CAST Cern Axion Solar Telescope

KWISP detector searches for dark energy from the Sun Astronomers observe that the universe is expanding at an accelerating rate, but what causes this acceleration is unknown. A form of energy known as dark energy is the most popular explanation, and is keeping scientists the world over occupied searching for it. Now, a team of researchers working with...

Synopsis: Dark Matter Blowing Like a Hurricane The dark matter in our stellar neighborhood may be moving at high speed, which might produce a signature that future dark matter searches could detect.

World’s most powerful X-ray source starts up | CERN Today, an official ceremony marked the inauguration of the European X-ray Free-Electron Laser (European XFEL), in Schenefeld-Hamburg, Germany. Extending over a distance of 3.4 km in tunnels departing from DESY in Bahrenfeld-Hamburg, it will generate ultrashort X-ray flashes at a rate of 27 000 per s...

Enjoy the spectacle!

ATLAS observes direct evidence of light-by-light scattering | CERN Physicists from the ATLAS experiment at CERN have found the first direct evidence ofhigh energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction. The result, published today in Nature Physics, confirms one of the oldest predicti...

CERN CASTs new limits on dark matter | CERN

CERN CASTs new limits on dark matter | CERN In a paper published today in Nature Physics, the CAST experiment at CERN presented new results on the properties of axions – hypothetical particles that would interact very weakly with ordinary matter and therefore could explain the mysterious dark matter that appears to make up most of the matter…

Measurement of Universe's expansion rate creates cosmological puzzle Discrepancy between observations could point to new physics.

Kepler catches the shock breakout of a supernova For the first time, the shock breakout of a supernova has been caught

Did you guess it?

This photo shows a new vacuum chamber in CAST (CERN Axion Solar Telescope) that will soon house a super sensitive force sensor to be used for the first time in an astroparticle physics experiment searching for solar chameleons. Its position is downstream at the focal plane of the CAST X-ray telescope, which tracks the sun during sunrise.

CAST is an experiment that searches for hypothetical particles called “axions” and “chameleons”, as they could explain the mysterious dark matter and dark energy in the Universe.
