On August 31, at 0900 UTC (5 a.m. EDT), Typhoon Kompasu had maximum sustained winds near 109 mph and is 45 nm east-southeast of Kadena AB, Japan. The cyclone will track over Okinawa within the next few hours and continue on a northwestward track for the next 12 to 24 hours, then cross the Korean Peninsula (from western to eastern Korea) into the Sea of Japan, cross northern Japan and exit into the Northwestern Pacific Ocean by September 4.
When the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies on Terra captured the image of all three storms the center of circulation was apparent in Tropical Storm Namtheun, and the eye was visible in Typhoon Kompasu, although some high clouds were filling in the center.
At 1 a.m. EDT, Kadena Air Base wasn't reporting tropical storm force winds from Typhoon Kompasu yet. Kadena Air Base is a United States Air Force base located in the towns of Kadena and Chatan and the city of Okinawa, in Okinawa Prefecture, Japan. Kadena Air Base is the hub of U.S. airpower in the Pacific, and home to the USAF's 18th Wing and a variety of associate units. Kadena Air Base did report, however, that sea level pressure dropped and amazing 44 millibars in less than 2 hours, indicating the Typhoon was approaching.
After impacting Kadena Air Base, Typhoon Kompasu is expected to turn north, then northeast and track over the Korean Peninsula and into the Sea of Japan
The other two tropical cyclones, Tropical Storm Lionrock and Tropical Storm Namtheun, are forecast to merge in the next day or two. NASA satellite data show that the two storms are in close proximity of each other. On August 31 at 0900 UTC (5 a.m. EDT), Tropical Storm Lionrock, formerly Tropical Depression 07W, had maximum sustained winds near 57 mph. It was located about 195 nm southwest of Kaohsiung, Taiwan and it is forecast to merge with Tropical Storm Namtheun (formerly Tropical Depression 09W). Lionrock has moved east-northeastward at 2 mph. Infrared satellite imagery, such as that from the Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite was showing a decrease in convection in the storm's center. By mid-day (Eastern Time) on Thursday, Lionrock should make the merge with Namtheun and turn northwestward. It is expected to make landfall in eastern China late on Thursday, September 2 and dissipate.
On August 31 at 0900 UTC (5 a.m. EDT) Namtheun was about 80 nautical miles west of Taipei, Taiwan and moving west-southwestward at 8 mph. Its winds were sustained near 39 mph, so it was just at the threshold for being a tropical storm. The storm's low level center is partially exposed because of an upper level trough (elongated area of low pressure) to its north causing wind shear. Despite this, Namtheun is expected to remain the dominant circulation when it merges with Lionrock.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
