Swift Marks 10 Years of Game-changing Astrophysics
Greenbelt MD (SPX) Nov 24, 2014
Over the past decade, NASA's Swift Gamma-ray Burst Explorer has proven itself to be one of the most versatile astrophysics missions ever flown. It remains the only satellite capable of precisely locating gamma-ray bursts - the universe's most powerful explosions - and monitoring them across a broad range of wavelengths using multiple instruments before they fade from view. "Swift" isn't just a name - it's a core capability, a part of the spacecraft's DNA. Gamma-ray bursts (GRBs) typically last ... read more

Sun's rotating 'magnet' pulls lightning towards UK The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper atmo ... more		How to estimate the magnetic field of an exoplanet? Scientists developed a new method which allows to estimate the magnetic field of a distant exoplanet, i.e., a planet, which is located outside the Solar system and orbits a different star. Moreover, ... more		It's filamentary: How galaxies evolve in the cosmic web How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? An international team of researchers, led by astronomers at the Universi ... more
				The riddle of the missing stars Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are ... more		Scientists get to the heart of fool's gold as a solar material As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into el ... more

Unravelling the mystery of gamma-ray bursts A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'. Researchers at Cardiff University are trying to work out the possible sounds scientists ... more		Spooky alignment of quasars across billions of light-years Quasars are galaxies with very active supermassive black holes at their centres. These black holes are surrounded by spinning discs of extremely hot material that is often spewed out in long jets al ... more		India signs $7 bn deal for 97 domestically made fighter jets France doubles down on threat to build future fighter jet alone US approves $1.2 bn missile sale to Germany		Physicist Helps Discover Subatomic Particles A physicist in the College of Arts and Sciences is the lead contributor to the discovery of two never-before-seen baryonic particles. The finding, which is the subject of a forthcoming article in Ph ... more
				Mystery space object: Black hole or exploding star? For those who grew up on Windows 95, the befuddling new images from Pan-STARRS telescope will likely be instantly recognizable as the click of the spray can on Microsoft Paint. ... more		Two new baryon particles discovered; aligns with York prediction An international team of researchers announced the discovery of two new particles in the baryon family, which makes them cousins of the familiar proton and neutron. The LHCb collaboration at CERN, t ... more

Rosetta continues into its full science phase With the Philae lander's mission complete, Rosetta will now continue its own extraordinary exploration, orbiting Comet 67P/Churymov-Gerasimenko during the coming year as the enigmatic body arcs ever ... more		Researchers Advance 'Quantum Teleportation' The world at the quantum level, at the scale of particles too small for the eye to see, is very strange. It's possible, for instance, to have two particles that are "entangled" - that is, they func ... more		Simulations of Exoplanet Formation May Help Inform Search for Extraterrestrial Life Ancient hot springs reveal how microbes thrived before Earth gained oxygen Framework proposed to study planetary scale impact of life		Swift Probes Exotic Object: Black Hole or Mega Star? An international team of researchers analyzing decades of observations from many facilities, including NASA's Swift satellite, has discovered an unusual source of light in a galaxy some 90 million l ... more
Did Philae Drill The Comet? Philae's Sampling, Drilling and Distribution (SD2) subsystem was activated towards the end of the surface operations that Philae performed on Comet 67P/Churyumov-Gerasimenko last week, despite fears ... more		Gravity may have saved the universe after the Big Bang New research by a team of European physicists could explain why the universe did not collapse immediately after the Big Bang. Studies of the Higgs particle - discovered at CERN in 2012 and responsib ... more		Physicists suggest new way to detect dark matter For years physicists have been looking for the universe's elusive dark matter, but so far no one has seen any trace of it. Maybe we are looking in the wrong place? Now physicists from University of ... more		New model clarifies photoexcited thin-film lattice dynamics A research team from Germany developed an analytical model to describe the structural dynamics of photoexcited thin films and verified it by ultrafast X-ray diffraction. Lattice dynamics, atomic mov ... more

	Schker-blop! The sound of a comet touchdown No trumpet sounded to mark the historic event - instead, it was a hollow, springy plop which heralded last week's landing by the comet probe Philae. ... more		Field-emission plug-and-play solution for microwave electron guns On a quest to design an alternative to the two complex approaches currently used to produce electrons within microwave electron guns, a team of researchers from Euclid TechLabs and Argonne National ... more
