The Curiosity rover, which is designed to explore Mars, has found an ancient oasis on Mars. Researchers working with the Curiosity rover have found salt-enriched…
Iо was opened by Galilei in 1610 together with three other satellites of Jupiter – Europe, Ganymede and Callisto. This planet is “champion” for volcanic activity in Solar System.
Volcanoes on the most geologically active planet of Solar system Io, the satellite of Jupiter, are in the wrong place. They are not coinciding with the center of tectonic activity, which calls into question the computer models.
Ultrahigh tectonic activity of Io is explained so: its subsoil are warmed under the influence of the tidal forces resulting gravitational interaction of Io, Jupiter and her two neighbors – Europe and Ganymede.
The group of astrogeologists by leadership of Christopher Hemilton from University of Maryland in the city College Park (USA) compared the modern models of tectonic activity of Io with a global map of a volcanism on the satellite of Jupiter.
The top of the Kizimen volcano is covered by ashes, lava and various volcanic emissions. The satellite of NASA Earth Observing-1 (EO-1) allowed to register eruption consequences, having made this picture on March 12. It is possible to notice that the smoke column still rises from top while snow covers a lava stream on East side of a volcano. Kizimen is a start volcano, which height makes 2376 m. The form of volcano reminds the Japanese mountain of Fuji before its eruption in 1980. The main crater of a volcano is expressed poorly. Kizimen’s slopes are covered with different volcanic outbursts.View More NASA satellite observes the Kizimen volcano
Some time ago there was an eruption of a Japanese Sakurajima volcano, which threw out melted lava with huge force. This process was accompanied with volcanic lightning. It looks unusually: clouds of a black smoke and lightning escaping from them. The photographer of Martin Rietze could capture this volcanic lightning eruption. There is no consensus among the scientists regarding the formation of volcanic lightning during the eruption. The question connected with the formation of usual lightning, is still in a stage of studying. But the reasons of emergence of volcanic lightning is even less clear. According to the hypotheses, thrown-out bubbles of magma or a volcanic ash carries an electric charge. But volcanic lightning can be formed by collisions as a result directing a charge in a volcanic dust. The scientists found two versions of volcanic lightning.View More Lightning Volcanic Eruption
The newly discovered glass dune fields, spread across almost a third of the planet Mars, likely formed from interactions between magma and ice, or water, interactions that could create the perfect environments for microbial life. The northern lowlands spread across millions of square miles in the Red Planet’s northern hemisphere. But dark sediments in the region have puzzled planetary scientists. Briony Horgan and James Bell, both of Arizona State University, used the European Space Agency’s Mars Express orbiter to re-examine light radiated from the Martian plains.View More Red Planet Volcanic Glass May Be Hotspot for Life
As said researchers Giant coils of lava on Mars suggest a mysterious network of valleys on the planet was born from volcanoes. The origin of the Athabasca Valles region near the equator of Mars has been debated for more than a decade. Some researchers have proposed that lava once shaped the valleys, while others have thought ice was responsible. The way the ground there is patterned with multisided polygons suggests that either fire or ice could be the culprit, such patterns of cracks might have formed due to seasonal fluctuations in temperature if the surface there was rich in ice, but also might have arose as lava cooled and fractured.View More Volcanic Secrets of Red Planet
The world’s most dangerous volcano has erupted 70km (40 miles) from Mexico City, sending plumes of ash and water vapour into the sky. A heavy plume of ash covered the sky over Mexico’s Popocatepetl volcano early Friday morning as glowing rock shot out from its crater. Webcam images on the site of the National Disaster Prevention Center showed the plume rising from the top of the 17,886-foot (5,450-meter) peak at dawn, though clouds obscured the volcano for people further away.View More Mexico Volcano Erupts
An amateur astronomer Wayne Jaeschke has managed to capture recent images of Mars which appear to show cloud like formations on Mars. The image was taken on March 22, 2012. Wayne Jaeschke, from West Chester, Pennsylvania, first noticed the formations which can be seen rising up from the edge of the Martian disk after he took the pictures on March 20. Some observers have suggested the so-called clouds are at least 150 miles away from the surface while others have suggested it could be debris which was disturbed after the Red Planet was hit by a meteor.View More Mystery of Strange Cloud Formations on Mars
The volcanic caldera on the picturesque tourist island of Santorini is showing signs of unrest. But researchers detecting the caldera’s movement say it doesn’t necessarily mean an eruption is imminent. As says Georgia Tech associate professor Andrew Newman, who set up more than 20 GPS stations on the island in 2006, after decades of little activity, a series of earthquakes and deformation began within the Santorini caldera in January of 2011. Since then, the instruments on the northern part of the island have moved laterally between five and nine centimeters.View More Greek Island Shows Signs of Volcanic Activity
About 300 million years ago, volcanic ash buried a tropical forest located in what is now Inner Mongolia, much like it did the ancient Roman city of Pompeii. This preserved forest has given researchers the unusual opportunity to examine an ecosystem essentially frozen in place by a natural disaster, giving them a detailed look at ancient plant communities and a glimpse at the ancient climate. This ancient, tropical forest created peat, or moist, acidic, decaying plant matter. Over geologic time, the peat deposits were subjected to high pressure and became coal, which is found in the area. The volcano appears to have left a layer of ash that was originally 39 inches (100 centimeters) thick.View More 300 Million Years Old Chinese Pompeii Found Buried Under Volcanic Ash
