SLAC National Accelerator Laboratory 5 Oct 2017, 17:56 UTC Researchers are testing a prototype “radio” that could let them listen to the tune of mysterious dark matter particles.
Square Kilometer Array 5 Oct 2017, 13:25 UTC Organohalogen methyl chloride discovered by ALMA around the infant stars in IRAS 16293-2422. These same organic compounds were discovered in the thin atmosphere surrounding 67P/C-G by the Rosetta space probe. Credit: B. Saxton (NRAO/AUI/NSF). SKA Global Headquarters, Jodrell Bank, UK, Thursday 5 October 2018 – Most people aren’t familiar with methyl chloride, but this complex organic molecule was widely believed to be an indicator of Life if detected on another planet. In a recent study published in Nature, an international team of astronomers led by Edith Fayolle (Harvard-Smithsonian Center for Astrophysics) and including SKA Project Scientist Tyler Bourke detected the molecule around an infant star system, putting this theory into question. The team used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile to make the detection in a dusty & cloudy environment containing several proto-stars of similar mass to the Sun, located about 400 light years from Earth. The molecule was also previously detected in similar abundance by the Rosetta probe around the comet 67P/Churyumov-Gerasimenko. Since comets are remnants of early planetary formation, these new observations support the idea that planetary systems have a similar chemical composition than their parent star-forming regions. “Methyl chloride is usually associated with industrial ...
ESA Top News 5 Oct 2017, 11:22 UTC A bright fireball was spotted over the Netherlands and Belgium on 21 September at 21:00 CEST (19:00 GMT). It was caused by a small meteoroid, estimated to be around several centimetres, entering Earth’s atmosphere and burning up. The fireball was captured by a number of all-sky camera stations of the Dutch–Belgian meteor network operated by amateurs of the Dutch Meteor Society and the Meteor Section of the Royal Netherlands Association for Meteorology and Astronomy. They use automated photographic cameras with fish-eye lenses to capture images of the night sky on clear nights. This remarkable image was captured by one of the stations, at Ermelo, operated by Koen Miskotte. It is a 1.5 minute exposure with a Canon EOS 6D DSLR and a fish-eye lens. The camera lens was equipped with an LCD shutter that, during the exposure, creates brief ‘breaks’ at a rate of 14 per second. These are the dark gaps in the trail making it look dashed. Because the LCD shutter rate is known, you can count the dashes and obtain the duration of the fireball: 5.3 seconds. The image also provides information on the deceleration of the meteoroid in the atmosphere. In this case, it entered the ...
NASA's Jet Propulsion Laboratory News and Features 4 Oct 2017, 18:42 UTC It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side.
Subaru Telescope 4 Oct 2017, 17:00 UTC An international team of researchers has found evidence that the brightest stellar explosions in our Universe could be triggered by helium nuclear detonation near the surface of a white dwarf star. Using Hyper Suprime-Cam mounted on the Subaru Telescope, the team detected a type Ia supernova within a day after the explosion, and explained its behavior through a model calculated using the supercomputer ATERUI.

NASA's Goddard Space Flight Center 4 Oct 2017, 11:53 UTC Scientists will use NASA’s James Webb Space Telescope to study sections of the sky previously observed by NASA’s Great Observatories, including the Hubble Space Telescope and the Spitzer Space Telescope, to understand the creation of the universe’s first galaxies and stars.
NASA's Jet Propulsion Laboratory News and Features 3 Oct 2017, 19:10 UTC The first direct observations of gravitational waves have earned the Nobel Prize in Physics for three key players in the Laser Interferometer Gravitational-Wave Observatory (LIGO) collaboration. Caltech professors emeritus Kip S. Thorne and Barry C. Barish, along with MIT professor emeritus Rainer Weiss, have been named winners of the prize.
