C/2020 F3 or “Comet NEOWISE” is viewed above the 16th-century Varlaam abbey, on top of the geologically unique Meteora, Greece, at twilight.
Photograph cordially dedicated to Mrs. Vicky KALOGERA, Haven Professor of Physics and Astronomy and CIERA Director at Northwestern University, Illinois, US.
The comet was captured on July 19, 2020 at 22:01’ (local time) at a 20° altitude above horizon and azimuth of 316° 16’. The comet’s visual magnitude was 3.45, its distance from Earth was 0.71 AU, whereas its distance from the Sun was 0.56 AU.
The Varlaam abbey or “monastery” was built in 1517-1518 on a 1,808 ft high (551 m) rock formation. The impressive and lofty rock formations are collectively known as Meteora: The sandstone megaliths’ height varies 1,000-2,067 ft (300-630 m). The rock masses were formed 60 million years ago, are geologically unique and listed in UNESCO world heritage sites.
This photograph was made by stacking 21 light frames by Starry Landscape Stacker (version 1.8.0; algorithm: Min Horizon Noise).

Using data from NASA’s Imaging X-ray Polarimetry Explorer (IXPE), international researchers have uncovered new information about the Tycho supernova remnant, an exploded star in the constellation Cassiopeia, the light from which was first seen on Earth in 1572. The results offer new clues about how shock waves created by these titanic stellar explosions accelerate particles to nearly the speed of light, and reveal, for the first time, the geometry of the magnetic fields close to the supernova’s blast wave, which forms a boundary around the ejected material, as seen in this composite image. IXPE data (dark purple and white) have been combined with data from NASA’s Chandra X-ray Observatory (red and blue) and overlaid with the stars in the field of view as captured by the Digitized Sky Survey.

For the first time, astronomers have measured and mapped polarized X-rays from the remains of an exploded star, using NASA’s Imaging X-ray Polarimetry Explorer (IXPE). The findings, which come from observations of a stellar remnant called Cassiopeia A, shed new light on the nature of young supernova remnants, which accelerate particles close to the speed of light.
Launched on Dec. 9, 2021, IXPE, a collaboration between NASA and the Italian Space Agency, is the first satellite that can measure the polarization of X-ray light with this level of sensitivity and clarity.
All forms of light – from radio waves to gamma rays – can be polarized. Unlike the polarized sunglasses we use to cut the glare from sunlight bouncing off a wet road or windshield, IXPE’s detectors maps the tracks of incoming X-ray light. Scientists can use these individual track records to figure out the polarization, which tells the story of what the X-rays went through.
Cassiopeia A (Cas A for short) was the first object IXPE observed after it began collecting data. One of the reasons Cas A was selected is that its shock waves – like a sonic boom generated by a jet – are some of the fastest in the Milky Way. The shock waves were generated by the supernova explosion that destroyed a massive star after it collapsed. Light from the blast swept past Earth more than three hundred years ago.
This composite image shows the Cas A supernova remnant, a structure resulting from the explosion of a star in the Cassiopeia constellation. The blues represent data from the Chandra Observatory, the turquoise is from NASA's Imaging X-ray Polarimetry Explorer (called IXPE), and the gold is courtesy of the Hubble Telescope.

Four composite images deliver dazzling views from NASA's Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. Each image combines Chandra's X-rays — a form of high-energy light — with infrared data from previously released Webb images, both of which are invisible to the unaided eye. Data from NASA's Hubble Space Telescope (optical light) and retired Spitzer Space Telescope (infrared), plus the European Space Agency's XMM-Newton (X-ray) and the European Southern Observatory's New Technology Telescope (optical) is also used. These cosmic wonders and details are made available by mapping the data to colors that humans can perceive.
NGC 346 is a star cluster in a nearby galaxy, the Small Magellanic Cloud, about 200,000 light-years from Earth. Webb shows plumes and arcs of gas and dust that stars and planets use as source material during their formation. The purple cloud on the left seen with Chandra is the remains of a supernova explosion from a massive star. The Chandra data also reveals young, hot, and massive stars that send powerful winds outward from their surfaces. Additional data from Hubble and Spitzer is included, along with supporting data from XMM-Newton and ESO’s New Technology Telescope. (X-ray: purple and blue; infrared/optical: red, green, blue)

