Saturn: July 2, 2014 - From Val Klavans (valklavans.bsky.social) - flic.kr/p/nWLXBi

This is a true color view of Saturn. Saturn's north polar hexagon stands out prominently while the rings encircle the planet.

This composite is made of images that were taken by Cassini's camera system, the Imaging Science Subsystem (ISS) on July 02, 2014 and received on Earth July 03, 2014. The camera was pointing toward SATURN at approximately 1,815,382 miles (2,921,574 kilometers) away, and the images were taken using the red, green, and blue filters.

The Cosmic Web - From Rolf Wahl Olsen - flic.kr/p/2nDaUax

The Large-Scale Structure of the Universe
Of all my images I feel that this one is the most profound: A relatively empty looking field in the southern constellation Fornax, about the size of the full Moon. This area of the sky is devoid of most bright stars, and contains almost no obscuring interstellar dust or hydrogen emission. It is therefore a window out into the deepest reaches of the observable Universe. It is also the location of the famous Hubble Ultra Deep Field and several other HST studies over the last couple of decades.
With around 60 hours of exposure the limiting magnitude is close to 25.0 which is 25 million times fainter than the dimmest naked-eye stars.

At this depth, the background is filled with tens of thousands of distant galaxies. But to see them properly, we must go on a journey - outside of our own Milky Way galaxy. To filter the many background galaxies from the foreground stars I used Gaia DR3 data to identify and remove all stars in the image, and thus revealing just the extragalactic background.
Every single point of light in the resulting image is a galaxy!
There are over 20,000 distant galaxies in this single image. With redshifts of up to z=3.354 the farthest are nearly 12 billion light years away. At that distance the field of view spans an incredible 112 x 147 million light years.
It is clearly noticeable that the galaxies are not distributed randomly. Instead, galaxy groups and clusters form long filaments with massive voids in between. ...

Above and Below Titan's Atmosphere #2 - From Val Klavans (valklavans.bsky.social) - flic.kr/p/fcxYsg

On the left is a true color image of Titan. The moon's north polar hood is visible in this view. The image on the right is a representation of what it would look like if you could see past Titan's atmosphere and down to its surface. The darker areas are vast hydrocarbon sand dunes and seas. Titan's largest sea, Kraken Mare, is visible here.

Both images were taken by Cassini's camera system, the Imaging Science Subsystem on June 26, 2013, as it was looking for clouds across Titan’s northern trailing hemisphere.

These images were taken on June 26, 2013 and received on Earth June 27, 2013. The camera was pointing toward TITAN at approximately 866,157 miles (1,393,945 kilometers) away, and the images were taken using the RED, GRN, BL1, CB3, CL1 and CL2 filters.

HH111 - From Judy Schmidt (geckzilla.bsky.social) - flic.kr/p/2hq4u9m

Took a quick break from some other work to process these lovely near-infrared observations of HH111 into a color image. The jets are well hidden from view in visible light, only just peeking out at one end. Here, many details are revealed, but the stars themselves remain veiled. Herbig-Haro objects are comprised of matter ejected rapidly from the poles of young, actively accreting stellar objects. Sometimes they are isolated puffs of cloud, but this time they are narrow, almost continuous streams. In this case it is probable that a multi-star system is forming: hubblesite.org/contents/news-releases/2000/news-2000-05.html

Total Lunar Eclipse - 26 May 2021 - From Ángel López-Sánchez - flic.kr/p/2m1PLyZ

This image combines 50 x 1" exposures, ISO 800, obtained with my CANON 5D Mark III attached at primary focus of my Skywatcher Black Diamond 80mm f600mm (F/7.5) during the Total Lunar Eclipse on Wednesday 26 May 2021, between 9:00pm and 9:04pm, Sydney local time.

The frames were manually aligned with Photoshop, then extracted as new frames to Lynkeos, that did the fine alignment. Drizzling x2 was also used. Then the combined image was taken to Photoshop, where the colour, highlights/shadows, and contrast were tuned. This got only the image of the eclipsed moon.

Additionally, I combined the full 266 x 1" images I took during totality using Siril to get the stellar background.

They two combined frames (eclipsed moon + stars) were combined with Photoshop with a bit of extra tuning to get a nice background.

The image taken at 9:03pm was used as reference for the alignment.

All the data were taken during the 4 hours ONLINE event "Conversaciones astronómicas bajo la luna eclipsada" that I organised with the "Red Andaluza de Astronomía" (RAdA), "Agrupación Astronómica de Córdoba" (AAC), "Asociación de Lengua y Cultura Española" (ALCE) de Australia and the "Spanish Researchers in Australia-Pacific" (SRAP-IEAP), that was followed by many schools in Spain.

Happy Little Crater on Mercury - From Goddard Space Flight Center - flic.kr/p/druNSE

It looks like even the craters on Mercury have heard of Bob Ross! The central peaks of this complex crater have formed in such a way that it resembles a smiling face. This image is oriented so north is toward the bottom.

This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. Visit the Why Mercury? section of this website to learn more about the key science questions that the MESSENGER mission is addressing. During the one-year primary mission, MESSENGER acquired 88,746 images and extensive other data sets. MESSENGER is now in a yearlong extended mission, during which plans call for the acquisition of more than 80,000 additional images to support MESSENGER's science goals.

