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).[

Einsteins biggest blunder? The 25-year-old supernova that could change the speed of light forever

Supermassive black hole trio discovered

Two closely orbiting black holes in a galaxy about 4.2 billion light-years from Earth emit wavy jets, seen as a bluish spiral, while the third black hole in the trio is more distant, emitting linear jets off to the right.

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.

Swiftly Moving Gas Streamer Eclipses Supermassive Black Hole

This is an illustration of the physical, spatial and temporal picture for the outflows emanating from the vicinity of the super massive black hole in the galaxy NGC 5548. The behavior of the emission source in five epochs is shown along the time axis. The obscurer is situated at roughly 0.03 light years (0.01 parsecs) from the emission source and is only seen in 2011 and 2013 (it is much stronger in 2013). Outflow component 1 shows the most dramatic changes in its absorption troughs. Different observed ionic species are represented as colored zones within the absorbers.
