Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner. Pulsars are spinning neutron stars that emit twin beams of radio waves from their ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...

For the first time, astronomers have spotted a rapidly spinning neutron star that is gravitationally bound to a helium star companion. The discovery of this unusual binary system helps confirm a long ...

A large team of astronomers and astrophysicists affiliated with several institutions in China has discovered a binary star system, where one of the stars is a millisecond pulsar and the other is made ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

A research team has used both archival Hubble Space Telescope data and new observations to precisely measure the binary star system NGC3603-A1. One star weighs about 93 times the mass of our sun, ...

The binary star system NGC 3603-A1 is one of the most massive binaries ever discovered in the Milky Way Galaxy. NGC 3603-A1 is located in a dazzling cluster of stars known as NGC 3603, located some 25 ...

Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or “hot Jupiters,” astronomers can spend months or years ...
