Hubble detects stratosphere-like layer around exoplanet
Jun 11, 2015 (UPI)
Researchers say they've identified a protective stratosphere-like layer around an exoplanet called WASP-33b. The layer acts a sort of sunscreen, protecting the ...
Hubble in 'Oh Planet, What Art Thou?' 25th Anniversary Video
Jun 09, 2015 (SPX)
