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).(Credit: NASA)
A time sequence of Hubble Space Telescope images, taken in the 15 years from 1994 to 2009, showing the collision of the expanding supernova remnant with a ring of dense material ejected by the progenitor star 20,000 years before the supernova. (Credit: NASA)
Computational techniques developed by a team from NIST and IU could enable precise computation of atomic properties that are important for nuclear medicine, as well as astrophysics and other fields of atomic research. Image: Paco Ayala (Fotolia)
The Perseus galaxy cluster is one of the most massive objects in the universe, containing thousands of galaxies immersed in a vast cloud of multimillion degree gas. (Credit: NASA)
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.
Monash and Warwick astronomers are searching for gravitational waves emitted by Scorpius X-1.
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.
