As Eastern Pacific Ocean's Tropical Storm Flossie continues to move further west toward Hawaii, NASA's TRMM satellite analyzed its rainfall.

Complicated statistical behaviour observed in complex systems such as early universe can often be understood if it is broken down into simpler ones. Two physicists, Petr Jizba (currently affiliated with the Czech Technical University in Prague), and Fabio Scardigli (now working at Kyoto University in Japan), have just published results in EPJ C pertaining to theoretical predictions of such cosmological systems' dynamics.
Approaching the sun, Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders.
Scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe called the Van Allen radiation belts. Scientists knew that something in space accelerated particles in the radiation belts to more than 99 percent the speed of light but they didn't know what that something was. New results from NASA's Van Allen Probes now show that the acceleration energy comes from within the belts themselves.
The moment when a telescope first opens its doors represents the culmination of years of work and planning -- while simultaneously laying the groundwork for a wealth of research and answers yet to come. It is a moment of excitement and perhaps even a little uncertainty. On July 17, 2013, the international team of scientists and engineers who supported and built NASA's Interface Region Imaging Spectrograph, or IRIS, all lived through that moment.
Two University of Iowa researchers and their colleagues have advanced scientists' knowledge of the Earth's Van Allen radiation belts by answering a long-standing question about the belts.
Craig Kletzing and William Kurth of the UI Department of Physics and Astronomy note that since 1958 when UI space physicist James Van Allen discovered the doughnut-shaped bands of intense radiation encircling the Earth, scientists have wondered just how and where electrons trapped within the belts get their ultra-high energies.

BOZEMAN, Mont. – Scientists can learn a tremendous amount about neutron stars and quark stars without understanding their internal structure in detail, according to two Montana State University scientists who published their findings in the July 26 issue of "Science."
"The stars could be the softest or the hardest in their kind, and it wouldn't matter," said Nicolas Yunes, assistant professor in MSU's Department of Physics.
LOS ALAMOS, N.M., July 25, 2013 — Researchers believe they have solved a lingering mystery about how electrons within Earth's radiation belt can suddenly become energetic enough to kill orbiting satellites. Thanks to data gathered from an intrepid pair of NASA probes roaming the harsh space environment within the Van Allen radiation belts, scientists have identified an internal electron accelerator operating within the belts.
Northern Australia's bushfire season was well underway by the beginning of July, 2013. On July 23 the Aqua satellite flew over the region, allowing the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument flying aboard to capture this true-color image of the winter's fires.
The newest tropical storm to form in the Atlantic was put in NASA's "infrared spotlight." NASA's AIRS instrument uses infrared imaging to analyze tropical cyclones and captured an image of newborn Tropical Storm Dorian.
Tropical Storm Flossie formed in the Eastern Pacific Ocean and strengthened quickly on July 25. NASA's Aqua satellite passed over Flossie and captured an infrared look at the storm and saw a large area of powerful thunderstorms around its center and south of the center.
