Astronomers from Spain submitted the description of a huge storm on Saturn (known as the Big White Spot) 2010. To find out the phenomenon reasons, scientists analyzed the data obtained by the spacecraft Cassini. Researchers established that the speed of streams in an upper atmosphere of Saturn reached 570 kilometers per hour or about 160 meters per second. For comparison, the strongest hurricanes on Earth differs the speed of a wind in 140 meters per second and thus completely destroyed the majority got to a zone of disaster of constructions. The storm on Saturn led to emergence of the spot seen even in not the most perfect telescopes from Earth.
The Polish scientists suggested to use a radar operating in the range from 3 to 3000 hertz. One such radar is already established in mountains in the south of Poland. He allows to define not only a place, where there is a thunder-storm, but also its intensity. This innovative global system of tracking the storm and thunder-storms worldwide will be able to work in real time. By the words of the scientists the system of global monitoring of the storm activity allows in real time to trace the storm events, including in territories, which are not captured by existing systems of tracking. According to the scientists, this project costs approximately 2 million dollars. Existing radar uses, generally radio frequencies in the range from 3 to 300 kilohertzes, and an auxiliary radar — from 30 to 300 megahertz. Radius of action of this radar is limited by 5 thousand and 50 kilometers respectively. When using existing technologies the network of stations has to be extensive, and it is not always possible, therefore, the accuracy of modern systems of tracking the storms is not high
According to a recent study, tens of billions of planets around red dwarfs are likely capable of containing liquid water, dramatically increasing the potential to find signs of life somewhere other than Earth. Red dwarfs are stars that are fainter, cooler and less massive than the sun. These stars, which typically also live longer than Class G stars like the sun, are thought to make up about 80 percent of the stars in the Milky Way, astronomers have said.
The sun erupted in an amazing solar flare on April 16, unleashing an intense eruption of super-heated plasma that arced high above the star’s surface before blasting out into space. The powerful solar flare occurred at 1:45 p.m. EDT (1745 GMT) and registered as a moderate M1.7-class on the scale of sun storms, placing it firmly in the middle of the scale used by scientists to measure flare strength. The storm is not the strongest this year from the sun, but photos and video of the solar flare captured by NASA spacecraft revealed it to be an eye-popping display of magnetic plasma.
NASA’s Solar Dynamics Observatory spacecraft has captured video of a massive solar tornado five times wider than the Earth twisting its way across the surface of the sun. As said researchers NASA’s Solar Dynamics Observatory (SDO) looked on as the huge, swirling storm raged on Sept. 25, 2011, spinning solar gas at speeds up to 186,000 mph (300,000 kph. Here on Earth, tornado wind speeds top out at around 300 mph (483 kph).
New video of Jupiter are the first to catch an invisible wave shaking up Jupiter’s jet streams, an interaction that also takes place in Earth’s atmosphere and influences the weather. The video, made from images taken by NASA’s Cassini spacecraft when it flew by Jupiter in 2000, are part of an in-depth study conducted by a team of scientists and amateur astronomers led by Amy Simon-Miller at NASA’s Goddard Space Flight Center in Greenbelt, Md..
With the help of data from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) NASA models have now provided more information about the two CMEs associated with the two March 6 flares. The first is traveling faster than 1300 miles per second, the second more than 1100 miles per second. NASA’s models predict that the CMEs will impact both Earth and Mars, as well as pass by several NASA spacecraft, Messenger, Spitzer, and STEREO-B. The models also predict that the leading edge of the first CME will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours).
NASA’s TRMM satellite detected and imaged the heavy rainfall before the storm Washi came ashore.Heavy rains caused by Washi have attacked the Philippines bringing torrential rains and mudslides to the country
New images from NASA’s Cassini spacecraft chronicle the birth and evolution of the colossal storm that ravaged the northern face of Saturn for nearly a year.
