The discovery, published in Geophysical Research Letters, was carried out by analyzing the data obtained by the Cassini spacecraft of NASA and the European Space Agency. As explained scientists have analyzed two overflights conducted in 2007 by the ship, which has since 2004 analyzing the satellite's atmosphere.

So far, scientists knew that Titan's atmosphere was composed of 98.4 percent nitrogen by 1.6 percent methane and between 0.1 and 0.2 percent hydrogen and small amounts of other compounds. But new data determinate that a previously uncatalogued atmospheric component.

Experts have noted that the issuance of the unidentified compound that produces a very strong signal, is present during daylight hours on Titan, from 600 to 1,250 kilometers of its surface with an especially intense peak at 950 kilometers.

That evening fades indicates that it must be a compound that is excited under solar illumination conditions is either destroyed during the hours of darkness.
