It will take about 11 trillion gallons of water (42 cubic kilometers) — around 1.5 times the maximum volume of the largest U.S. reservoir — to recover from California’s continuing drought, according to a new analysis of NASA satellite data. (more…)
New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built.
The study published in The Astrophysical Journal Letters by UCL cosmologists Dr Andrew Pontzen and Dr Hiranya Peiris (both UCL Physics & Astronomy), together with collaborators at Princeton and Barcelona Universities, shows how forthcoming astronomical surveys will reveal what lit up the cosmos.

One-day conference in Beijing kicks off summer training for graduate students studying socio-economic inequality
A team of scholars who are engaged in researching ways to improve human capital and economic opportunity convened the “Conference on the Study of Inequality” on Monday, June 17, at the University of Chicago Center in Beijing.
The conference, which was co-sponsored by the Human Capital and Economic Opportunity Global Working Group, the University of Chicago Center in Beijing and the China Center for Economic Research at Peking University, kicked off a week of events. (more…)
PASADENA, Calif. – New insights into two factors that are creating a potentially volatile Southern California wildfire season come from an ongoing project using NASA and Indian satellite data by scientists at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.; and Chapman University, Orange, Calif.
The scientists tracked the relationship between rainfall and the growth and drying-out of vegetation in recent months, during an abnormally dry year. They found the timing of rains triggered regional vegetation growth in January and early February, which then dried out faster than normal during a period of low rainfall, strong winds and high temperatures in March and April. The combination likely elevates wildfire risks by increasing available fuel. (more…)
A group of scientists from Hawaiʻi, Brazil and California has measured the diameter of the Sun with unprecedented accuracy by using a spacecraft to time the transits of the planet Mercury across the face of the Sun in 2003 and 2006.
The measurements of the Sun’s size were made by University of Hawaiʻi at Mānoa Institute for Astronomy scientists Drs. Marcelo Emilio (visiting from Ponta Grossa, Brazil), Jeff Kuhn and Isabelle Scholl in collaboration with Dr. Rock Bush of Stanford University. They used the Michelson Doppler Imager (MDI) aboard NASA’s Solar and Heliospheric Observatory (SOHO) to make the measurements. (more…)
