These are ‘the pillars of creation’, around 7000 light years from earth. The gas and dust are in the process of creating new stars. Taken from the Hubble space telescope.
They "were" the pillars of creation. Though we can see them intact right now, we know that in reality they were destroyed by the shockwave of a nearby supernove long ago. The limit on the speed of light let's us see into the past.
How do we know they were destroyed by a supernova? Would we have to have observed the supernova to know that it happened? How could the light of the supernova arrive to tell us about the explosion before the light from the pillars?
Because by examining the star as we see it they can tell that it will go super nova soon. Therefore they predict that that star blows up and the shockwave destroys it within 7000 years of what we see. Its 7000 ly away so it's probably already gone
The shockwave from a supernova travels much much slower than the light as it is composed of matter not radiation, the light is not the shockwave. By analogy - think of all the nuclear bomb movies you've seen where there is a brilliant flast and then moments later, not simultaneously, the shock hits. Pretty much the same thing here.
There's a hypothesis that a supernova actually wiped out the Pillars of Creation, but that we won't actually see it for at least another 1,000 years.
Could stare at this for a while
Looks like it's full of people and animals..hummm
This is the second place to go on my list I'm making in elite dangerous lol always was my favorite
