NASA's Atmospheric Infrared Sounder instrument also known as AIRS, flies aboard the Aqua satellite. AIRS uses infrared light and shined that light on Tropical Storm Dorian on July 25 at 03:29 UTC (11:29 p.m. EDT, July 24).
The AIRS instrument aboard NASA's Aqua satellite captured this infrared image of Tropical Storm Dorian on July 25 at 03:29 UTC (11:29 p.m. EDT, July 24). Strongest storms and heaviest rains are around the center and in a band of thunderstorms south of the center with cloud top temperatures near -63F/-52C (purple).

Infrared data helps determine temperature, such as the cloud top and sea surface temperatures. AIRS data revealed that Dorian's strongest storms and heaviest rains were around its center and in a band of thunderstorms south of the center. Those areas had cloud top temperatures near -63F/-52C, indicating very high thunderstorms.
Forecasters at the National Hurricane Center kept a close eye on Dorian over the last 24 hours as it traversed cooler sea surface temperatures, and survived. Dorian is now moving over and toward warmer waters.
The official position of Tropical Storm Dorian at 11 a.m. EDT (1500 UTC), was about 1,800 miles (2,900 km) east of the northern Leeward Islands, near 16.0 north and 35.9 west, according to the National Hurricane Center or NHC. The NHC noted that Dorian's maximum sustained winds were near 60 mph (95 kph) and some fluctuations in intensity are expected in the next couple of days. The tropical-storm-force winds extend outward up to 60 miles (95 km) from the center, making Dorian about 120 miles (190 km) in diameter.
Dorian was moving toward the west-northwest near 17 mph (28 kph) and that general motion is expected to continue today, followed by a gradual turn toward the west on Friday, July 26. The estimated minimum central pressure is 999 millibars.
The NHC expects Dorian to continue to move west-northwest across the Atlantic.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
