Fires have burned some 14 000 hectares on the western part of Tenerife since Monday, while some 10 000 hectares of woodland in the southwest of Gran Canaria have been charred since Friday, Paulino Rivero, head of the regional government, said.
Winds of 65 kilometers per hour and temperatures of more than 40 degrees Celsius have hampered efforts to smother the blazes, authorities told the Associated Press.
There are seven islands in the Canary Island archipelago, located some 95 kilometers from the northwest coast of Africa in the Atlantic Ocean. Tenerife is the biggest island in the region, while Gran Canaria is the most populated.
These images were acquired by Envisat’s Medium Resolution Imaging Spectrometer (MERIS) optical instrument working in Full Resolution mode to provide a spatial resolution of 300 metres and are available on ESA’s MIRAVI website, which gives access to Envisat’s most recently acquired images.
MIRAVI, short for MERIS Images RApid VIsualisation, tracks Envisat – the world’s largest Earth Observation satellite – around the globe, generates images from the raw data collected by MERIS and provides them online within two hours. MIRAVI is free and requires no registration.
Envisat circles the Earth in a polar orbit at an 800-km altitude, allowing MERIS to acquire global coverage every three days.

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...
