NASA: Sun’s corona much larger than previously thought

Scientists used these observations of the sun's atmosphere (the bright light of the sun itself is blocked by the black circle at the middle) from NASA's Solar Terrestrial Relations Observatory on Aug. 5, 2007, to define the outer limits of the solar atmosphere, the corona. (Credit: NASA/STEREO)

Confirmed: That Was Definitely the Higgs Boson Found at LHC

Candidate Higgs boson events from collisions between protons in the LHC. The top event in the CMS experiment shows a decay into two photons (dashed yellow lines and green towers). The lower event in the ATLAS experiment shows a decay into 4 muons (red tracks).[

Clumped galaxies give General Relativity its toughest test yet

More than 600 000 galaxies from the BOSS survey were utilized to measure the strength of gravitational interactions of galaxies extremely far away from each other. This is a visual representation of that measurement; the amount that the circles are distorted, or squashed from perfect concentric rings, indicates the velocity that galaxies are falling towards each other and hence the strength of the gravitational interactions.

How the Aged Vacuum Tube Could Save Moore’s Law

One of the bulbs Thomas Alva Edison used to discover thermionic emission (the Edison Effect) in 1884. Edison found when he connected an ammeter between the filament and the auxiliary electrode, a current would flow, passing through the evacuated space of the bulb from filament to electrode. This current was later found to consist of electrons.
