This artist's illustration shows a star exploding as a supernova. Astrophysicists caught the shock break out from a supernova 500 million light years away, the first indication of a massive stellar explosion. By detecting the break out, researchers were able to learn a lot about the progenitor and its surroundings. Image Credit: NASA/Swift/Skyworks Digital/Dana Berry

Astronomers were fortunate when the Einstein Probe detected the difficult-to-observe initial shock break out (SBO) from a supernova. The SBO is the first electromagnetic indication that a star is going to explode, and by observing it and the aftermath, researchers were able to determine what type of progenitor star exploded, and what it's pre-explosion environment was like.
