Hotter than the sun: an extremely hot brown dwarf has been discovered about 1,400 light years away from us

The brown dwarf is part of a new pair system that may advance our understanding of the evolution of stars and planets under extreme radiation conditions

An international team of astronomers has announced the discovery of a second planet in the circumbinary system (where planets orbit two suns) of the rare multiple planet BEBOP-1. This planet was discovered using the transit method and was noticed because it passed in front of the brighter of the two stars on different occasions

Astronomers have discovered a pair of stars with an extremely short orbit. A star similar to our sun orbits a white dwarf every 51 minutes

The double star system AR Scorpii, located 380 light years from Earth is an unusual system. The white dwarf that shoots a concentrated beam of electrons that hits every two minutes (its spin time) its neighbor in the system - a red dwarf. Illustration: University of Warwick.

An unusual pulsar produces a focused particle accelerator-like beam that strikes its neighbor in the binary star system

Family Photo of the PH1 Planetary System: The planet you discovered is depicted in this artist's drawing as it passes in front of the larger of the two suns. In the distance, beyond the planet's orbit lies a second pair of stars gravitationally bound to the planetary system. Image: Haven Giguere/Yale.
