Because Hurricane Igor is a large storm and even if Igor doesn't make a direct landfall in Bermuda, the extent of the winds (the wind field) is so large that the National Hurricane Center noted that Bermuda can be buffeted by winds of hurricane-force or tropical storm-force on its current track.
This image of Hurricane Igor was captured from the Moderate Resolution Imaging Spectroradiometer (MODIS) Instrument that flies aboard NASA\'s Terra satellite at 1420 UTC (10:20 a.m. EDT) on Sept. 14. The storm is 550 miles and would take 10 hours to \"drive across.\"

Maximum sustained winds this morning were near 145 mph, and although the hurricane-force winds extend outward from the center up to 45 miles (90 miles in diameter), tropical-storm-force winds extend as far as 225 miles (550 miles in diameter). Igor is expected to be close to Bermuda within the next 3 to 4 days.
Hurricane Igor was captured in one image from the Moderate Resolution Imaging Spectroradiometer (MODIS) Instrument that flies aboard NASA's Terra satellite at 1420 UTC (10:20 a.m. EDT) on Sept. 14. The image showed the massive extent of Igor's cloud cover, stretching over 500 miles. The image also showed that Igor's eye was covered with high clouds.
At 5 a.m. EDT on Sept. 15, infrared imagery from NASA's Atmospheric Infrared Sounder (AIRS) instrument indicated that the cloud tops had warmed over the western part of the center, and that Igor's eye had cooled. That indicates slight weakening, because higher, colder cloud tops indicate strong convection (rapidly rising air that forms the thunderstorms that power Igor) and when they warm that means that convection has waned. Infrared imagery from AIRS on Sept. 14 at 1723 UTC (1:23 p.m. EDT) continued to show strong convective activity in his center as indicated by high thunderstorms that were as cold as -63F. Since that time, cloud tops have warmed.
At 0352 UTC this morning (11:52 p.m. EDT Sept. 14) NASA's Tropical Rainfall Measuring Mission satellite showed that the southwestern part of the eyewall has eroded, further confirming the weakening that the infrared data showed. However, the National Hurricane Center noted that Igor is still in a good environment for strengthening.
On Sept. 15 at 5 a.m. EDT, Hurricane Igor was still a powerful Category 4 hurricane on the Saffir-Simpson scale with maximum sustained winds of 145 mph. It was about 1,090 miles southeast of Bermuda, near 19.5 North and 54.5 West. Igor was moving west-northwest near 10 mph and had a minimum central pressure of 935 millibars.
Igor is expected to run into southerly wind shear in 3 to 4 days, which may cause some weakening. NASA satellites will watch for those signs as Igor continues moving through the Atlantic Ocean this week.

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.
