Over the last two decades, the discovery of thousands of exoplanets outside our solar system has shaken up old theories about how planets form;the recent discovery of an "infant Jupiter," rich in methane, may be one step toward writing a new one.

A very young gas giant planet called 51 Eridani b, located 96 light-years from Earth, has a methane-rich atmosphere, just like Jupiter. This is a first, according to a statement from Stanford University: the handful of gas giant atmospheres that scientists have been able to study contain only trace amounts of methane, despite what scientists anticipate for those types of planets.
