I am hypnotized by this giant-headed mystery woman who helped make the atomic bomb

Nuclear historian Alex Wellerstein has made something chilling and beautiful. He took all of the badge photos of the people who devised the atomic bomb during World War II at Los Alamos, and he built a mosaic.<p>The badges are an amazing piece of history, but with this mosaic, they've been turned into …

Water on Earth predates the solar system, and even the sun

Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research.<p>That makes them older than the Earth, older than the solar system — even older than the sun itself.<p>In a study published Thursday in Science, researchers say the distinct …

The Strongest, Most Expensive Material on Earth

Graphene's most problematic superlative is its cost.<p>It was so simple. Take a small flake of graphite and put it on piece of regular old Scotch tape. Pinch it in between the tape, peeling off layer after layer until it leaves only the vaguest, most transparent of marks. Transfer those dustings onto …

APOD: Two Black Holes Dancing in 3C 75 (2014 Sep 28) Image Credit: X-Ray: NASA/CXC/D.Hudson, T.Reiprich et al. (AIfA); Radio: NRAO/VLA/NRL http://apod.nasa.gov/apod/ap140928.html Explanation: What's happening at the center of active galaxy 3C 75? The two bright sources at the center of this composite x-ray (blue)/ radio (pink) image are co-orbiting supermassive black holes powering the giant radio source 3C 75. Surrounded by multimillion degree x-ray emitting gas, and blasting out jets of relativistic particles the supermassive black holes are separated by 25,000 light-years. At the cores of two merging galaxies in the Abell 400 galaxy cluster they are some 300 million light-years away. Astronomers conclude that these two supermassive black holes are bound together by gravity in a binary system in part because the jets' consistent swept back appearance is most likely due to their common motion as they speed through the hot cluster gas at 1200 kilometers per second. Such spectacular cosmic mergers are thought to be common in crowded galaxy cluster environments in the distant universe. In their final stages the mergers are expected to be intense sources of gravitational waves. http://www.nasa.gov/ http://chandra.harvard.edu/ http://arxiv.org/abs/astro-ph/0603272 http://www.astro.uni-bonn.de/ http://www.vla.nrao.edu/ http://www.nrl.navy.mil/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140928 #APOD
