Their formation has been an object of debate, but new observations confirm the lead hypothesis: they are the product of incredibly bright supernovae. The rest of this article is behind a paywall.
Astronomers have for the first time observed the birth of a magnetar, a highly magnetized, rapidly spinning neutron star, directly linked to some of the universe’s brightest exploding stars. This ...
An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.
NASA just released a new image from its Webb Space Telescope of renowned supernova SN 1987A, located 168,000 light years away in the Large Magellanic Cloud. It was first discovered in February 1987, ...
A rare gravitationally lensed supernova could help astronomers determine how fast the universe is expanding and shed light on dark energy. Astronomers may be closer to understanding one of the ...
