All systems go for construction of world's largest optical telescope

By - June 3, 2015 5 Pictures
The construction of the largest optical telescope ever built has moved one step closer today, with US$500 million in funding now committed from 11 international partners. Set to be the world's biggest and most powerful, the Giant Magellan Telescope is constructed from seven huge mirrors that will span a total of 25.4 meters, bringing in six times more light than any other large telescope. It is also claimed that the instrument will be able to resolve images up to ten times more clearly than the space-based Hubble telescope. Read More

DARPA wants ideas for imaging distant satellites from Earth

By - May 16, 2015 1 Picture

If you browse the internet, it's easy to find an image of the International Space Station taken by an amateur astronomer that looks as if it was taken only a mile away. DARPA wants to go several magnitudes better with a telescopic system that can take detailed images of satellites in geosynchronous orbit. The research agency is seeking ideas on how to achieve this from an unorthodox mix of small businesses, academic and research institutions, and first-time government contractors.

Earth-sized virtual telescope to study supermassive black hole at center of Milky Way

By - April 29, 2015 3 Pictures
In astronomy, much like many other other aspects of life, bigger is better. Taking this adage to heart, astronomers at the University of Arizona are helping to build a virtual radio telescope the size of the Earth itself. With a resolution factor more than a thousand times greater than that of the Hubble Space Telescope, the new Event Horizon Telescope (EHT) will be used to study in fine detail the supermassive black hole at the center of our Milky Way.

Lasers could be used to zap orbital debris

By - April 17, 2015 1 Picture
Orbital debris is increasingly becoming a hazard to satellites and other spacecraft, which is why various groups have proposed concepts such as gas clouds, nets and sails for collecting it. While those approaches could capture larger objects, the problem of smaller pieces of debris – which whiz around the Earth like bullets – would remain. That's why an international group of scientists is developing a system that could shoot those bits down with a laser. Read More
