A new imaging project has been published on Cosgrove's Cosmos!

Messier 106 - is a huge energetic galaxy with a supermassive black hole at its core. It is located 22-25 million light-years away in the constellation of Canes Venatici.

This is a wide-field view that shows not only Messier 106 but also a score of small little galaxies scattered across the image field!

This image is the result of 5.6 hours of LRGB integration with my Askar FRA400 Astropgraph using a ZWO ASI1600MM-Pro camera and an IOptron CEM26 mount.

During galaxy season I always have trouble selecting targets for this widefield scope. Galaxies are typically small and require a longer focal length than this scope has.

I finally settled on the region around M106, as it is filled with a group of small galaxies, and I thought the entire field might be interesting to image.

This was shot over 3 evenings on the nights of 5-29-22, 5-30-22, and 5-31-22.

I was pretty pleased with the color and detail I was able to get with such a small scope. It makes me want to go back next year and capture this with my Astro-Physics 130mm APO and its ASI2600MM-pro camera!

The story of the image and complete processing walk-through can be seen on my website at:

Using the U.S. National Science Foundation National Radio Astronomy Observatory’s (NSF NRAO) U.S. National Science Foundation Very Large Array (NSF VLA), astronomers have revealed for the first time the huge flow of gas near a massive star in the making which allows its rapid growth. By observing the young star HW2 in Cepheus A, located 2300 light years from Earth, researchers have resolved the structure and dynamics of an accretion disk feeding material to this massive star. This finding sheds light on a central question in astrophysics: how do massive stars, which often end their lives as supernovae, accumulate their immense mass?

NASA’s Solar Dynamics Observatory captured this image of Earth and the moon transiting the sun together on Sept. 13, 2015. The edge of Earth, visible near the top of the frame, appears fuzzy because Earth’s atmosphere blocks different amounts of light at different altitudes. On the left, the moon’s edge is perfectly crisp, because it has no atmosphere. This image was taken in extreme ultraviolet wavelengths of 171 angstroms. Though this light is invisible to our eyes, it is typically colorized in gold.

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 Angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance.

Capture in London, England, 2021.

December's Full Moon in the UK, also known as Cold Moon, Moon Before Yule and Wolf Moon.

This 2003 Chandra image of the supermassive black hole at our Galaxy's center, a.k.a. Sagittarius A* or Sgr A*, was made from the longest X-ray exposure of that region to date. In addition to Sgr A* more than two thousand other X-ray sources were detected in the region, making this one of the richest fields ever observed.

During the two-week observation period, Sgr A* flared up in X-ray intensity half a dozen or more times. The cause of these outbursts is not understood, but the rapidity with which they rise and fall indicates that they are occurring near the event horizon, or point of no return, around the black hole. Even during the flares the intensity of the X-ray emission from the vicinity of the black hole is relatively weak. This suggests that Sgr A*, weighing in at 3 million times the mass of the Sun, is a starved black hole, possibly because explosive events in the past have cleared much of the gas from around it.

Evidence for such explosions was revealed in the image - huge lobes of 20 million-degree Centigrade gas (the red loops in the image at approximately the 2 o'clock and 7 o'clock positions) that extend over dozens of light years on either side of the black hole. They indicate that enormous explosions occurred several times over the last ten thousand years.

Further analysis of the Sgr A* image is expected to give astronomers a much better understanding of how the supermassive black hole in the center of our galaxy grows and how it interacts with its environment. This knowledge will also help to understand the origin and evolution of even larger supermassive black holes found in the centers of other galaxies.

Approximately 404,297km from Earth. Captured in London, England, January 2021.

Taken from Coral Towers Observatory using a Skynyx 2-2 high speed camera and 16-cm Astrophysics Apochromatic Refractor at F/16 on a software bisque PME mount.

This shining disk of a spiral galaxy sits approximately 25 million light-years away from Earth in the constellation of Sculptor. Named NGC 24, the galaxy was discovered by British astronomer William Herschel in 1785, and measures some 40,000 light-years across.

This picture was taken using the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys, known as ACS for short. It shows NGC 24 in detail, highlighting the blue bursts (young stars), dark lanes (cosmic dust), and red bubbles (hydrogen gas) of material peppered throughout the galaxy’s spiral arms. Numerous distant galaxies can also been seen hovering around NGC 24’s perimeter.

However, there may be more to this picture than first meets the eye. Astronomers suspect that spiral galaxies like NGC 24 and the Milky Way are surrounded by, and contained within, extended haloes of dark matter. Dark matter is a mysterious substance that cannot be seen; instead, it reveals itself via its gravitational interactions with surrounding material. Its existence was originally proposed to explain why the outer parts of galaxies, including our own, rotate unexpectedly fast, but it is thought to also play an essential role in a galaxy’s formation and evolution. Most of NGC 24’s mass — a whopping 80 percent — is thought to be held within such a dark halo.

Geography and astrophysics team together to make it difficult to observe a sunset over water along the east coast. Cape Cod, because it juts out so far into the Atlantic, provides an opportunity to defy the norm.

This NASA/ESA Hubble Space Telescope image reveals the vibrant core of the galaxy NGC 3125. Discovered by John Herschel in 1835, NGC 3125 is a great example of a starburst galaxy — a galaxy in which unusually high numbers of new stars are forming, springing to life within intensely hot clouds of gas.

