• 11:12 Cartwheel Coronal Mass Ejection

  Read the story at NASA
  Imagine a billion-ton cloud of gas launching itself off the surface of the sun and then ... doing a cartwheel. That's exactly what happened on April 9, 2008, when a coronal mass ejection or "CME" pirouetted over the sun's limb in full view of an international fleet of spacecraft.

• 20:44 Lunar GRAIL

  Read the story at NASA
  Gravitationally speaking, the moon is a strange place. Satellites in lunar orbit feel odd, sideways tugs and end up nose down in the moondust. Astronauts standing in the middle of lunar lava seas weigh more than they do standing on the shore. A new NASA mission named GRAIL aims to map the moon's quirky gravity field and thus pave the way for future exploration.

• 22:31 A Super Solar Flare

  Read the story at NASA
  In September 1859, a solar flare erupted so intense that the explosion itself was visible to the human eye. A ferocious geomagnetic storm ensued in which Northern Lights descended as far south as Cuba, the Bahamas and Hawaii. Meanwhile, telegraph engineers disconnected their batteries and powered communications by electricity from the auroras! Could it happen again?
