Due to a scarcity of data, most global estimates of ocean warming start only in the 1950s. However, a team of scientists at the University of Oxford has now succeeded in reconstructing ocean temperature change from 1871 to 2017.

Over the past century, increased greenhouse gas emissions have given rise to an excess of energy in the Earth system. More than 90% of this excess energy has been absorbed by the ocean, leading to increased ocean temperatures and associated sea level rise, while moderating surface warming.

The Royal Astronomical Society has given the Galaxy Zoo team – including the volunteers who have made the project the success it is – their Group Achievement Award for 2019.

Microgeneration is the generation of power on a small scale – for individual homes, communities or in emergency situations. Microgeneration is also important if you are on the move and isolated from the grid e.g. while boating or in a recreational vehicle. the move – for boats or recreational vehicles. The Oxford Microgeneration System converts mechanical energy from wind, water or any other means into electrical power.

The HARMONI instrument for the Extremely Large Telescope has completed a major milestone today, having successfully passed its Preliminary Design Review. The spectrograph, equipped with an integral field capability, observes an astronomical target in 4000 different colours (wavelengths) simultaneously. The project is an international collaboration of several universities, institutes and national laboratories, located in the UK, France and Spain.
