Is the moon orbiting the Sun?

Alpha Centauri A and B
"The closest star system to the Earth is the famous Alpha Centauri group. Located in the constellation of Centaurus (The Centaur), at a distance of 4.3 light-years, this system is made up of the binary formed by the stars Alpha Centauri A and Alpha Centauri B, plus the faint red dwarf Alpha Centauri C, also known as Proxima Centauri."

The Hubble/ESA site also has a special weekly feature called "Picture of the Week", here is the link:

Oh man! you have no idea how much I miss visiting this site, long story but "I shall return".
in the mean time here is an APOD worth pondering.

An oldie but goldie...
"Color mosaic of Olympus Mons volcano on Mars from the Viking 1 Orbiter. The mosaic was created using images from orbit 735 taken 22 June 1978. Olympus Mons is about 600 km in diameter and the summit caldera is 24 km above the surrounding plains. The complex aureole terrain is visible at the top of the frame. North is up."

This 4K stuff really pushes my video to the limit but it's so awesome I play it anyway.

The Mice presage what may happen to our own Milky Way several billion years from now when it collides with our nearest large neighbor, the Andromeda Galaxy (M31).

I love the collision simulation videos, this is probably my favorite.

This is a good one of the Andromeda vs. Milky way mash up.


Weird how I posted the first video like it was a part of your message I was replying to.

you just didn't quite get your quotes in the right place

You would think I'd quit doing that by now.

Ok, today I have a very special one for us...

GN-z11, the (currently) most distant and oldest object we have seen:

This surprisingly bright infant galaxy, named GN-z11, is seen as it was 13.4 billion years in the past, just 400 million years after the Big Bang. GN-z11 is located in the direction of the constellation of Ursa Major.
[...]
Before astronomers determined the distance for GN-z11, the most distant galaxy measured spectroscopically had a redshift of 8.68 (13.2 billion years in the past). Now, the team has confirmed GN-z11 to be at a redshift of 11.1, nearly 200 million years closer to the Big Bang.
[...]
The combination of Hubble’s and Spitzer’s imaging reveals that GN-z11 is 25 times smaller than the Milky Way and has just one percent of our galaxy’s mass in stars. However, the newborn GN-z11 is growing fast, forming stars at a rate about 20 times greater than our galaxy does today. This makes an extremely remote galaxy bright enough for astronomers to find and perform detailed observations with both Hubble and Spitzer.

Great post. I can't wait for JWST to come on line, it will be interesting to see how far the next generation telescopes can push the limits beyond what the current systems are doing.

Thanks, and I agree with you completely!

Speaking of JWST,

And a very cool video as a bonus.

One of my favorites also. I downloaded a 6000 x 2906 pixel image quite some time ago.

Coincidentally, about the same time you posted those images, I was watching a video about Eta Carinae.
Fun, fascinating, and informative:

This seems appropriate as we pass another Solstice, a lot of work went into this clip, I really enjoyed the perspective it gives.

A "beautiful" megamaser, compliments of Hubble.

 

[1oldman2]

I always thought I understood Lunar phases, these clips changed that thought, very cool.

A break in the clouds this past weekend; even though seeing was poor I could get decent images of the Orion nebula by stopping down my 400/2.8 to f/4:

Edit: better non uniformity correction...
