Scientists have shown off a new laser that boasts an incomparable mix of speed, short pulses and power. That's newsworthy in and of itself, but this laser, developed by researchers at the University of Konstanz in Germany and, here in the U.S., at the National Institute of Standards and Technology, could also lead to a 100-fold increase in the sensitivity of observatories searching for extrasolar planets. The laser itself is the size of a dime, and pops out 10 billion pulses per second with an average power of 650 milliwatts.

We've talked in this space in the past few months about detecting the existence of Earth-like planets in other solar systems, and on the educated guesswork which goes into putting a number on the probability of intelligent life existing out there as well. You may remember that the discovery of terrestrial planets is well on its way as technology improves; and that the Drake equation—with all its assumptions—has proved to be remarkably accurate.

News of another extrasolar planet hardly grabs headlines anymore, now that scientists have pushed the count far above 200. But yesterday a group of astrophysicists says it may have uncovered evidence of a foreign planet being born.

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.
