NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.
A decade ago, spurred by a question for a fifth-grade science project, physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago. Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background, Cramer has produced new recordings that fill in higher frequencies to create a fuller and richer sound.
University of Washington researchers and scientists at a Redmond-based space-propulsion company are building components of a fusion-powered rocket aimed to clear many of the hurdles that block deep space travel, including long times in transit, exorbitant costs and health risks.
An instrument that will measure the composition of Mars' upper atmosphere has been integrated into NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. MAVEN has a scheduled launch date of Nov. 18.
The first published results from the Alpha Magnetic Spectrometer (AMS), a major physics experiment operating on the International Space Station, were announced today by the AMS collaboration spokesman, Nobel Laureate Samuel Ting. The result is the most precise measurement to date of the ratio of positrons to electrons in cosmic rays. Measurements of this key ratio may eventually provide the world with our first glimpse into dark matter.
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. In fact, it was so bright that many navigators used this object to make their way across the oceans. A new composite image from three NASA telescopes - Chandra, Hubble, and Spitzer - shows this galaxy like Ferdinand Magellan, who lends his name to the SMC, could never have imagined.
As the universe expands, it is continually subjected to energy shifts, or 'quantum fluctuations', that send out little pulses of 'sound' into the fabric of spacetime. In fact, the universe is thought to have sprung from just such an energy shift. Scientists reports a new mathematical tool that should allow one to use these sounds to help reveal the shape of the universe.
The conference brings together world experts on subjects related to planetary defense, including what we currently know about potentially threatening asteroids and comets, techniques that might be used to deflect a threatening object, and political and policy issues that might affect a decision to take action.
Astronomers from the University of Maryland at College Park (UMCP) and Lowell Observatory have used NASA's Swift satellite to check out comet C/2012 S1 (ISON), which may become one of the most dazzling in decades when it rounds the sun later this year.
