Everyone seems to be double-extra-cautiously optimistic about this finding, so don’t go running out to your telescope tonight looking for greetings from friendly space creatures.
But in work reported today in Nature, astronomers say they used the Hubble Space Telescope’s infrared imager to pick up signs of methane in the atmosphere of a Jupiter-sized planet orbiting a star some 63 million light years from Earth. And methane, an organic molecule, is an indicator of the possible presence of life.
The bad news, for ET fans, is that the planet is probably too close to its host star to support the kind of life we’re all really looking for. The good news is that the very presence of methane, and water, in the planet’s atmosphere could be evidence that some form of life may be out there, either on this planet or others. Methane is key to the formation of amino acids, the basic building blocks of organisms.
Another key takeaway from this work, scientists say, is that astronomers have now moved from simply finding these planets—a not-so-simple job in and of itself—to exploring them chemically.

I just wonder how do they get the Hubble Telescope to see such
images.
Hydroline - They took an infra-red spectrum while the planet was in front of the star. Then, they looked for methane and H20 absorption lines in that spectrum. To verify these results, they waited for the the planet to move out of the star's line of sight, and noted that these absorption lines disappeared.

This is a interesting topic though im going to keep taps on this planet

Anything with energy applied to it, which is everything, can be sensed in whatever spectrum of energy it is applied to, humans can only see the spectrum of shade, and white light - colour, not gamma, infared or cyan, just the wavelengths that existed in out environment, but technology can see what we understand and what we understand we incorperate into technology to increase our understanding. Mabye methane can reflect a certain wavelength of energy but i would say imaduck is probably correct

Perhaps there are methane entities there :-p
