Andromeda's Extended Clusters - From Judy Schmidt (geckzilla.bsky.social) - https://flic.kr/p/niX7Hz

Once again we are faced with objects which defy categorization. These look something like globular clusters but they're not as compact. They're kind of like dwarf galaxies, but not quite that, either. No one has found any of these extended clusters anywhere in the Milky Way, so it is thought that because only Andromeda has them that they represent clues to the differing histories of Milky Way and Andromeda.

Anyway, if you are feeling inquisitive, all of this information can be found in this paper which goes into plenty of detail about what they are and where they may have come from.

Using Stellarium, I made a picture showing where the four clusters are located. I knew they were in the outer halo of Andromeda but EC4 is surprisingly far away to me.

These data all came from this proposal:
Deep imaging of newly discovered globular clusters in the outer halo of M31

Red: ACS/WFC F814W
Green: Pseudo
Blue: ACS/WFC F606W

North is 65° clockwise for all four clusters.

Barnard's Galaxy Deep Field - 29.5 Hours - From Rolf Wahl Olsen - https://flic.kr/p/23av3gA

This image shows a deep view of Barnard's Galaxy (NGC 6822), an irregular dwarf galaxy that is one of the nearest neighbours to our Milky Way. This galaxy was discovered by astronomer Edward E. Barnard in 1884 and is located about 1.6 million light years away in the constellation Sagittarius. Despite boasting a meagre 10 million stars, and extending only one tenth the size of our Milky Way, NGC 6822 contains a full menagerie of hot red star forming HII regions, planetary nebulae, bright OB associations and dark clouds.

In 1925 the famous astronomer Edwin Hubble published his paper 'N.G.C. 6822, A Remote Stellar System' which was a detailed survey of this galaxy. Apart from describing five of its brightest HII regions Hubble also discovered 11 Cehepid variables in NGC 6822. This was one of the most important discoveries in galactic astronomy and enabled NGC 6822 to be the first galaxy beyond the Magellanic Clouds to have its distance measured and in turn greatly expanded the size of the known Universe at the time.

NGC 6822 is a challenging galaxy to photograph since it has a very low surface brightness. But still many of its brightest stars are resolved together with the various star forming regions and blue OB associations.

Also visible throughout this image is a thin veil of wispy filaments, similar to high altitude fair weather clouds. These ghostly structures are now known as galactic cirrus, or Integrated Flux Nebula (IFN). Only a few decades ago such structures ...

VY Canis Majoris Ejecta Shell - From Judy Schmidt (geckzilla.bsky.social) - https://flic.kr/p/hjFU8B

$Canis Majoris is one of those stars featured in videos seeking to give us perspective and show us just how massive stars can be. Forget Earth, this star dwarfs our Sun. Actually, forget the Sun too, because this thing dwarfs things that dwarf the Sun. Anyway, you get the point. It's ginormous as far as stars go. What you see here is the star and it surrounding nebulosity. Even though it's huge, we still only see it as the tiny bright point of light left of center from our vantage point. How's that for perspective? All stars, no matter how big, are actually pretty small. Stupid space, so big and always making everything seem so small. Space is a jerk. I'm very happy with the results for this, too. I tried something different (again) without being sure what the results would be. There is some great, high resolution data in the archive for this object but it's all taken through polarized filters. I like polarized light images, but I think they may confuse people more than the usual amount that the strange, variable colors of astronomical processing often results in. To generate an image of not-so-polarized light out of the polarized light images, I figured I could stack them into a single image and it would look about like it was taken without the polarizing filters. I reduced the diffraction spikes with masked curve adjustments. The Airy disk is apparent to the upper left of the star, but it's hard to do anything about it. Just know there aren't actually perfect concentric...$

Venus - Akatsuki - From Aster Cowart (terrasabaea.bsky.social) - https://flic.kr/p/DUVb6V

Venus as seen by Japan's Akatsuki space probe on April 25, 2016. At the time this photo was taken, Akatsuki was located approximately 50,000 km above the Venusian cloud tops.

This image was assembled using near-UV and near-IR photos to create a pseudo-true color view. My procedure for creating this image exaggerates the coloration and detail visible in the clouds, which show very little detail in the visible portion of the spectrum.

Voyager 2 wide-angle view of Jupiter (July 8, 1979) - From Ian Regan - https://flic.kr/p/2ebde9P

This was one of the last wide-angle views of Jupiter that Voyager 2 snapped, before the planet became too big to be photographed in a single frame. Jupiter appears truncated due to inconsistent and inaccurate pointing of the probe’s scan platform, which housed the camera systems.

The orange, green, and violet frames were taken early in the morning of July 8, 1979. The planet was 1.35 million miles distant. The dark, fuzzy spot is the shadow of Galilean moon Callisto.

Marsrover Perseverance Sol 904 - From Simeon Schmauß (stim3on.bsky.social) - https://flic.kr/p/2p1MdE9

After the sampling operations of conglomerates at Fall River Pass were completed, the Perseverance Rover started moving West through very Rocky terrain towards a new Science objective, called the Margin Carbonate Unit.
This area is 400m west of the rover an not yet visible from the current location. Scientists hope to learn more about the past environment on Mars from the rocks there and whether it facilitated life.
This panorama was assembled from Navcam images taken on the afternoon on Sol 904. I also added sky images from sol 889. These images were taken at a different time of day, but at the same sun elevation, so they could be combined.

Turquoise Swirls in the Black Sea - From NASA Marshall Space Flight Center - https://flic.kr/p/V9dhhs

Most summers, jewel-toned hues appear in the Black Sea. The turquoise swirls are not the brushstrokes of a painting; they indicate the presence of phytoplankton, which trace the flow of water currents and eddies.

On May 29, 2017, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured the data for this image of an ongoing phytoplankton bloom in the Black Sea. The image is a mosaic, composed from multiple satellite passes over the region.

Up and Over - From NASA Marshall Space Flight Center - https://flic.kr/p/GvJQQa

Cassini orbited in Saturn's ring plane -- around the planet's equator -- for most of 2015. This enabled a season of flybys of the planet's icy moons, but did not allow for angled views of the rings and the planet's poles, like this one. But in early 2016, the spacecraft began to increase its orbital inclination, climbing higher over the poles in preparation for the mission's final spectacular orbits in 2017.

This view looks toward the sunlit side of the rings from about 16 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on Feb. 26 2016 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 752 nanometers.

The view was obtained at a distance of approximately 1.7 million miles (2.8 million kilometers) from Saturn. Image scale is 103 miles (165 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.
