An international team of astronomers reports the discovery of a new pre-main-sequence eclipsing binary system. The newfound ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

A pair of stars orbiting one another has been found near the supermassive black hole Sagittarius A* using the European ...

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 ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have ...

The Hubble Space Telescope of the National Aeronautics and Space Administration (NASA) recently published a study in the journal Nature Astronomy, where astronomers discovered an unusual white dwarf ...

(THE CONVERSATION) Scientists first detected ripples in space known as gravitational waves from the merger of two black holes in September 2015. This discovery marked the culmination of a 100-year ...

Artist's impression of a red dwarf (left) and a white dwarf (center) orbiting each other. The stars’ orbit is so tight that their magnetic fields interact, causing pulses of radio emission every two ...

Astronomers discovered a rare ultra-massive white dwarf forged in a stellar smash-up and unmasked only by Hubble’s ...
