Fantastic Voyager


Fat bum, fantastic vessel Voyager 1 was launched over 35 years ago! Now it is 11.5 million miles from Earth, and is fast on its way out of our solar system and the mysterious region beyond the family of our Sun - the cold, dark space between the stars. In June 2013, astronomers announced that this abundant ship entered a strange new kingdom located within the confines of our solar system - which indicates that it is about to break free from the clutches of its parent star, and on the point of going into outer space!

It has been 36 years since the release of the Voyager 1 and its sister ship, Voyager 2. Voyager 2 was the first spacecraft to make a long and dangerous journey to the distant kingdom of beautiful and dazzling blue-green, ice planets distance giants, Uranus and Neptune. Voyager 1 was launched 16 days after her sister ship, and both beautiful and venerable homeless are still there exploring, streaking away from his father-star, the Sun, compress away to freedom beyond the limits of our solar system. Scientists have long been waiting breathlessly when the business on the other side, tearing into interstellar space. May not have to wait longer.

Dr. Ed Stone told reporters August 21, 2012, on the occasion of the 35th anniversary of the launch of Voyager 2, that "even 35 years, our robust probe Voyager are about to make new discoveries as we await the signs we entered into interstellar space. "Mr. Stone is Voyager project scientist at the California Institute of Technology (Caltech) in Pasadena, California. He added that" the results returned Voyager Jupiter and Saturn in worlds tumultuous complete, weaknesses moons in separate places, and gave us the first glimpses of Uranus and Neptune nearby. We can not wait to bring our Voyager models of the space beyond our sun into the first observations of interstellar space. "

Breaking Free!

Since summer 2012, Voyager 1 has been exploring unknown regions, where the effects of the mysterious space between interstellar space stars-- - can last be experienced. Astronomers do not know how extensive is this new area on the outskirts of our solar system - and therefore do not know how much further Voyager 1 to travel free of the obligations of the parents of our Sun, and finally have a life across!

June 27, 2013, astronomers hope announced that, no, the Voyager 1 had not yet free floated its solar ties in interstellar space, but had managed to reach a foreign field that no one had expected - and no one can love but really explain. This newly discovered region is a strange place, and it is almost certain that the influence of parents of our Sun is his last fight - technically speaking, is the heliosphere. Both Voyagers are studying the outer layers of the heliosphere, a huge bubble of charged particles and magnetic fields around our star. But things get really weird for Voyager 1 and zips through this strange place, and its outer limits.

"In fact, it could be any time or it could be several years," said Dr. Pierre journalists June 27, 2013.

Mr. Stone was first announced the existence of this strange and unexpected region on a the American Geophysical Union meeting in 2012. Three articles published June 27, 2013 in the online edition of the journal Science described how strange this new area is dark.

August 25, 2012, Voyager 1 recorded a decrease of 1 000 times the number of charged particles from the sun - while measuring an increase of 9 percent in quickly compress particles called cosmic rays from the galaxy.

These are two of three phenomena that astronomers should see when the ship finally passes into the space between the stars. "It seemed like we were outside," said Mr. Stone June 28, 2013, the New York Times.

However, Voyager 1 has not yet experienced the third phenomenon, which is a change in the direction of the magnetic field, from east to west in the north-south about solar beyond his system.

The magnetic field "does not change direction. All I did was compressed, so it is stronger than it was. This is what one would expect if, indeed, energetic particles who provided the pressure suddenly they are gone, "Dr. Pierre told the press June 27, 2013.

Scientists guess that Voyager 1 is still trapped in the magnetic field of the sun, but in a strange region where you are now, magnetic fields in our solar system are linked in part to interstellar space. This allows to escape from the solar particles - the charged particles travel along magnetic field lines is due. Astronomers call this region found strange Twilight Zone - through which the Voyager 1 is now traveling - exhaustion heliopause region. Therefore, Voyager 1 explores some sort of connection with the interface heliosphere area interstellar space.
