The Helix Nebula was the first planetary nebula discovered to contain cometary knots.Its main ring contains knots of nebulosity,which have now been detected in several nearby planetary nebulae,especially those with a molecular envelope like the Ring nebula and the Dumbbell Nebula. #nasa #universe #explore #sound #helix #nebula

Black Holes have two parts.There is the event horizon,which you can think of as the surface,though it's simply the point where the gravity gets too strong for anything to escape.And then,at the center is the singularity.That's the word we use to describe a point that is infinitely small and infinitely dense. #nasa #universe #explore #black #hole #sound
