Latest Heliosphere Stories
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.
NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space.
NASA's Voyager 2 has successfully switched to the backup set of thrusters that controls the roll of the spacecraft.
NASA's Deep Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft.
Those who study the sun face an unavoidable hurdle in their research â€“ their observations must be done from afar. Relying on images and data collected from 90 million miles away, however, makes it tough to measure the invisible magnetic fields sweeping around the sun.
NASA said Wednesday that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought.
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...
