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.
Messier 16, also known as the Eagle Nebula, is a famous region of the sky often referred to as the “Pillars of Creation.” The Webb image shows the dark columns of gas and dust shrouding the few remaining fledgling stars just being formed. The Chandra sources, which look like dots, are young stars that give off copious amounts of X-rays. (X-ray: red, blue; infrared: red, green, blue)

The celestial poetry is enchanting enough to alleviate even despair, so stargazing is priceless as a remedy. This is a shot of the north-northwesternmost part of the sky above Varlaam abbey in Meteora, Greece, with both Ursae constellations: Ursa Major (its 7 brightest stars, aka Big Dipper, Great Bear or The Plough) and Ursa Minor (aka Little Dipper, including the Polaris, of course).
Meteora is the name of the group comprising many impressive and lofty rock formations: The height of the sandstone megaliths ranges between 1,000-2,067 ft (300-630 m). The rock masses which were formed 60 million years ago are geologically unique and listed in UNESCO world heritage sites. The Varlaam monastery (abbey) was built in 1517-1518 on a 1,808 ft high (551 m) rock.
Astronomical details about each and every star of these constellations in comments. There is another shot with the stars’ names labeled and another without any marking lines at all.
Really beautiful object catalogued as 881 on the Lynds' Catalogue of Dark Nebulae.
It's one of the jewels that you could find on gamma Cygni nebula, on SADR region of Cygnus, one of my favorites regions of the sky.
"A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds." (wiki)
It was necessary to integrate more than 70 hours to show all faint and nice details on the estructure.

Cosmic rays and the chemicals and atoms that make up the interstellar space between stars are the focus of this year’s NASA Antarctica Long Duration Balloon Flight Campaign, which kicked into high gear with the launch of the Boron And Carbon Cosmic rays in the Upper Stratosphere (BACCUS) payload Nov. 28.
The University of Maryland’s BACCUS mission is the first of three payloads taking flight from a balloon launch site on Antarctica’s Ross Ice Shelf near McMurdo Station with support from the National Science Foundation’s United States Antarctic Program.

This Hubble image shows NGC 4789A, a dwarf irregular galaxy in the constellation of Coma Berenices. It certainly lives up to its name — the stars that call this galaxy home are smeared out across the sky in an apparently disorderly and irregular jumble, giving NGC 4789A a far more subtle and abstract appearance than its glitzy spiral and elliptical cousins.
These stars may look as if they have been randomly sprinkled on the sky, but they are all held together by gravity. The colors in this image have been deliberately exaggerated to emphasize the mix of blue and red stars. The blue stars are bright, hot and massive stars that have formed relatively recently, whereas the red stars are much older. The presence of both tells us that stars have been forming in this galaxy throughout its history.
At a distance of just over 14 million light-years away NGC 4789A is relatively close to us, allowing us to see many of the individual stars within its bounds. This image also reveals numerous other galaxies, far more distant, that appear as fuzzy shapes spread across the image.

In the summer of 2022, NASA's James Webb Space Telescope released images from some of its earliest observations with the newly commissioned telescope. Almost instantaneously, these stunning images landed everywhere from the front pages of news outlets to larger-than-life displays in Times Square.
Webb, however, will not pursue its exploration of the universe on its own. It is designed to work in concert with NASA's many other telescopes as well as facilities both in space and on the ground. These new versions of Webb’s first images combine its infrared data with X-rays collected by NASA’s Chandra X-ray Observatory, underscoring how the power of any of these telescopes is only enhanced when joined with others.
The four galaxies within Stephan’s Quintet are undergoing an intricate dance choreographed by gravity. (The fifth galaxy, on the left, is an interloping galaxy at a different distance.) The Webb image (red, orange, yellow, green, blue) of this object features never-seen-before details of the results of these interactions, including sweeping tails of gas and bursts of star formation. The Chandra data (light blue) of this system has uncovered a shock wave that heats gas to tens of millions of degrees, as one of the galaxies passes through the others at speeds of around 2 million miles per hour. This new composite also includes infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue).

Over 150 globular star clusters populate the Milky Way Galaxy. Many formed early in the evolution of the galaxy and are distributed in a roughly spheroidal halo extending above and below the galactic plane. The four clusters in this composite image were captured with the same telescope and camera under similar conditions and are identically scaled, allowing us to see how they compare as viewed from earth. Each photo spans just under 0.5 degrees on a side, or about the width of the full moon.

The Great Nebula in Orion (M42) and the Running Man Nebula (NGC 1977).
The Orion Nebula (Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way Galaxy, south of Orion's Belt in the constellation of Orion. M42 is located 1344 light-years away, and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light-years across. It has a mass of about 2000 times the mass of the Sun.
About this image:
This is really a "work in progress" test image, and is compiled from a combination of "One Shot Color" (OSC) DSLR RGB image data, and Hydrogen-Alpha (Ha), Oxygen III (OIII), and Sulphur II (SII) Narrowband image data (collected at several Star Parties and Astronomy weekends in the past year).
Even though the Orion Nebula is probably the first Deep Sky Object that every Astrophotographer images, it is actually a tricky nebula to photograph and process due to its wide high dynamic range of bright and faint nebulosity.

Iteration on the Sharpless catalogue of faint nebulae.
It's not a common object, and here is the close up. Very faint and difficult. I am really proud of it :D
Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.
The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.
This nebula is about 2/3 the diameter of the full moon.

It was a cloud day at Alpha Ridge Park in Marriottsville, MD USA as I prepared for the start of Howard County Recreation and Parks Solar Fest event. In the view is the Howard Astronomical League observatory. In front is my AstroPhysics 105mm refractor telescope with a Herschel Prism on the back-end to allow for safe solar viewing. Although the skies did not cooperate for a great day of viewing the sun, this picture came out very nicely. It was captured with my iPhone 14 and enhanced in Adobe Lightroom Classic.

