Understanding these mergers helps explain binary star fates and potential progenitors of thermonuclear supernovae. The six known DAQ type white dwarfs exhibit log (C/H) > –0.5 and appear in optical ...

When galaxies collide, it's not a gentle affair, but it does take millions of years. Over this time, the two massive star ...

Scientists have begun to unravel the origin story of a cataclysmic collision between two black holes, which seem to have met ...

University of Warwick astronomers have uncovered compelling evidence that a nearby white dwarf is in fact the remnant of two stars merging — a rare stellar discovery revealed through Hubble Space ...

Citizen scientists have successfully located thousands of previously unknown pairs of “eclipsing binary” stars, NASA announced in June. The ongoing initiative helps space researchers hunt for ...

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 ...

SXS—Simulating eXtreme Spacetimes—is an ongoing scientific collaboration that has been generating simulations of dramatic events in space, particularly mergers of binary black hole systems, for ...

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 ...

Astronomers recently released a new image of the binary star system Eta Carinae's full spectrum, taken from deep in Chile's ...
