Holy cow. So you can cause sub-cellular-level changes by just working out, improving your entire body's function. If ever you needed a reason to start exercising right now, here it is.

X-Men, here I come!

Astro-Porn of the Day: Time-Lapse Movie of the Earth from the Space Station

In honor of the gorgeous aurora those of you who live in the high (and low) lattitudes are enjoying tonight, behold "All Alone in the Night,"

Explanation from NASA: Many wonders are visible when flying over the Earth at night. A compilation of such visual spectacles was captured recently from the International Space Station (ISS) and set to rousing music. Passing below are white clouds, orange city lights, lightning flashes in thunderstorms, and dark blue seas. On the horizon is the golden haze of Earth's thin atmosphere, frequently decorated by dancing auroras as the video progresses. The green parts of auroras typically remain below the space station, but the station flies right through the red and purple auroral peaks. Solar panels of the ISS are seen around the frame edges. The ominous wave of approaching brightness at the end of each sequence is just the dawn of the sunlit half of Earth, a dawn that occurs every 90 minutes.

Enjoy!
