To Kilonova
Update: 2017-11-01
Description
If two neutron stars collide in a galaxy 130 million light years away and no one has a gravitational wave observatory to detect it, does it make a sound? Well, that's a silly question, but it happened, and not only was this cosmic catastrophe observed in the high energy light it emitted, but the rippling of spacetime was detected as well. Astronomy now has two independent ways of observing energetic events, and for the first time, something was seen using both techniques: electromagnetic waves (light) and gravitational waves. Join the astroquarks to hear about the first "kilonova" observed this way and what it has to do with your gold jewelry.
