NOAA's GOES-14 satellite captured a visible image of Tropical Storm Rafael in the Atlantic on Oct. 16 at 7:45 a.m. EDT. The image shows the extent of Hurricane Rafael, which is over 410 miles in diameter.

That's longer than the distance between Boston and Washington, D.C. The visible image also showed a thick row of clouds northwest of Rafael. Those clouds are associated with a cold front that just moved off the U.S. east coast and they will play a role in pushing Rafael to the east and draw Rafael into the front.
Infrared satellite data also revealed that the coldest cloud top temperatures (indicating the highest cloud tops and strongest thunderstorms) shifted west of Rafael's center. Those strongest thunderstorms and coldest cloud tops appear as the brightest white area of clouds in the storm on the GOES-14 image.
GOES-14 is operated by NOAA, and the image was created by the NASA GOES Project at NASA's Goddard Space Flight Center, Greenbelt, Md.
A tropical storm warning is in effect for Bermuda today, Oct. 16. The National Hurricane Center (NHC) expects that Bermuda will see between 2 and 4 inches of rainfall and tropical-storm-force winds. NHC expects the center of Rafael to pass east of Bermuda by this evening. Rafael will continue generating rough surf in Bermuda, eastern-facing beaches of the Bahamas and portions of the United States east coast during the next couple of days.
At 8 a.m. EDT on Oct. 16, Rafael's center was near latitude 27.3 north and longitude 65.0 west. Rafael was moving toward the north-northeast near 16 mph (26 kph) and is forecast to turn toward the northeast later on Oct. 16. Rafael's maximum sustained winds were near 85 mph (140 kph), making the storm a category one hurricane on the Saffir-Simpson Hurricane wind scale.
According to the NHC discussion, Rafael is expected to be over much colder water and merge with the strong cold front seen in the GOES-14 satellite image from today, Oct. 16. The merging of systems should cause Rafael to transition into a large and powerful extra-tropical low that will move eastward over the far north Atlantic.

Climate change: In their old age, trees still accumulate large quantities of carbon

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
