Resting on the tail of the Great Bear in the constellation of Ursa Major lies NGC 5585, a spiral galaxy that is more than it appears.
The many stars and clouds of dust and gas that make up NGC 5585, shown here in this Hubble image, contribute only a small fraction of the total mass of the galaxy. As in many galaxies, this discrepancy can be explained by the abundant yet seemingly invisible presence of dark matter, a mysterious material that astronomers can’t directly observe.
The stellar disk of the galaxy extends over 35,000 light-years across. When compared with galaxies of a similar shape and size, NGC 5585 stands out by having a notably different composition. Contributing to the total mass of the galaxy, it contains a far higher proportion of dark matter.
Hot spots of star formation can be seen along the galaxy’s faint spiral arms. These regions shine a brilliant blue, contrasting strikingly against the ever-black background of space.

NASA's Oceans Melting Greenland, or OMG, airborne mission found that most of Greenland's glaciers that empty into the ocean are at greater risk of rapid ice loss than previously understood. OMG's six-year field campaign studied the ocean's role in glacial ice loss by gathering precise measurements of ocean depth, temperature, and salinity in front of more than 220 glaciers. The mission's goal was to clarify our understanding of sea level rise over the next 50 years. This photo of Apusiaajik Glacier was taken near Kulusuk, Greenland, on Aug. 26, 2018, during OMG's field operations.

This 2009 image of Centaurus A shows a spectacular new view of a supermassive black hole's power. Jets and lobes powered by the central black hole in this nearby galaxy are shown by submillimeter data (colored orange) from the Atacama Pathfinder Experiment (APEX) telescope in Chile and X-ray data (colored blue) from the Chandra X-ray Observatory. Visible light data from the Wide Field Imager on the Max-Planck/ESO 2.2 m telescope, also located in Chile, shows the dust lane in the galaxy and background stars. The X-ray jet in the upper left extends for about 13,000 light years away from the black hole. The APEX data shows that material in the jet is travelling at about half the speed of light.

NASA’s OSIRIS-REx completed its last flyover of Bennu around 6 a.m. EDT (4 a.m. MDT) April 7 and is now slowly drifting away from the asteroid; however, the mission team will have to wait a few more days to find out how the spacecraft changed the surface of Bennu when it grabbed a sample of the asteroid.
This image shows a top-down view of asteroid Bennu, with a portion of the asteroid’s equatorial ridge and northern hemisphere illuminated. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 4, 2021, from a distance of about 186 miles (300 km). The spacecraft’s cameras are pointed directly at Bennu’s north pole. Two large equatorial craters are visible on the asteroid’s edge (center and center left). The image was obtained during the mission’s Post-TAG Operations phase, as the spacecraft slowly approached Bennu in preparation for a final observational flyby on April 7.

The second supermoon of 2019 happens Feb. 19. But what’s a supermoon? We asked NASA astronomer Mitzi Adams what’s really going on here. Here’s her answer!
Like the orbits of all bodies in the solar system, the Moon’s orbit around Earth is not circular, it has an oval or elliptical shape, with Earth slightly offset from the center. As a result, there are two distance extremes of each orbit: closest approach, known as perigee, and the farthest, or apogee. When the Moon is at closest approach and within a day or so of being full, it is called a supermoon because the Moon will be at its brightest and largest.
This is an image of a total lunar eclipse that accompanied the first in a trilogy of supermoons in 2019.

This image captures the intensity of the jets and vortices in Jupiter’s North North Temperate Belt.
NASA’s Juno spacecraft took this color-enhanced image at 10:31 p.m. PDT on May 23, 2018 (1:31 a.m. EDT on May 24), as Juno performed its 13th close flyby of Jupiter. At the time, the spacecraft was about 4,900 miles (7,900 kilometers) from the tops of the clouds of the gas giant planet at a northern latitude of about 41 degrees. The view is oriented with south on Jupiter toward upper left and north toward lower right.
The North North Temperate Belt is the prominent reddish-orange band left of center. It rotates in the same direction as the planet and is predominantly cyclonic, which in the northern hemisphere means its features spin in a counter-clockwise direction. Within the belt are two gray-colored anticyclones.
To the left of the belt is a brighter band (the North North Temperate Zone) with high clouds whose vertical relief is accentuated by the low angle of sunlight near the terminator. These clouds are likely made of ammonia-ice crystals, or possibly a combination of ammonia ice and water. Although the region as a whole appears chaotic, there is an alternating pattern of rotating, lighter-colored features on the zone's north and south sides.

