SpaceX Dragon capsule Returns to Earth

The American SpaceX company’s Dragon cargo capsule is heading back to Earth having spent a week attached to the International Space Station (ISS). Built by commercial company Space Exploration Technologies Corp. (SpaceX), the Dragon capsule was detached from the space station by astronauts using the outpost’s robotic arm, which officially released the spacecraft at 5:49 a.m. EDT (0949 GMT). Dragon is the first private spacecraft ever to visit the $100 billion space station.

Transit of Venus 2012

Transit of Venus 2012

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.

Annular Solar Eclipse 2012

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.

Pacific Reef Shark Populations in Steep Decline

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.

Unmanned Cargo Ship Arrived at Space Station

Unmanned cargo ship arrived at the International Space Station on March 28. After five days chasing down the space station in orbit, the European Space Agency’s third Automated Transfer Vehicle (ATV-3) arrived at the complex at 6:31 p.m. EDT (2231 GMT). The vehicle is carrying about 7 tons of food, water, clothing, experiments and fuel for the space station in what is the heaviest load ever delivered to the outpost by a robotic spacecraft.

Amasia the Next Supercontinent in North Pole

According to scientists at Yale University America and Eurasia will crash into each other over the North Pole in 50-200 million years time. A supercontinent last formed 300 million years ago, when all the land masses grouped together on the equator as Pangaea, centred about where West Africa is now. After looking at the geology of mountain ranges around the world, geologists had assumed that the next supercontinent would form either in the same place as Pangaea, closing the Atlantic Ocean like an accordion, or on the other side of the world, in the middle of the current Pacific Ocean.
