Astronomers clock extremely high winds on an object outside of our solar system

by Ashley Strickland, CNN

For the first time, scientists have been able to measure the wind speed on an object outside of our solar system, according to a new study. The object, known as a brown dwarf, is 33.2 light-years away from Earth.

Brown dwarfs aren’t quite stars, but they’re not planets either. These so-called “failed stars” are too big to be planets. The brown dwarf in this study is the size of Jupiter, the largest planet in our solar system, but it has 40 times the mass of Jupiter.

On the nearby cool brown dwarf 2MASS J1047+21, scientists clocked wind speeds reaching 1,450 miles per hour. The study published Thursday in the journal Science.

Previously, scientists have only been able to measure wind speeds on planets and bodies in our solar system. The new findings ruled out models that were used to guess wind speeds outside of our solar system.
