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.

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.

Mercury passed in front of the sun today. It was the first time that Mercury had passed between Earth and the Sun since 2006, and it was something amazing to see.

Last year record-setting "wildfires" (it's what they call bushfires, poor dears) raged across North America, and this year firefighters across the continent are bracing for another bad season.

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.
