Three new planets and a mystery discovered outside our solar syste

Three planets — each orbiting its own giant, dying star — have been discovered by an international research team led by a Penn State University astronomer. Using the Hobby-Eberly Telescope, the astronomers observed the planets\’ parent stars — called HD 240237, BD +48 738, and HD 96127 — tens of light years away from our […] … learn more→

\’Darkest\’ world enlightens astronomers about mysterious light-gobbling planet

A giant Jupiter-like gas planet has been revealed to be the most light-thirsty object in the known universe — a finding that may help astronomers better understand a mysterious characteristic of similar planets found outside our solar system. Recent analysis on a planet dubbed TrES-2b has found that it probably absorbs 99.9 percent of the […] … learn more→
