the hypotheses of the astronomer; let it, in short, be the secretary and record-keeper of whomsoever needs absolute material accuracy for professional reasons. So far so good.... But if once it be allowed to impinge on the sphere of the intangible and the imaginary, on anything that has value solely because man adds something to it from his soul, then woe betide us!

Most astronomers believe that the universe began with a Big Bang, about 14 billion years ago. The entire universe was then contained in a bubble that was
thousands of times smaller than the head of a pin (needle).
It was hotter and heavier than anything we could imagine.
And at the same time it exploded. Thus the universe as we know it was born. Time, space and material all started with that one big bang. In a fraction of a second, the universe grew from smaller than an atom to larger than a galaxy. And it's getting bigger and bigger, at a limited pace. Even now it is expanding.

To the eye, the moon can look full for a few nights in succession. To astronomers, though, the full moon occurs in a single instant, when the moon is 180 degrees opposite the sun in ecliptic longitude. This full moon instant occurs on February 27. For us in the U.S., that’s February 27 at 3:17 a.m. EST, 2:17 a.m. CST, 1:17 a.m. MST, at 12:17 a.m. PST.

The Ulugh Beg Observatory is an observatory in Samarkand, Uzbekistan. Built in the 1420s by the Timurid astronomer Ulugh Beg, it is considered by scholars to have been one of the finest observatories in the Islamic world. Some of the famous Islamic astronomers who worked at the observatory include Al-Kashi, Ali Qushji, and Ulugh Beg himself. The observatory was destroyed in 1449 and rediscovered in 1908.
In 1420, the great astronomer Ulugh Beg built a madrasah in Samarkand, named the Ulugh Beg Madrasah. It became an important center for astronomical study and only invited scholars to study at the university whom he personally approved of and respected academically and at its peak had between 60 and 70 astronomers working there. In 1424, he began building the observatory to support the astronomical study at the madrasah and it was completed five years later in 1429. Beg assigned his assistant and scholar Ali Qushji to take charge of the Ulugh Beg Observatory which was called Samarkand Observatory at that time. He worked there till Ulugh Beg was assassinated. Other notable astronomers made observations of celestial movements at the observatory, including Qāḍīzāda al-Rūmī and Jamshid Kashani.
However, the observatory was destroyed by religious fanatics in 1449 and was only re-discovered in 1908, by an Uzbek-Russian archaeologist from Samarkand named V. L. Vyatkin, who discovered an endowment document that stated the observatory's exact location.
The Ulug Beg Observatory Museum was built in 1970 to commemorate Ulug Begh. Ulug Beg's Star Charts, the Zij-i Sultani are kept in the museum although they are copies; the original drawings were stolen from Uzbekistan by the British and are in Oxford, England.
C/2020 F3 (NEOWISE) or Comet NEOWISE is a retrograde comet with a near-parabolic orbit discovered on March 27, 2020, by astronomers during the NEOWISE mission of the Wide-field Infrared Survey Explorer (WISE) space telescope. At that time, it was a 18th-magnitude comet, located 2 AU (300 million km; 190 million mi) away from the Sun and 1.7 AU (250 million km; 160 million mi) away from Earth.
By July 2020, it was bright enough to be visible to the naked eye. It is one of the brightest comets in the northern hemisphere since Comet Hale–Bopp in 1997 and was widely observed as being clearly visible with the naked eye. It has been considered by Seiichi Yoshida and Farmer's Almanac as a possible great comet, and NASA noted that it could become known as a great comet.
However, this distinction is usually reserved for comets that are easily observable with the naked eye, even with low to moderate light pollution. Under dark skies, it can be clearly seen with the naked eye and might remain visible to the naked eye throughout most of July 2020, at least until July 23, the point of the comet's closest approach to Earth. Prior to that date, the comet will be getting closer to Earth as it moves farther away from the Sun. As of July 18, the comet is about magnitude 3. Near urban areas binoculars are required to locate the comet.
For observers in the northern hemisphere, in the morning, the comet appears very low above the north-eastern horizon, below Capella. In the evening, the comet can be seen low in the north-western sky. The comet can be seen in the morning and evening because it is circumpolar north of the 45th parallel north. On July 17, Comet NEOWISE entered the constellation of Ursa Major, below the asterism of the Big Dipper (The Plough). (If Ursa Major were upright, it would be on the right of the Big Dipper, as of July 15th.)
Comet NEOWISE made its closest approach to the Sun (perihelion) on July 3, 2020, at a distance of 0.29 AU (43 million km; 27 million mi). This passage increases the comet's orbital period from about 4400 years to about 6700 years. Its closest approach to Earth will occur on July 23, 2020, 01:14 UT, at a distance of 0.69 AU (103 million km; 64 million mi) while located in the constellation of Ursa Major.
Nicholas of Cusa (1401 – 11 August 1464), also referred to as Nicholas of Kues and Nicolaus Cusanus, was a German philosopher, theologian, Catholic cleric, jurist, mathematician and astronomer. One of the first German proponents of Renaissance humanism, he made spiritual and political contributions in European history. A notable example of this is his mystical or spiritual writings on "learned ignorance," as well as his participation in power struggles between Rome and the German states of the Holy Roman Empire.
As papal legate to Germany from 1446, he was appointed cardinal for his merits by Pope Nicholas V in 1448 and Prince–Bishop of Brixen two years later. In 1459, he became vicar general in the Papal States.
Nicholas has remained an influential figure. In 2001, the sixth centennial of his birth was celebrated on four continents and commemorated by publications on his life and work. (Wikipedia) Bernkastel-Kues, Germany
The Horsehead Nebula, also known as Barnard 33, is a dark Nebula in the constellation Orion. The Nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt and is part to the much larger Orion Molecular Cloud Complex.
The Nebula was first recorded in 1888 by Scottish astronomer William Fleming on a photographic plate taken at the Harvard College Observatory. The Horsead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse's head.
Due to its recognizable shape the Horsehead Nebula is one of the most famous celestial objects.
The Flame Nebula, designated as NGC 2024 and SH2-277, is an emission nebula in the constellation of Orion. It's about 900 to 1,500 light-years away
The bright star Alnitak, the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electron away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electron and ionized hydrogen recombine

