A company named DE-star has released their latest video on their laser propulsion project. The projects aims are to develop a realistic means of deflecting an asteroid on a collision course with Earth, and a means of photon based propulsion for interstellar space craft. A poster explaining how the technology would enable a range of missions to the nearest stars is here.

Pluto's Moon Charon has been known for a while to have a mysterious reddish cap over one pole. Now the New Horizons team think they understand why - the cap is actually part of Pluto's atmosphere
Tornado of iron vapour on the sun:
The Solar Dynamics Observatory can look for different frequencies of light, such as those that correspond to vapourised iron in the Sun's atmosphere. Which it how it spotted this titanic tornado in the super hot gas of the Sun's atmosphere...
Ceres's bright spot's definitely not made of ice:
The latest images from the Dawn mission, currently in orbit around Ceres has given us the closest views yet of the dwarf planets mysterious bight spots, and now scientists know... that they're still confused. Occator crater contains some very odd geology, including very bright deposits, systems of cracks, and an odd triangular hole in the surface.