The photograph WITH explanatory labels and arrows pointing to the planets
James Weldon Johnson’s poem “I hear the stars still singing” invites all of us to think about astrophysicists. Since November 2016 Professor Vicky Kalogera and her colleagues have been able to actually detect the gravitational waves generated by stars’ and black holes’ collisions billions of years ago. The LIGO research teams don’t merely detect and record gravitational waves, but they can also decipher the precise information that the convey from the past and they can repsesent them by sound waves.
Yes, nowadays astrophysicists can actually hear the stars still singing today, even if their song was produced billions of years ago. So the the stars’ listener, Prof. Kalogera this photograph is dedicated along with the poem lines:
“I hear the stars still singing
To the beautiful, silent night,
As they speed with noiseless winging…”
When the Milky Way’s galactic centre was shot (Sep. 08, 2020, 21:42’ UTC+3), its elevation (altitude) was 17.8° above horizon and its azimuth 201.8°
This photograph of the Milky Way was made by stacking 29 light frames by Starry Landscape Stacker (minimum horizon noise algorithm).
Jupiter and Saturn are clearly viewed to the left of the Milky Way, at an apparent angular distance of 8° 17’ between them.
Chandra's image of the elliptical galaxy NGC 4697 reveals diffuse hot gas dotted with many point-like sources. As in the elliptical galaxies, NGC 4649 and NGC 1553, the point-like sources are due to black holes and neutron stars in binary star systems. Material pulled off a normal star is heated and emits X-radiation as it falls toward its black hole or neutron star companion.
Black holes and neutron stars are the end state of the brightest and most massive stars. Chandra's detection of numerous neutron stars and black holes in this and other elliptical galaxies shows that these galaxies once contained many very bright, massive stars, in marked contrast to the present population of low-mass faint stars that now dominate elliptical galaxies.
An unusually large number of the binary star X-ray sources in NGC 4697 are in "globular star clusters," round balls of stars in the galaxy that contain about one million stars in a volume where typically only one would be found. This suggests that the extraordinarily dense environment of globular clusters may be a good place for black holes or neutron stars to capture a companion star.
The origin of the hot gas cloud enveloping the galaxy is not known. One possibility is that the gas lost by evaporation from normal stars- so-called stellar winds - is heated by these winds and by supernova explosions.

NGC 1672 is a spiral galaxy, but one that astronomers categorize as a “barred” spiral. In regions close to their centers, the arms of barred spiral galaxies are mostly in a straight band of stars across the center that encloses the core, as opposed to other spirals that have arms that twist all the way to their core. The Chandra data reveals compact objects like neutron stars or black holes pulling material from companion stars as well as the remnants of exploded stars. Additional data from Hubble (optical light) helps fill out the spiral arms with dust and gas, while Webb data shows dust and gas in the galaxy’s spiral arms.

The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1,450 light-years from Earth.
V 372 Orionis is a particular type of variable star known as an Orion Variable. These young stars experience some tempestuous moods and growing pains, which are visible to astronomers as irregular variations in luminosity. Orion Variables are often associated with diffuse nebulae, and V 372 Orionis is no exception; the patchy gas and dust of the Orion Nebula pervade this scene.

Centaurus A sports a warped central disk of gas and dust, which is evidence of a past collision and merger with another galaxy. It also has an active galactic nucleus that periodically emits jets. It is the fifth brightest galaxy in the sky and only about 13 million light-years away from Earth, making it an ideal target to study an active galactic nucleus – a supermassive black hole emitting jets and winds – with NASA's upcoming James Webb Space Telescope.

M86 lies in the heart of the Virgo Cluster of galaxies.
The Virgo Cluster is a cluster of galaxies whose center is 53.8 ± 0.3 Million light years away in the constellation Virgo. Comprising approximately 1300 (and possibly up to 2000) member galaxies, the cluster forms the heart of the larger Virgo Supercluster, of which the Local Group (containing our Milky Way galaxy) is a member.
On my picture you could see M86 as the largest galaxy but you could observe more than a hundred galaxies more, on the annotated version you could find all the information (please, see comments).

