Re: APOD: Artemis 1: Flight Day 13 (2023 Nov 30)
Can someone explain why we can't see any of the MANY satellites around the Earth in these photos from space? I'd think we would almost have a ring at this time as we have so many orbiting our world. Thanks! For the same reason we don't see any stars. It's a daytime image. Stars and satellites can't...

Re: APOD: Milky Way Rising (2023 Dec 01)
If one be in outer space just outside earth in a spacesuit would the surrounding looks exactly the same as in the picture? Or is it just a long exposure that makes everything so detailed? The atmosphere only makes a tiny difference in what the sky looks like. Being in space would make only a tiny v...

APOD 1 December 2023 annotated.png Milky Way rising. Image Credit & Copyright: José Rodrigues What I find most interesting about this APOD is the gray color of the main dust lane of the Milky Way. The color is due to a magnificent sprinkling of stars in front of the dark dust lane. Many of thes...

Re: APOD: A Map of the Observable Universe (2023 Jul 05)
So the blue part over the red are full of quasars? How come they are blue instead of red? Shouldn't it be the other way around? Or is it because they are giving out so much blue light gamma, x-ray and uv light that they are more blue than the nearer galaxies?

As for the blue stars seen near the outskirts of NGC 2158, they are very, very likely outlying members of much younger (c. 175 million years old) and considerably more nearby (around 3,000 light-years) cluster M35. https://scx2.b-cdn.net/gfx/news/2020/1-openclustern.jpg M35 NGC 2158 Rolf Wahl Olsen...

What would happen if we were on the edges of that gas cloud? Would it have any effect on the solar system? It obviously would if it goes super nova.

Would there be any sunlike stars in that tail? I do see a lot of blue stars. Imagine the view if the solar system would be in that location. The galaxies would take up a big chunk of the night sky.

Re: APOD: In Ganymede's Shadow (2022 Oct 07)
Does gas giants always form in the outer colder parts of a star system or do they wander in as the time passes by? I guess it's due to gas not being able to be captured if the body is near the star?
