While much of the research around the eclipse on Monday will focus on the effects of the Sun's brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.
The thirteenth tropical depression of the Eastern Pacific Ocean season formed on Aug. 18. NOAA's GOES-Wet satellite captured an image of the new storm.
A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.
Tropical Storm Harvey is now moving into the eastern Caribbean Sea. NASA's GPM core satellite examined the soaking rainfall the new tropical storm was generating along its path.
Before Hurricane Gert became a post-tropical cyclone, NASA got a look at the rainfall occurring within the storm. After Gert became post-tropical NOAA's GOES-East satellite captured an image as Gert was merging with another system.
Researchers from Predictive Science Inc. used NASA and National Science Foundation-supported supercomputers to run highly-detailed forecasts of the Sun's corona -- the aura of plasma that surrounds the sun -- at the moment of the eclipse. The team combined data from NASA's Solar Dynamics Observatory, magnetic field maps, solar rotation rates and cutting-edge mathematical models to predict the state of the Sun's surface. The simulations are the largest produced by the group and include new physics.
A research team from Predictive Science Inc. (PSI) used the Stampede2 supercomputer at The University of Texas at Austin's Texas Advanced Computing Center (TACC) to forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the US, tracing a 70-mile-wide band across 14 states.
The model focuses mainly on the nature of Fermi bubbles and explains the spectral distribution of the observed cosmic rays flux. It can be said that the processes they described are capable of re-accelerating galactic cosmic rays generated in supernova explosions. Unlike electrons, protons have a significantly greater lifetime, so when accelerated in Fermi bubbles, they can fill up the volume of the Galaxy and be observed near the Earth.
NOAA's GOES-East Satellite spotted potential Tropical Cyclone 9 organizing east of the Lesser Antilles.
NASA's Aqua satellite and NOAA's GOES-East satellite provided an infrared and visible look at Atlantic Hurricane Gert. Both images showed the storm was being affected by wind shear and had become elongated.
