Scientists found new proofs of that the huge ocean on Mars covered the most part of a surface of a planet billions years ago. The last answers were found in the photos made by Mars Reconnaissance Orbiter from an orbit. Images show that the delta of the ancient river flew into the huge ocean which flooded to one third of the Red planet. By the words of Mike Lamb (the associate professor of geology at the Californian institute of technology in Pasadena) the scientists assumed long ago that northern lowlands of Mars represent the dried ocean on Mars. New research doesn’t give long-awaited absolute proofs, but confirm a hypothesis even more. The team studied pictures with high resolution of part of the northern lowlands, taken by the HiRISE chamber onboard Mars Reconnaissance Orbiter of NASA. HiRISE is capable to allocate details up 25 centimeters for surfaces of the Red planet. In particular, scientists looked narrowly at area in 39 square miles (100 square kilometers) which is part of larger area called by Aeolis Dorsa, being approximately in 620 miles (1000 km) from a crater Gale. Aeolis Dorsa has a set of the crests called by channels which are formed in river day when large objects are transferred by a current and lay down on a bottom. Channels remain on a look after the rivers which created them, dry up, helping researchers to track the past of ocean on Mars.
The team of expeditors led by Bezos found rusted pieces of two Apollo-era rocket engines from the depths of Atlantic ocean. As you know, the Apollo rocket helped the astronauts to fly to the Moon. The expeditors’ team raised the engine parts approximately three weeks, then carried the parts to the launch pad for the lunar missions in Florida. The Bezos team used the sonar equipment for finding the location of sunken engines, which are approximately 3 miles deep in the Atlantic ocean and 360 miles from Cape Canaveral. But there is some unclear fact. The serial numbers on the corroded pieces are missing or it is hard for expeditors to read the numbers. So, the Bezos team can’t know to which Apollo mission the engines belonged.
The scientists of University of Southampton in England, found the first skeleton of an Antarctic Minke whale. This discovering will help the scientists to learn at least nine new species from inhospitable climates in the Earth. The whale is the largest mammal on the planet, but the dead whale in the ocean is exceptionally rare. The skeleton of dead whale found in the Antarctic. The scientists found the 35 foot long skeleton of dead Antarctic Minke whale by the “undersea vehicle”. They searched a crater near the South Sandwich Islands approximately one mile below the surface of the ocean. When dies the whale, the body plunges to the floor of ocean.
The scientists, who were observing the Jupter and its moons, discovered a salt water on the surface of Jupiter’s moon Europa. They suggests, that if someone can get to the moon through the all difficulties, and drink the water, the taste of water will be familiar. The Europa moon of Jupiter, overed with cracks and salt chemicals. The moon also has a gigantic ocean with frozen exterior. Because of this, the moon of Jupiter, is one of the most likely places to find life in our solar system outside of the Earth. In Hawaii the scientists used the telescope Keck, and mapped in the surface of Europa, an infrared wavelengths with 40 times greater resolutions, which they hadn’t obtained in the previous.
Apophis previously known as 2004 MN4, a member of the Aten group of near-Earth asteroids which had been estimated by NASA as having a 1 in 5500 chance of striking the Earth in 2029. Concealing the energy of 65,000 atomic bombs asteroid Apophis with a mass of 50 million tonnes and a diameter of 320 meters will cross the orbit of the moon and rush to the Earth with a speed of 45 thousand miles per hour. In a collision of Apophis might do unseen troubles.
A so-called annular solar eclipse, which took place on May 20, was seen across the globe from late afternoon to early evening, beginning in East Asia and traveling across to the western United States. In an annular solar eclipse, the moon does not completely block the sun, but leaves a fiery ring around its circumference. Observers along a narrow path were well placed to see the full annular solar eclipse, but skywatchers elsewhere (with the exception of the U.S. East Coast) caught a stunning partial eclipse.
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.
According to scientists reef sharks have dropped sharply near populated islands in the Pacific Ocean. The survey by the University of Hawaii showed that the numbers were drastically lower near populated islands in Hawaii, the Mariana Archipelago and American Samoa, compared to more pristine, remote areas in the ocean. As said lead author Marc Nadon from the Joint Institute for Marine and Atmospheric Research at the University of Hawaii they estimate that reef shark numbers have dropped substantially around populated islands, generally by more than 90 percent compared to those at the most untouched reefs.
NASA’s Cassini spacecraft spots new images of Saturn’s moons Enceladus, Janus and Dione on March 27 and 28, 2012. The new photos reveal the plume of water ice and vapor that springs from the south pole of Enceladus, which is Saturn’s sixth largest moon,as well as the pockmarked surface of Dione and the tiny oblong shape of Janus. Cassini made a close flyby of Enceladus on March 27, swooping within about 46 miles (74 kilometers) of the moon’s surface.
