[NEWS] Five links about Barnard’s Star b (#barnardb)

Today’s announcement of the discovery of Barnard’s Star b, a super-Earth orbiting the nearby red dwarf of Barnard’s Star a mere six light-years away from the Earth, is exciting. Not only is this one of the closest exoplanets to our own solar system, this is exciting news about the Barnard’s Star system, finally finding an actual exoplanet decades after the mistaken identification of exoplanets here.

M. Kornmesser’s artistic impression of this world in orbit around its star is lovely.

 

  • The official European Southern Observatory announcement of the discovery of a super-Earth orbiting Barnard’s Star is exciting news!
  • Centauri Dreams picks up the exciting news about Barnard b, as does Bruce Dorminey.
  • D-Brief has an extended look into the background of the astronomical project responsible for determining the near-certainty of the existence of Barnard b.
  • D-Brief notes that, unfortunately, Barnard b orbits too far from its parent red dwarf star to support anything like Earth-like conditions, to say nothing of the risk to life from occasional massive stellar flares.
