Our Sun is not the best type of star on our Milky Way Galaxy. This award is a red dwarf, stars that are smaller and cooler than ours. In fact, red dwarfs probably have the largest part of the population of our planetary galaxies, the NASA Hubble Site's reports, that is, tens of millions of people around the world. According to surveys conducted by NASA's Kepler Space Telescope and other observatories, giant planets are about the usual small densities. Some of these rocky worlds live in the vicinity of nearby surrounding areas. When the oceans in the warm climate of these worlds exist, they can feed their lives.
That's good news. The bad news means that many of these rocky planets do not have water and organic matter, as we know the necessary components for living. Planeta was created as a "dry" land that extended more than a million years ago by freezing comets and asteroid material from outer space asteroid asteroids.
Red dwarfs, smaller and darker than our Sun, are the longest stars in the galaxy. However, the planet's backbones with red dwarfs may be dry and lively, according to the new study. Water and organic compounds, as essential to living, make the planet reach the surface of young people.
"The Earth, we know, was formed on a" dry "surface, extruded by hot surfaces, cold and atmospheric water and hundreds of millions of earth, rich in ice materials from the sun's external system and asteroids from asteroids." said researcher at the Stewart Observatory Glenn Schneider in Tucson, Arizona.
This hypothesis is based on a surprising observation of the amazing Hubble telescope in Chile (VLT) and a rapid wind and gas drive around the child and gas near the European Telescope of the High Observation Telescope (VLT). Plans are created on these disks.

Those that are moving in blue are seeming to expose the microscope particles. If this record continues to last, it will be around 1.5 million years. In a short space of time, comet and asteroid material can be washed through the disk. Kometes and asteroids play an important role, such as wet earthquakes such as earthquakes with water and organic compounds, the building blocks of chemical life. If the system of the same system of transport is needed, if the need for planetary AU Mic systems are needed, they would be "dry" and dusty, as it is ideal for living.
The observation is directed by John Wisniewski at Norman University of Oklahoma, whose team is made up of 14 United States astronomers and Europe.
AU Mic's activity is the birthing process of the red dwarf planet, which can reduce the solutions of the world-wide waves through the galaxy. The previous observations suggest that the ultraviolet light of these red dwarf stars distances the atmosphere in the planet that is orbiting. This particular star is only 23 million years old.

Surveys show some of the planet's typical dwarf dwarfs. In fact, they should have a majority of the planetary population of galaxies, tens of millions of miles. Red on the surrounding area has found a living area around dwarfs, but their physical characteristics are very unknown.
Blobs by Blown:
The Hubble spectral spectrum of telescopes (STIS) and VLT observations show that the microscreen drive of the AU Mic magnifies the rapid movements of slanted materials, which imply small particles, may be water and other volatiles outside the system. The researchers do not know how blobs were created. The theory is that these ejections of powerful mixes of stars are eliminated. This energy activity is common in young red dwarfs.
"These observations suggest that the average water medium is rare on red dwarf, because all the smaller bodies that transport water and organic matter dissolve," said Eureka Scientific, a researcher at Carol Grady Oakland, California. Hubble observations
Conventional theory has been a comparatively dry planet for millions of years. Gravitationally disturbed asteroids and kites, cooler solar systems in cold outdoor waters, were bombarded with Earth and ice and the surface of organic compounds. "However, this process could not work on all planetary systems," Grady said.
The group determined the duration of the disk by using an estimated mass of the disk, by means of an independent study, as well as calculating the mass spectrum mass data of the STIS visible data. The mass of each blob is four to ten millions of Earth's mass. Disk mass – A massive 1.7-fold mass on the ground – Based on the data captured by Atacama Large Millimeter / submillimeter Array (ALMA).

Although the masses of the Blobs road seem small, each blob can extend the diameter to a minimum from Sun to Jupiter. Today, teams have seen six lines of output, but it is possible to have a continuous stream. By means of the record blobs groups can bring material quickly enough.
"The rapid dissipation of the record is not something I expected," Grady said. "Based on the brightest star-based discs, we expected the brightest red dwarf to have a longer disk drive," the AU Mic was likely to start with the edge of some small ice bodies, like the Kuiper belt found on our solar system . If this disk had not been defused, it would be split into the inner planet dry.
Blob Mystery probing
Hubble astronomers have seen blocks in images of visible light in STIS 2010-2011. As a follow-up to the Hubble studio, the SPHERE (Spectro-Polarimetric Contrast Exoplanet Research) mounted in the Southern European Observatory of Space Telescope was closely monitored by infrared observation. The features of the record were highlighted in the observations taken in 2004, ground-based telescopes and Hubble's Advanced Surveys Camera.
Until now, the team has revealed the blobs of the Southeast of the disk, estimated at speeds of 9,000 and 27,000 miles per hour, quickly enough to escape the gravitational clutter of the stars. Currently, they have a distance of more than 930 million miles from 5.5 million more than the star.
Hubble also shows that balls can be giant with dusty exposure. The telescope resolved the infrastructure in a blobs, including a spin-off plate and a loop-like complex that is under the disk. "These structures explain the mechanisms that encourage traces," said Schneider.
"AU Mic is well positioned," said Schneider. "But there are only three or four red-dwarf systems with well-known star clusters. The other well-known systems are six times more remote, so the exact analysis of the characteristics of these discs that we see in AU Microscope is a challenge".
However, astronomers are beginning to detect some of the similarities to other systems. "AU Mic does not show only one," Grady said. "In fact, you can argue that it is one of the closest kind of this type of system, and it would not be the only one."
AU Mic's observations show the importance of the formation and evolution of the planet on the record of a star. "What we have learned is that the record seems to be part of the history of planetary systems," Grady said. "If you do not understand a star's disc, you do not understand the planet's system well".
