Stratospheric vortex effect on the deep sea

Modeling carried supercomputer showed that the stratospheric vortex affect the depth of the oceans and therefore play a role in shaping the Earth's climate, according to "Kompyulenta" referring to the publication in the journal Nature Geosciences.

Events in the stratosphere at an altitude of 10-50 km are reflected in what is happening in the troposphere below it. It is also known that the behavior of the troposphere affects the circulation of the oceans, which in turn determines the climate. One of the earlier studies hinted that the events in the stratosphere can directly affect the oceans, but the conclusion was based on only one climate model, which also covered a relatively short period of 260 years.

Will people get to the stars?

Scientists, engineers, philosophers, psychologists and leading experts in many other fields gathered in Houston last week at a conference entitled 100 Year Starship conferences, to discuss the possibility of making interstellar travel over the next 100 years.

This initiative will accelerate the development of new technologies related to propulsion, life support systems, design starships, and a host of other technologies necessary to send spacecraft beyond our solar system - wherever does not get even a single man-made object, - and to other stars. Since the stars are coming from us at a distance of several light years, this company, no doubt, will be a difficult and risky.

Scientists are developing a platform for landing on the Moon and Mars

Using the lessons learned from the mission "Apollo" and robotic missions sent to Mars, NASA scientists and engineers study the problems and dangers associated with landing on other planets.

The new technology is called "vertical takeoff - a vertical landing." According to the group, operating within the design and technology of NASA's Kennedy Space Center, Florida, the best approach to planning involves landing on a predetermined spot landing area.

New confirmation of the hypothesis of a comet Clovis

A new study advise the hypothesis of Clovis comet - a giant celestial body collision with the Earth, which occurred nearly 13,000 years ago, which is completely erased from the face of the planet ancient North American Clovis culture.

An international team of scientists from seven institutions of the United States argues that the neglect of three key protocols, including sorting the samples by size, explains why the team, the disputed theory that Clovis comet, did not find the iron-rich and silica-magnetized particles in the places that she explored.

Astronauts’ spelunkers returning from a training mission

An international team of astronauts who took part in a training mission, organized by the European Space Agency, has returned home after spending six days in the caves under the ground. Journey to the surface from their underground camp took the mission about five hours.

CAVES mission astronauts gave the opportunity to feel what it means to work as a cohesive and effective team during long space flights. In particular, they were able to hone their leadership and teamwork skills, working in a multinational team, which is typical for the International Space Station.

1000 years of war in five minutes

YouTube user made a five-minute film, which are all the wars that have taken position around the world in 1000. Chronological order the conflicts around the world since 1000 and until 2008.

War and global conflicts are, unfortunately, the key milestones in our lives, and this is evidenced by Jordi Colomer, user YouTube.

The distance from Earth to the Sun, finally identified

How far the Earth is from the Sun? This apparently simple question is actually a matter of dispute scientists for over a hundred years.

How to solve a specific point on the Earth to measure? How to determine what distance from the Sun to calculate - up of vapor or flames?
