Due to launch in the Spring of 2012, NASA's NuSTAR mission will scan for lively black holes, radioactive supernova remnants, galactic jets that shoot out at nearly light-speed and other sources of high-energy X-rays.
The Morning Star appears to pass across the face of the Sun at regular intervals of 8, 121.5 and 105.5 years. In 2004, NASA's TRACE spacecraft captured the event and in June 2012 humans will see the last transit before the pair in 2117 and 2125.
April Fools! In a response to critics who believe NASA is photoshopping their content, here's a comical take on an Astronomical Image Enhancement Engineer whose main job is to remove the feisty felines who live in Space.

As NASA’s Dawn spacecraft investigates its first target, the giant asteroid Vesta, Marc Rayman, Dawn’s chief engineer, shares a monthly update on the mission’s progress.
This image from NASA’s Dawn spacecraft shows a young crater on Vesta that is 9 miles (15 kilometers) in diameter. Layering is visible in the crater walls, as are [...]
NASA's Kepler Mission, a space-based telescopic camera, has discovered planets orbiting stars beyond our Sun. Though an Earth-like planet in the "Goldilocks Zone" hasn't yet been positively identified, astronomers believe it's just a matter of time.
X-ray observations of supernova Cassiopeia A by the orbiting Chandra X-ray Observatory show that some of the innermost elements are now located near the outer edges of the remnant; proof of the explosion's power

Clearly carrying heavy shielding to protect astronauts from radiation in space is expensive. If you havent' been reading my space radiation series as I've been posting, then you can look over the last several of my postings about space radiation to see some of the problems. So, some other strategy ...
Part 3 of my series on space radiation is about the radiation itself. The term cosmic rays is generally used to describe this radiation. Unfortunately, as often happens, the term evolved before the nature of the phenomenon being studied was known, so it may not be the best term to ...
