, in contrast to SB class barred spiral galaxies. American astronomer Allan Sandage's "(s)" notation is used when the spiral arms emerge directly from the nucleus or central bar, rather than from an inner ring as with an (r)-type galaxy. Finally, the cd suffix represents a stage along the spiral sequence that describes the openness of the arms. A rating of cd indicates relatively loosely wound arms.[37]

This galaxy has an inclination of 54° to the line of sight from Earth, allowing the structure to be examined without significant obstruction by gas and dust.[38][39] The disk of the Triangulum Galaxy appears warped out to a radius of about 8 kpc. There may be a halo surrounding the galaxy, but there is no bulge at the nucleus.[40] This is an isolated galaxy and there are no indications of recent mergers or interactions with other galaxies,[39] and it lacks the dwarf spheroidals or tidal tails associated with the Milky Way.[41]

Triangulum is classified as unbarred, but an analysis of the galaxy's shape shows what may be a weak bar-like structure about the galactic nucleus. The radial extent of this structure is about 0.8 kpc.[42]

The nucleus of this galaxy is an H II region,[32] and it contains an ultraluminous X-ray source with an emission of 1.2 × 1039 erg s−1, which is the most luminous source of X-rays in the Local Group of galaxies. This source is modulated by 20% over a 106-day cycle.[43] However, the nucleus does not appear to contain a supermassive black hole, as an upper limit of 3,000 solar masses is placed on the mass of a central black hole based upon the velocity of stars in the core region.[44]

The inner part of the galaxy has two luminous spiral arms, along with multiple spurs that connect the inner to the outer spiral features.[38][39] The main arms are designated IN (north) and IS (south).[45]

Star formation

In the central 4′ region of this galaxy, atomic gas is being efficiently converted to molecular gas, resulting in a strong spectral emission of CO. This effect occurs as giant molecular clouds condense out of the surrounding interstellar medium. A similar process is taking place outside the central 4′, but at a less efficient pace. About 10% of the gas content in this galaxy is in the molecular form.[38][39]

Star formation is taking place at a rate that is strongly correlated with local gas density, and the rate per unit area is higher than in the neighboring Andromeda Galaxy. (The rate of star formation is about 3.4 Gyr−1 pc−2 in the Triangulum Galaxy, compared to 0.74 in Andromeda.[46]) The total integrated rate of star formation in the Triangulum Galaxy is about 0.45 ± 0.1 solar masses per year. It is uncertain whether this net rate is currently decreasing or remaining constant.[38][39]

Based on analysis of the chemical composition of this galaxy, it appears to be divided into two distinct components with differing histories. The inner disk within a radius of 30×103 ly (9 kpc) has a typical composition gradient that decreases linearly from the core. Beyond this radius, out to about 82×103 ly (25 kpc), the gradient is much flatter. This suggests a different star formation history between the inner disk and the outer disk and halo, and may be explained by a scenario of "inside-out" galaxy formation.[40] This occurs when gas is accumulated at large radii later in a galaxy's life space, while the gas at the core becomes exhausted. The result is a decrease in the average age of stars with increasing radius from the galaxy core.[47]

Discrete features

Using infrared observations from the Spitzer Space Telescope, a total of 515 discrete candidate sources of 24 μm emission within the Triangulum Galaxy have been catalogued as of 2007. The brightest sources lie within the central region of the galaxy and along the spiral arms.

Many of the emission sources are associated with H II regions of star formation.[48] The four brightest HII regions are designated NGC 588, NGC 592, NGC 595, and NGC 604. These regions are associated with molecular clouds containing (1.2–4) × 105 solar masses. The brightest of these regions, NGC 604, may have undergone a discrete outburst of star formation about three million years ago.[49] This nebula is the second most luminous HII region within the Local Group of galaxies, at (4.5 ± 1.5) × 107 times the luminosity of the Sun.[46] Other prominent HII regions in Triangulum include IC 132, IC 133, and IK 53.[45]

