Fast Radio Burst predicted

Mysterious radio burst from space repeats at time astronomers predicted. "The presence of a repeating pattern could imply that the powerful bursts are linked to the orbital motion of a massive star, a neutron star or a black hole."

Solar System is Traveling through Cloud of Supernova Debris

 An international team of scientists has found interstellar iron-60, a radioactive isotope with a half-life of 2.6 million years that is predominantly produced in massive stars and ejected in supernova explosions, in deep-sea sediments dating from 33,000 years ago to the present.

Possible Local Interstellar Cloud is the remains of a supernova.
