We found a way to accurately detect clandestine nuclear reactors from afar. The technology is based on detecting the massive amount of antineutrinos emitted, a telltale signature. The author mentioned a fact I found especially interesting. When an antineutrino collides into a proton, a neutron and positron are generated. Not quite proton decay, but really cool.

I find this newly released technology interesting, considering the classified mission of the satellite launched two days ago... I'm not drawing any conclusions but it'd be funny if they were connected, wouldn't it!
"Black Holes Merge With A Flash of Light" by Discover News explains the observations involved in the merging of two supermassive black holes. Now here comes the technical stuff... The event will have a specific distinguishable electromagnetic signature within the frequency of visible light, due to accretion disks heating up. This information will be collected in tandem with Gravity Wave detection, to further confirm the accuracy of the observation. I covered the gravity wave detector LIGO a while back (check back to this post from 9-18-2010.) The Discovery article also explains the recent breakthrough in simulations of black hole mergers with large size ratio differences, such as 1:100. I covered that story a while back as well. (check back to this post from 11-19-2010.) The Discovery News article does a good job explaining the idea, but with the links provided here you should be able to truly get a full grasp of what's going on. Article on Discovery News
Check out this mindblowing video showing a 3d version of two black holes of equal size merging, with gravity wave line mapping.
