25 000 light years from Earth discovered a huge planet eight times bigger than Jupiter
An international team of astronomers has discovered a world that is 2,500 times the size of Earth.
A planet called MOA-2011-BLG-322 about 8 times that of Jupiter, which is the largest planet in our solar system. Astronomers believe it orbits around a star, distant from us at a distance of 25 000 light-years and with a mass equal to a third of the Sun.
Huge world, exceeding the size of the Earth 2,500 times, was discovered by an international team of astronomers. Artistic representation of an unknown planet
As reported by Ian O’neill in Discovery News, the giant planet was discovered using a technology known as “microlensing”.
Microlensing uses the General theory of relativity of albert Einstein, which assumes that gravity is actually the curvature of space and time. Continue reading
The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.
The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.
However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading
Flight to the Red planet – the most ambitious project of the American space Agency. Meanwhile, he raises a number of issues. Among them – long stay onboard the ship during the flight to Mars that will take at least six months. Note that the diameter of the ship Orion, which NASA astronauts will fly to Mars, comparable to the length of the van.
One of the solutions to the problem of providing astronauts the US more volume on Board. The private rooms, space for physical offices – these and more should ideally be on Board the “Mars” ship. To solve these issues will help manned module connected to the Orion unit. It is assumed that the docking will be performed in space. However, about the appearance and the capabilities of the module it is for certain not known.
But it turned out. what NASA intends to spend on its development 55 million. (some of these funds have already been allocated to developers). In this case a working prototype could be ready in 2018. Then, in 2020-ies, the module will be tested near the moon. And only in 2030-ies something similar will be tested in real conditions during the flight to the Red planet. Note that the flight itself will be (if will be) is not before this time. Continue reading
