For the first time, astronomers have observed a celestial event through both conventional telescopes and gravitational waves. The collision of two super-dense neutron stars just 120 million light-years from Earth was captured by both gravity wave observatories (Laser Interferometer Gravitational Observatory, LIGO in the US, and Virgo in Italy) and telescopes including the DLT40 survey based in Chile.
The National Institute of Standards and Technology (NIST) is planning to take new measurements of the Moon's brightness, a highly useful property that satellites rely upon every day.
Astrophysicist Chris Fryer was enjoying an evening with friends on Aug. 25, 2017, when he got the news of a gravitational-wave detection by LIGO, the Laser Interferometer Gravitational-wave Observatory.
Infrared imagery from NASA's Aqua satellite revealed that Tropical Storm Lan was getting stronger as it moved through the Northwestern Pacific Ocean.
For three decades, astronomers thought that only Saturn's moon Janus confined the planet's A ring -- the largest and farthest of the visible rings. But after poring over NASA's Cassini mission data, Cornell astronomers now conclude that the teamwork of seven moons keeps this ring corralled.
Research by planetary scientists at Brown University finds that periodic melting of ice sheets on a cold early Mars would have created enough water to carve the ancient valleys and lakebeds seen on the planet today.
An international research team, including physicists from the Weizmann Institute of Science, has for the first time succeeded in observing a merger of two colliding neutron stars. The merger was simultaneously picked up by three detectors built for this purpose: the two belonging to the Laser Interferometer Gravitational-Wave Observatory, or LIGO, in the United States, and the Virgo detector in Italy.
For the first time in history, Wits researchers have witnessed electromagnetic signals that are associated with the gravitational wave emission from the coalescence of two massive neutron stars.
Scientists around Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna are in search of unique biosignatures, which are left on synthetic extraterrestrial minerals by microbial activity. The biochemist and astrobiologist investigates these signatures at her own miniaturized 'Mars farm' where she can observe interactions between the archaeon Metallosphaera sedula and Mars-like rocks. These microbes are capable of oxidizing and integrating metals into their metabolism.
Central predictions by GSI scientists on the formation of heavy elements such as gold and platinum in the universe have now been observed astrophysically. For the first time gravitational waves of merging neutron stars were detected. This also puts further focus on the future accelerator facility FAIR, as conditions for further research on neutron stars can be simulated there.
