Faintest planet ever imaged from Earth found after more than 10 years of hide-and-seek
A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the lightest exoplanets ever imaged from the ground. After spotting the planet using the European Southern Observatory's Very Large Telescope (ESO's VLT), the team found it had been hiding in archival observations spanning more than a decade.