Since the beginning of the space program, people have been captivated by big, powerful rockets—like NASA’s Saturn V rocket that sent Apollo to the lunar surface, or the Space Launch System that will produce millions of pounds of thrust as it sends Artemis astronauts back to the Moon.
But what if the most powerful propulsion system in NASA’s toolbox produces less than one pound of thrust while reaching speeds of up to 200,000 mph? What if it costs less, carries more, and uses less fuel?
This radical system is in-space electric propulsion. It can reduce the amount of fuel, or propellant, needed by up to 90% compared to chemical propulsion systems, saving millions in launch costs while providing greater mission flexibility.
In this image, a solar electric propulsion Hall Effect thruster is being tested under vacuum conditions at NASA.

Sorry Charlie Brown, NASA's Hubble Space Telescope is taking a peek at what might best be described as the "Greater Pumpkin," that looks like a Halloween decoration tucked away in a patch of sky cluttered with stars. What looks like two glowing eyes and a crooked carved smile is a snapshot of the early stages of a collision between two galaxies. The entire view is nearly 109,000 light-years across, approximately the diameter of our Milky Way.
The overall pumpkin-ish color corresponds to the glow of aging red stars in two galaxies, cataloged as NGC? 2292 and NGC? 2293, which only have a hint of spiral structure. Yet the smile is bluish due to newborn star clusters, spread out like pearls on a necklace, along a newly forming dusty arm. The glowing eyes are concentrations of stars around a pair of supermassive black holes. The scattering of blue foreground stars makes the "pumpkin" look like it got all glittery for a Halloween party.

The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion).
The oblate shells of ESO 455-10, previously held tightly together as layers of its central star, not only give this planetary nebula its unique appearance, but also offer information about the nebula. Seen in a field of stars, the distinct asymmetrical arc of material over the north side of the nebula is a clear sign of interactions between ESO 455-10 and the interstellar medium.
The interstellar medium is the material such as diffuse gas between star systems and galaxies. The star at the center of ESO 455-10 allows Hubble to see the interaction with the gas and dust of the nebula, the surrounding interstellar medium, and the light from the star itself. Planetary nebulae are thought to be crucial in galactic enrichment as they distribute their elements, particularly the heavier metal elements produced inside a star, into the interstellar medium which will in time form the next generation of stars.

High above the turn of the world, a mammoth construct largely made of aluminum, titanium, and human ingenuity – big as a football field, easily seen from the ground with the naked eye – skates forever along the edge of the sky, while its pioneering crew works to prepare the way for new human journeys to the Moon, Mars, and beyond.
NASA is marking 20 years of continuous crew operations in Earth orbit aboard the International Space Station, comprised of a 360-foot integrated “backbone” truss structure, four sets of 112-foot-long solar arrays, and 16 pressurized modules containing crew living quarters and state-of-the-art laboratories. Designed, built and tested by NASA and its 15 partner nations, its elements launched to orbit one by one over a 13-year period, the station is one of a kind. It weighs more than 925,000 pounds. It has roughly the interior volume of a six-bedroom house. It’s often the third-brightest object in the night sky.
The structure provided the backbone to transform the station into the orbiting laboratory it is today – and many of its largest structures were built, tested, and readied for flight by teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, working in partnership with American contractors and international firms around the world.

Could dying stars hold the secret to looking younger? New evidence from NASA’s Hubble Space Telescope suggests that white dwarf stars could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters, which contain the oldest known stars in the universe.
These results challenge the prevalent view of white dwarfs as inert, slowly cooling burned-out stars where nuclear fusion has stopped. Now, an international group of astronomers has discovered the first evidence that white dwarfs can slow down their rate of aging by burning hydrogen on their surfaces.
To investigate the physics underpinning white dwarf evolution, astronomers compared cooling white dwarfs in two massive collections of stars: the globular clusters M13 and M3. These two clusters share many physical properties such as age and metallicity, but the populations of stars which will eventually give rise to white dwarfs are different. This makes M13 and M3 together a perfect natural laboratory in which to test how different populations of white dwarfs cool.

