Satellite imagery from NASA's Aqua and Terra satellites have shown that Jova's eye was only sometimes visible and other times appeared cloud covered, making it appear as Jova "winking." Other satellites, such as NOAA's GOES-11 satellite captured Jova's "winks."
The visible image of Hurricane Jova on the left was taken from the MODIS instrument on NASA's Terra satellite on Oct. 10 at 1:40 p.m. EDT. Jova's extreme northeastern clouds are already over western Mexico, and the eye is clearly visible. On the right, a visible image from the GOES-11 satellite on Oct. 11 at 12:45 p.m. EDT shows Jova's eye "closed." Credit: Credit: NASA Goddard/MODIS Rapid Response Team/ NASA-NOAA GOES Project
In a visible image of Hurricane Jova from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra satellite on Oct. 10 at 1:40 p.m. EDT, the eye was clearly visible. A visible image from NOAA's GOES-11 satellite on Oct. 11 at 12:45 p.m. EDT showed Jova's eye "closed" (or cloud-filled). The NASA GOES Project and the MODIS Rapid Response Teams are both located at NASA's Goddard Space Flight Center, and processed those images.
In addition to Jova's wink, the infrared AIRS instrument on NASA's Aqua satellite got a cold stare from Jova's eye. Infrared data measures cloud top temperatures, and NASA AIRS instrument noticed they were as cold as -80 Celsius (-112 Fahrenheit) in the thunderstorms in Jova's eyewall. Those frigid cloud top temperatures indicate there's a tremendous amount of power in the storm. The colder the cloud tops, the higher and stronger they are- and Jova is very powerful.
Today, dangerous Hurricane Jova continues to slowly approach the southwestern coast of Mexico today. At 11 a.m. EDT today, Oct. 11, it was near 17.8 North and 105.6 West. That's about 120 miles (190 km) southwest of Manzanillo, Mexico, and 180 miles (290 km) south of Cabo Corrientes. Jova's maximum sustained winds were near 115 mph (185 kmh). Jova is moving to the north-northeast at 5 mph (7 kmh). The National Hurricane Center expects Jova to speed up a little and turn to the north tonight. That means that the eye of the hurricane will approach the Mexican coast today and make landfall this evening.
Warnings continue to be in effect for Mexico as Jova slowly nears. A Hurricane warning is in effect from Punta San Telmo to Cabo Corrientes. A Tropical Storm Warning is in effect from Lazaro Cardenas to Punta San Telmo and Cabo Corrientes to El Roblito. Residents in the warning areas can expect significant flooding from storm surge and rough seas. Rainfall is forecast between 6 and 12 inches, with isolated totals to 20 inches. Residents should check local forecasts and prepare for this powerful hurricane.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
