What are neutron star collisions?

A neutron star collision is when two super-dense stars crash into each other like a really loud, really fast hug.

Imagine you have two giant marshmallows, but instead of being soft and squishy, they're hard and packed with lots of tiny, tight little marshmallow bits. These are your neutron stars. They’re so dense that a spoonful of one would weigh as much as a mountain!

Now imagine those marshmallows are zooming through space at super speed, like when you throw a ball really fast. When they finally meet, boom! It’s like two giant marshmallow rockets crashing into each other, making a huge explosion that lights up the whole neighborhood.

What happens during the crash?

When neutron stars collide, they send out waves through space, kind of like how throwing a stone into a pond makes ripples. These are called gravitational waves, and scientists can feel them all the way here on Earth, like feeling vibrations from a big earthquake!

Sometimes, this crash creates something new, like a black hole or another neutron star, depending on how much they squish together. It’s like when you smash two playdough balls, sometimes it makes one bigger ball, sometimes it makes a new shape!