This week in 1965, SA-9, the eighth Saturn flight, launched from Cape Kennedy Launch Complex in Florida. This was the first Saturn flight with an operational payload – the Pegasus I meteoroid detection satellite. Pegasus was developed by Fairchild Stratos Corporation for NASA through the agency’s Marshall Space Flight Center. A Pegasus satellite also flew aboard the SA-8 and SA-10 missions in 1965. After being placed in orbit around Earth, the satellite electronically recorded the size and frequency of particles in space and compared the performance of protected and unprotected solar cells as important preliminaries to crewed flights to the Moon.

A fiery meteor streaked across the morning skies in southern Mississippi yesterday on April 27, 2022.
More than 30 eyewitnesses in the states of Arkansas, Louisiana, and Mississippi reported seeing a bright fireball at 8:03 a.m. CDT. The sighting was soon followed by numerous reports of loud booms heard in Claiborne County, Mississippi, and surrounding counties.
Approximately 22,000 miles out in space, NOAA’s Geostationary Lightning Mappers (GLM) onboard the Geostationary Operational Environmental Satellites (GOES) 16 and 17 detected several bright flashes associated with the fragmentation’s of this bolide, or exceptionally bright meteor, which was first spotted 54 miles above the Mississippi River near the Mississippi town of Alcorn.

This galaxy cluster, Abell 2163, from the Chandra X-ray Observatory is representative of over 80 clusters that were used to track the effects of dark energy on these massive objects over time. Most of the matter in galaxy clusters is in the form of very hot gas, which emits copious amounts of X-rays. By studying clusters across large distances, astronomers have determined that dark energy has stifled their growth.

This view of sample site Nightingale on asteroid Bennu is a mosaic of images collected by NASA’s OSIRIS-REx spacecraft on March 3. These images were captured when the spacecraft performed an 820-foot (250-meter) reconnaissance pass over site Nightingale, which at the time was the closest the site had been imaged. The low-altitude pass provided high-resolution imagery for the OSIRIS-REx team to identify the best location within the site to target for sample collection. Sample site Nightingale is located in the relatively clear patch just above the crater’s center – visible in the center of the image. The large, dark boulder located at the top right measures 43 feet (13 meters) on its longest axis. The mosaic is rotated so that Bennu’s east is at the top of the image. Nightingale is the primary sample collection site for the OSIRIS-REx mission. OSIRIS-REx is scheduled to make its first sample collection attempt at site Nightingale on Oct. 20.

Just two days after leaving the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, in a specialized container carefully strapped to the deck of a semi-trailer truck, NASA’s Double Asteroid Redirection Test (DART) spacecraft arrived in California — its final stop here on Earth.
DART will be the world’s first mission to test planetary defense techniques, demonstrating one mitigation method of asteroid deflection, called kinetic impact. DART will impact the small asteroid moonlet Dimorphos, which orbits a larger companion, Didymos, in a binary asteroid system to change its orbital period.
Inside a cleanroom at Johns Hopkins APL, the DART spacecraft being moved into a specialized shipping container that headed across the country to Vandenberg Space Force Base near Lompoc, California, where DART is scheduled to launch from late next month.

This week in 1991, space shuttle Columbia, mission STS-40, launched from NASA’s Kennedy Space Center carrying the fifth Spacelab mission. The Spacelab Life Sciences-1 module was the first Spacelab mission dedicated solely to life sciences. The main purpose of the mission was to study the mechanisms, magnitudes and time courses of certain physiological changes that occur during spaceflight and was designed to explore the responses of the heart, lungs, blood vessels, kidneys and hormone-secreting glands to microgravity and related body fluid shifts. Today, NASA's Marshall Space Flight Center manages the Life Sciences Glovebox and monitors International Space Station science and communications from its Payload Operations Integration Center. Scheduled to launch to the station in September 2018, the Life Sciences Glovebox will be used to study the long-term impact of microgravity on human physiology, revealing new ways to improve life on Earth while protecting human explorers during long-duration deep space missions.

