Huge extrasolar planet, which many astronomers thought the "dead and buried", came back to life, researchers say.

A new study of the results of observations made ​​space telescope "Hubble", found lying around nearby star Fomalhaut us really exists giant exoplanet, which scientists dubbed exoplanets, "zombies." These findings oppose the results of other recent studies claiming that the so-called "planet" - known as Fomalhaut b - is actually a huge cloud of dust.


A team of astronomers led by Curry Secret University of Toronto was able to record the presence of a planetary object in the observation of the "Hubble" for the years 2004 - 2006. In three different wavelengths of visible light. In his new work, scientists were also able to determine the orbital characteristics of Fomalhaut b, confirming that the gravity of the planet could have formed around the disc of debris, seen by previous researchers.

The work was approved for publication in The Astrophysical Journal Letters.
