Solar Flares

Solar flares reached to the Earth

The loaded particles, which have been thrown out by the Sun during four powerful solar flares in previous days, reached to the Earth. The American GOES satellites fix growth of concentration of protons in near-earth space. The weak proton solar flare testify the forecast of the center of space weather of National administration of oceanic and atmospheric researches of the USA (NOAA) These are the remains of streams, which were injected by earlier active area 1748 at east edge of the Sun. The main streams passed by. The astronomers don’t expect any dangerous phenomena. Since Monday on the Sun there were four powerful x-ray flashes of the highest class X, which weren’t observed since October, 2012. Each such solar flare was accompanied by emissions of solar plasma and the loaded particles of high energy. Their source is group of 1748 spots, which was at east edge of the Sun therefore emissions took place and passes by the Earth, and won’t cause magnetic storms.

Water cristals

The Moon and the Earth have the same source of water

Scientists consider that asteroids were a source of water on the Moon and in Earth . Astronomers analyzed isotope structure of samples of a deep cloak of the Moon, delivered by mission “Appolo” to the Earth, and came to a conclusion that water molecules in them and in a matter of Earth come from the same source, which most likely were asteroids. It is considered, that the Moon was formed as a result of collision of a protoplanetary body, with Earth “germ”. Collision led to emission of a matter of hot cloud of debris and proto-Earth in space, from which was created the Moon. This cataclysm was considered as the reason of why its subsoil and a surface are almost deprived of water. This hypothesis was called into question in February 2012, when scientists found unexpectedly high concentration of water in lunar magmatic breeds. Astronomers under the leadership of Erik Hauri from Carnegie’s Institute in Washington (USA) found one more argument against the classical theory of formation of the Moon, having analyzed isotope structure of breeds of its cloak.

Earth core

The Earth core was one thousand degrees hotter

The core of Earth was warmed up to the temperature of 6 thousand degrees Celsius, it is one thousand degrees more than the previous estimates; it allows to explain existence of a magnetic field at our planet that was difficult earlier. The lithosphere of Earth consists of three layers — crust, a cloak and a core. Studying of a core and cloak layers directly is impossible in practice because of deep water on which their breeds lie. Therefore scientists investigate properties of a subsoil of Earth, watching laboratory experiments with an ultrahigh pressure and temperature. The scientists from the Commissariat of nuclear power of France in Grenoble could calculate temperature of firm part of a core of Earth, having tracked how iron behaves with an ultrahigh pressure. For this purpose scientists developed an original technique, which allows illuminating an alloy in the camera of a high pressure with help of x-ray radiation. As scientists explain, their technique allows learning an aggregate state of an alloy, whether there was it liquid or remains a firm body. Similar data are necessary for studying of behavior of a matter of a core as temperature of melting and other properties of iron cardinally change with an ultrahigh pressure. The scientists used the technique for measurement of properties of a slice of iron, which was squeezed on 2,2 million atmospheres in a diamond anvil and is heated to 4,5 thousand degrees Celsius by means of a laser beam. Scientists used these data for temperature calculation in firm part of a core pressure in which reaches 3,3 million atmospheres. To their surprise, temperature in it reached 6-6,5 thousand degrees, that is one thousand more than the previous estimates.

Earth day special google doodle

Google celebrated the Earth day with a special doodle

Traditionally this day the actions are directed on ecological education and environment protection held. The Google logo is replaced on Monday with the interactive image of wildlife in development — mountains, the lake with small fishes, trees, animals, flowers. By pressing Play button on the virtual sun, it will begin the daily cycle. After end of one cycle the season — winter, spring, summer or fall changes. The user also can operate elements of doodle — to blow off dandelions, to cause a virtual rain or animals from a hole. The tradition to celebrate the Earth Day created in the USA at the initiative of the ecological activist of the Gay lord of Nelson, and for the first time the Earth Day was celebrated on April 22, 1970. 20 years later this day became the international action in which 200 million people from 141 countries of the world participated. In 2009 the General Assembly of the UN at the initiative of Bolivia proclaimed on April 22 in the International afternoon of Mother Earth.

Earth

Life existed long before appearance of the Earth

According to the last statements of scientists, there is a high probability, that life existed long before emergence of the Earth, and, it is quite possible, and even outside our Solar system. Moore’s law says that the numbers of transistors, which take place on a crystal of the integrated scheme, will double each 24 months or two years. According to David Hausa’s forecasts from Intel, doubling of productivity of processors happens each 18 months, and the combination of growth of number of transistors and speed of each separate transistor becomes the reason for that. So, if to apply Moore’s law, and to use it for counting in the opposite direction, we’ll come to conclusion, that we come by 1965 when the first microchip was invented. Now two scientists-geneticists applied Moore’s law to the speed, with which life on Earth develops, developing into more and more difficult forms. As a result results which show were received, that organic life appeared even long before appearance of the Earth. Alexei Sharov from National institute of aging in Baltimore a little differently applied Moore’s law. It replaced transistors with nucleotides (DNA and RNA construction blocks) and made calculations.

December 21 of 2012 NASA Says About End of The World

Representatives of the U.S. space agency said about the end of the world on December 21 of 2012. Experts from NASA dispelled rumors that the end of 2012 can be a cosmic cataclysm . Many publications have predicted end of the world December 21 of 2012. Scientists explain that the rumors were caused misinterpretation of the Mayan calendar. And despite the fact that many professionals often wrote about this cataclysm , the Internet, newspapers and magazines are not willing to back away from such “enticing” a topic that has attracted the attention of many readers.”If the end of the world will be one day, we hardly know about it in advance. Rather, it happens unexpectedly and quickly” – said the NASA experts, – “although, of course, it all depends on whether it will be a disaster and how it will be triggered. If culprit is a huge asteroid, perhaps we will know about it “. If Nibiru or some other planet X would fly toward the Earth, astronomers have long noticed, but they do not, so it makes no sense to think about the next disaster. Live and enjoy life on the eve of the New Year” – added to NASA researchers.

Mexico Volcano Erupts

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.

Ontario Lacus Very Similar to Etosha Salt Pan

A recent study finds that the lake known as Ontario Lacus on Saturn’s moon Titan (left) bears striking similarity to a salt pan on Earth known as the Etosha Pan (right). A group led by Thomas Cornet of the Université de Nantes, France, a Cassini associate, found evidence for long-standing channels etched into the lake bed within the southern boundary of the depression. This suggests that Ontario Lacus, previously thought to be completely filled with liquid hydrocarbons, could actually be a depression that drains and refills from below, exposing liquid areas ringed by materials like saturated sand or mudflats.

First Man in Space

For more than five decades, humans have been suiting up and riding rockets to escape the bonds of Earth, but the anniversary of that historic first flight, which blasted off 51 years ago this week, takes center stage on April 12. On 12 April 1961, Russian cosmonaut Yuri Gagarin became the first human to travel into space when he launched into orbit on the Vostok 3KA-3 spacecraft (Vostok 1). To mark the groundbreaking flight of Soviet cosmonaut Yuri Gagarin in 1961, space geeks worldwide will revel at themed parties, and a filmmaker will tweet the mission’s audio transcript live to coincide with the actual time of the flight.
