What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA's James Webb Space Telescope in Chamber A at NASA's Johnson Space Center in Houston. The photo was used to verify the line of sight (or path light will travel) for the testing configuration.
Satellites have detected powerful solar flares in the last two months, but this phenomenon has been recorded for over a century. On Sept. 10, 1886, at the age of just 17, a young amateur astronomer using a modest telescope observed from Madrid one of these sudden flashes in a sunspot. This is what researchers from the Instituto de Astrofísica de Canarias and the Universidad de Extremadura have recently found.
A hundred years ago, Albert Einstein published his General Relativity theory, predicting the existence of gravitational waves or ripples in space-time, due to violent motion of massive objects in the universe. Collision and merger of two neutron stars should produce gravitational waves and gamma rays simultaneously. Until a few weeks ago, that could not be proven scientifically. Then researchers saw the collision of two neutron stars on Aug. 17, 2017, and everything changed.
On Dec. 8, 2017, NASA launches the Ionospheric Connection Explorer, or ICON, a low-Earth orbiting satellite that will give us new information about how Earth's atmosphere interacts with near-Earth space.
This cosmic event was also observed in visible light and provides an explanation for gamma-ray bursts.
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.
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.
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.
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.
