A newly unveiled company with some high-profile backers — including filmmaker James Cameron and Google co-founder Larry Page — is set to announce plans to mine near-Earth asteroids for resources such as precious metals and water. Continue reading

Several million stars are vying for attention in this NASA/ESA Hubble Space Telescope image of a raucous stellar breeding ground in 30 Doradus, located in the heart of the Tarantula nebula. Continue reading

The clearest view yet of the famous Apollo 11 landing site on the moon was captured by a NASA spacecraft in orbit around our planet’s natural satellite. The agency’s Lunar Reconnaissance Orbiter zeroed in on Mare Tranquillitatis, or the Sea of Tranquility — the place where humans first touched down on the lunar surface on July 20, 1969. Continue reading

Observations by the NASA/ESA Hubble Space Telescope have come up with a new class of planet, a waterworld enshrouded by a thick, steamy atmosphere. It’s smaller than Uranus but larger than Earth. Continue reading

NASA’s solar-powered Juno spacecraft successfully refined its flight path Feb. 1 with the mission’s first trajectory correction maneuver. The maneuver is the first of a dozen planned rocket firings that, over the next five years, will keep Juno on course for its rendezvous with Jupiter. Continue reading

Astronomers using data from NASA’s Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars. Continue reading

This beautiful image of two colliding galaxies has been released by NASA’s great observatories. The Antennae galaxies are located about 62 million light-years from Earth. They take their name from the long antenna-like “arms,” which were produced by tidal forces … Continue reading

This image represents the inner region of galaxy cluster Abell 1689 and the distribution of dark matter around it. Abell 1689 is an immense cluster of galaxies located 2.2 billion light-years away. Continue reading

Astronomers on Tuesday (Dec. 20) announced the discovery of the first two Earth-size alien planets – a historic find for sure, but the newfound worlds didn’t exactly receive historic names. The two alien planets are officially known as Kepler-20e and Kepler-20f, a nod to the instrument that detected them, NASA’s prolific Kepler space telescope. Continue reading
