Chandra observations reveal extraordinary magnetar

In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA's Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning ...

Stellar collision triggers supernova explosion

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from ...

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, ...

First candidate for an extragalactic planet identified

A team of researchers from the U.S. and China has found the first evidence for a candidate planet in another galaxy. In their paper uploaded to the arXiv preprint server, the team describes their work studying the possible ...

Gravitational waves will settle cosmic conundrum

Measurements of gravitational waves from approximately 50 binary neutron stars over the next decade will definitively resolve an intense debate about how quickly our universe is expanding, according to findings from an international ...

How massive can neutron stars be?

Astrophysicists at Goethe University Frankfurt set a new limit for the maximum mass of neutron stars: They cannot exceed 2.16 solar masses.

Neutron star jets shoot down theory

Astronomers have detected radio jets emitted by a neutron star with a strong magnetic field—something not predicted by current theory, according to a new study published in Nature today.
