The exciting discovery of an extremely rare quadruple star system could significantly advance our understanding of brown dwarfs, astronomers say. These mysterious objects are too big to be considered ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

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 ...

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 ...

A team of astronomers from the University of Montreal has discovered a new potentially habitable exoplanet orbiting the red dwarf star L 98-59, 35 light-years from Earth. This discovery means there ...

It’s not easy to uncover exoplanets, largely lightless objects that either lurk in the dark void of space or are blown out by the light of a nearby star. But astronomers using the James Webb Space ...

A newly discovered interstellar comet is puzzling astronomers as it speeds through our solar system with a chemical profile unlike anything seen before. Officially named 3I/ATLAS, it's only the third ...
