Astronomers Discover Nearby 'Young Jupiter' Exoplanet

Posted by Soulskill on from the baby-pictures dept.

An anonymous reader writes: Astronomers from Stanford and the Kavli Institute have discovered a new exoplanet orbiting 51 Eridani that strongly resembles a young Jupiter. They say its similarities could help us to understand how our own solar system formed. It's a convenient discovery, because 51 Eridani is less than 100 light-years away, and only about 20 million years old. The discovery was confirmed by astronomers at the Keck Observatory and published in Science (abstract). "In addition to being the lowest-mass planet ever imaged, it's also one of the coldest – 800 degrees Fahrenheit, whereas others are around 1,200 F – and features the strongest atmospheric methane signal on record. Previous Jupiter-like exoplanets have shown only faint traces of methane, far different from the heavy methane atmospheres of the gas giants in our solar system."

      What happens below absolute zero? Do electrons start orbiting backwards?
