Astronomers see the signatures of a newly birthed black hole or neutron star - The Verge

For the first time ever, astronomers have directly witnessed the birth of a super dense object far outside of our galaxy — the rise of either a black hole or a collapsed star in real time. Up until now, we’ve only ever seen these objects many years after they…

  For the first time ever, astronomers have directly witnessed the birth of a super dense object far outside of our galaxy — the rise of either a black hole or a collapsed star in real time.

  This signal strongly suggests that something inside the supernova is gobbling up material, as black holes often do.

  It may be because most of the material from the blast might have fallen back into the black hole or neutron star.

  “We’ve seen isolated neutron stars, neutron stars crashing into each other, and we’ve seen material falling into black holes,” says Brown.