NASA's Chandra X-ray Observatory captured a spectacular image of G292.0+1.8, a young, oxygen-rich supernova remnant with a pulsar at its center surrounded by outflowing material. Astronomers know that pulsars are formed in supernova explosions, but they are currently unable to identify what types of massive stars must die in order for a pulsar to be born. Now that Chandra has revealed strong evidence for a pulsar in G292.0+1.8, astronomers can use the pattern of elements seen in the remnant to make a much closer connection between pulsars and the massive stars from which they form.
This 2001 Chandra image shows a rapidly expanding shell of gas that is 36 light years across and contains large amounts of elements such as oxygen, neon, magnesium, silicon and sulfur. Embedded in this cloud of multimillion degree gas is a key piece of evidence linking neutron stars and supernovas produced by the collapse of massive stars.
Standing out at higher X-ray energies, astronomers found a point-like source surrounded by features strikingly similar to those found around the Crab Nebula and Vela pulsars. These features, together with the X-ray spectrum of the central source and surrounding nebula, provide strong evidence that a rapidly spinning neutron star is responsible for the central observed X-radiation.
Astronomers believe that an oxygen-rich supernova explosion is triggered by the collapse of the core of a massive star to form a neutron star, releasing tremendous amounts of energy in the process. "This finding is very important, since it would allow us to conclusively associate this young, oxygen-rich supernova remnant with a core collapse, massive star supernova explosion," said John P. Hughes of Rutgers University, lead author of a paper describing the research which appeared in the October 1, 2001, issue of The Astrophysical Journal.

Taken from Coral Towers Observatory using a Skynyx 2-2 high speed camera and 15-cm Astrophysics Apochromatic Refractor at F/16 on a software bisque PME mount.
This beautiful capture of the Trifid Nebula was achieved at the Green Bank Observatory in Green Bank, WV USA. I was attending Star Quest 2022. I highly recommend this event to you for 2023 and beyond.
The Trifid Nebula is an emission nebula. It is 5,200 light years away.
This picture was captured with an Astro Physics 5" f/8 refractor, and a ZWOI294MC camera. The software was SharpCap Pro. This was a series of 30 second exposures that were "live-stacked". The only post processing that was done was some minor adjustments using Light Room Classic and PhotoShop.
This was my first color capture of a nebula.
This NASA/ESA Hubble Space Telescope observation has captured the galaxy CGCG 396-2, an unusual multi-armed galaxy merger which lies around 520 million light-years from Earth in the constellation Orion.
This observation is a gem from the Galaxy Zoo project, a citizen science project involving hundreds of thousands of volunteers from around the world who classified galaxies to help scientists solve a problem of astronomical proportions: how to sort through the vast amounts of data generated by telescopes. A public vote selected the most astronomically intriguing objects for follow-up observations with Hubble. CGCG 396-2 is one such object, imaged here by Hubble’s Advanced Camera for Surveys.

The scattered stars of the globular cluster NGC 6355 are strewn across this image from the NASA/ESA Hubble Space Telescope. NGC 6355 is a galactic globular cluster that resides in our Milky Way galaxy's inner regions. It is less than 50,000 light-years from Earth in the constellation Ophiuchus.
Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars that are associated with all types of galaxies. Their dense populations of stars and mutual gravitational attraction give these clusters a roughly spherical shape that holds a bright, central concentration of stars surrounded by an increasingly sparse sprinkling of stars. The dense, bright core of NGC 6355 shines in crystal-clear detail as Hubble is able to resolve individual stars in the crowded area toward the center of this image.

In celebration of the 31st anniversary of the launching of NASA's Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant "celebrity star," one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust.
The price for the monster star's opulence is "living on the edge." The star, called AG Carinae, is waging a tug-of-war between gravity and radiation to avoid self-destruction.
The expanding shell of gas and dust that surrounds the star is about five light-years wide, which equals the distance from here to the nearest star beyond the Sun, Proxima Centauri.
The huge structure was created from one or more giant eruptions about 10,000 years ago. The star's outer layers were blown into space – like a boiling teapot popping off its lid. The expelled material amounts to roughly 10 times our Sun's mass.

This image shows multiwavelength perspectives on the pulsar PSR B1509-58. The 2 Micron All-Sky Survey (2MASS) infrared images shows a large area of the sky around the pulsar. The SuperCOSMOS optical image is closer in and shows a surrounding cloud of gas. Chandra X-ray data show the effects of an energetic wind powered by the pulsar. The X-ray emission results from very energetic electrons spiraling in a magnetic field. Finger-like structures extend to the upper right and energize knots of material in the gas cloud. The Molonglo Observatory Synthesis Telescope (MOST) radio data shows the larger structure of the supernova remnant SNR G320.4-1.2 that encircles the pulsar PSR B1509.

Galaxy NGC 6503 is part of a large survey of more than 100 galaxies conducted by Chandra that looked for evidence of growing black holes. A new study uncovered evidence that stellar-mass black holes in these dense environments are ripping apart multiple stars, and then using their debris to fuel their growth. The Chandra results provide one pathway for the creation of "intermediate mass black holes," a class that are bigger than the stellar-mass variety but smaller than supermassive black holes. Chandra data is shown with optical images from the Hubble Space Telescope.
