Hello and welcome! My name is Anton and in this video, we will talk about a kilonova GRB 230307A detected by JWST that seemed to have produced a tremendous amount of different elements needed for life. But are these events dangerous for nearby planets?

Most powerful ever: https://youtu.be/4AWaqeUmQik
0:00 Neutron star collisions observed by JWST
1:10 Why this discovery is so unusual
2:10 More about this GRB and why it makes no sense
3:30 Discoveries about this explosion from JWST
4:15 Tellurium?
4:55 New mystery - why did it last so long?
5:20 Why is it outside of the galaxy?
5:50 Nucleosynthesis and formation of elements
6:20 Was this similar to how solar system formed?
7:20 What would happen to Earth if it happened near us?
8:00 How deadly do these get?
8:55 How this would affect planet Earth
9:30 Long term effects that last for 1000s of years
10:40 So still maybe unlikely to affect us any time soon
