Disc may be new planet taking form

NEW YORK, March 26 (UPI) -- U.S. scientists are watching what appears to be the creation of a new planet near a distant star.
Ben R. Oppenheimer, an astrophysicist at the American Museum of Natural History, said he and his colleagues used a coronograph attached to a U.S. Air Force telescope in Hawaii to construct an image of material that appears to be a gas-and-dust cloud coalescing into a solid body form orbiting the star AB Aurigae, the National Science Foundation said Tuesday in a news release.
The report, which will be published in the Astrophysical Journal sometime this year, said the image shows a horseshoe-shaped void in the disc with a bright point appearing as a dot in the void.
"The deficit of material could be due to a planet forming and sucking material onto it, coalescing into a small point in the image and clearing material in the immediate surroundings," Oppenheimer said. "It seems to be indicative of the formation of a small body, either a planet or a brown dwarf."

As part of a national initiative to optimize government-owned wind tunnels, NASA's Langley Research Center shut down the tunnel and transitioned work to other facilities. During its operational lifetime, the tunnel supported development of all fighters since the 1960s, such as the F-14, F-15, F-18 and the Joint Strike Fighter. (UPI Photo/NASA)
