When NASA's Aqua satellite passed over the Northern Indian Ocean, it captured an infrared image that revealed Tropical Cyclone Vayu was elongating. That's never a good sign for a tropical cyclone, because they need a circular rotation to maintain strength.
NASA's Terra satellite showed Tropical Cyclone Vayu still lingering near the northwestern coast of India, and its cloud-filled eye remained offshore.
Researchers at the University of Iowa and the United States Geologic Survey report data gathered by orbiting satellites can yield more information about destructive earthquakes and can improve aid and humanitarian response efforts. The researchers looked at satellite data from several recent, large-magnitude earthquakes.
When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous -- so much so that it forms what looks like an especially bright new star that slowly fades away over time.
Tropical Cyclone Vayu's eye was just off the western coast of India when the NOAA-20 satellite passed overhead and captured a visible image of the storm.
Based on preliminary results from a new Gemini Observatory survey of 531 stars with the Gemini Planet Imager (GPI), it appears more and more likely that large planets and brown dwarfs have very different roots.
For 10 years, NASA's Fermi Gamma-ray Space Telescope has scanned the sky for gamma-ray bursts (GRBs), the universe's most luminous explosions. A new catalog of the highest-energy blasts provides scientists with fresh insights into how they work.
New research by a University of Guelph physicist suggests most of Earth's heavy metals were spewed from a largely overlooked kind of star explosion called a collapsar.
Nestled within this field of bright foreground stars lies ESO 495-21, a tiny galaxy with a big heart. ESO 495-21 may be just 3000 light-years across, but that is not stopping the galaxy from furiously forming huge numbers of stars. It may also host a supermassive black hole; this is unusual for a galaxy of its size, and may provide intriguing hints as to how galaxies form and evolve.
A new study from The University of Texas Medical Branch at Galveston has further documented how muscles are affected by reduced gravity conditions during space flight missions and uncovered how exercise and hormone treatments can be tailored to minimize muscle loss for individual space travelers.
