Two black holes in the middle of a galaxy are gravitationally bound to each other and may be starting to merge, according to a new study.
JPL’s venerable Ed Stone, the Project Scientist for the Voyager spacecraft for over 40 years, made an appearance on the Colbert Report last night, bantering easily with the no-holds-barred host and discussing the significance of the Voyager mission, from the two launches in 1977 to Voyager 1′s recent celebrated arrival in interstellar space.
Colbert also was tasked by NASA to present Stone with NASA’s Distinguished Public Service Medal for a lifetime of scientific achievement. See below:

The next few years will be banner ones for learning about dwarf planets. While the high-profile New Horizons spacecraft zooms towards a Pluto date in 2015, the Dawn spacecraft is making a more stealthy (in terms of media coverage) run at Ceres, which is the smallest and closest dwarf planet to Earth.
The Dawn spacecraft, as readers likely recall, made its first port of call at fellow protoplanet Vesta. What excites scientists this time around is the likelihood of water ice on Ceres’ surface. Vesta, by contrast, was very dry.
Here’s Dawn’s agenda once it gets to Ceres in April 2015:
CAPE CANAVERAL AIR FORCE STATION, FL – SpaceX scored a spectacular launch success this evening (Dec. 3 ) when the maiden flight of their upgraded Falcon 9 rocket from Florida scorched the sky of the Florida Space Coast and successfully delivered a commercial space satellite to geostationary orbit for the first time ever – thereby revolutionizing the commercial space industry from this day forward.
The third time was finally the charm as the Falcon 9 blasted off precisely on time at 5:41 p.m. EST from Launch Complex 40 at Cape Canaveral following a pair of launch scrubs last week on Nov. 25 and Thanksgiving Day Nov. 28 caused by technical problems with the first stage engine.
