The search for habitable planets has taken a leap forward with new space telescopes probing exoplanet atmospheres for life.

Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.

New findings from the ALMA telescope have revealed that planets are born in much smaller protoplanetary disks than ...
