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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
