Interacting Galaxies NGC 1549 and NGC 1553 in the Dorado Group - From Rolf Wahl Olsen - flic.kr/p/2jybqyW

This very deep image shows the two large interacting galaxies NGC 1549 and NGC 1553 in the Dorado Group. Located around 60 million light years away towards the southern constellation Dorado, it is one of the richest galaxy groups of the Southern Hemisphere with 46 members and tens of additional candidate members.

The interaction of NGC 1549 and NGC 1553 appears to be in an early stage, and gravitational disruption in the form of irregular shells and tidal jet/arcs of material is clearly visible in both galaxies.

Between the two large galaxies a small fuzzy blob with a faint spiral structure is visible; perhaps a remnant core from an earlier interaction, similar to the one observed in the shell elliptical galaxy NGC 3923 in Hydra.

The largest of the galaxies is NGC 1549 to the North (top), discovered by John Herschel on 6 December 1835. It contains a supermassive black hole with an estimated mass between 390 and 810 million solar masses.

To the south lies NGC 1553; the second brightest member of the Dorado Group. It is an impressive lenticular galaxy with a prominent soft isophotic ring surrounding another highly structured ring encircling the centre. A further very small spiral structure is visible in the core. In 2000 an inner torus-like dust lane about 3″ across was observed by the Hubble Space Telescope at the galaxy's center. The galaxy is thought to host an obscured central active galactic nucleus (AGN).

In the lower left of the image lies the small edge-on spir...

MESSENGER View of Mercury's Caloris Basin - From Goddard Space Flight Center - flic.kr/p/aCLGkd

NASA image acquired October 28, 2011

This stunning, and as of yet unnamed, crater lies within the Caloris basin. Its floor provides another example of the beautiful "hollows" found on Mercury and has an etched appearance similar to that found in the crater Tyagaraja.

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 250-meter/pixel (820 feet/pixel) morphology base map or the 1-kilometer/pixel (0.6 miles/pixel) color base map. It is not possible to cover all of Mercury's surface at this high resolution during MESSENGER's one-year mission, but several areas of high scientific interest are generally 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, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.

67P/Churyumov-Gerasimenko - Rosetta - From Aster Cowart (terrasabaea.bsky.social) - flic.kr/p/RmwyuY

Rosetta OSIRIS-Wide Angle Camera view of Comet 67P taken during a far excursion on April 11, 2015. When this image was taken, Rosetta was located about 140 km from the comet's center, at a 90 degree phase angle, allowing the spacecraft to observe a half-lit comet.

The day side of the comet experiences intense outgassing activity, forming the bright jets of gas and dust that face sunward. The material in these jets eventually spreads out into a diffuse cloud called the coma. The presence of the coma allowed Rosetta to observe the comet's shadow.

This image uses HDR to bring out details of the comet's jets without overexposing the comet's surface. The jets are much fainter than the comet's surface, and are barely visible in a properly exposed image.

8 Micron Spitzer View of the Galactic Core - From Judy Schmidt (geckzilla.bsky.social) - flic.kr/p/2jW97dA

The same mosaics from this view except using the 8 micron data for luminosity, and the other three channels for color. This significantly reduces the starlight signal, though not totally. Still makes it much easier to see the dust and emission nebulas.

Note that much of the nebulosity is in the foreground as we view the Milky Way's center through one of the arms of the Milky Way. It is difficult to discern or even measure the distance to each piece, but generally, the larger structures that extend far away from flat central plane are foreground objects, while thinner, smaller pieces that remain close to the plane are closer to the core. Many of these smaller objects are overlapped and obscured by mid and foreground objects.

Luminosity: 8.0 µm (IRAC4)
Red: 5.8 µm (IRAC3)
Green: 4.5 µm (IRAC2)
Blue: 3.6 µm (IRAC1)

The image is presented in galactic coordinates, with north up in that regard.

A Micro Dust Cloud Superimposed on NGC 3269 - From Rolf Wahl Olsen - flic.kr/p/wDYDTE

NGC3269 is one of the most interesting galaxies in the Antlia Cluster. This appears to be an Sa spiral surrounded by several tidal loops and clumps. A particularly curious feature is a tiny 4 arcsecond wide brown dust cloud superimposed on the bright blue spiral arms.

In the image above, on the left is a 2X enlarged crop of NGC3269. At the bottom right is a close-up taken with the 6.5m Magellan Telescope which shows the micro dust cloud in detail, including two additional very small patches each about 0.5 arcseconds wide. One of these is identifiable in my image, as can be seen in the 4X enlarged crop inserted at the top.

These are suspected to be unique small foreground dust clouds of a previously unknown type. For more details on this peculiar feature see "A Tiny Galactic Dust Cloud Projected onto NGC 3269?", B. Dirsch et al. 2005 The Astronomical Journal 130 1141

The Swan Nebula - Optical/Infrared Comparison - From Rolf Wahl Olsen - flic.kr/p/fsFLfD

This image shows the bright nebula Messier 17, also known as the Swan Nebula or the Omega Nebula.
This nebula is located about 6000 light years away in the constellation of Sagittarius. It was discovered by Swiss astronomer Philippe Loys de Chéseaux in 1745 and later catalogued by Charles Messier in 1764.
The central part of the nebula is lit up by a cluster of extremely bright young O and B type stars. It is one of the brightest and most massive star forming regions in our galaxy and appears very similar in spatial structure to the famous Orion Nebula, but the Swan is viewed more edge-on from our vantage point. The nebula is also very bright visually, actually much more so than its famous neighbour the Eagle Nebula - which traditionally is the more photographed of the two.

