The eighth tropical depression of the Eastern Pacific Ocean hurricane season formed far from land as the Global Precipitation Measurement (GPM) core satellite passed overhead and measured rainfall and cloud heights.
This week in the journal Review of Scientific Instruments, from AIP Publishing, the group describes developing and launching their imager, which centers on 'Lobster-Eye optics,' as well as its capabilities and future applications in space exploration.
Researchers from the University of Maryland have come up with a new definition of chaos that applies more broadly than Lyapunov exponents and other previous definitions of chaos. The new definition fits on a few lines, can be easily approximated by numerical methods, and works for a wide variety of chaotic systems.
Geologist James Kennett and colleagues narrow the date of an anomalous cooling event most likely triggered by a cosmic impact.
Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they have a clearer snapshot of how it happens.
New research using NASA satellite data and ocean biology models suggests tiny organisms in vast stretches of the Southern Ocean play a significant role in generating brighter clouds overhead. Brighter clouds reflect more sunlight back into space affecting the amount of solar energy that reaches Earth's surface, which in turn has implications for global climate. The results were published July 17 in the journal Science Advances.
The storm intensified into a tropical storm as NASA's Terra satellite passed overhead at 03:00 UTC (July 22 at 11 p.m. EDT).
NASA's Terra satellite passed over the Eastern Pacific Ocean and observed Tropical Depression Felicia almost directly over Socorro Island, as if the storm swallowed the island.
The Global Precipitation Measurement mission core observatory passed over Typhoon Halola and saw that the northern side of the storm lacked rainfall. Dry air moving into the storm from the north was sapping the development of thunderstorms on that side of the storm.
Today an international team of astronomers from NASA's Kepler mission have announced the discovery of a near-Earth-sized planet in the habitable zone of a Sun-like star. Dr. Daniel Huber from the University of Sydney's School of Physics is part of the team which made the discovery with NASA's Kepler Space Telescope.
