Probing an 'Invisible' Exoplanet's Atmosphere 28

astroengine writes "To study the atmospheres of planets beyond the solar system, astronomers have had two choices: pick one that flies across the face of its parent star relative to Earth's perspective (an event known as a transit), or wait for a new generation of more sensitive space telescopes that can directly capture the planet's faint light. Now, there's a third option. Using a cryogenically-cooled infrared detector on a telescope in Chile, astronomers ferreted out beams of light coming directly from Tau Boötis b, a massive planet about 50 light-years from Earth."