Located approximately 50 million light-years away in the constellation of Antlia (The Air Pump), NGC 3125 is similar to, but unfathomably brighter and more energetic than, one of the Magellanic Clouds. Spanning 15,000 light-years, the galaxy displays massive and violent bursts of star formation, as shown by the hot, young, and blue stars scattered throughout the galaxy’s rose-tinted core. Some of these clumps of stars are notable — one of the most extreme Wolf–Rayet star clusters in the local Universe, NGC 3125-A1, resides within NGC 3125.

Despite their appearance, the fuzzy white blobs dotted around the edge of this galaxy are not stars, but globular clusters. Found within a galaxy’s halo, globular clusters are ancient collections of hundreds of thousands of stars. They orbit around galactic centers like satellites — the Milky Way, for example, hosts over 150 of them.

Sh2-112 is a visibly emitting nebula in the constellation of Cygnus.

It is located in the northern part of the constellation, about 1.5 ° to WNW of the brilliant star Deneb.

It is a circular H II region of apparent size of about 15', crossed by a dark band on its western side oriented in a north-south direction. It is believed that the star responsible for its excitation is BD+45 3216; estimates of the distance of this star provide a value of 1740 parsec (about 5670 light years), which would place so Sh2-112 in a region of the Orion Arm particularly rich and physically very close to the great nebulous system of Cygnus X.

The Hubble constant — the rate at which the Universe is expanding — is one of the fundamental quantities describing our Universe. A group of astronomers from the H0LiCOW collaboration, led by Sherry Suyu, Max Planck professor at the Technical University Munich (TUM) and the Max Planck Institute for Astrophysics in Garching, Germany, used the NASA/ESA Hubble Space Telescope and other telescopes in space and on the ground to observe five galaxies in order to arrive at an independent measurement of the Hubble constant.

This research was presented in a series of papers to appear in the Monthly Notices of the Royal Astronomical Society.

The new measurement is completely independent of — but in excellent agreement with — other measurements of the Hubble constant in the local Universe that used Cepheid variable stars and supernovae as points of reference [heic1611].

However, the value measured by Suyu and her team, as well as those measured using Cepheids and supernovae, are different from the measurement made by the ESA Planck satellite. But there is an important distinction — Planck measured the Hubble constant for the early Universe by observing the cosmic microwave background.

On Earth, amethysts can form when gas bubbles in lava cool under the right conditions. In space, a dying star with a mass similar to the Sun is capable of producing a structure on par with the appeal of these beautiful gems.

As stars like the Sun run through their fuel, they cast off their outer layers and the core of the star shrinks. Using NASA’s Chandra X-ray Observatory, astronomers have found a bubble of ultra-hot gas at the center of one of these expiring stars, a planetary nebula in our galaxy called IC 4593. At a distance of about 7,800 light years from Earth, IC 4593 is the most distant planetary nebula yet detected with Chandra.

This new image of IC 4593 has X-rays from Chandra in purple, invoking similarities to amethysts found in geodes around the globe. The bubble detected by Chandra is from gas that has been heated to over a million degrees. These high temperatures were likely generated by material that blew away from the shrunken core of the star and crashed into gas that had previously been ejected by the star.

The galaxy NGC 1961 unfurls its gorgeous spiral arms in this newly released image from NASA’s Hubble Space Telescope. Glittering, blue regions of bright young stars dot the dusty spiral arms winding around the galaxy’s glowing center.

NGC 1961 is an intermediate spiral and an AGN, or active galactic nuclei, type of galaxy. Intermediate spirals are in between “barred” and “unbarred” spiral galaxies, meaning they don’t have a well-defined bar of stars at their centers. AGN galaxies have very bright centers that often far outshine the rest of the galaxy at certain wavelengths of light. These galaxies likely have supermassive black holes at their cores churning out bright jets and winds that shape their evolution. NGC 1961 is a fairly common type of AGN that emits low-energy-charged particles.

Located about 180 million light-years away, NGC 1961 resides in the constellation Camelopardalis.

Zeta Ophiuchi is a star with a complicated past, having likely been ejected from its birthplace by a powerful stellar explosion. A new look by NASA's Chandra X-ray Observatory helps tell more of the story of this runaway star.

Located about 440 light-years from Earth, Zeta Ophiuchi is a hot star that is 20 times more massive than the Sun. Previous observations have provided evidence that Zeta Ophiuchi was once in close orbit with another star, before being ejected at about 100,000 miles per hour when this companion was destroyed in a supernova explosion over a million years ago. Previously released infrared data from NASA's now-retired Spitzer Space Telescope, seen in this new composite image, reveals a spectacular shock wave (red and green) that was formed by matter blowing away from the star's surface and slamming into gas in its path. Data from Chandra shows a bubble of X-ray emission (blue) located around the star, produced by gas that has been heated by the effects of the shock wave to tens of millions of degrees.

A team of astronomers led by Samuel Green from the Dublin Institute for Advanced Studies in Ireland has constructed the first detailed computer models of the shock wave. They have begun testing whether the models can explain the data obtained at different wavelengths, including X-ray, optical, infrared and radio observations. All three of the different computer models predict fainter X-ray emission than observed. The bubble of X-ray emission is brightest near the star, whereas two of the three computer models predict the X-ray emission should be brighter near the shock wave.
