For many years scientists know about strong wind on Venus. However thanks to the spacecraft “Venus-Express”, it became known that increased intensity and force of the winds on Venus. They turned into the real hurricanes which many times over surpass force of terrestrial hurricanes. At this stage scientists who are engaged in studying of winds on atmosphere of Venus, can’t explain the mechanism of action and emergence of similar winds. Very difficult, but it is important to understand that provokes so strong wind on Venus. Their speed sometimes reaches 300 km/h. And in recent years even 400 km/h. By the words of Russian scientist Igor Khatuntsev, earlier they never observed similar speeds of hurricanes on Venus.
Mercury Mercury and Venus are the innermost of the eight planets in the Solar System. It is also the smallest, and its orbit has the highest eccentricity of the eight. It orbits the Sun once in about 88 Earth days,…
The transit of Venus across the sun is one of the rarest celestial sights visible from Earth, one that wowed scientists and amateur observers around the world Tuesday (June 5). The event, arguably the most anticipated skywatching display of the year, marked the last time Venus will cross the sun (as seen from Earth) for 105 years. Venus transits occur when Venus reaches a point in its orbit that brings the planet directly between the Earth and the sun.
Venus will pass in front of the sun from Earth’s perspective on Tuesday (June 5; Wednesday, June 6, in much of the Eastern Hemisphere), marking the last such Venus transit until 2117. However, there’s a chance to observe an Earth transit less than two years from now using a little creative thinking, some researchers note. In January 2014, Jupiter will witness a transit of Earth. And we can see it too, the astronomers say, by training NASA’s Hubble Space Telescope on the huge planet and studying the sunlight it reflects.
On June 5th, 2012, Venus will pass across the face of the sun, producing a silhouette that no one alive today will likely see again. Transits of Venus are very rare, coming in pairs separated by more than a hundred years. This June’s transit, the bookend of a 2004-2012 pair, won’t be repeated until the year 2117. Fortunately, the event is widely visible. Observers on seven continents, even a sliver of Antarctica, will be in position to see it.
Astronomers are planning to use NASA’s Hubble Space Telescope to observe next month’s historic transit of Venus across the sun’s face. But there’s a twist. Astronomers can’t point Hubble anywhere near the sun, because our star’s bright light could damage the telescope’s super-sensitive instruments. So Hubble will watch the June 5-6 Venus transit by using the moon as a mirror. The goal is to see if Hubble can determine the makeup of Venus’ atmosphere by studying sunlight that has poured through it.
Magnetic phenomenon that causes auroras on Earth has now surprisingly been discovered creating giant magnetic bubbles around Venus, a planet without a magnetic field. The Northern and Southern Lights on Earth are caused by magnetic lines of force breaking and connecting with each other. This process, known as magnetic reconnection, can explosively convert magnetic energy to heat and kinetic energy.
A year from now, it is possible that “comet fever” will be running high when a newfound comet emerges into view in the evening sky. But while some scientists have high hopes for a spectacular 2013 sky show by the comet, it is still far from certain. When astronomers at the University of Hawaii at Manoa announced last June that they had discovered the new comet, it was a distant and inconspicuous object.
On June 5-6 of this year, a rare celestial event, called a transit of Venus, will take place.Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. During the transit, Venus will pass directly in front of the sun from Earth’s perspective, appearing as a small, slowly moving black dot.
