SUPERTROPICAL FULL MOON

The Full Moon on June 1, 2007 was particularly brilliant, than the full moon was appeared very bright. The same thing happened the night of Saturday 30 of that month.The reason is that the full moon of that month flew over the southern regions that can be achieved, illuminating landscapes where seldom visited by this star. On 1 and 30 reached the Moon Lunar Tropic of Sagittarius, the southernmost latitude that can be achieved, equivalent to the Sun Tropic of Capricorn, at latitude 23.44 degrees south.

For Supertropical we mean that the full moon occurs when flies latitudes south of the Tropic of Capricorn.

Full moons occur when the phase near full moon coincides with the lunar perigee, when the Moon is closest to the 19 March 2011 was 356,577 miles away. The last time the moon was this close was in 1993 when 356,529 km perigee occurred 18 years ago.No wait that long for the next giant full moon, this will occur on November 14, 2016 at 11:24 UT the Moon is just 356,511 miles away.

Due to media attention the press gave the event, "this must be the most photographed Full Moon history. The size and brightness with which we see the full moon in the sky, at first, depends on: How far is the perigee. 

ON THE MOON THE GRAIL SHIPS ARRIVED

It is the mission GRAIL (Gravity Recovery and Interior Laboratory), which aquaculture the crust and the core mole to discern its structure."Our team is not going to have a traditional New Year celebration, but I hope to see our two ships safely in lunar orbit, something that gives us all the excitement and the feeling of euphoria that any necesiatría in a work of this kind "said David Lehman, GRAIL project manager at the Jet Propulsion Laboratory (JPL) in Pasadena, California.

The distance from Earth to the Moon is about 402,336 km. At NASA's Apollo missions took them about three days to travel to the moon. Launched from Cape Canaveral on 10 September, the ships GRAIL (Grail in Castilian) have traveled more than 4 million miles to get there.

Tyco crater on the Moon

The Moon is still a goal for NASA; on June 10 last the satellite NASA Lunar Reconnaissance Orbiter was able to take this dramatic image thanks to its steep orbital angle of 65 °. The image is the central peak of the crater Tyco in the southern hemisphere of the Moon.Tyco is a place known to fans as it is one of the most outstanding places on the Moon. It is located at latitude 43.37 ° S, 348.68 ° E, and has about 82 kilometers in diameter.

The height of its central peak in the image above rises 2 km above the crater floor and the distance between the bases and is 4.7 km Comber.

The complex central peak of Tyco crater is about 15 km long and is easily visible with a backyard telescope. 

An object hit the earth

The object had ten kilometers in diameter and scientists have not yet determined exactly whether it was a meteorite or comet, but agree that their average speed was 25 to 30 kilometers per second and left a footprint impact (crater) of approximately 200 kilometers in diameter. 

After impact the earth was plunged into total chaos. Caused large fires occurred due to a temperature of up to 20 thousand degrees Celsius were recorded throughout the Americas, there were earthquakes whose intensities ranged from 14 to 16 degrees Richter and other disturbances that resulted in numerous seismic and volcanic eruptions. In addition, heavy rains were present acidic and formed huge waves, which now are known as tsunami (Japanese word derived from), traveling horizontally at speeds of up to 750 mph and reach between 15 30 meters in height. In the case of the Chicxulub impact has been estimated that the tsunami could have reached heights of 100 to 200 meters, says the geologist José Manuel Gradates Nishimura, investigator assigned to the Program of naturally fractured reservoirs, the Mexican Petroleum Institute (IMP).

The Largest impact craters that have beaten the Earth

Imagine staring at the sky, which gradually gets closer, more and more closely. That point doubling in size every second, to darken the sky. His entry into the atmosphere is accompanied by light and heat, the giant rock wrapped in a meteor full of death that goes directly to you. 

It sounds like the introduction of a catastrophic film, however not very far from reality as these impacts ended the lives of potential witnesses to the event in his time, leaving only the record of their impact on Earth's surface. Today we will show the largest impact craters that have impacted the Earth. In ascending order according to their size, see:

The Earth hitting after 35% meteorites enter atmosphere does not break

A small impact crater discovered in the Egyptian desert could change the calculations of risk of impact on our planet, according to a recent study. The Kamil crater, one of the best preserved of those found on the Earth, was discovered in February during a survey of satellite images with Google Earth. It is believed that the crater was formed in the last two thousand years. 

The Italian and Egyptian crater found recently visited and studied the hole 45 meters wide by 16 deep. They also collected thousands of pieces of space rocks scattered in the surrounding desert. Based on the calculations, the team believes that a solid iron meteorite, almost intact, between 5,000 and 10,000 kilos crashed into the desert at speeds in excess of 3.5 kilometers per second.
