Dying stars' cocoons could be new source of gravitational waves

So far, astrophysicists have only detected gravitational waves from binary systems—the mergers of either two black holes, two neutron stars or one of each. Although astrophysicists theoretically should be able to detect ...

NASA looks back at 50 years of gamma-ray burst science

Fifty years ago, on June 1, 1973, astronomers around the world were introduced to a powerful and perplexing new phenomenon called GRBs (gamma-ray bursts). Today sensors on orbiting satellites like NASA's Swift and Fermi missions ...

Software offers new way to listen for signals from the stars

The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), led by Akshay Suresh, Cornell doctoral candidate in astronomy, is pioneering a search for periodic signals emanating from the core of our galaxy, ...

A strange quark matter core likely exists in neutron stars

At the end of a star's life, nuclear fusion ceases, and the resulting pressure is no longer sufficient to counteract the gravitational force. This collapse can lead to the formation of neutron stars, which are composed of ...
