World's largest optical telescope gets construction approval

By - April 17, 2013 24 Pictures
The world’s largest optical telescope got the go ahead last Friday when the Hawaiian Board of Land and Natural Resources (BLNR) granted a building and operating permit for the Thirty Meter Telescope (TMT) to be sited on a plateau of Mauna Kea on the island of Hawaii. The next-generation telescope, which uses a 30-meter (98 ft) segmented mirror promises to capture images from the near-ultraviolet to the mid-infrared wavelengths with unprecedented clarity.

High-tech imaging reveals atmospheric composition of multiple exoplanets

By - March 26, 2013 8 Pictures
While the number of exoplanets so far identified is steadily marching towards the 1000 mark, fewer than twenty have been discovered in the course of direct observation by astronomical telescopes. Four of them (HR 8977 b,c,d,and e) circle an unprepossessing A5 star called HR 8977, which lies about 130 light-years distant from Earth. Thanks to the little-known astrophysics research arm of the American Museum of Natural History (AMNH), we now have the ability to examine the makeup of their atmospheres by taking simultaneous spectrographs of all four planets.

ALMA inaugurated after rewriting history of stellar "baby boom"

By - March 14, 2013 4 Pictures
Even before the Atacama Large Millimeter/submillimeter Array (ALMA) was inaugurated this week, it was already rewriting history with its observations showing that a stellar baby boom took place much earlier than previously thought. But the pre-inauguration announcement isn’t a reflection that the ALMA team didn’t get to enjoy the official ceremony – like the first images released in 2011, the observations were taken while ALMA was still under construction.

Binary star system found right under our noses

By - March 13, 2013 3 Pictures
In a day when we have examined astronomical objects shining forth from a time shortly after the Big Bang, one would think astronomers have a pretty good handle on what is in the immediate vicinity of the Solar System. That's why the recent report of a binary star lying only 6.5 light-years away came as rather a surprise to the astronomical community. The pair, called WISE J1049-5319 A and B, are brown dwarf stars and only two star systems – the triple star Alpha Centauri, and Barnard's Star – lie closer to our Sun. Read More

Smallest-ever astronomical satellite launched

By - February 25, 2013 3 Pictures
At the Satish Dhawan Space Centre in Sriharikota, India this morning (Feb. 25), the smallest astronomical satellite ever built was launched into orbit aboard the Polar Satellite Launch Vehicle C20 rocket. In fact, it wasn’t just one satellite, but two – each of the twin BRIght Target Explorer (BRITE) spacecraft take the form of a cube that measures just 20 cm (7.8 inches) per side, and weighs in at under seven kilograms (15.4 lbs).
