Nasa completes first internal review of concepts for asteroid redirect mission
NASA has completed the first step toward a mission to find and capture a near-Earth asteroid, redirect it to a stable lunar orbit and send humans to study it.
Spitzer discovers young stars with a 'hula hoop'
(Phys.org) —Astronomers using NASA's Spitzer Space Telescope have spotted a young stellar system that "blinks" every 93 days. Called YLW 16A, the system likely consists of three developing stars, two of ...
New Explorer mission chooses the 'just-right' orbit
Principal Investigator George Ricker likes to call it the "Goldilocks orbit"—it's not too close to Earth and her Moon, and it's not too far. In fact, it's just right.
Is life on Mars related to life on Earth?
The idea that there is life on other worlds is humbling and exciting, and finding life on another world would change everything. This has been a driving force for scientists for decades. We find life wherever ...
Astrophysicist determines occurrence rate of giant planets around M-dwarfs
A study led by Notre Dame astrophysicist Justin Crepp has for the first time definitively determined how many of the lowest-mass stars in the galaxy host gas giant planets. The researchers' paper, "The Occurrence Rate of ...
How high is space?
Look up, there's space. Astronomically speaking, it's right there, just outside a thin layer of atmosphere. But how far away is it? How high is space?
Ready for launch tomorrow, Alphasat – Europe's largest telecommunications satellite – will serve as a testbed for advanced space technologies at the same time as it works on its day job as part of the ...

Stars' orbital dance reveals a generation gap
UBC astronomers have used NASA's Hubble Space Telescope to track the orbital motion of 33,000 stars in one of the Galaxy's oldest globular clusters, offering new insights into the formation of the Milky Way.
A new way to see space – even its junk
When a large radio telescope in the Australian outback was unveiled last week its improved sensitivity was immediately apparent. It transformed images of supernova remnants taken with last year's equipment ...
Satellite view shows Opportunity Mars rover still hard at work 10 years on
Ten years to the day after the Opportunity rover launched to Mars, the HiRISE camera on the Mars Reconnaissance Orbiter snapped this image of the rover, still toiling away on the surface of Mars. The white ...
Air-breathing rocket engine gets funding infusion
The technology, which sounds straight out of a science-fiction movie, has enough reality to it for the United Kingdom government to offer $90.62 million (£60 million), in stages, to a company looking to ...
