For years, scientists have suspected that stars can meet their doom by a one-two punch of back-to-back explosions — but they've never seen visual evidence of this happening. That just changed.

In an exciting new study published in Nature Astronomy, astronomers have unveiled unexpected findings from the XRISM satellite mission. The research team, led by experts from Japan and the U.S., ...