Astronomers are using the NASA/ESA Hubble Space Telescope to study auroras — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, currently on its way to Jupiter.
Jupiter, the largest planet in the solar system, is best known for its colorful storms, the most famous being the Great Red Spot. Now astronomers have focused on another beautiful feature of the planet, using Hubble's ultraviolet capabilities.
The extraordinary vivid glows shown in the new observations are known as auroras. They are created when high-energy particles enter a planet’s atmosphere near its magnetic poles and collide with atoms of gas. As well as producing beautiful images, this program aims to determine how various components of Jupiter’s auroras respond to different conditions in the solar wind, a stream of charged particles ejected from the sun.
This observation program is perfectly timed as NASA’s Juno spacecraft is currently in the solar wind near Jupiter and will enter the orbit of the planet in early July 2016. While Hubble is observing and measuring the auroras on Jupiter, Juno is measuring the properties of the solar wind itself; a perfect collaboration between a telescope and a space probe.
“These auroras are very dramatic and among the most active I have ever seen”, said Jonathan Nichols from the University of Leicester, U.K., and principal investigator of the study. “It almost seems as if Jupiter is throwing a firework party for the imminent arrival of Juno.” Read more: go.nasa.gov/294QswK

Armagh Observatory is an astronomical research institute in Armagh, Northern Ireland. Around 25 astronomers are based at the observatory, studying stellar astrophysics, the Sun, Solar System astronomy and Earth's climate.
Astronomers have learned that the age of a star can be determined by the rate of its spin. Stars spin slower as they age.
So do people. Still, even with cataracts, fading hearing, and memories mistier by the day – the combination of experience, reduced options, and a growing sense of mortality tends to crystalize things. There is a certain increased clarity and awareness.

"We're made of star stuff," astronomer Carl Sagan famously said. Nuclear reactions that happened in ancient stars generated much of the material that makes up our bodies, our planet and our solar system. When stars explode in violent deaths called supernovae, those newly formed elements escape and spread out in the universe.
One supernova in particular is challenging astronomers' models of how exploding stars distribute their elements. The supernova SN 2014C dramatically changed in appearance over the course of a year, apparently because it had thrown off a lot of material late in its life. This doesn't fit into any recognized category of how a stellar explosion should happen. To explain it, scientists must reconsider established ideas about how massive stars live out their lives before exploding.
"This 'chameleon supernova' may represent a new mechanism of how massive stars deliver elements created in their cores to the rest of the universe," said Raffaella Margutti, assistant professor of physics and astronomy at Northwestern University in Evanston, Illinois. Margutti led a study about supernova SN 2014C published this week in The Astrophysical Journal.

