Sir Ranulph Fiennes' 'coldest journey' begins Sir Ranulph Fiennes is leading a team of five other explorers in a quest to achieve a feat no other human has managed - to walk across Antarctica in the near permanent darkness and super low temperatures of winter. Phase one of The Coldest Journey expedit...
New Buried Asteroid Impact Crater Discovered in Canada An extraterrestrial impact crater is hiding near a Canadian ghost town. Nearly 5 miles across and 3,000 feet deep, the stealth crater has lurked just west of Bow City, Alberta, for millions of years. Since the 1930s, some had suspected a bit of o...
Pigeons may 'hear' magnetic fields Individual neurons in birds' brains can relay crucial information about Earth's magnetic field, possibly providing the animals with an 'internal GPS', according to research into magnetoreception. Pigeons' remarkable navigational feats have long been pe...

Title: Two distinct phases in the first 13 seconds of GRB110731a prompt emission Authors: Mohammad A. F. Basha In this work, the time-resolved BAT/GBM/LAT joint spectral analysis of GRB110731A during the prompt phase from GBM trigger and up to 13 seconds showed that, at the very early phase of prom...
One of the most mysterious aspects of black holes is their ability to shoot small, steady jets of matter into space near the speed of light. Until the sensitive infrared eyes of NASA's Spitzer Space Telescope recently spotted one of these jets around a nearby neutron star, or super-dense dead star, b...
The Great Smog of '52 or Big Smoke was a severe air pollution event that affected London, England, during December 1952. On 4 December 1952, an anticyclone settled over a windless London, causing a temperature inversion with cold, stagnant air trapped under a layer (or "lid") of warm air...
Joseph Louis Gay-Lussac (6 December 1778 - 9 May 1850) was a French chemist and physicist. He is known mostly for two laws related to gases, and for his work on alcohol-water mixtures, which led to the degrees Gay-Lussac used to measure alcoholic beverages in many countries. Read more
Yoshio Nishina (December 6, 1890 - January 10, 1951) was the founding father of modern physics research in Japan. He co-authored the well-known KleinNishina formula. He was a principal investigator of RIKEN and mentored generations of physicists, including two Nobel Laureates: Hideki Yukawa a...
Title: V1820 Orionis : an RR Lyrae star with strong and irregular Blazhko effect Authors: Pierre de Ponthiere, Franz-Josef Hambsch, Tom Krajci, Kenneth Menzies, Patrick Wils The Blazhko effect in V1820 Orionis and its period were reported for the first time by Wils et al. (2006) from a data analysi...
Thanks to measurements by the D-CIXS X-ray spectrometer, ESA`s SMART-1 spacecraft has made the first ever unambiguous remote-sensing detection of calcium on the Moon.
SMART-1 (Small Missions for Advanced Research in Technology) was launched on 27 September 2003,...
