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. 30 Doradus is the brightest star-forming region in our galactic neighbourhood and home to the most massive stars ever seen.

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? “There’s maybe a loophole here” for space property rights, Rand Simberg said. Continue reading
A group of European astronomers has discovered an ancient planetary system that is likely to be a survivor from one of the earliest cosmic eras, 13 billion years ago. The system consists of the star HIP 11952 and two planets, which have orbital periods of 290 and 7 days, respectively. Continue reading
On April 15 the planet Saturn will be at Opposition. The ringed giant will be at its closest approach to the Earth and its face will be fully illuminated by the Sun. It will be the best time to view and photograph Saturn and its moons. 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
On March 3, Mars was at opposition. The Earth passed Mars as the two planets wheeled around the sun in their respective orbits. This time the opposition was an unfavorable one because Mars was at aphelion on February 15, which means it was at its farthest point from the sun. 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
