Has Voyager 1 Finally Left The Solar System? New Analysis Reveals Compelling Evidence
2013-08-15 13:47:59

Brett Smith for redOrbit.com - Your Universe Online According to a new analysis from scientists at the University of Maryland, NASA's Voyager 1 has finally left the Solar System – marking the first time a man-made object has entered the Milky Way outside of the Sun’s influence. "It's a somewhat controversial view, but we think Voyager has finally left the Solar System, and is truly beginning its travels through the Milky Way," said study author Marc Swisdak, a UMD plasma physicist....

IBEX First Images Heliosphere Tail

[ Watch the Video: IBEX Provides First View of the Solar System’s Tail ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Interstellar Boundary Explorer (IBEX) spacecraft has unveiled an unexpected structure in the first complete pictures of the solar system's heliotail. Scientists believe a "tail" trails the heliosphere, which is the giant bubble in which our solar system resides. As the heliosphere moves through interstellar space, it creates a tail similar to that of a...

Voyager 1 Still Within The Confines Of Solar System

Lee Rannals for redOrbit.com - Your Universe Online Scientists are split on exactly where NASA's Voyager 1 spacecraft is sitting within the Solar System, but new research from the space agency suggests it is on the last frontier out. A team of scientists wrote in Geophysical Research Letters in March that the spacecraft had already left our Solar System. However, the latest intel from NASA shows that the spacecraft is still sitting just within the edge of our "Solar Bubble."...

NASA's Jet Propulsion Laboratory A gauge on the Voyager home page tracks levels of two of the three key signs scientists believe will appear when the spacecraft leave our solar neighborhood and enter interstellar space. When the three signs are verified, scientists will know that one of the Voyagers has hurtled beyond the magnetic bubble the sun blows around itself, which is known as the heliosphere. The gauge indicates the level of fast-moving charged particles, mainly protons,...

Voyager 1 Continues Its Journey

Lee Rannals for redOrbit.com - Your Universe Online NASA´s Voyager 1 spacecraft may have allegedly left the confines of our solar System after 35 years and more than 11 billion miles of traveling through space. Scientists writing in the Geophysical Research Letters claim that they measured drastic changes in radiation levels on August 25, 2012 while the spacecraft was sitting over 11 billion miles away from the Sun. The anomalous cosmic rays (those trapped in the outer heliosphere)...

Voyager 1 Enters New Region Of Deep Space
2012-12-03 14:41:16

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online NASA announced at the American Geophysical Union meeting in San Francisco on Monday that its Voyager 1 spacecraft has reached a region of space no other spacecraft has reached before. After 35 years, the Voyager 1 spacecraft has reached a new region of deep space known as a magnetic highway for charged particles. In this region, our sun's magnetic field lines are connected to interstellar magnetic field lines....

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
