When NASA's Aqua satellite flew over Tropical Depression 17E at 5:41 a.m. EDT (0951 UTC) on Tuesday, October 30, the Atmospheric Infrared Sounder (AIRS) instrument took an infrared picture of the storm.
The AIRS instrument aboard NASA's Aqua satellite captured this image of Tropical Depression 17 on October 30 at 5:41 a.m. EDT before it intensified into Tropical Storm Rosa. The strongest storms with coldest cloud top temperatures appear in purple. The purple indicates temperatures as cold as -63F (-52C).

The AIRS data showed a large, circular area of very strong convection (rising air that forms thunderstorms that make up a tropical cyclone) around the storm's center. Scientists identify the convection as strong, because the air pushes cloud tops of those thunderstorms to the top of the troposphere where temperatures are as cold as or colder than -63 Fahrenheit (-52 Celsius).
The AIRS data showed that those clouds were near that temperature, indicating they were high in the atmosphere, and when they're that high, they're powerful, and are typically indicative of heavy rainfall.
At 8 a.m. EDT (1500 UTC) the center of Tropical Storm Rosa was located near latitude 14.5 north and longitude 116.5 west. Rosa is moving toward the west-northwest near 7 mph (11 kph) away from the mainland. Rosa is expected to continue in that direction and turn more to the west in the next couple of days. Rosa's estimated minimum central pressure is 1004 millibars.
Rosa's maximum sustained winds were near 40 mph (65 kph) and the National Hurricane Center expects some strengthening later today and October 31 before weakening on November 1.

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.
