Webb directly images two planets orbiting white dwarfs

In several billion years, our sun will become a white dwarf. What will happen to Jupiter and Saturn when the sun transitions to become a stellar remnant? Life could go on, though the giant planets will likely drift further ...

JWST sees four exoplanets in a single system

When the JWST activated its penetrating infrared eyes in July 2022, it faced a massive wish-list of targets compiled by an eager international astronomy community. Distant, early galaxies, nascent planets forming in dusty ...

Even stars doomed to die as supernovae can have planets

Ninety percent of all exoplanets discovered to date (there are now more than 5,000 of them) orbit around stars the same size or smaller than our sun. Giant stars seem to lack planetary companions, and this fact has serious ...

Planet-forming disks evolve in surprisingly similar ways

A group of astronomers, led by Sierk van Terwisga from the Max Planck Institute for Astronomy, have analyzed the mass distribution of over 870 planet-forming disks in the Orion A cloud. By exploiting the statistical properties ...

Two new Saturn-mass exoplanets discovered

An international team of astronomers reports the detection of two new Saturn-mass exoplanets as part of the CARMENES radial velocity survey. The newly found alien worlds, designated TYC 2187-512-1 b and TZ Ari b, orbit nearby ...