Galileo Galilei was an important Italian scientist, physicist, mathematician, astronomer and philosopher. His scientific contribution started a new era in the history of astronomy, he was the first astronomer to access new knowledge using the telescope. He defended the concept that the Earth was not the center of the universe.
Galileo Galilei was born in Pisa, Italy, on February 15, 1564, son of Vincenzo Galilei and Julia Ammannati. His parents noticed Galilei's great intelligence and special aptitudes from an early age. The boy showed an interest in the arts and performed excellent paintings, demonstrating manual skill and creativity to manufacture toys and contraptions. He played the organ and zither with aplomb. Thus, Galilei excelled in studies at the Sunday school in Vallombrosa and planned to enter the monastery, but his father did not agree with the idea and enrolled him to study medicine at the University of Pisa. Two years after joining, he dropped out of the course and went to dedicate himself to the study of mathematics. The move did not please his father, and Galilei ended up dropping out of the University in 1585. He did not complete any degrees, but in the same year he went to Florence and began giving private lessons to support himself. He stood out for his research in geometry and continued with his mathematical studies.
It was at this time that he invented the hydrostatic balance, a mechanism that would be published in a detailed treatise in the year 1644. In 1589, in recognition of his scientific contributions and brilliant reasoning, he was appointed to the chair of mathematics at the University of Pisa. He was not welcomed by teachers, as he was only 25 years old, had incomplete academic training and publicly discredited Aristotle's established theories. In 1590 Galilei published a treatise on the motion of bodies. In 1591 he was removed from the professorship, after succumbing to intrigues and disputes with Aristotle's supporters. In 1592 he was appointed by the Senate of Venice to teach mathematics at the University of Padua, a position he would hold for 18 years. In 1609 he built a telescope based on the one previously invented by Hans Lippershey in Holland. Galilei made meticulous observations of the sky and incredible discoveries: he located the four largest moons of Jupiter and the mountains and craters on the Moon's surface. And when he detected spots present on the Sun's surface, the discovery helped to prove his theory that the star rotated on an axis. He investigated Saturn and observed what appeared to be two fixed moons, which were the edges of Saturn's ring system, but Galilei's telescope was not accurate enough to determine exactly what those points were.
His findings were collected and published in March 1610 in the book “The Messenger of the Stars”. The work was acclaimed and also generated much controversy, as Galilei publicly defended Nicolaus Copernicus' theory that the Sun was the center of our Solar System, not the Earth. At that time, the Catholic Church fully controlled science and held the opposite view, that the center was the Earth.
In 1616 Galilei was cornered by the authorities of the Inquisition and threatened with the death penalty if he did not publicly deny the scientific truths he had proved. He was expressly prohibited from teaching and propagating ideas that were contrary to the position of the Church. Even so, in 1632 he published the "Dialogue Concerning the Two Greatest Systems of the Universe", causing the Church's total rejection and intolerance. Prevented from continuing with his research and theories, the scientist retired to his castle located in Arcetri, a village near Florence, where he dedicated himself to pursuing his experiments alone.
Galileo Galilei died on January 8, 1642 in Arcetri, Italy. He was almost blinded by the observation of sunspots done without adequate protection for decades. Three hundred and fifty years later, through Pope John Paul II, on October 31, 1992, the Catholic Church formally recognized the legitimacy of Galilei's theories.

I’m not sure what’s going on with the clock, the one showing the time as 10:40am is correct, the front facing one seems to be having a few problems, or maybe there’s something going on that I don’t know about.

Leiden Observatory ( near the Hortus botanicus ) before dusk sets in, as seen from de Witte Singel.
Leiden Observatory (Sterrewacht Leiden in Dutch) is an astronomical observatory in the city of Leiden, Netherlands. It was established by Leiden University in 1633, to house the quadrant of Snellius, and is the oldest operating University observatory in the world (before this, astronomy taught at medieval universities tended to be of a more theoretical nature, and any observations were usually done with private equipment rather than at University observatories —see this timeline).
The original observatory used observing platforms on the roof of the main university building at the Rapenburg. In 1860 a large, modern observatory was erected at the Witte Singel. This building was the home of the astronomy department until it moved to the science campus north-west of the city centre in 1974. Although professional astronomical observations are no longer carried out from Leiden itself, the department still calls itself Leiden Observatory. Today's astronomers instead travel to the big observatories, e.g. ESO's VLT in Chile.
The astronomy department (Sterrewacht Leiden) is the largest in the Netherlands and is internationally renowned, performing research in a wide range of astronomical disciplines.
A number of prominent astronomers and physicists have done work at Leiden Observatory, including Willem de Sitter, Ejnar Hertzsprung, and Jan Oort, all of whom have served as Directors. Another famous employee was Jacobus Kapteyn. The Observatory has recently been renovated. Source: Wikipedia.
The Eskimo Nebula (NGC 2392), also known as the Clownface Nebula[3] or Caldwell 39, is a bipolar[4] double-shell[5] planetary nebula (PN).
It is tiny! I had to work hard to get some detail drawn out of my files for this one. It is smaller than the thickness of a greeting card held at arms length!! (about 1 arcminute across)
It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star. The outer disk contains unusual light-year-long filaments.
Set out to capture the Delta Aquarids Meteor shower, saw plenty of meteors but they were never in the direction I was pointing my camera! Not wanting to leave without "the shot" I had this idea I wanted to try out too. It was bloody cold and windy standing up there!
Fired using Cactus V5 triggers using their "remote shutter feature".
Discovered in 1898 by American astronomer Edward Foster Coddington, Coddington's Nebula is not actually a nebula but rather an irregular dwarf galaxy and part of the M81 galaxy group.
Imaged in January 2017 with an Altair Astro 6" RC and Atik 460ex. Captured in SGPro and processed Pixinsight and CS5.
NGC6872, discovered in 1835 by English astronomer John Herschel, is a large barred spiral galaxy in the constellation Pavo. It is approximately 212 million light-years from Earth and is believed to be five billion years old. It is interacting with the lenticular galaxy IC 4970, which is apparently less than one twelfth as large.
This is an extremely small, distant object, that needs a lot more imaging time to do it justice. It is infact the most distant object we have imaged. The night started off well, but by midnight there were 50km per hour gusts of wind which put an end to the night, and I was only able to get 4 hours. I am still very happy with how it turned out.

