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.
Astrophysicists at the University of Texas at Arlington have predicted that an Earth-like planet may be lurking in a star system just 16 light years away. The team investigated the star system Gliese 832 for additional exoplanets residing between the two currently known alien worlds in this system. Their computations revealed that an additional Earth-like planet with a dynamically stable configuration may be residing at a distance ranging from 0.25 to 2.0 astronomical unit (AU) from the star.
When astronauts travel in space they can't see or even feel radiation. However, NASA's Human Research Program (HRP) is studying the effects radiation plays on the human body and developing ways to monitor and protect against this silent hazard.
Astronomers have identified a white dwarf star in our galaxy that may be the leftover remains of a recently discovered type of supernova.
NASA's Terra satellite captured an infrared image of Typhoon Banyan that showed the strongest storms were being pushed northeast of the center from wind shear.