The northern main spiral arm contains four large HII regions, while the southern arm has greater concentrations of young, hot stars.[45] The estimated rate of supernova explosions in the Triangulum Galaxy is 0.06 Type Ia and 0.62 Type Ib/Type II per century. This is equivalent to a supernova explosion every 147 years, on average.[50] As of 2008, a total of 100 supernova remnants have been identified in the Triangulum Galaxy,[51] the majority of which lies in the southern half of the spiral galaxy. Similar asymmetries exist for H I and H II regions, plus highly luminous concentrations of massive, O type stars. The center of the distribution of these features is offset about two arc minutes to the southwest.[45] M33 being a local galaxy, the Central Bureau for Astronomical Telegrams (CBAT) tracks novae in it along with M31 and M81.[52]

About 54 globular clusters have been identified in this galaxy, but the actual number may be 122 or more.[41] The confirmed clusters may be several billion years younger than globular clusters in the Milky Way, and cluster formation appears to have increased during the past 100 million years. This increase is correlated with an inflow of gas into the center of the galaxy. The ultraviolet emission of massive stars in this galaxy matches the level of similar stars in the Large Magellanic Cloud.[53]

In 2007, a black hole about 15.7 times the mass of the Sun was detected in this galaxy using data from the Chandra X-ray Observatory. The black hole, named M33 X-7, orbits a companion star which it eclipses every 3.5 days. It is the largest stellar mass black hole known.[54][55]

Unlike the Milky Way and Andromeda galaxies, the Triangulum Galaxy does not appear to have a supermassive black hole at its center. This may be because the mass of a galaxy's central supermassive black hole correlates with the size of the galaxy's central bulge, and unlike the Milky Way and Andromeda, the Triangulum Galaxy is a pure disk galaxy with no bulge.[56]

Relationship with the Andromeda Galaxy

Triangulum on the collision paths of the Milky Way and Andromeda galaxies.

As mentioned above, M33 is linked to M31 by several streams of neutral hydrogen[57] and stars,[57] which suggests that a past interaction between these two galaxies took place from 2 to 8 billion years ago,[58][59] and a more violent encounter will occur 2.5 billion years in the future.[57]

The fate of M33 was uncertain in 2009 beyond seeming to be linked to its larger neighbor M31. Suggested scenarios include being torn apart and absorbed by the greater companion, fueling the latter with hydrogen to form new stars; eventually exhausting all of its gas, and thus the ability to form new stars;[60] or participating in the collision between the Milky Way and M31, likely ending up orbiting the merger product and fusing with it much later. Two other possibilities are a collision with the Milky Way before the Andromeda Galaxy arrives or an ejection out of the Local Group.[61] Astrometric data from Gaia appears in 2019 to rule out the possibility that M33 and M31 are in orbit. If correct, M33 is on its first infall proper into the Andromeda Galaxy (M31).[62]

Planetary nebulae

Planetary nebulae are not only important contributors to the chemical enrichment of galaxies, but provide valuable information on single and binary stellar evolution. In addition, these objects seem to always produce very bright planetary nebulae with consistent luminosities, regardless of the galaxy's mass, age, or metallicity. This feature is very useful as a standard candle for distance measurements.

Large systematic research on this topic has been done by Rebeca Galera-Rosillo and co-authors in 2018.[63] This work benefited from the use of the INT and WHT telescopes located at La Palma island. As a result of this study, three new planetary nebulae were discovered.

Newly discovered PNe (2018), Rebeca named the PNe after her closest family members.

Part of the new health care system to come will be to computerize all health care records. The "V-Chip" is a microChip which would be embedded in the arm of patients. Health care professionals would then scan the arm, and retrieve an ID number, allowing them to access personal information. 515 hospitals have agreed to take part in the VeriChip system. 100 hospitals are already trained and set up to use the VeriChip so far. This is just the first step. Combined with the National ID, (complete with rfid chips) Americans will be tracked, and controlled.

In Palm Beach, Florida 200 Alzheimer’s patients were already microchipped by the VeriChip company, for free.

The state of Oklahoma is debating a bill to microchip prisoners of violent crimes, to keep track of them after release. Chipping people is wrong. At the moment, it is a choice to be chipped; before too long it will be mandatory. This is a violation of privacy, as well as a threat to American freedom!

Do your research and say no to the VeriChip!
