As super typhoon Nepartak NASA satellites are gathering data on wind, temperature, rainfall, and cloud extent. NASA's Terra satellite, the Suomi NPP satellite and the RapidScat instrument have been analyzing the storm.
The RapidScat instrument that flies aboard the International Space Station has been analyzing the winds around Super typhoon Nepartak. RapidScat is a scatterometer that can measure wind speeds over open ocean surfaces. RapidScat passed directly over Super Typhoon Nepartak on July 6 and read wind speeds upwards of 27 meters per second (60.4 mph/97.2 kph).
Tropical Storm force winds of 34 knots (39 mph/63 kph) or higher were occurring within 135 to 145 miles of the center, while typhoon-force winds of 64 knots (74 mph/119 kph) or higher occur within 45 to 60 miles of the center.
On July 7 at 02:30 UTC (July 6 at 10:30 p.m. EDT) the MODIS instrument aboard NASA's Terra satellite captured a visible light image of Super Typhoon Nepartak approaching Taiwan. The image showed a clear eye and bands of thunderstorms wrapping into the low-level center.
On July 7, 2016, at 12:45 a.m. EDT, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA-DOD's Suomi NPP satellite captured a close-up image of the storm's eye surrounded by powerful thunderstorms.
The Joint Typhoon Warning Center (JTWC) said that Nepartak appears to have weakened slightly during the early morning of July 7 (EDT) with cooling eye temperatures evident in infrared satellite data.
The Philippines issued some warnings for July 7: Public storm warning signal #2 is raised in Batanes group of islands and Public storm warning signal #1 is raised in Babuyan group of Islands. In the Philippines Nepartak is referred to as Butchoy.
At 1500 UTC (11 a.m. EDT) on July 7, Nepartak was still a super typhoon. Maximum sustained winds were near 140 knots (161.1 mph/259.3 kph). It was located near 22.0 degrees north latitude and 122.6 degrees east longitude, about 196 nautical miles south-southeast of Taipei, Taiwan. Nepartak was moving to the west-northwest at 8 knots (9.2 mph/14.8 kph).
Taiwan's Central Weather Bureau posted Typhoon Warnings on July 7. For details and graphics visit: http://www.
Nepartak is expected to cross southern Taiwan from southeast to northwest. Landfall is expected around July 8 around 0000 UTC (July 7 at 8 p.m. EDT). Nepartak has started on a weakening trend as it approaches Taiwan. The Joint Typhoon Warning Center expects the storm to move through the Taiwan Straits and make landfall in eastern China around July 9 around 0000 UTC (8 p.m. EDT) where it will dissipate.

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...
