Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration depicts what the surface of one of the exoplanets orbiting Barnard's Star may look like. The other three planets ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

An international team including Cornell researcher Jake Turner has developed a novel analysis method capable of uncovering ...

A "domino effect" may occur in star systems whereby newly formed planets close to a star help shepherd dust and gas to create more planets farther out in the system. Astronomers using a mountain ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...

Astronomers have revealed new evidence that there are not just one but four tiny planets circling around Barnard's Star, the second-nearest star system to Earth. Astronomers have revealed new evidence ...

Young stars much less massive than the sun can unleash a torrent of X-ray radiation that can significantly shorten the lifetime of planet-forming disks surrounding these stars. This result comes from ...
