Scientists "squeeze" light one particle at a time

01 September 2015

A team of scientists have measured a bizarre effect in quantum physics, in which individual particles of light are said to have been 鈥渟queezed鈥 鈥 an achievement which at least one textbook had written off as hopeless.

Astronomers witness assembly of galaxies in the early Universe for the first time

22 July 2015

An international team of astronomers led by the 探花直播 of Cambridge have detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe 鈥 less than one billion years after the Big Bang. 探花直播new observations will allow astronomers to start to see how the first galaxies were built up and how they cleared the cosmic fog during the era of reionisation. This is the first time that such galaxies have been seen as more than just faint blobs.

Astronomers find first evidence of changing conditions on a super Earth

05 May 2015

Astronomers have detected wildly changing temperatures on a super Earth 鈥 the first time any atmospheric variability has been observed on a rocky planet outside the solar system 鈥 and believe it could be due to huge amounts of volcanic activity, further adding to the mystery of what had been nicknamed the 鈥榙iamond planet鈥.

Large Hadron Collider restarts after two years

07 April 2015

After two years of intense maintenance and consolidation, and several months of preparation for restart, the Large Hadron Collider, the most powerful particle accelerator in the world, is back in operation after a major upgrade.
