How is the carapace.

New research finds that the carapace, which is a complex structure that consists of 50 pieces of bone that have evolved long before the dinosaurs to rule the world.
In the latest edition of the journal Current Biology, The research said it shelled turtle and it is older than the Jurassic Park. The structure of the turtles that are designed to be durable and long-lasting this represents an adjustment for several million years ago.

Tyler Lyson of Yale University and the Smithsonian museums, said armature that began to change when more than 260 million years ago in the Permian era “like other complex structures. Carapace that evolved millions of years ago and gradually developed into the shape that it is today. ”

Carapace shield is the same as one solid piece. But because it was built with pieces of bone formation, it is combined with a way to connect to the ribs and the backbone of it.

“The reason is that most animals are not created through the expansion shell and connected to the ribs is probably because of ribs, reptiles and mammals, it is intended to aid ventilation of the lungs. If we include ribs with protective shell body and what it is we need to find new ways to breathe it. ”

He explains how turtles use the above method to create a turtle shell with the help of a one-line muscle itself. Continue reading

A comet impact and the extinction of the dinosaurs occurred at the same time.

The extinction of the dinosaurs remains a mystery of a human till now. Many people believe that because the volcano, meteorite, comet, climate changes, But no one knows the correct answer. But today BGC University of California, Berkeley and the University of the Netherlands and the United Kingdom. Discover the precise time as you have found one of the world when dinosaurs went extinct 66 million years ago, as well as other adverse events that follow in their pitches. Continue reading

Pioneer and Voyager spacecraft’s purposeful journey in space.


Second project of NASA spacecraft that was released to the world since more than 40 years ago.
 The spacecraft Pioneer 10 had lost contact for nearly 10 years ago (Last Contact time is 2003), which believes that if the vehicle has not been the object of deep space, the spacecraft Pioneer 10 continues to travel outside our solar system and so with such conviction and courage. The Voyager spacecraft signal is extremely faint.  The Pioneer and Voyager is a project of NASA spacecraft designed to travel outside the solar system in a direction opposite to the spacecraft Pioneer 10 is traveling in the opposite direction of motion of the sun in the Milky Way galaxy.

Escape velocity is the speed to take the object to be far away from the influence of the gravity of the fit. If you want to send a spacecraft out of Earth’s gravitational field. The spacecraft is moving faster than the speed of withdrawal. Escape velocity is about 11.2 km / s or 40,320 km / h.

The space probe Voyager Program is a non-person force, created by the jet propulsion laboratory and received funding from NASA. Composed of two space probes Voyager 1 and Voyager 2 were launched in the year 1977 serves to store valuable information about the solar system planets by use the location of the planet at the late 70s. Although at first it was designed to explore the Jupiter and Saturn. Both vehicles, but also its mission in space to the outer Solar System. Today, both vehicles are on the road heading out of the solar system.
 The travel path of the spacecraft, Voyager project was to visit the outer planets. And the speed is high enough to leave the solar system. Continue reading

100-year anniversary of the beginning of polar exploration.

It is confusing for the North Pole and South Pole. With the belief that North Pole to the South Pole, the coldest temperatures are extremely hot temperatures. But the truth is not it. The negative pole is cold and has the same iceberg.
 And to the South Pole is much colder than the North Pole. South Pole is at the south end of the Geographic South Pole. As one of the two axis of rotation perpendicular to the surface. (The other one is Geographic North Pole).
 At latitude 90 degrees south on the mainland of Antarctica. The first man to reach the South Pole is a geographical name, the Norwegian explorer Roald Amundsen on December 14, 1911.

Dating back to 100 years ago, the Norwegian and British explorers compete to reach the “South Pole” is one of the first and the other behind to be near (When it comes to transportation in that era), but other people can not survive the cold has come back from the land. Even then they opened the door to exploring the world with a unique environment. Continue reading

Last flight of ATLANTIS end of space shuttle legend

NASA set to release “ATLANTIS” of 8 July. Ended 30 years of age by only four space shuttle astronauts to perform their duties. A limited number of people for emergency crews to be sent back by the ships of the Russian Soyuz space smaller. NASA set launch of Space Shuttle Atlantis on July 8, 2011 at 11:00 am at rocket base 39A of the Kennedy Space Center in Florida, United States, and the crew jumped to sky forward to International Space Station. This is a final NASA space shuttle. For the crew to travel on the flight last week. The flight commander Chris Ferguson. Doug Hurley and expert on the pilot’s flight Sandra Magnus, and Rex Walheim.
Flight of Atlantis and will be Flight 135 in the space shuttle program of NASA that started 30 years ago with the mission for 12 days on the Space Shuttle to carry spare parts for the space station up. with The lab space, still continue to function even after the end of the space shuttle.
