First glimpse of Higgs Bosons at work revealed

his 2011 image provide by CERN, shows a real CMS proton-proton collision in which 4 high energy electrons (green lines and red towers) are observed in a 2011 event. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes. To cheers and standing ovations, scientists at the world's biggest atom smasher claimed the discovery of a new subatomic particle Wednesday July 4, 2012, calling it "consistent" with the long-sought Higgs boson popularly known as the "God particle" that helps explain what gives all matter in the universe size and shape.

NASA Preps for nail-biting comet flyby of Mars

Simulation depicts comet C/2013 A1 Siding Spring during its close Mars flyby on Oct. 19. Its nucleus will miss Mars by about 82,000 miles (132,000 kilometers). The comet’s trail of dust particles shed by the nucleus might be wide enough to reach the planet. Click to see the interactive, animated view. (Credit: Solarsystemscope.com)

Listening in on cosmic messages

Mapping signals on the sky can offer clues about where the signals originate. Pulsars (top) concentrate in the Milky Way, because most of the ones we see sit in our galaxy. Gamma bursts (middle) come from everywhere, which means they’re parked in other galaxies. Fast radio bursts (bottom) seem to mostly avoid our galgaxy, a hint that they may come from very far away.(Credits: Green Bank Telescope, West Virginia Univ; G. Fishman et al/BATSE, CGRO, NASA.; J.

Large number of dark matter peaks found using gravitational lensing

This map shows the distribution of dark matter (black) in the Universe, overlapping with optical measured clusters of galaxies (red circles). The mass peaks in the map contain significant cosmological information, will provide us with an improved understanding about the dark side of the Universe. The size of this map is about 4 square degrees corresponding to only 2.5% of the full CS82 survey footprint shown in the next figure. (Credit: CS82, SDSS)
