NASA's Aqua satellite passed over Typhoon Prapiroon on Oct. 10 at 0435 UTC (12:35 a.m. EDT) and captured a visible image of the storm. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument was able to get a visible image of the typhoon, because it was 1:35 p.m. local Asia/Tokyo time (and night time on the U.S. East coast at 12:35 a.m. EDT).

The MODIS imagery revealed a well-defined center with tightly curved bands of thunderstorms wrapping into the low-level center of the storm. That's the mark of a strong storm. Although Prapiroon's eye was not apparent in the visible MODIS image, it was in microwave imagery from another satellite instrument.
Typhoon Prapiroon's maximum sustained winds were near 90 knots (103.6 mph/166.7 kph) on Wed. Oct. 10 at 1500 UTC (11 a.m. EDT or 12 a.m. on Thurs. Oct. 11 Asia/Tokyo Time). Prapiroon's center was located about 470 nautical miles (541 miles/870.4 km) south-southeast of Kadena Air Base, Okinawa, Japan, near 19.0 North and 129.6 East. The typhoon had already turned and was moving to the west-northwest at 7 knots (8 mph/12.9 kph).
Prapiroon made the U-turn because of a strong area of elongated high pressure called a ridge that is located south of Japan. The storm is moving around the southwestern edge of the high pressure area. Over the next several days, the storm is expected to intensify because it's in an area of low wind shear and warm waters.Text credit: Rob Gutro

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
