Scientists Solve Mystery Surrounding Voyager 1's Passage to Interstellar Space

Ever since NASA’s Voyager 1 spacecraft exited the heliosphere and made the passage to interstellar space, scientists were perplexed by the spacecraft inconsistent measurements of the galactic magnetic field that lies outside of the Sun’s magnetosphere. A new study shows that these inconsistencies are caused by the deflection of the galactic magnetic field […]

Comet ISON—or whatever is left of it—is fading fast, and the latest images from the NASA/ESA Solar and Heliospheric Observatory (SOHO) LASCO-C3 camera may be […]

Ghost of Comet ISON Rises Like an Icy Phoenix After Suicidal Kamikaze Visit With the Sun

ISON appears as a white smear heading up and away from the Sun. ISON was not visible during its closest approach to the Sun, so many scientists thought it had disintegrated, but images like this one from the ESA/NASA Solar and Heliospheric Observatory suggest that a small nucleus may be intact.

All Eyes on Comet ISON as It Plummets Toward Thanksgiving Day Brush With the Sun

VIDEO: Comet ISON moves ever closer to the Sun in this movie from the ESA/NASA Solar and Heliospheric Observatory, captured in the early hours of Nov. 27, 2013. A coronal mass ejection explodes off the Sun; it is unlikely to damage ISON even if they cross paths. Image Credit/Caption: ESA/NASA/SOHO
