Venus transits the rising Sun

Mirage maker

30 October 2015

Aditya Sadhanala wanders over to the wall, turns a pulley, and a wooden box about a metre squared swings up and away. Below it gleams an array of carefully positioned lasers, deflectors and sensors surrounding a piece of glass no bigger than a contact lens. He flips a switch and creates a ‘mirage’.

Post-16 education must be reformed to tackle damaging arts-science divide

04 September 2015

Why is it acceptable to say “I never could do maths” but not “I’ve never read any Shakespeare”? It’s symptomatic of the art-science divide that can only be addressed by reforming our education system, writes Professor Athene Donald from the Department of Physics and Master of Churchill College.

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 “squeezed” – an achievement which at least one textbook had written off as hopeless.

The central object is a very distant galaxy, labelled BDF 3299. The bright red cloud just to the lower left is the ALMA detection of a vast cloud of material that is in the process of assembling the very young galaxy

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

22 July 2015

An international team of astronomers led by the University of Cambridge have detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe – less than one billion years after the Big Bang. The 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.
