Sometimes two telescopes are better than one. Data gathered by the European Space Agency's Herschel Space Observatory and NASA's Spitzer Space Telescope have provided astronomers with an extraordinary view of young stars' growing pains. Combining two types of infrared vision revealed previously undetected bursts of stellar activity, with much faster cycles of heating and cooling than expected. The observations provide important data, which will help astronomers more fully understand the stages of developing stars.
