Astronomers say the Jupiter-like planet, which is around 100 light-years away from us, resembles an infant version of Jupiter.
The new planet, found by the Gemini Planet Imager (GPI), is known as 51 Eridani b. It is around 20 million years old and has an extremely strong methane signature. In fact, it’s the strongest methane signature that has ever been detected on an alien planet.
As well as the methane signature, astronomers also detected water thanks to the GPI’s spectrometer instrument.
These findings suggest that 51 Eridani b is very similar to planets in our Solar System.
