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

Some space advocates argue that private property rights on the Moon and other bodies are essential to the future of space development. Is there a way to accept property claims under the current treaty regime? 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

With President Barack Obama proposing a relatively flat budget for NASA in 2013, a group professional astronomers is urging the White House and Congress to find a better balance between the space agency’s planetary science and exploration needs. Continue reading

Scientists are keeping a close eye on a big asteroid that may pose an impact threat to Earth in a few decades. The space rock, which is called 2011 AG5, is about 140 meters wide. It may come close enough to Earth in 2040 that some researchers are calling for a discussion about how to deflect it. 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

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

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

Excellent launch precision for NASA’s Mars Science Laboratory mission has forestalled the need for an early trajectory correction maneuver, now not required for a month or more. That first of six planned course adjustments during the 254-day journey from Earth to Mars had originally been scheduled for 15 days after the mission’s Nov. 26 launch on a United Launch Alliance Atlas V rocket.
