Hasta La Gadget!

Space junk is an undeniable problem when there’s over 500,000 dead satellites, spacecraft pieces and other human-made obstacles that could crash into active orbiting vehicles. DARPA is more than a little overwhelmed in trying to track all those hazards by itself, so it’s recruiting amateur help through its new SpaceView program. The effort will buy time for non-professional astronomers on existing telescopes, or even supply hardware directly, to track the spaceborne debris without the sheer expense of growing an existing surveillance network. While that amounts to using hobbyists purely as volunteers, DARPA notes that the strategy could be a win-win for some when hardware donated for SpaceView could be used for regular astronomy in spare moments. The challenge is getting through the sign-up phase. While SpaceView is taking applications now, it’s initially focusing on options for standard commercial telescopes and hand-picking those who have permanent access to hardware in the right locations — there’s no guarantee a backyard observatory will pass muster. Those who do clear the bar might sleep well knowing that satellites and rockets should be that much safer in the future.

That picture above is the deepest and most detailed view of the universe ever captured. It’s called XDF, or eXtreme Deep Field, and was created using Hubble Telescope data from 2003 and 2004. It combines ten years of NASA Hubble Space photographs of a single sky sample into one full-color historic view of the galaxies. Hubble pointed at this patch of the constellation Fornax for fifty days, with an exposure time of 2 million seconds. A dazzling trip back in time, the image reveals almost 5,500 galaxies that include Andromeda, spirals similar to the Milky Way, along with remnants of galactic collisions. According to NASA, the XDF reveals galaxies that go as far back as 13.2 billion years.

There’s a video after the break describing how the shot was assembled; those interested in learning even more can participate in a Google+ webinar with the XDF team this Thursday, September 27th. Here’s hoping that when NASA finally gets the James Webb Space Telescope going, we’ll have an even deeper view into our galactic past.

NASA has shown just what it can do with the short window of science allowed by its “sounding” or sensor-equipped suborbital rockets — having taken the sharpest pictures ever of the sun’s corona. A 460-pound telescope called the High Resolution Coronal Imager (Hi-C) was lofted for about 10 minutes into space, ample time for its mirrors to capture over 150 images of the solar fringe at 16-megapixels each, before parachuting back to earth. The scope shot exclusively in a sun-friendly high ultraviolet range and used innovative new optics consisting of an array of mirrors, allowing it to resolve the sun down to 135 miles. That bested the previous champ, NASA’s own Solar Dynamics Observatory, with almost five times the magnification. For maximum effect, the space agency took advantage of an unusually high amount of solar activity to focus on a large, active sunspot. To see the results in glorious multihued HD, check the video after the break.

Just when you’re numbing to robot, zombie and nuclear apocalypse scenarios, some old-fashioned asteroid paranoia pops up to surprise you. The B612 Foundation, which gets funding from, well, anyone, has just announced plans to launch Sentinel, a space telescope which will wander the vacuum cataloging asteroids in our inner solar system. Their goal is to track asteroid orbits and predict large impacts up to 100 years in advance, giving us plenty of time to find a solution (or enjoy our final days). Construction doesn’t start til late fall, with the launch expected in around five years, so it won’t be any use in disproving the 2012 doomsday believers out there. You can find out more about the project and donate to the foundation at the source link, or jump past the break for a video explanation, Aerosmith not included.