Messier 46 and Planetary Nebula NGC2438 - From Rolf Wahl Olsen - flic.kr/p/dPeMLu

Messier 46 is an open star cluster located approximately 5,500 light years away in the constellation of Puppis. The cluster is around 300 million years old and contains up to 500 member stars within its diameter of 30 light years.
The cluster was discovered by Charles Messier on 19th February 1771. It is notable because of the planetary nebula NGC2438 that was discovered by John Herschel in 1833 and seems to lie within its boundaries near the bottom in this image. This is the remains of a very old star that has shedded its outer layers and become a faint white dwarf visible as the small blue point in the very centre of the nebula.
The planetary nebula has a different velocity through space than the cluster and is also closer to us at a distance of 3,000 light years, so it is not a true member of the cluster but just happens to lie in the same direction.

Hubble Explores the Hidden Dark Side of a Spiral Galaxy - From Goddard Space Flight Center - flic.kr/p/MBQuvn

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.

False Color View of Mercury - From Goddard Space Flight Center - flic.kr/p/dWW6Nt

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface.

To watch a movie of this colorful view of Mercury as a spinning globe go here: www.flickr.com/photos/gsfc/8497927473

Young crater rays, extending radially from fresh impact craters, appear light blue or white. Medium- and dark-blue areas are a geologic unit of Mercury's crust known as the "low-reflectance material", thought to be rich in a dark, opaque mineral. Tan areas are plains formed by eruption of highly fluid lavas. The giant Caloris basin is the large circular tan feature located just to the upper right of center of the image.

Deep H-alpha image of the Prawn nebula (IC 4628) in Scorpius obtained from my backyard, 15 km from Sydney’s city centre.

This image combines:

- 56 x 900s (14h) frames with the H-alpha Baader 3.5nm ultra-narrow filter (red channel and luminosity layer).
- 25 x 60s (25 min) frames with the OPTOLONG L-Pro filter (green channel)
- 14 x 30s (7 min) ZWO B filter (blue channel).

Total integration time: 14h 32 min.

The data were taken on the nights of 24th, 25th, 28th, 29th and 30th August and 7th and 12th September 2020.

Telescope: Skywatcher Black Diamond 80, f=600mm, with an Orion x0.8 focal reducer (effective focal length 480 mm, f/6).

I used the ZWO ASIAir to control the camera, filter wheel, the mount (Skywatcher AZ-EQ6) and the guiding system (ASI120MM + Orion 50mm finderscope).

Equipment: ZWO ASI1600MM Pro cooled at -30 C. I used the ZWO ASIAir to control the camera, the mount (Skywatcher AZ-EQ6) and the guiding system (ASI120MM + Orion 50mm finderscope). The filters were manually changed using the ZWO filter drawer.

The data have been processed with SIRIL, then converted into TIF using Fits Liberator using a logarithmic stretch, and finally combined in Photoshop to get the colours and the final details.

Processing: Data processed with Siril software. Darks, flats and biases were used. FITS converted on TIFF using NASA’s Fits Liberator considering a logarithmic function. Color / saturation / levels / contrast / smart sharpen with Photoshop.

Jupiter in Near-Infrared - From Judy Schmidt (geckzilla.bsky.social) - flic.kr/p/FEZA33

2018 May 06: Note that the blue channel contains data collected through a red filter, not a near-infrared one. Apologies for not mentioning that in my original description.

Why do Jupiter's poles glow brightly in infrared? I can't honestly say I know why, but I like the way it is completely opposite from visible light. In visible light, the poles are darker, and the middle latitudes near the limb practically glow in blue light. The Great Red Spot is also visible as a large, salmon hued spot in this image. Jupiter is interestingly contrasty in the near-infrared FQ889N filter, which is one of the methane bands.

These data were collected by Hubble to assist in providing context for Juno data, which are so close up to the planet that the field of view relatively small, and it can be helpful to see what is going on with the rest of the planet at the same time. A variety of data were collected for this purpose, including visible, near-uv, and near-infrared.Knowing this, one begins to gain an understanding of how having robust and overlapping datasets from various observatories and probes working in tandem can greatly augment scientific research. Juno or Hubble data alone would be much less valuable. In short, it takes a village.

I thought I would get Europa in this image, but then I found out that moon was hiding in Jupiter's shadow. Io was hanging out in the corner way out of the way, and two fainter moons could also be seen. Io was saturated anyway, and the faint moons were...

A test of the Eagle Nebula from Sydney - From Ángel López-Sánchez - flic.kr/p/2jmLyh5

This is my first test image of the Eagle Nebula (M 16) using my amateur equipment from my backyard, 15 km North from Sydney's city center, on 1st July 2020.

This image compiles 32 x 300s images (2 hours 40 minutes total integration time) obtained with my Skywatcher Black Diamond 80, an Orion X0.8 focal reducer (f/6), the ZWO ASI178MC camera and an OPTOLONG L-Pro filter.

I used the ZWO ASIAir to control the camera, the mount (Skywatcher AZ-EQ6) and the guiding system (ASI120MM + Orion 50mm finderscope).

Flats and darks included. Data processed with Siril software. Color / saturation / levels / contrast / smart sharpen with Photoshop.