In 1620 an English mathematician and astronomer named Edmund Gunter described a surveyor's chain with 100 links, measuring 66 feet (22 yards or 4 poles) overall. By this design, one square chain equals 484 square yards, ten square chains equal an acre, and eighty chains equal a mile.
Oopps , sorry not that sort of chain - this is a very long chain made up from many many links with each link being about 8 inches or 20 cms long .
Taken while I had the chance for Saturday Self Challenge 11/06/2022 -- Multiple . ( and in this case -- Links in a chain ) .
Well this rather long chain is made up of a lot of links laying on the slip way of the King Harry Ferry . If you notice in the top left there is another chain in tension , this is an active chain and one of a pair that the King Harry Ferry hauls itself backwards and forwards on crossing the River Fal just below Trelissick Gardens where we were staying .

In 1054, Chinese astronomers took notice of a “guest star” that was, for nearly a month, visible in the daytime sky. The “guest star” they observed was actually a supernova explosion, which gave rise to the Crab Nebula, a six-light-year-wide remnant of the violent event.
With an apparent magnitude of 8.4 and located 6,500 light-years from Earth in the constellation Taurus, the Crab Nebula can be spotted with a small telescope and is best observed in January. The nebula was discovered by English astronomer John Bevis in 1731, and later observed by Charles Messier who mistook it for Halley’s Comet. Messier’s observation of the nebula inspired him to create a catalog of celestial objects that might be mistaken for comets.
The colors in this image do not match exactly what we would see with our eyes but yield insight into the composition of this spectacular stellar corpse. The reddish filaments are the tattered remains of the star and consist mostly of hydrogen. The blue in the filaments in the outer part of the nebula represents neutral oxygen. These (and other) elements were expelled during the supernova explosion.
A rapidly spinning neutron star (the ultra-dense core of the exploded star) is embedded in the center of the Crab Nebula. The neutron star, like a lighthouse, ejects twin beams of radiation that make it appear to pulse 30 times per second as it rotates. Text from NASA\Goddard

This NASA/ESA Hubble Space Telescope image features a spiral galaxy, named UGC 10043. We don’t see the galaxy’s spiral arms because we are seeing it from the side. Located roughly 150 million light-years from Earth in the constellation Serpens, UGC 10043 is one of the somewhat rare spiral galaxies that we see edge-on.
This edge-on viewpoint makes the galaxy’s disk appear as a sharp line through space, with its prominent dust lanes forming thick bands of clouds that obscure our view of the galaxy’s glow. If we could fly above the galaxy, viewing it from the top down, we would see this dust scattered across UGC 10043, possibly outlining its spiral arms. Despite the dust’s obscuring nature, some active star-forming regions shine out from behind the dark clouds. We can also see that the galaxy’s center sports a glowing, almost egg-shaped ‘bulge’, rising far above and below the disk. All spiral galaxies have a bulge similar to this one as part of their structure. These bulges hold stars that orbit the galactic center on paths above and below the whirling disk; it’s a feature that isn’t normally obvious in pictures of galaxies. The unusually large size of this bulge compared to the galaxy’s disk is possibly due to UGC 10043 siphoning material from a nearby dwarf galaxy. This may also be why its disk appears warped, bending up at one end and down at the other.
Like most full-color Hubble images, this image is a composite, made up of several individual snapshots taken by Hubble at different times, each capturing different wavelengths of light. One notable aspect of this image is that the two sets of data that comprise this image were collected 23 years apart, in 2000 and 2023! Hubble’s longevity doesn’t just afford us the ability to produce new and better images of old targets; it also provides a long-term archive of data which only becomes more and more useful to astronomers.