Visible above the nebula is a pair of very unique bright orange stars. These are LBV (Luminous Blue Variable) type stars HD 168607 and HD 168625 respectively, two rare yellow hypergiants that might have formed what is known as a pseudo-photosphere. This is a theoretical optically dense surface present due to intense stellar winds and thus not the actual surface of the star. This pseudo-photosphere is much cooler than the underlying surface of the star and therefore appears yellow to us. The right-most of these two stars in the image (HD 168625) also has an associated complex nebulousity surrounding. This nebula appears very similar to the double ring structure observed around Sandulaek -69° 202 which w...

NASA's MESSENGER Satellite Captures Spectacular Color Mosaic of Mercury - From Goddard Space Flight Center - flic.kr/p/9uD599

NASA image acquired: January 14, 2008

This spectacular color mosaic shows the eastern limb of Mercury as seen by MESSENGER as the spacecraft departed the planet following the mission's first Mercury flyby in January 2008. The colors of this image are not those that would be seen by the human eye but instead convey information about the distribution of different rock types on Mercury's surface. The different rock types result in subtle color variations across all of the 11 WAC narrow-band color filters. The Caloris basin, visible as a large bright yellow circular area in this image due to its infill of volcanic plains, dominates the northern region. A similar image was published in Science magazine in July 2008, but it only covered the northern half of the region shown here. To create this larger color mosaic, MESSENGER Science Team members had to also devise a method to deal with scattered light in the 11 different WAC filters. MESSENGER has obtained color imaging at this resolution only for the portions of Mercury seen on departure from Mercury flybys 1 and 2.

As spectacular as this color image is, it is just a taste of what is yet to come. In 2011, MESSENGER will become the first spacecraft ever to orbit Mercury and begin a year-long observing campaign that includes imaging all of Mercury's surface in color at an average resolution of about 1 kilometer/pixel (0.6 miles/pixel), a resolution that is about a factor of three better than this already impressive image.

Centaurus A Extreme Deep Field - 130 Hours - Sep 2019 - From Rolf Wahl Olsen - flic.kr/p/2hk73QH

The Deepest View Ever Obtained of Centaurus A (NGC 5128)
New improved version with 10 hours of H-Alpha, Sep 2019
In 2013 I gathered 120 hours of data on Centaurus A, and processed the deepest image ever obtained of this magnificent galaxy showing many features and structures not revealed by amateurs before.
In Feb 2014 I released an improved version of the image with higher resolution, processed using PixInsight.
Then in 2018 I again acquired further data (for what is evidently a never-ending project…), this time in the H-Alpha wavelength. This new re-processed image incorporates the H-Alpha data in order to highlight the impressive emission structures triggered by the relativistic jet from the supermassive central black hole. It also emphasises the many pink hydrogen clouds in the dark dust lane across the centre of the galaxy, and lastly I feel the image showcases the concentric shells and rich background slightly better, while keeping a reasonably subtle natural look.

About the Image
This image is the realisation of a long time dream of mine: Taking a deep sky image with more than 100 hours of exposure.
I set out on this mission in early 2013 and after having gathered 130 hours of data on 46 different nights in 2013 and 2018 I present what I believe is the deepest view ever obtained of Centaurus A. This is likely also the deepest image ever taken with amateur equipment, showing stars as faint as magnitude 25.45.
I spent around 40 hours and analysing processing the data...

A super faint edge-on disk galaxy, and somewhat of an enigma. How it formed like this and how its frontal morphology might appear are subject to speculation, but chances are if we saw it from a sufficiently inclined vantage point, it would be practically invisible beyond its nucleus, assuming what we see is spread out fairly evenly along the disk and not concentrated along some very skinny arms.

Anyway, I'm happy to simply enjoy yet another wonderful variation that nature has given us.

The Distant Worlds of Uranus and Neptune - From Rolf Wahl Olsen - flic.kr/p/asv8Pf

This image shows Uranus with the four largest moons Oberon, Titania, Umbriel and Ariel - and Neptune with its large mooon Triton.
The image was taken with my 10" f/5 Serrurier truss Newtonian and is a composite of short exposures for the planet discs and longer exposures for the fainter moons. Miranda, the smallest of Uranus' five larger moons, was very close to Uranus when the image was taken and therefore lost in the glare of the planet itself in the long exposure image used to capture the moons. The orbits of the moons were added to illustrate the scale and orientation of the two systems as viewed from Earth, with South being towards the top of the image.
Both Uranus and Neptune are so far away from us that their angular diameters are only a few arcseconds, being 3.7" and 2.3" respectively. This makes it extremely difficult to discern any details on then and they nearly always appear as tiny cyan/blue balls except when imaged by large observatories or the Hubble Space Telescope. In fact, the entire orbit of Triton would easily fit behind the disc of Mars when the latter is at opposition. Still, with relatively modest equipment it is possible to get a good glimpse of these fascinating icy worlds.
