Our magnificent gravitational wave astronomers have done it again, adding to the detection collection a new collision between two neutron stars. On 25 April 2019, the LIGO interferometer detected two neutron stars around 520 million light-years away coming together and merging into a single object.
It's called GW190425, and although it's only the second such collision astronomers have ever seen, it's already broadening our understanding of these colossal cosmic smash-ups.

BOOM!!!!! I am always curious how much energy is produced when neutron stars merge. Comparable to a supernova?

comparable to however much funding can be secured
neutron stars are a physically impossible construct and this is grant scamming huckstery

Lol. I always laugh when I see this comment. Reminds me of the lady who hit the rear quarter panel of my car and said exactly the same thing.... then she jumped into her car and fled the scene.
I texted her license plate # to my wife and she immediately called police and they caught up with her. She didn't have insurance and a valid drivers license.

Considering the vastness of space, you would think that this is a rare occurrence. Second collision? Then again, they are drawn together by gravity.

Our solar system with one star is rather rare. Binary systems or involving even more stars is much more common in the universe. Sunsets like on Tatooine are the norm.

Ah, got it. I thought this was referring to rouge systems and stars.
Apparently, Jupiter might have been our second star and make us a binary system. “If it has been more massive.”

That looks like your average run of the mill Nova!
If it said Yenko or something else it might be a Super Nova! lol

Thanks BenLurkin. Even worse is when two Oldtron stars collide, but there aren't as many of those, due to attrition.

Balderdash. The Sun accounts for 99% of the matter in our solar system. Of the remaining 1%, Jupiter is 2.5 times more massive than all the other planets combined. Jupiter would have to be 13 times more massive than it is just to be considered a brown dwarf. There was never enough matter in our solar system for Jupiter to ever become a “star” so saying “might have been” is a bit of a stretch.

It occurred before much if any life appeared on land.

A lot! It may be that most of the elements heavier than iron are produced in the mess of debris associated with the collision. Also note that when two neutron stars collide there is a very good chance the combined star will collapse into a black hole immediately.
