Galaxies in a row
Cool image time from Hubble! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a survey of nearby “pecular” galaxies. What makes it unusual is the line of distant galaxies below the largest on the left.
The wonderful quality of this image also reveals several further galaxies, not associated with this system but fortuitously positioned in such a way that they appear to be forming a line that approaches the leftmost (in this image) component of Arp-Madore 2105-332, which is known individually as 2MASX J21080752-3314337. The rightmost galaxy, meanwhile, is known as 2MASX J21080362-3313196. These hefty names do not lend themselves to easy memorisation, but they do actually contain valuable information: they are coordinates in the right ascension and declination system used widely by astronomers to locate astronomical objects.
Both larger galaxies are thought to be about 200 million light years away, with the smaller ones far more distant. If you look at the full resolution image, you will see that there are at least six galaxies in that line, one that appears to be an elliptical galaxy with all the rest a variety of different types of spiral galaxies. The detail provided by Hubble is truly astonishing.
Though they are not linked to the larger galaxies, it is not clear if they are linked to each other.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

This could almost be an Evening Pause. Just take a moment to think about what you are looking at, the distances from us, their enormous dimensions, and how it all just happens to provide us with a beautiful image.
Thank you.
The Arp peculiar objects are some of the most interesting deep sky galaxies to observe. This is a spectacular example.
Thank you, Robert, for sharing.
