Fomalhaut b regains planetary status

Fomalhaut b regains planetary status | TG Daily: "The nearby star Fomalhaut does host a massive exoplanet after all, say NASA scientists following a second look at Hubble data.

Back in 2008, astronomers announced that they'd discovered a planet, named Fomalhaut b, shrouded by dust as it orbited Fomalhaut some 25 light-years away.

More recent studies, though, have claimed that this interpretation is wrong. Based on the object's apparent motion and the fact that NASA's infrared Spitzer Space Telescope failed to detect it, they argue that the object is a short-lived dust cloud unrelated to any planet.

Now, though, NASA says that the original theory was probably correct."
