Scientists observe a red supergiant going supernova for the first time.
According to details Despite the massive number of stars in the sky, spotting one in the throes of a supernova is still an incredibly rare event.
Now, astronomers have captured a red supergiant before, during and after a supernova explosion for the first time, gathering crucial new information about these dramatic events.
“This is a breakthrough in our understanding of what massive stars do moments before they die,” said lead author Wynn Jacobson-Galán (UC Berkeley). “Direct detection of pre-supernova activity in a red supergiant star has never been observed before in an ordinary Type II supernova. For the first time, we watched a red supergiant star explode!”
