Here is some more information on this recent discovery.  As stated by the team, this is exactly the type of planet/formation that could give us clues on early formations of gas giants like Jupiter.

The planet, dubbed 51 Eridani b, is a million times fainter than its star, 51 Eridani, and shows the strongest methane signature ever detected on an alien planet, which should yield clues as to how the planet formed. The planetary system is very young – around 20 million years old, compared to our own 4.5 billion-year-old solar system – and provides a view of what Jupiter might have looked like in its infancy.

“This is exactly the kind of planet we envisioned discovering when we designed GPI,” said James Graham, a UC Berkeley professor of astronomy and the GPI project scientist. “We wanted to find planets when they’re young so we can figure out the formation process.”

The planet is estimated to be about twice the mass of Jupiter, and orbits at a distance of 13 AU, or slightly farther from its star than Saturn is from the sun.

This is pretty incredible and it makes you wonder just how many undiscovered planets are in our vicinity!

We hope you like the video.
