The Butterfly Nebula, also known as NGC 6302, is a planetary nebula located in the constellation Scorpius.
It is named for its striking appearance, which resembles the wings of a butterfly when viewed in certain images.
The nebula is approximately 3,800 light-years away from Earth.

Galaxy NGC 5584
The brilliant, blue glow of young stars traces the graceful spiral arms of galaxy NGC 5584. Thin, dark dust lanes appear to be flowing from the yellowish core, where older stars reside.

this was originally meant to be a physics blog but i find myself posting more about biology related stuff - excuse my inner plant nerd but i like physics too, so:
*cough cough* SPAGHETTIFICATION! a phenomenon where you can become stretched like spaghetti if you enter a black hole.
it’s also known as the tidal effect, and is generally used to describe the vertical stretching or compression of an object into a noodle-like shape in an extremely strong and non homogenous gravitational field.
by non homogenous i just mean that the gravitational field is not the same everywhere, but consists of irregularities. (it is non-uniform)
anyways, a very common example of this is when we’re talking black holes- if i threw you into a black hole, or you happened to fall into one, the gravitational field on one end of your body would be stronger than the other.
this gravitational gradient would mean as you fell, getting closer and closer to the event horizon, your body would become extremely stretched until it would become very very compressed. like spaghetti. but don’t worry, by that time you’d already be dead.
this only happens because of the sheer strength of a black hole’s gravitational field. it’s not really because of its size - but its density. there are lots of objects close or even larger than some black holes, the mass of a black hole is so concentrated in a small area that it absolutely maximises its gravitational pull, which is why not even light can escape it.
this is just one of the relativistic effects of gravity differences, and there are so many cooler ones! for example, pancake detonation.
so stay away from black holes, or you could become stretched like spaghetti or flattened like a pancake.
