Stargazing
Scientists finally found the cosmic wreckage of a famous supernova that detonated 32 years ago.
The remains — from a neutron star that collapsed on itself after exploding — was hidden away in a thick cloud of space dust that Cardiff University astronomers only just pierced with the extremely sensitive ALMA telescope in Chile, according to research published Tuesday in The Astrophysical Journal. Now that it’s been spotted, scientists can better understand the process of how stars live and die.
Missing Piece
This particular supernova was closer to Earth than any other in recent centuries — the months-long explosion helped scientists understand the life cycle of stars. Now that astronomers found the aftermath, they can put more of the pieces together.
“Our new findings will now enable astronomers to better understand how massive stars end their lives, leaving behind these extremely dense neutron stars,” said study author and Cardiff astronomer Mikako Matsuura.