This week in 2007, space shuttle Endeavour, mission STS-118, landed at NASA’s Kennedy Space Center following a successful 14-day mission to the International Space Station. Endeavour carried a payload that included a third starboard truss segment -- S5 -- a SPACEHAB module, and the external stowage platform 3, which was attached to the P3 truss. Here, astronaut Rick Mastracchio participates in the second session of extravehicular activity to perform construction and maintenance on the orbiting laboratory.

The Interim Cryogenic Propulsion Stage for the second flight of NASA’s Space Launch System (SLS) rocket arrived in Florida on July 28 for the final phase of production. The stage and its single RL10 engine provide the in-space propulsion needed to send NASA’s Orion spacecraft and its crew on a precise trajectory to the Moon for Artemis II, the first crewed mission of NASA’s Artemis lunar missions. It is the first piece of the rocket for the Artemis II flight to arrive in Florida. Boeing and United Launch Alliance, the contractor team for the stage, shipped the Interim Cryogenic Propulsion Stage from ULA’s facilities in Decatur, Alabama, to its Delta IV Operation Center at Cape Canaveral Space Force Station. The stage will undergo final processing and checkout before it is transported to NASA’s Kennedy Space Center for launch preparations.
With Artemis, NASA will land the first woman and the first person of color on the lunar surface and establish long-term exploration at the Moon in preparation for human missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

The Science Verification Test for NASA’s Advanced Plant Experiment-08 (APEX-08) testing Arabidopsis thaliana, a plant scientists routinely use for research, takes place inside the Veggie growth chamber at NASA’s Kennedy Space Center in Florida on Nov. 6, 2020. The test is part of the process for demonstrating readiness for space research ahead of its flight on SpaceX’s 23rd Commercial Resupply Services mission to the International Space Station. The APEX-08 study includes making genetic alterations that elicit a response in a group of organic compounds that modulate plant responses to environmental stress.

More than 40 high-powered, amateur rockets successfully launched April 15, in North Alabama, each carrying a scientific payload nearly one-mile-high above ground level, as part of a NASA student competition.
The launches were the culminating event of NASA’s Student Launch, a competition tasking students to design, build, and launch rockets in support of NASA research. When students were asked to describe learning from and working with NASA engineers, excited was the word used most often.
Here, students watch a high-powered amateur rocket launch during NASA’s 2023 Student Launch competition near NASA’s Marshall Space Flight Center in Huntsville, Alabama.

The next full Moon will be Wednesday night, August 30, 2023, appearing opposite the Sun (in Earth-based longitude) at 9:36 PM EDT. The planet Saturn, just a few days from its closest and brightest for the year, will appear near the Moon. As evening twilight ends (at 8:42 PM) Saturn will be 5 degrees to the upper right of the Moon, and will appear to swing clockwise around the Moon as the evening progresses. The Moon will appear full for 3 days around the peak of the full Moon, from Tuesday night to Friday morning.
This will be a supermoon. Publications use different thresholds for deciding which Moons qualify as "super," but all agree that in 2023 the two full Moons in August qualify.
This full Moon will be the second full Moon in August, making it a Blue Moon by the newer definition introduced by Sky & Telescope magazine in 1946. The older definition of Blue Moon, dating back to at least the 1500s, is the name for the third full Moon in a season that has four Moons. By this definition, the full Moon in August 2024 will be the Blue Moon and this full Moon, as the last full Moon of summer, shares some of the seasonal names from my posting for the August 1 full Moon. Neither of these definitions has anything to do with the color of the Moon, so the Blue Moon will not actually look blue.
This full Moon corresponds with the Hindu festival Raksha Bandhan, also called Rakhi or Rakhi Purnima, celebrating the bond between brothers and sisters. One of the traditions is for sisters of all ages to tie a rakhi (a cotton bracelet) around their brother's wrist, receiving a gift from the brother in return, as a sign of the continuing bond between them. The term "Raksha Bandhan" translates as "the bond of protection, obligation, or care."
Here, the Moon, or supermoon, is seen as it rises behind the U.S. Capitol, Monday, March 9, 2020, in Washington, DC.
