NASA-NOAA's Suomi NPP Satellite passed over Typhoon Rammasun early on July 14 and captured a visible image of the storm that showed large bands of thunderstorms wrapping into the center as it approached the central Philippines.
When NASA-NOAA's Suomi NPP satellite passed over Rammasun on July 14 at 04:20 UTC, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard took a visible image of the storm.
The VIIRS instrument showed large, thick bands of powerful thunderstorms wrapping into the low-level center of circulation. The largest band extended from the western to southern and around to the eastern quadrants of the storm before spiraling into the center. Powerful thunderstorms also surrounded the tightly wound eye.
VIIRS collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans. VIIRS flies aboard the Suomi NPP satellite, which is managed by both NASA and NOAA.
Forecasters at the Joint Typhoon Warning Center noted on July 14 that Rammasun had slowed in forward movement and continued to consolidate as convection (rising air that forms the thunderstorms that make up the tropical cyclone) has further strengthened and the storm has developed an irregular eye about 15 nautical miles wide.
Microwave satellite imagery showed the storm had strengthened as the eyewall (the powerful thunderstorms around the open eye) became more developed.
On July 14 at 1500 UTC (11 a.m. EDT), Typhoon Rammasun had maximum sustained winds near 75 knots. Rammasun was moving to the west-southwestward at 10 knots. It was centered near 12.7 north latitude and 127.6 east longitude, about 435 nautical miles southeast of Manila, and closing in on the central Visayas region of the Philippines.
Typhoon Rammasun is expected to make landfall in the eastern Visayas region of the Philippines around July 15 at 0000 UTC (July 14 at 8 p.m. EDT). On July 13, Public storm warning signal #1 was in force in the following Luzon provinces: Camarines Norte & Sur, Catanduanes, Albay and Sorsogon, and Public storm warning signal #1 was in force in the Visayas province of Northern Samar.
The Joint Typhoon Warning Center expects Rammasun to move across the central and northern Philippines in a northwesterly direction crossing near Manila around July 16 at 0000 UTC (July 15 at 8 p.m. EDT), then moving into the South China Sea for another landfall in mainland China, just north of Hainan Island late on July 18 as a typhoon.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
