Latest Heliosphere Stories
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.
ESA has awarded the contract to build its next-generation Sun explorer to Astrium UK. Solar Orbiter will investigate how the Sun creates and controls the heliosphere, the extended atmosphere of the Sun.
Researchers announced the finding at a press conference on Jan. 31, 2012. It’s based on data from NASA’s IBEX spacecraft, which is able to sample material flowing into the solar system from interstellar space.
Researchers, uding NASA's Interstellar Boundary Explorer (IBEX) spacecraft, have measured neutral "alien" particles that have entered our solar system from interstellar space.
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...
