Something odd happened a few months after NASA’s deep space probe New Horizons was launched Jan. 19, 2006—its target got demoted from a planet to a “dwarf planet.” In [...]

NASA's Hubble Reveals Rogue Planetary Orbit for Fomalhaut B

This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. The planet will appear to cross a vast belt of debris around the star roughly 20 years from now. [...]

Dawn's Vesta Departure Delayed

The Dawn spacecraft, which is currently orbiting the large asteroid Vesta, has had issues with its reaction wheel crop up. This will cause its departure from the tiny world to be delayed. Image Credit: NASA / JPL-Caltech/UCLA/McREL

NASA’s Dawn spacecraft will be staying at the large asteroid Vesta a little longer than originally planned. [...]
