The Space Surveillance Telescope (SST) is designed to track space debris and small objects

In order to dodge something, you need to see it. If that something is space debris then sometimes the best thing to use is an old-fashioned telescope – or, in the case of the US Department of Defense, a state-of-the-art telescope capable of searching an area larger than the United States in seconds. That’s why DARPA is preparing to deliver the new Space Surveillance Telescope (SST) to Western Australia, where it will help track small satellites and space debris orbiting the Earth when it becomes operational in 2016.  Read More

Artist's concept of the foldable plastic telescope

DARPA has announced planes to use a foldable plastic lens to “break the glass ceiling” of space telescopes. It’s part of the agency’s Membrane Optical Imager for Real-Time Exploitation (MOIRE) program, which aims at replacing conventional glass optics with lightweight polymer membranes that may one day make possible a foldable plastic orbital telescope 20 m (65 ft) wide that will be capable of seeing a medium-sized dog on Earth from 36,000 km (22,000 mi) away.  Read More

Astronomers at UC Riverside have combined observations from space and ground telescopes to discover what they say is the oldest known galaxy with a precisely measured distance, seen as it was just 700 million years after the Big Bang.  Read More

On Wednesday, at 12:10:27 GMT, ESA’s Planck space telescope ended its four and a half year mission when project scientist Jan Taube sent the command telling the unmanned probe to switch itself off.  Read More

Artist's concept of Juno arriving at Jupiter (Image: NASA/JPL-Caltech)

Online observatory Slooh has streamed live pictures of NASA’s Juno space probe flyby. The feed from the robotic half-meter telescope in the Canary islands gave visitors a ringside seat as the probe passed within 347 mi (559 km) of Earth in a slingshot maneuver designed to take it all the way to Jupiter.  Read More

The last antenna arrives at the ALMA observatory in Chile (Image: ESO)

The last 12 meter (40 ft) antenna has arrived at the Atacama Large Millimeter/submillimeter Array (ALMA), pushing the project closer to its full operational potential. The final antenna was supplied by the European side of the venture, and completes the 66 dish array stretching across the Chajnantor Plateau in Chile's Atacama Desert. The telescope, which was inaugurated in March 2013, has already made a number of significant discoveries despite its incomplete nature.  Read More

Astronomers have used data from European Southern Observatory telescopes to create a three dimensional map of the central bulge of the Milky Way. The gigantic cloud at the center of our galaxy contains a staggering 10,000 million stars (or thereabouts) and resides around 27,000 light-years away. Despite the relative proximity of the area, prior to these new studies little had been confirmed concerning its origin and structure.  Read More

The life cycle of a Sun-like star, detailing the comparative ages of the Sun, HIP 102152 a...

Astronomers have used the ESO's Very Large Telescope (VLT) to observe the Sun-like star HIP 102152. The object, which resides 250 light-years away, is a solar twin exhibiting very similar attributes to our own Sun. HIP 102152 is nearly four billion years older than the Sun, a characteristic that has provided a valuable insight into the link between the age of a star and the amount of lithium it carries.  Read More

Images taken by the 6.5 meter Clay telescope with and without the new adaptive optics syst...

Astronomers have developed a new visible-light adaptive optics (AO) system for the 6.5 meter diameter Magellan-Clay telescope in Chile's Atacama desert. The new AO system replaces the secondary mirror of the telescope with a thin adaptive mirror that can be deformed by its 585 mechanical actuators at a rate of more than 1000 times a second to correct for the image smearing effects of atmospheric turbulence. The result is the sharpest astronomical images ever produced – more than twice as sharp as can be achieved by the Hubble space telescope viewing objects through the vacuum of space.  Read More

The GMT will be completed in 2020 and sport a resolution 10 times greater than the Hubble ...

Slated for completion by 2020, the Giant Magellan Telescope (GMT) will combine seven of the largest and most precisely built telescope mirrors, to offer image resolutions 10 times greater than Hubble at around one third of the cost. The telescope will be used to study the early universe and answer open questions on dark matter, supermassive black holes, and the nature of planets beyond our solar system.  Read More
