Space and Astronomy Megathread (MERGED) - Part 1

Yeah, I'd rather see a delay than have it explode. :(
 
No success today either. Imagine if sci-fi movies were anything like this...

The Orion Nebula is visible to the naked eye. It's one of the "stars" in Orion's sword:

Curious to see if this actually works. :)

The answer, as you may have heard, is yes. :pcg:

NASA Confirms DART Mission Impact Changed Asteroid’s Motion in Space | NASA

Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft's kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology.
