Tropical Depression 30W formed in the northwestern Pacific Ocean basin and crossed into the Northern Indian Ocean from Nov. 8 to Nov. 10. By Nov. 12, NASA satellite imagery saw the ex-tropical depression coming back together.

On Nov. 10 at 03:30 UTC/Nov. 9 at 10:30 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite showed the center of Typhoon Haiyan was just south of Hainan Island, China in the South China Sea. Later in the day, Haiyan moved north of Hainan Island and headed for a landfall in extreme northeastern Vietnam. Haiyan's maximum sustained winds were near 75 knots/86 mph/138.9 kph. At 1500 UTC/10 a.m. EDT on Nov. 10.
TORONTO, ON — Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.
Philadelphia – In order to evoke a true transformation, the U.S. health care system needs an audacious goal, one equivalent to President Kennedy's call for a man on the moon in 1962, says Ezekiel J. Emanuel, MD, PHD, Diane v.S. Levy and Robert M. Levy University Professor and chair of the Department of Medical Ethics and Health Policy at the University of Pennsylvania. In a Viewpoint published in the November 13 issue of the Journal of the American Medical Association, Emanuel recommends limiting the rate of per capita health care cost increases to that of the U.S.
The study helps to confirm the idea that the surface of Phobos contains tons of dust, soil, and rock blown off the Martian surface by large projectile impacts. Phobos' orbital path plows through occasional plumes of Martian debris, meaning the tiny moon has been gathering Martian castoffs for millions of years. That means a sample-return mission planned by the Russian space agency could sample two celestial bodies for the price of one.
Foams fascinate, partly due to their short lifespan. Foams change as fluid drains out of their structure over time. It is precisely their ephemeral nature which has, until now, prevented scientists from experimentally probing their characteristic dynamics further. Instead, foams have often been studied theoretically. Now, Nathan Isert from the University of Konstanz, Germany and colleagues, have devised a method of keeping foams in shape using a magnet, which allows their dynamics to be investigated experimentally, as recently described in EPJ E.
The sun emitted its sixth significant flare since Oct. 23, 2013, peaking at 11:26 p.m. EST on Nov. 7, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

Supernovae are intensely bright objects. They are formed when a star reaches the end of its life with a dramatic explosion, expelling most of its material out into space.
The subject of this new Hubble image, spiral galaxy NGC 6984, played host to one of these explosions back in 2012, known as SN 2012im. Now, another star has exploded, forming supernova SN 2013ek — visible in this image as the prominent, star-like bright object just slightly above and to the right of the galaxy's center.
NASA's Tropical Rainfall Measuring Mission or TRMM satellite captured an image of Haiyan just as it was crossing the island of Leyte in the central Philippines. Data was taken at 00:19 UTC (8:19 a.m. local) November 8, 2013 and showed the horizontal distribution of rain intensity within the Haiyan. Rain rates in the center of the swath were generated from the TRMM Precipitation Radar (PR), and those in the outer swath were from the TRMM Microwave Imager (TMI). The data was put together at NASA's Goddard Space Flight Center in Greenbelt, Md.
Now a remnant low pressure area, former Tropical Depression 30W may get new another life in another ocean. NASA's Aqua satellite captured an infrared image of the storm that showed strong circulation and persistent developing thunderstorms around its center.
Tropical Depression 30W moved through the Northwestern Pacific Ocean basin over the Philippines, past Vietnam and on Nov. 8, was entering the Andaman Sea, located in the eastern North Indian Ocean.
Super-Typhoon Haiyan slammed into the eastern Philippines as the strongest tropical cyclone of the year, and today, Nov. 8, is exiting the country and moving into the South China Sea. NASA's Aqua satellite captured visible and infrared data of Hiayan after it made landfall near Leyete, identifying the extent of its power.
Narrow stripes of dirt and rock beneath massive Antarctic glaciers create friction zones that slow the flow of ice toward the sea, researchers at Princeton University and the British Antarctic Survey have found. Understanding how these high-friction regions form and subside could help researchers understand how the flow of these glaciers responds to a warming climate.
RICHLAND, Wash. – Basic ocean conditions such as current directions and water temperature play a huge role in determining the behavior of young migrating salmon as they move from rivers and hit ocean waters for the first time, according to new research. The findings inform restoration policies and practices focused on boosting endangered salmon species in the Pacific Northwest.
Changes in solar activity have contributed no more than 10 per cent to global warming in the twentieth century, a new study has found.
The findings, made by Professor Terry Sloan at the University of Lancaster and Professor Sir Arnold Wolfendale at the University of Durham, find that neither changes in the activity of the Sun, nor its impact in blocking cosmic rays, can be a significant contributor to global warming.
The results have been published today, 8 November, in IOP Publishing's journal Environmental Research Letters.
Astronomers viewing our solar system's asteroid belt with NASA's Hubble Space Telescope have seen for the first time an asteroid with six comet-like tails of dust radiating from it like spokes on a wheel.
Unlike all other known asteroids, which appear simply as tiny points of light, this asteroid, designated P/2013 P5, resembles a rotating lawn sprinkler. Astronomers are puzzled over the asteroid's unusual appearance.
