NASA - Extreme Winds Outside Solar System

Image
A First:  Extremely High Winds Tracked  on a Huge Object Outside of Our Solar System Source:  NASA Winds on a "Failed Star" of 1,450 MPH NASA has achieved yet another first in space.   NASA scientists have clocked winds of 1,450 mph on a huge "brown dwarf" or failed star, that  is 33.2 light years away and outside of  our solar system.  The object is the size of Jupiter, the largest planet in the solar system, and 40 times Jupiter's mass. The winds are extremely fierce. This discovery is a first for astronomers. Previously they were only able to measure winds speeds on planets and objects within our solar system. Whole New Worlds The scientists say this discovery opens the way to understand atmospheres unlike anything in our solar system. The technique they used to make this discovery is also a first. The discovery was made by combining the detection  of radio and infrared emissions from the brown dw
