Using NASA's Interstellar Boundary Explorer (IBEX), scientists have devised the best model yet for the appearance of a vast ribbon of neutral atoms that curls through the boundaries of Earth's solar system.
Scientists compile data from IBEX, Voyager, and computer models to show that the heliosphere just isn't moving fast enough to create a bow shock.
On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward Earth; two NASA Heliophysics System Observatory Missions observed the storm from complementary viewpoints.
It's an alien environment out there: the material in the galactic wind doesn't look like the same stuff our solar system is made of.
Special cameras aboard the Interstellar Boundary Explorer, or IBEX, spacecraft have snapped the first images of space weather as it happens.
NASA's IBEX spacecraft, designed to image the invisible interactions occurring at the edge of the solar system, captured images of magnetospheric structures and a dynamic event occurring in the magnetosphere as the spacecraft observed from near lunar distance.
When Interstellar Boundary Explorer (IBEX) was launched on October 19, 2008, space physicists held their collective breath for never-before-seen views of a collision zone far beyond the planets. Now scientists have finished assembling a second complete sweep around the sky, and IBEX has again delivered an unexpected result: the map has changed significantly.
It wasn’t until the IBEX mission that they’ve been able to see what the human eye cannot: the first-ever images of this electromagnetic crash scene.
Last year, when NASA's IBEX spacecraft discovered a giant ribbon at the edge of the solar system, researchers were mystified. They called it a "shocking result" and puzzled over its origin. Now the mystery may have been solved.
The magnetic field surrounding our solar system acts like a mirror for the particles that IBEX sees.
The IBEX mission science team has constructed the first-ever all-sky map of interactions occurring at our solar system's edge, where the sun's influence wanes.
For the first time, space physicists are building a comprehensive picture of the interactions taking place in the outer solar system—called the interstellar boundary—using particles detected by NASA's Interstellar Boundary Explorer (IBEX).
A new NASA mission that explores the outer edges of our solar system is featured at the Adler Planetarium and Science Museum in Chicago.
IBEX will build an image of the outer boundary of the solar system from impacts on the spacecraft by high-speed particles called energetic neutral atoms.
NASA will hold a media teleconference on Friday, Oct. 17, at 1 p.m. EDT, to preview the Interstellar Boundary Explorer, or IBEX, mission.
