The mystery of dark energy

Dark energy is believed to account for 68 percent of all energy in the known universe, and is responsible for its constant expansion. The particle, which is associated with dark energy has long been predicted, but no one has yet udalo detect it.

All forms of energy that are known to have a particle physics associated with it. 

NASA shares the latest pictures of Dione

Automatic interplanetary station, NASA Cassini gave the highest quality pictures of one of the largest of Saturn's moons Dione, which were made on August 17 during the closest approach to the celestial body.

The space agency also reported the sad news, these are the latest images of Dione, which is connected with the approaching end of the research mission of closest approach to the satellite during the flight of August 17, 2015 amounted to 475 km.

China is making one of the largest radio telescopes in the world

China next year, intends to complete the construction of the five hundred meter Aperture Spherical Telescope (FAST) - one of the world's largest radio telescopes. As the name implies, the diameter of the telescope is 500 meters. Thus, according to this indicator FAST significantly surpass radio telescope at the Arecibo Observatory, which has a mirror diameter of about 305 meters of the reflector is currently one of the largest in the world (using one of the aperture).

"Space": running on the waves of gravity

A hundred years ago, an inquisitive mind of a genius, Albert Einstein assumed that the universe is filled with gravitational waves, and even described their properties. To this day, scientists continue to look for them. The "Space" invites viewers to witness these searches in Hanover, Germany.

Thus, all objects of the universe - colliding black holes, collapsing stars, planets - create ripples in the fabric of space-time, slightly distorting, deforming it. This "ripple" is the gravitational waves. 

Top 7 striking facts about time

1. Once a year on Earth lasted 486 days, it was about 800 million years ago, before the birth of ancient life in the era of large-scale glaciation of the Earth. Hundreds of millions of years later, in the era of the dinosaurs, the year was reduced to 370 days. He is now, as you know, is 365 days. What is happening? The facts that the Earth rotates more slowly, because it "slows down" lunar gravity.

What are the limits of human vision?

From observations of distant galaxies light years from us to the perception of invisible colors, Adam Hedheyzi on BBC explains why your eyes can do incredible things. Take a look around. What do you see? All these colors, the walls, the windows, everything seems obvious, as it should be here. The idea that we all see it because the particles of light - photons - that bounce off of objects and fall into human vision, it seems incredible.

What happens to a person without a Spacesuit in Space

Imagine you were thrown out of the space station airlock without a spacesuit. You can panic and desperately trying to escape. How much time do you have to find the source of air and atmospheric pressure needed? Spoiler: very little. But more than you think.

Scientists mission OSIRIS-REx hope to find organic asteroid Bennu

In September 2016, NASA plans to launch a spacecraft returned to study the asteroid. This mission will help scientists better understand the composition of asteroids, their origins aspacecraft nd perhaps even the origin of the Earth. The mission OSIRIS-REx (Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer) will allow lifting the veil of secrecy over the history of the formation of the Sun and planets. 

Hubble peered into the history of galaxies

This picture was taken with the Hubble Space Telescope agency NASA and ESA. It shows the dwarf galaxy NGC 1140 is located 60 million light-years from Earth in the constellation Eridanus. As seen in this image, the galaxy NGC 1140 has an irregular shape, like the Large Magellanic Cloud - a small galaxy is a satellite of the Milky Way

A Close Look at the young cosmos

Astronomers for the first time a more detailed look at the development time of normal galaxies succeeded. Observations of an international team of researchers with the radio telescope ALMA plant in the Chilean Atacama Desert show fresh cool gas from which new stars can form, apart from the central region of a young galaxy

Life on Mars may be hiding in Opals

The research team from the University of Glasgow had physical evidence that could help find life on the Red Planet.  Scientists have discovered that the Martian meteorite that fell near the Egyptian village of Nahla in 1911, contains traces of opal - precious stones, often used in jewelry. Material for the study provided the Museum of Natural History in London.

Scientists have mapped the Pluto in format Google Earth

Community service Google Earth can now explore the dwarf planet Pluto on a map drawn on the basis of images from the spacecraft, "New Horizons" by NASA. The interactive map gives a preliminary idea of what it looks like, this distant planet.

If water leaves from the Planet- will like the Earth to Mars

The two closest to the Earth planet - Mars and Venus - once had vast oceans, extending over many millions of square kilometers. But all the planets with liquid water on the surface is very fragile. Venus could not keep their oceans, and they vanished into space. Recently we learned that Mars lost most of their water, then it turned into a dry and cold desert.

What happens if you fly through the Earth?

The Funniest part of theoretical physics is that you can ask a stupid question and get your answer (sometimes too stupid). For example, what if you drilled a hole through the center of the Earth and leap through it? "Who could do such a stupid thing to do?" - You ask. Apparently no one. Such an act will kill you very sophisticated and split the millions of times. Let's assume that some brave soul ventured into it for the sake of science? What can happen, theoretically?

10 Mysteries of the solar system, which are confusing our best scientists

Even if we have already told you about the mysteries of our solar system, here , here and here , they are innumerable, and we are back, taking in his arms even more mysterious sights and features that confuse our scientists. Sometimes they even incite conspiracy theories, and it adds even more fuel to the fire.

Mysterious "sounds" in space
The video above presents five mysterious "sounds" of the cosmos, three of which, of course, occurred in our solar system.

NASA probe discovers the 'heart' of Pluto

New Horizons spacecraft gets closer and closer to Pluto and as it does capture historical images. One of the last photographs revealed a nearly perfect heart on the surface of the dwarf planet. It will also catch a few bright spots that can be icecaps.

Destination Pluto: A land ship approaches the confines of the Solar System

Discovered in 1930, we now know that Pluto is the brightest numerous swarm of small bodies that, as a second asteroid belt orbiting the sun beyond the planets. Are so far we know very little about them.
We know they are mostly ice, which are more like comets, asteroids and many short-period comets come from there. You will craters? Will rings? Will rivers of neon, nitrogen geysers? Will one meteorology, polar caps, cryovolcanoes, underground seas?
