Unlocking the secrets of the ringed giant and its moons
NASA uses orbiting observers and robotic landers to investigate the planets, moons, comets, and asteroids of our Solar System.
05.15.13 - Scientists using images from NASA's Mars Reconnaissance Orbiter have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across.
05.15.13 - Asteroid 1998 QE2 will get no closer than about 3.6 million miles at time of closest approach on May 31 at 1:59 p.m. Pacific (4:59 p.m. Eastern).
05.14.13 - The sun's third significant solar flare in under 24 hours -- and the strongest so far of 2013 -- peaked at 9:11 p.m. EDT on May 13, 2013.
05.13.13 - Some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible.
05.10.13 - 2MASX is an ultraluminous infrared galaxy which emits a tremendous amount of light at infrared wavelengths. Scientists connect this to intense star formation.
05.16.13 - NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.
05.15.13 - NASA will host a news teleconference at 4 p.m. EDT, today, May 15, to discuss the status of the agency's Kepler Space Telescope.
05.15.13 - Scientists using images from NASA's Mars Reconnaissance Orbiter (MRO) have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across.
05.09.13 - NASA's Hubble Space Telescope has found the building blocks for Earth-sized planets in an unlikely place-- the atmospheres of a pair of burned-out stars called white dwarfs.
