The discovery of an exoplanet that is essentially still in its infancy is an important step to understanding how planets, including the Earth, form.
How do some gas giant planets end up so feverishly close to their stars? NASA's Spitzer Space Telescope finds new clues.
For the last three years, the world's only robotic adaptive optics system, Robo-AO, has been making new discoveries with the 60-inch telescope at Caltech's Palomar Observatory north of San Diego. Now, the instrument, developed at Caltech, is moving to a new home: the 2.1-meter telescope at Kitt Peak National Observatory in Arizona.
