Tropical Cyclone Nathan moved from Queensland, Australia west across the Gulf Carpentaria and is now crossing The Top End. NASA's Aqua and Terra satellite provided a day-to-day look at Nathan's western journey.
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument flies aboard two NASA satellites: Terra and Aqua. MODIS provided images from each of those satellites over the course of three days that showed Nathan's western movement and second landfall in the Northern Territory of Australia.
On Saturday, March 21 at 04:50 UTC (12:50 a.m. EDT) MODIS aboard NASA's Aqua satellite captured Tropical Cyclone Nathan moving west through the Gulf of Carpentaria. On March 22 at 01:05 UTC (March 21 at 9:05 p.m. EDT) the MODIS instrument aboard NASA's Terra satellite saw Tropical Cyclone Nathan making landfall near Arnheim Land, in the Northern Territory of Australia.
On March 23 at 04:35 UTC (12:35 a.m. EDT), the MODIS instrument aboard NASA's Aqua satellite captured a visible mage of Tropical Cyclone Nathan over the Top End of the Northern Territory, Australia. The Top End of northern Australia is the northernmost section of the Northern Territory.
At 09:00 UTC (5 a.m. EDT), Nathan's maximum sustained winds were near 65 knots (75 mph/120.4 kph), making it a category one hurricane. Nathan's center was located near 11.4 south and 134.1 east, about 210 nautical miles (241 miles/389 km) east-northeast of Darwin, Australia. Nathan was moving west at 6 knots (7 mph/11 kph).
On March 23, the Australian Bureau of Meteorology has posted Warnings and watches for the Northern Territory. The Tropical Cyclone Warning is in effect from Milingimbi to Cape Don and Point Stuart, including Croker Island, Goulburn Island, Gunbalanya, Jabiru and Maningrida. A Tropical Cyclone Watch is in effect from Cape Hotham to Point Stuart and Cape Don to Milikapiti and eastern Melville Island. For updated conditions, watches and warnings, visit: http://www.
The Joint Typhoon Warning Center using animated enhanced infrared satellite imagery, noted that Nathan had maintained overall convective signature as it drifted just offshore of the Northern Territory.
Nathan is tracking along the northern edge of a deep-layered subtropical ridge (elongated area of high pressure) to the south, over central Australia. Later on March 23, the ridge will weaken as a mid-latitude trough (elongated area) of low pressure from the southwest approaches, causing Nathan to move southwestward toward Darwin before returning on a westward track.
The Joint Typhoon Warning Center (JTWC) expects Nathan to continue tracking to the west over the next several days. JTWC's forecast track takes the center of Nathan just south of Darwin on March 25 around 0600 UTC (2 a.m. EDT) on its way into the Southern Indian Ocean.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
