Astronomers find 'gold standard' star in Milky Way

In our sun's neighborhood of the Milky Way Galaxy is a relatively bright star, and in it, astronomers have been able to identify the widest range of elements in a star beyond our solar system yet.

Ten new gravitational waves found in LIGO-Virgo's O3a data

In the last seven years, scientists at the LIGO-Virgo Collaboration (LVC) have detected 90 gravitational waves signals. Gravitational waves are perturbations in the fabric of spacetime that race outwards from cataclysmic ...

Astrophysicists theorize a new type of neutron star

A pair of researchers, one with Manly Astrophysics, the other with Universidad de Murcia, has proposed the existence of a new type of neutron star. In their paper published in the journal Physical Review Letters, Arthur Suvorov ...

Gravitational wave

In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from the source. Predicted by Einstein's theory of general relativity, the waves transport energy known as gravitational radiation. Sources of gravitational waves include binary star systems composed of white dwarfs, neutron stars, or black holes.

Although gravitational radiation has not yet been directly detected, it has been indirectly shown to exist. This was the basis for the 1993 Nobel Prize in Physics, awarded for measurements of the Hulse-Taylor binary system. Various gravitational wave detectors exist.
