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.
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.
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.
Hurtling through space at more than 35,000 miles per hour, NASA’s Voyager 1 is on the verge of breaking the barrier between the known Solar System and Interstellar Space
Celebrating its 35th anniversary in space today, NASA’s Voyager 1 spacecraft is about to cross the threshold of our solar system, to boldly go where no man, nor machine, has ever gone before.
Monday marked the 35 year anniversary of NASA's Voyager 2 spacecraft launching from Earth, and embarking on a venture to go where no spacecraft has gone before.
New report presents research program for solar and space physics over the next decade.
After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space.
A team of NASA researchers has uncovered new data showing that the sun is moving more slowly through our galaxy than previously believed -- a discovery that suggests a shock wave believed to precede the heliosphere might not actually exist.
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...
- Any of various tropical Old World birds of the family Indicatoridae, some species of which lead people or animals to the nests of wild honeybees. The birds eat the wax and larvae that remain after the nest has been destroyed for its honey.
