Stanford astronomers observe the birth of an alien planet

19 November 2015 Astronomy Now

Stanford University researchers announce evidence of an exoplanet being born that could move us one step closer to understanding the process of planet formation around other stars. The alien planet, called LkCa 15 b, orbits a star 450 light-years away and appears to be on its way to growing into a world similar to Jupiter.

Watching an exoplanet in motion around a distant star

A team of astronomers, using the Gemini Planet Imager (GPI) on the Gemini South telescope in Chile, has given us our best view yet of an exoplanet moving in its orbit around a distant star. A series of images captured between November 2013 and April 2015 shows the exoplanet β Pictoris b as it moves through 1½ years of its 22-year orbital period.

Astronomers discover nearby Jupiter-like exoplanet enshrouded in methane

13 August 2015 Astronomy Now

The Gemini Planet Imager instrument has discovered and photographed its first planet. Dubbed 51 Eridani b, the body is a methane-enshrouded gas giant that is the most Jupiter-like exoplanet ever directly imaged, in a planetary system just 20 million years old. It may hold the key to understanding how large planets form in the swirling accretion discs around stars.
