Black holes rule!
This pretty much rules also.
This is a worthwhile use of hard drive space, hours of fun. (you won't be disappointed). I recommend beginning with a tour of "Universal Beauty" in honor of this thread)
The home site https://aas.org/ is also highly recommended if you don't already use it.
Captured in one of NASA's observatory in 2016. It is 20,000 light years away.
This is called the Art of Science.
Not literally. But this is very beautiful. Majestic.
can you please give a link to the origin of that image ( a good thing to always do)
I would like to identify it
this is the link of the website the image was taken from
Deep Star Maps
Visualizations by Ernie Wright Released on January 17, 2012
(from NASA/Goddard Space Flight Center Scientific Visualization Studio)
"This set of star maps was created by plotting the position, brightness, and color of just over 100 million stars from the Bright Star, Tycho-2, and UCAC3 star catalogs. The constellation boundaries are those established by the International Astronomical Union in 1930. The constellation figures also come from the IAU, although they're not official."

From today's APOD - Where Your Elements Came From
What a good diagram! Where did you find it?
My mistake. It should have said APOD (Astronomy Picture of the Day). Just click the link in the original post.
A very cool periodic table!
Thank you for sharing that. I was trying to come up with a list of my own for a presentation, but this is super clear.
This artist’s illustration represents the scientific capabilities of NASA’s James Webb Space Telescope. Both imaging and spectroscopy will be central to the Webb mission.

I'm goofing off too much. My first thought at seeing that was Settlers of Catan.
The Pleiades are coming into view (for me) now. it also warmed up a bit, so being outside wasn't totally unpleasant:
A cropped and de-scaled version of the original [2h 20m total integration time, 400/4 (to get the 'sunstars') ISO 800].
"American Scientist" recently had an impressive photo essay (via Cassini) of Saturn's rings:

After a long winter's nap, the weather is becoming more conducive for astrophotography here in cleve-o. Last night I got this image of the Flame and Horsehead nebulae in Orion:
Total acquisition time: 2 hours with my 400/2.8 wide-open. Single frame info: 10 s, ISO 800. Not bad for urban viewing conditions!
2h total acquisition time @ 400/2.8, ISO 800... this is definitely one of the trickier ones.
