A proposal released earlier this month calls for a giant orbiting space telescope that may revolutionize astronomy.
Are we really doing enough to find asteroids, especially the smaller ones that could destroy a city? A private initiative urges a rapid ramp-up of the search effort — but not everyone agrees.
On December 5th, NASA successfully launched the first test flight of its Orion capsule. Scheduled to carry astronauts beyond low-Earth orbit in the 2020s, the spacecraft is NASA’s first deep-space people transporter since the Apollo days.
Despite funding pushback in the House of Representatives, NASA is full steam ahead in plans for its asteroid retrieval mission.
Thanks to a detector carried across interplanetary space aboard NASA's Curiosity rover, researchers now have a much clearer idea of radiation exposure that future astronauts will endure when traveling to and from Mars.
From international travel to interplanetary probes, the U.S. budget cuts are having impacts on both ground- and space-based astronomy.
Not content to let private companies have all the fun in asteroid exploration and exploitation, NASA managers have proposed a high-flying mission that would capture a small asteroid and dispatch astronauts to study it — all within the next decade.
Deep Space Industries, Inc, announced plans to send a fleet of asteroid-prospecting to target asteroids in 2015 — and that’s just the first step in their ambitious proposal.
The impending closure of the United Kingdom Infrared Telescope might be averted if the observatory’s director can find a buyer.
Uwingu, a small start-up company, wants to change the way science educators, astronomers, and space researchers do business.
A new report by the U.S. National Academy of Sciences examines how studies of the Sun and its influence on Earth have advanced in the past decade and makes recommendations for what should be tackled next.
Pluto, quasars, and total solar eclipses over Easter Island were just a few of the topics that came up at the close of the first week of the international astronomy conference in Beijing.
The budgetary writing is on the wall: the National Science Foundation doesn't have enough money both to operate all of its existing facilities and to build big, expensive new ones. Something's got to give.
Astronomers warn that it's not a question of "if" Earth will be hit by an asteroid, but "when." If a private group of space veterans has its way, a Sun-orbiting spacecraft will find threatening objects decades before they can strike us.
A cadre of space entrepreneurs has hatched a plan to identify thousands of small near-Earth asteroids — and then to exploit the mineral wealth that many of these space rocks are certain to contain.
A group of scientists, policy-makers, and science journalists recently tackled the tough who-where-how-and-why questions that will have to be answered if astronomers discover an asteroid or comet on a collision course with Earth.
Despite threats by the House of Representatives to cut funding, the James Webb Space Telescope plans move ahead.
NASA's next-generation space observatory is already woefully over budget and behind schedule. But if Congressional money-minders have their way, the project will be killed outright in the months ahead.

If you had $12 billion to spend on ground- and space-based observatories over the next 10 years, how would decide what to build? A 255-page National Research Council study, just released, provides some answers.
Charles Bolden, who took the reins of NASA last July, made an appearance in Boston last week and offered some views about the space agency's future.
The Obama administration abandons NASA's Constellation Moon program, but sets its sights farther afield.
A meaty review of the impact hazard facing Earth has just been released by the U.S. National Research Council. The bottom line? If Congress and NASA are serious about finding all the truly threatening asteroids in our planet's vicinity, they'd better fund the search properly.
A globetrotting mascot gets a behind-the-scenes tour of the world's largest single-dish radio telescope.
