Young exoplanet set to become Jupiter 2.0: Report

The new planet, called 51 Eridani b, is the first exoplanet discovered by the Gemini Planet Imager, a new instrument operated by an international collaboration headed by Bruce Macintosh, professor of physics at Stanford University.

To detect planets, NASA's Kepler sees their shadow. The Gemini Planet Imager instead sees their glow, which we refer to as direct imaging," said Macintosh, member of the Kavli Institute for Particle Astrophysics and Cosmology.

51 Eridani b is one of the best stars for imaging young planets. "It is one of the very youngest stars this close to the Sun. 51 Eri was born 20 million years ago, 40 million years after the dinosaurs died out," added study co-author Eric Nielsen, post-doctoral researcher at Stanford and the SETI Institute.
