If any giant planets orbited Eta Cassiopeiae A within about 8 AU, astronomers could spot their telltale signature in the spectrum of light from the star. And since no planets at all can survive the ...

NASA’s James Webb Space Telescope has shown us images of space we’d never see otherwise, and one of the latest wonders it has ...

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 ...

The binary star system NGC 3603-A1 is one of the most massive binaries ever discovered in the Milky Way Galaxy. FLAGSTAFF, Ariz., Aug. 22, 2025 /PRNewswire/ -- A team of astronomers led by Dr. Phil ...

This illustration depicts a binary star system consisting of a dense neutron star and a normal Sun-like star (upper left). Using data from the European Space Agency's Gaia mission, astronomers found ...

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 ...

The supermassive black hole at the center of our Milky Way galaxy is associated with wanton destruction, but a recent discovery throws that assumption into question. A team of international ...

Only 16 to 84 other examples of this exotic system may exist in our entire galaxy. Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner.

For astronomers, finding a new black hole orbiting an aged red dwarf star is an exciting find in itself, but when that black hole seems to be a "missing link" stellar-mass black hole, you can crank ...
