Where is space?

Obviously the Earth ends and space begins somewhere, but today, as it has been for the entirety of humanity's manned and unmanned exploration of

Solar flares from Skylab

Before automated space observatories like SDO could send pictures and videos of solar phenomenon in real-time, humans had to do it manually, as in the case of the groundbreaking Skylab space station missions, which featured the Apollo Telescope Mount.

Lovely Lovejoy pictures

Just a few of the amazing photos of Comet Lovejoy that have been taken from the southern hemisphere over the last few days.

And only a few weeks later, we have witnessed, with some degree of a shock, the first failure of a Progress mission in many years.

Progress comes to a halt

The first post-shuttle resupply mission in ISS history got off to a rocky start, as a Russian Progress cargo spacecraft failed to reach orbit, crashing into south central Russia.

This photo is making the rounds of Twitter, Facebook, Google+, and whatever other social network you care to name today. It was shot by astronaut Ron Garan from the Space Station, and it's a meteor seen from above. Way cool.
