Satellites are keeping an eye on the US and NOAA's GOES East satellite showed two storm systems for pre-Thanksgiving travelers on Wednesday, Nov. 22, 2017. One system was exiting the northeastern US while the other was affecting the Pacific Northwest.
As intense rain storms moved into Jeddah, Saudi Arabia, on Nov. 21, NASA's Global Precipitation Measurement Mission or GPM core satellite analyzed the severe storms.
Neutron stars are made out of cold ultra-dense matter. How this matter behaves is one of the biggest mysteries in modern nuclear physics. Researchers developed a new method for measuring the radius of neutron stars which helps them to understand what happens to the matter inside the star under extreme pressure.
Researchers find that lightning strikes causes photonuclear reactions in the atmosphere, creating antimatter.
For the first time, a science experiment has measured Earth's ability to absorb neutrinos -- the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with the IceCube detector, an array of 5,160 basketball-sized sensors frozen deep within a cubic kilometer of very clear ice near the South Pole.
Researchers have hypothesized that the universe contains a 'dark matter.' They have also posited the existence of a 'dark energy.' These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion of the universe. But -- according to a researcher at UNIGE -- these concepts may be no longer valid: the phenomena can be demonstrated without them. This research exploits a new theoretical model based on the scale invariance of the empty space.
In an analysis of data from an experiment embedded in Antarctic ice, a research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos -- particles that only very rarely interact with matter.
Famously, neutrinos, the nearly massless particles that are a fundamental component of the universe, can zip through a million miles of lead without skipping a beat. Now, in a critical measurement that may one day help predict new physics beyond the Standard Model of particle physics -- the model that seeks to explain the fundamental forces of the universe -- an international team of researchers with the IceCube Neutrino Observatory has shown how energized neutrinos can be stopped cold as they pass through the Earth.
Municipalities, enterprises, and households are switching to LED lights in order to save energy. But these savings might be lost if their neighbors install new or brighter lamps. Scientists fear that this 'rebound effect' might partially or totally cancel out the savings of individual lighting retrofit projects, and make skies over cities considerably brighter.
A research team led by The University of Texas at Austin Jackson School of Geosciences took to the lab to recreate the magmatic melt that once formed the lunar surface and uncovered new insights on how the modern moonscape came to be.
