MODIS stands for the Moderate Resolution Imaging Spectroradiometer. Terra's MODIS and Aqua's MODIS view the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths.

NASA's Aqua satellite flew over Hurricane Miriam on Sept. 24 at 21:00 UTC and the MODIS instrument captured a visible image of Hurricane Miriam off Mexico's west coast.
The MODIS image showed that Miriam's eye was covered by high clouds, yet the eye is still about 30 nautical miles wide. Cloud top temperatures around the eye have cooled in infrared imagery, which indicates thunderstorms around the eye still have strong uplift and are shooting high into the troposphere.
On Sept. 25 at 5 a.m. EDT Hurricane Miriam's maximum sustained winds were near 105 mph (165 kmh), making it a category 2 hurricane on the Saffir-Simpson hurricane scale. Miriam 's hurricane-force winds extend only 30 miles (45 km) from the center. Slow weakening is forecast during the next 48 hours, according to the National Hurricane Center.
Miriam's center was located near latitude 18.7 north and longitude 114.3 west. Miriam is moving in a northwesterly direction near 6 mph (9 kmh) and is expected to turn to the north-northwest later on Sept. 25, followed by a turn to the north. Miriam's estimated minimum central pressure is 968 millibars.
Although Miriam is off-shore, the hurricane is producing very rough seas along the south and western coasts of the central Baja Peninsula, and those conditions will continue for the next several days.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
