Add Yahoo as a preferred source to see more of our stories on Google. In a binary star system, two stars orbit around each other. ESO/L. Calçada, CC BY Stars are the fundamental building blocks of our ...

The discovery of the fourth star was done through an algorithm called QUADCOR, which isolates the distinct spectral fingerprints of all four stars simultaneously. By detecting the individual signals, ...

A new study by researchers at the SETI Institute suggests that stellar "space weather" could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma ...

A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...

The four-star system features three stars in stable orbits, plus a fourth at a distance equal to Jupiter's orbit around our Sun.

Astronomers already know how planetary systems are born and how they look once they ...

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 ...

Tiny interstellar visitors from other star systems are increasingly entering our solar system, with the latest, 3I/ATLAS, ...

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 ...