Description from NASA APOD:
Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. This sharp, colorful image reveals the galaxy's bulging central core cut by obscuring dust lanes that lace NGC 4565's thin galactic plane. An assortment of other background galaxies is included in the pretty field of view, with neighboring galaxy NGC 4562 at the upper left. NGC 4565 itself lies about 40 million light-years distant and spans some 100,000 light-years. Easily spotted with small telescopes, sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed.

In this 2008 X-ray image, the giant elliptical galaxy M87 reveals evidence for a series of outbursts from the central supermassive black hole. The loops and bubbles in the hot, X-ray emitting gas are relics of small outbursts from close to the black hole. Other interesting features in M87 are narrow filaments of X-ray emission, which may be due to hot gas trapped by magnetic fields. One of these filaments is over 100,000 light years long, and extends below and to the right of the center of M87 in almost a straight line.

Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA’s Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior may explain a remarkable torrent of star formation occurring in a distant cluster of galaxies.
Galaxy clusters contain hundreds or thousands of galaxies pervaded by hot, X-ray emitting gas that outweighs the combined mass of all the galaxies. Ejections of material powered by a supermassive black hole in the cluster’s central galaxy usually prevent this hot gas from cooling to form vast numbers of stars. This heating allows supermassive black holes to influence or control the activity and evolution of their host cluster.
But what happens if that black hole stops being active? The galaxy cluster SpARCS104922.6+564032.5 (SpARCS1049 for short) located 9.9 billion light years away from Earth is supplying one answer.
Based on observations from NASA’s Hubble Space Telescope and Spitzer Space Telescope, astronomers had previously discovered stars were forming at an extraordinary rate of about 900 new Suns worth of mass per year in SpARCS1049. This is over 300 times faster than the rate at which our galaxy, the Milky Way, is forming its stars. (At the rate seen in SpARCS1049, all of the stars in the Milky Way could form in just 100 million years, which is a short period of time compared to our Galaxy’s age of more than ten billion years.)

NASA and the National Park Service worked together to create a web-based tool that helps park managers better understand the impact of outdoor lighting and noise on animal species in national parks.
The website allows park managers to choose a time period, such as the spring or winter seasons, and then zoom into a particular park to see sound and nighttime lights data and determine which animal species might be at risk from those sensory stimuli.
Observations from space, such as nighttime light data from the NASA/NOAA Suomi NPP satellite used to produce this United States map, help to better gauge the impact of outdoor lighting on animal species in national parks.
April 16-24, 2022, 2022, is National Park Week. Parks across the country are hosting events virtually and in-person.

About this image:
A HaRGB widefield mosaic of the North America Nebula (NGC 7000 or Caldwell 20) and Pelican Nebula (IC 5070 and IC 5067), emission nebulae in the constellation Cygnus (close to Deneb, a Blue-White Hot Supergiant star).
The shape of the North America Nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. With a bit of imagination the Pelican's profile is also clearly visible at the bottom right of this image.
About Star Colors:
You will notice that star colors differ from red, orange and yellow, to blue. This is an indication of the temperature of the star's Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red ones are cooler.

In the center of this galaxy is a supermassive black hole feeding off the gas and dust encircling it, and large jets of high-energy particles and other material spewing out. The jet shown at the upper left of this image extends for about 13,000 light-years away from the black hole. Also visible is a dust lane, wrapping around the middle of the galaxy, which may have resulted from a collision with a smaller galaxy millions of years ago.
Colors in this image have been chosen to reflect the sources of data. Blue shows X-ray light captured by NASA’s Chandra X-ray Observatory, orange represents X-rays detected by NASA’s Imaging X-ray Polarimetry Explorer (IXPE) satellite, and optical light seen by the European Southern Observatory in Chile is colored white and gray.
Cen A has been studied extensively since the launch of Chandra in 1999. With IXPE, which launched in 2021, scientists can understand the mysteries of this object in a new way. IXPE is specialized to look at a property of X-ray light called polarization, which relates to the organization of electromagnetic waves. This specialized measurement is helping scientists study how particles become accelerated to high energies and speeds — nearly the speed of light — at extreme cosmic objects like this one.
At Cen A, researchers using IXPE seek to understand what causes the X-ray emission in the jets. So far, scientists have not detected X-ray polarization at Cen A, indicating that particles much heavier than electrons, such as protons, are not producing the X-rays. More insights are to come as scientists analyze the data.
Cen A is found 12 million light-years from Earth in the constellation Centaurus and represents the fifth brightest galaxy in the sky.

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.
Messier 74 is also a spiral galaxy — like our Milky Way — that we see face-on from our vantage point on Earth. It is about 32 million light-years away. Messier 74 is nicknamed the Phantom Galaxy because it is relatively dim, making it harder to spot with small telescopes than other galaxies in Charles Messier’s famous catalog from the 18th century. Webb outlines gas and dust in the infrared while Chandra data spotlights high-energy activity from stars at X-ray wavelengths. Hubble optical data showcases additional stars and dust along the dust lanes. (X-ray: purple; optical: orange, cyan, blue, infrared: green, yellow, red, magenta)

This cloudy, turbulent scene acquired by the Hubble Space Telescope in 2017 shows a stellar nursery within the Large Magellanic Cloud. This nursery, known as N159, contains many hot young stars. These stars emit intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which carve out ridges, arcs, and filaments from the surrounding material. N159 is located over 160,000 light-years away, just south of the Tarantula Nebula.
At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star formation.
