Hubble to unravel the mysteries and unsolved mysteries


13/09/2007

Thanks to the amazing photographs taken a revolutionary Hubble Space Telescope in 1990, we had to completely rethink their understanding of the universe. Hubble, with its incredibly clear pictures of deep space, not only shed light on a long-felt mysteries that baffled scientists, but also brought a lot of new mysteries that have yet to be resolved.

Dark matter may repel ...

The universe emerged during the Big Bang. But before starting the universe’s age remained a mystery. More precisely measuring the distances to distant galaxies and the speed of their movement to the extent that, as the universe expands, the telescope allowed to assume the approximate age of the universe: 13.7 billion years old.

But at the same time, and high surface Hubble telescope unexpectedly discovered that the expansion of the universe is the acceleration, instead of being slowed down (as would be logical to suppose, taking into account the gravitational forces galaxies). The repulsive force, which leads to the accelerating expansion caused by dark matter, which filled about 70 percent of the universe. And this dark matter remains today one of the most mysterious puzzles that exist in the scientific world.

... and perhaps draw

Galaxies are not enough normal matter to hold together a giant cluster of galaxies in which they exist. Therefore the world’s leading scientists debate about the existence of gravity of invisible dark matter, which holds galaxies together.

Although it remains a mystery what really it represents the dark matter, Hubble helped determine its quantity in the universe. The telescope has identified how much the gravity of dark matter can distort space-time, distorting the light from distant galaxies. In the end it turned out that the dark matter in the universe is five to six times higher than normal.

In addition, the Hubble, with other telescopes helped develop a three-dimensional map of dark matter. This map shows that dark matter clumps eventually grow in size, indicating that the dark matter inherent to the usual laws of gravity, and not something else. Understanding the behavior of dark matter will help scientists to understand what exactly it is. And while the card will help explain how the universe got a weblike structure, which we see, based on the location of galaxies in space.

Other unraveled and unsolved mysteries.

The biggest explosions in the Universe

First, bursts of gamma radiation (the largest explosions in the universe) satellites discovered in the late 1960s, but scientists could not figure out where the radiation came from. Hubble has helped to establish that it came mostly from hot, young, very massive stars in distant galaxies. Such stars are in the universe a huge amount destroyed with incredible force, producing bursts of gamma radiation.

Photographing other worlds

Neither Hubble nor any other telescope has not yet been able to take a picture of an exoplanet. There was, however, one object of which was considered a planet. Perhaps it will continue to be considered per se, but this subject is too far away from its parent sun is too bright and glowing. So perhaps it is not at all the planet.

Protoplanetary disks

Hubble Space Telescope was the first who was able to take pictures in excellent quality discs, consisting of gas and dust. The pictures were so clear, that allowed to consider in disks holes left by emerging worlds during their rotation around their stars. This information helped to shed light on the formation of the worlds, yet much remains to be understood in order to get a clear picture of the formation of the heavenly bodies.

Followers of the Hubble

Developed and is preparing to launch an orbital infrared observatory that allows pictures much fainter objects. New features present in this observatory, will provide much more information from distant parts of the universe. In such an observatory there is every chance even take a picture of a planet orbiting another sun! Visible light that radiated universe was young, gradually shifted to the infrared spectrum is distorted by the expansion of the universe. This telescope will look at a time when just forming galaxies, and the universe was only a few million years. The study of such galaxies will shed light on the not fully understand the process of the formation of galaxies, such as our own Milky Way.

But Hubble will continue to provide valuable information from space, photographing the universe in the visible and ultraviolet spectra of radiation. Our news is the key informers, modern life. You are always aware of all the events of your country.
