Starship Asterisk*

One tiny thing that I find interesting is that there appear to be three smilar-sized supernova remnants to the left of Sagittarius A*, and two much larger and therefore older supernova remnants to the right of it. I assume that the sites of star formation near Sgr A* has shifted over time. Usually,...

The "blurrier" the picture is, the harder it is to tell the difference between stars and galaxies. In today's APOD there are no long spikes emanating from the stars, which makes it even harder to tell them from elliptical or face-on spiral galaxies. Instead of spikes, there is a multitude...

Sorry if I've already asked this in the past. Whenever I look at such photos, I always wonder, which one of the bright objects (of various sizes, shapes and colors) we see are stars and which ones are galaxies. There are some photos wherein every object (almost every) is a galaxy. But, some have a ...

Where exactly is Sag A* (our galaxy's supermassive BH) in this image? An X marks the spot overlay would be very helpful, along with a dashed line showing the Milky Way's mid plain.

Not a word about the odd hexagonal highlighted object? Good question... Normally, these patterns exist only at the poles of the planets. However, I think that it is unlikely that the hexagon surrounded by the red is the former pole territory... https://instagram.fzrh3-1.fna.fbcdn.net/vp/efac3daa81e...

ThanX Ann Interesting point. But where are the wildebeests on Ceres ?-) Okey, with -106 degrees, it is a little cold. But where does the heat come from to make the soda-carbonate liquid? Maybe it was different there earlier. So I'm sure, we will find a couple of wildebeest bones on the next expediti...

Interesting picture. But I think it would be more helpful to display the effective height without image distortion, although this is less impressive... https://instagram.fzrh3-1.fna.fbcdn.net/vp/670aab987c340468e8bae753492ad397/5D8A06F4/t51.2885-15/e35/61797130_414675746041477_4065973005361516956_n....

Interesting duo ... Does anyone have a good idea what the bubbles could be in NGC 4676A? Are these stars in the foreground or are they part of the Galaxy? Jack from the AVAO team Thanks for the closeups, Jack! An interesting aspect of the blue-green "bubbles" in NGC 4676A is that they don...

Oh. ThanX 4 your interest. I'm just an amateur, but a big, big APOD fan!
The pictures for my insta account I produce myself.
For my composite images I normaly use NASA and ESA sources.

Interesting. The bright sources in this picture look like magnets in the sky, surrounded by funny-looking field lines. Well, I guess that many of them are magnets, so to speak, such as highly magnetized pulsars or maybe magnetars. Some of the "field lines" are funny-looking indeed. Severa...

I think, one of the most interesting Herbig-Haro objects in IDN1251 is HH149. The brightest star, in the picture above right (Close up/ 2nd picture), is probably a double star system. (As far as this can be judged by the Hubble picture resolution)... https://instagram.fzrh3-1.fna.fbcdn.net/vp/758146...

What a great composite picture! But what is the blue oval-shaped ring in the left upper half of the picture? Hydrogen, oxygen, or sulfur? Generally Blue... is Oxygen in this type image...Sulfur is Yellow, and Hydrogen is Red... I don't know if that changes with the Broadband RGB blended though... :...

May be it's helpful to take a closer look to the inner ring...

Ring, Bar? Where exactly? ..."Note in the NASA/ESA/Hubble picture at left that there are many hot and blue stars in the inner ring. As you can see, the dusty bar, running from the outer to the inner ring of M95, is also quite obvious. But please note in today's APOD that one half of this bar i...
