This is excellent news, since I like to have a nice steak after a long space voyage.
Methane Detected on Distant Planet for First Time
Methane has been detected in the atmosphere of a planet outside our solar system, the first time that an organic molecule has been found on a distant world.Mmmmmm.... space cows.....
Studies of this carbon-bearing compound could shed light on the planet's formation and evolution.
The planet, known as HD 189733b, is a so-called hot Jupiter, a gas giant similar to Jupiter that orbits very close to its parent star.
The far-flung world, discovered in 2005, is 63 light-years away in the constellation Vulpecula.
In 2007 astronomers detected signs of water on HD 189733b using NASA's Spitzer Space Telescope.
Now, using the Hubble Space Telescope, scientists have confirmed the presence of water and also detected methane.
Planets outside our solar system, called exoplanets, are so far away that scientists can't obtain images clear enough to separate the planet from its star.
So to study HD 189733b, the team used an instrument aboard Hubble called a spectrometer, which breaks up light passing through a planet's atmosphere into different bands.
"The big news is that this is the first detection of an organic in an exoplanet atmosphere," said lead study author Mark Swain, a researcher at the Jet Propulsion Laboratory and the California Institute of Technology.
The study appears in this week's issue of the journal Nature.
