Tropical Cyclone Ita has been strengthening over the last two days and by April 10, Ita had become a major hurricane in the Coral Sea when NASA's Terra satellite passed overhead.
Ita's maximum sustained winds were near 115 knots/132 mph/213 kph on April 10 at 0900 UTV/5 a.m. EDT, making it a Category Four hurricane on the Saffir-Simpson scale. According to NOAA, the definition of a Category 4 storm affecting land is: "Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls.
Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months."
Ita's center was still at sea, centered near 12.5 south and 147.1 east, about 275 nautical miles north-northeast of Cairns, Australia. Ita was moving to the north-northeast at 9 knots/10/3 mph/16.6 kph and generating 30-foot/9.1 meter high waves.
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible image of Tropical Cyclone Ita approaching Australia on April 10 at 00:25 UTC. The image showed a cloud-shrouded eye with a thick band of powerful thunderstorms around the center of circulation.
On April 9, Ita was seen twice by NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission satellite known as TRMM satellite. Ita's wind speeds increased from 65 knots/75 mph with TRMM's first flight overhead at 0536 UTC/1:36 a.m. EDT to 80 knots/92 mph when viewed again at 1528 UTC/11:28 p.m. EDT.
TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments captured data on Tropical Cyclone Ita's rainfall at 1528 UTC/11:28 a.m. EDT. TRMM PR data showed that a maximum rainfall rate of almost 163 mm/6.4 inches per hour was located in the eastern side of Ita's eye wall.
TRMM's Precipitation Radar (PR) instrument sliced through Ita's eye and those data were used to create a 3-D "cut-a-way" view. The image showed that powerful storms in Ita's eye wall reached heights of over 14 km/8.7 miles. The tallest thunderstorm towers reached heights of over 16 km/9.9 miles high in a feeder band well to the northeast of Ita's eye.
Ita is continuing to intensify as it moves west, south of Papua New Guinea. The Joint Typhoon Warning Center or JTWC expects the system to peak at 135 knots/155 mph/250 kph on approach to Queensland. JTWC also expects the system will veer sharply southeast on approach to the Australian coastline, and gradually weaken as it passes along the eastern coastline of Queensland. Ita will commence extra-tropical transitioning north of Brisbane.
Current warnings in Queensland are in effect between Lockhart River and Innisfail, extending inland to Kalinga, Laura, Mareeba and Chillagoe. A tropical cyclone watch is in force between Innisfail to Cardwell, extending inland.

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
