Astronomers have found supermassive black holes in smaller galaxies are actually more likely to light up when they’re isolated in vast, cosmic voids.
How Soon Will Betelgeuse Blow?
A new study making the rounds predicts that supergiant Betelgeuse will explode as a supernova sooner rather than later, but others are urging caution.
James Webb Space Telescope Uncovers Hundreds of Galaxies in Early Universe
