Talking about bats. Don't go too near the Bat Nebula, with its massive stars system. Or you have as Kathryn Janeway in a Star Trek Voyager episode to "batten down the hatches", when they come too close to a double neutron star system (https://www.youtube.com/watch?v=CeHtOxJMgDk).
Art, if the galaxy has a diameter of, say, 70,000 light-years, and since you have the Ghost of Jupiter to compare it with, can you estimate how big it is in our skies and how far away it must be? The bright part of NGC 3242 is about 7,000 times as far away as it is wide. Your galaxy is about 14,000...
Aah! Ooh! I love this picture with the all the red sprites :D 8-) :D I wish I would have the opportunity to see these red sprites. A very interesting phenomena. I suppose they are very hard to see from a city, because a) you need a camera (due to the short-lived phenomena) and b) the city lights sva...

I just have to comment on the fact that there have been 99999 posts commenting on The Astronomy Picture of the Day. And I guess I just made the 100,000th post.
What's cooking in the northern part of the Atlantic? Is it all the males who are starting to barberque after all the fires are gone in the northern Europe? With the smoke starting to collect out in the sea of the Atlantic?
With such a pack of black holes, there should exist hyper-velocity black holes thrown out of the center by the massive Sgr A*. With perhaps a lot of luck one should even find a hypervelocity binary including a black hole. Or have researchers already found one? Just as research show it is possible fo...
Amateur astronomer captures rare first light from massive exploding star http://news.berkeley.edu/2018/02/21/amateur-astronomer-captures-rare-first-light-from-massive-exploding-star/ University of California, Berkeley | February 21, 2018 Thanks to lucky snapshots taken by an amateur astronomer in A...
A truly marvellous thing to happen. And a big congratulation to all the pro's :-D :clap: , who co-operated on all the observations while keeping it secret until last week [though there has been some rumours since late August]. Speaking of dots connecting to make a picture (like the constellation Cas...
I like today's apod very much. If there were no Perseids I would call the picture From North America to the Center of the Milky Way . As the Milky Way starts around the North America Nebula and ends around Sagittarius and Scorpius.
Wow! What a great suggestive picture of earth and sky. First I noticed the hoodo as mentionend, and then the Milky Way. After that I see the leaning stone in the lower right and at last the light left of the stone. No one is parallell to the earlier one, but the first and the last is parallell to ea...
I just enjoy todays comments. They are so dead-pan witty.
The comparison you make, with two other of Saturn's moons is very interesting: Atlas and Iapetus. I am also looking forward to better images of Atlas. Perhaps the Cassini team will deliver something in the future.
A very well done image of Centaurus A and its surroundings. The mention of dust in the last sentence was the first thing I noticed. I fact I noticed the dust before reading the text. Thus I went to Fabian Neyer's original posting of this image. And I found an inverted image http://www.starpointing.c...
A bridge of stars connects two dwarf galaxies The Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years, according to an international team of astronomers led by researchers from the University of Cambridge. T...
The rays coming from the bright stars differ between separate parts of the image. The bright stars to the two thirds left have have rays going exactly horizontal and vertical ray. While the bright stars to the extreme right have rays slanting about 30 degrees to the rest. How could it differ so much...
As very few planetary nebulae has a square-ish tendency one might say that it is hip to be square amongst these objects. Or just take a listen to http://www.youtube.com/watch?v=LB5YkmjalDg with Huey Lewis And The News playing their song Hip To Be Square.
Also a slightly illusory picture as the ship in the front is pointing left, toward the big ship on the sky: the constellation Argo Navis with Canopus. Nowadays you don't talk about Argo Navis as it is so big and one instead speak about the constellations Carina, Vela and Puppis.
