It's still on Earth for the next two years, but the James Webb Space Telescope turned around to face the world this week, as it moved into position for preliminary optics testing. Once it's launched, JWST will study galaxy, star and planet formation in the universe using infrared wavelengths. For now, you can spy on the cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Maryland where JWST is hanging out for the next few months, via the Webb Cam, here.
There are secrets space can't keep. When the National Reconnaissance Office launched an object into space earlier this month, we knew only rough details: the size of the rocket used (large), the nature of the agency launching it (reconnaissance), and the levels of secrecy around the payload (many). Now, thanks to the work of amateur astronomers, we have information that's impossible to conceal: where, exactly, the object is in orbit--plus, what it might be.
Ever wonder what would happen to your eye if you stared at the sun through a telescope? What's the worst that could happen, right? Well apparently it literally burns a hole into your eye, or at least that's what happened when some Youtube scientists held a pig's eye up to the eyepiece of a telescope for a few seconds.
