Astronomers using NASA's Chandra observatory were able to witness an eclipsing planet for the first time.
Using imagery from the Hubble Space Telescope, astronomers have determined that a planet orbiting a star close to our solar system has a deep azure blue color when seen from space, much like Earth.
Astronomers search for planets using several different techniques; the most popular of which is to measure how a star "wobbles." As the surrounding planets orbit the star, their gravitational fields will cause the star to shift back and forth in response.
Astronomers have observed one planet in another solar system, similar to Jupiter, giving off a powerful burst of evaporation after passing by its parent star.
NASA astronomers have successfully demonstrated that a David of a telescope can tackle Goliath-size questions in the quest to study Earth-like planets around other stars.
Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, advancing astronomers toward the goal of being able to characterize planets where life could exist.
