The “eternal” ice in Antarctica is melting faster than previously assumed, especially … Read more
Launch Summary: Scroll down for live coverage of the launch of a SpaceX Falcon 9 rocket from Space Launch Complex 40 on Tuesday, June 4. Night owls cheered when a SpaceX rocket launch was scheduled for just before 3 a.m. EDT Wednesday in the middle of the night. However, the launch was delayed until 4:55 … Read more
Diagram of H3+ production in Jupiter. Aurora H3+ emission near the magnetic poles is caused by precipitating electrons, and extreme UV radiation from the sun irradiates the day side and dominates H3+ production near the equator. No significant H3+ is expected at low latitudes on the nightside, making it an ideal DM signal area. Credit: … Read more
University of Glasgow Techniques developed to analyze ripples in space-time detected by one of the most sensitive scientific instruments of the 21st century have shed new light on the function of the oldest known analog computer. Astronomers from the University of Glasgow have used statistical modelling techniques developed to analyse gravitational waves to determine the … Read more
A pulsed laser co-propagates with the electron beam through the MLS U125 undulator and imposes an energy modulation. The same undulator serves as a radiator in the subsequent passes of the electron beam. The undulator radiation is detected by a fast photodiode, while the laser pulse is blocked from the detection path using an electro-optical … Read more

Trek has officially launched its brand new version of the Madone. This will be the 8th generation of the bicycle. Trek claims it is as aero as the Gen 7 Madone, but now as light as the Emonda. The new Madone will replace both bikes, so Trek joins the growing number of bike brands that … Read more
A celestial body nicknamed the ‘Blaze Star’ (because it bursts into temporary brightness about every 80 years) is about to live up to its name with a sudden outpouring of light, astronomers say. Officially known as the T Coronae Borealis, or T CrB for short, the Blaze Star is not a single object, but in … Read more
The inside of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider. Rochester physicists working on the detector have observed that the spin entanglement between top quarks and top antiquarks persists at long distances and high speeds.
