NASA’s Upper Atmosphere Research Satellite (UARS) has finally returned home after two decades in orbit, and it couldn’t have crash-landed in a better place: a 500-mile-wide swath of the South Pacific. The falling six-ton satellite–which had been expected to re-enter the atmosphere for a couple of weeks, causing some degree of worry–plunged into a part [...]
ALMA’s Very first Picture This really is ALMA’s very first picture, displaying the actual Antennae Galaxies within 2 various wavelength runs. The actual picture had been taken throughout the observatory’s earlier screening stage, only using 12 antennas operating collectively — the actual variety may ultimately possess 66. Western The southern area of Observatory The actual [...]
Last week’s bombshell physics news–those superluminal neutrinos that CERN’s OPERA experiment clocked moving faster than the speed of light–are already getting the rigorous vetting that OPERA’s researchers were hoping for. And some physicists are already rejecting the notion that CERN’s neutrinos broke the cosmic speed limit outright. A paper posted late last week, titled [...]
