Pulsars to extremes: Dead spinning stars receive radio signals bursting from the ‘edges of their magnetic reach’

Two ice blue balls are shown moving towards each other.

Astronomers have discovered that rapidly spinning dead neutron stars at the heart of pulsars can emit radio signals from their edges. The finding could overturn decades of thinking that suggested pulsars only blast radiation from near their surface and at their poles. Pulsarslike everyone else neutron starsthey are created when they are big stars run … Read more

Cosmic 'Dead Zone' for Black Holes Is Real, New Evidence Suggests

The latest update to LIGO’s catalog has doubled the number of confirmed gravitational waves – waves in spacetime caused by catastrophic events. And now, astronomers come to the dire decision of selecting an updated dataset. In a Nature paper published today, researchers have confirmed the first evidence of two unstable supernovae, doing so with gravitational … Read more
