Exoplanet is Gobbling Up Gas and Dust as it Continues to Build Mass
This illustration of the newly forming exoplanet PDS 70b shows how material may be falling onto the giant world as it builds up mass. Researchers got a unique look at radiation from extremely hot gas falling onto the planet with Hubble Space Telescope, allowing them to directly measure the planet’s mass growth rate for the first time.

AUSTIN, Texas The Hubble Space Telescope has allowed astronomers from The University of Texas at Austin to get a rare look at a young, Jupiter-sized planet that is growing by feeding off material surrounding a young star 370 light-years from Earth.

NASA s Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star. We just don t know very much about how giant planets grow, said Brendan Bowler of the University of Texas at Austin. This planetary system gives us the first opportunity to witness material falling onto a planet. Our results open up a new area for this research.
