As long as ISON is a fairly typical comet — one with "normal" size, density and rotational characteristics — it probably won't disintegrate during its upcoming close solar encounter on Nov. 28.

An artist’s conception of a planet’s magnetosphere interacting with a stellar wind. The result is a clear blow shock, seen as the dark blue bubble. Image credit: NASA Astronomers may soon be able to observe the shockwaves between the magnetic fields of exoplanets and the flow of particles from the stars they orbit. Magnetic fields are crucial to a planet’s (and as it turns out a moon’s) habitability. They act as protective bubbles, preventing harmful space radiation from stripping away the object’s atmosphere entirely and even reaching the surface.

Artist’s conception of Juno coming near Earth on a planned flyby Oct. 9, 2013. Credit: NASA Every so often, engineers send a spacecraft in Earth’s general direction to pick up a speed boost before heading elsewhere. But sometimes, something strange happens — the spacecraft’s speed varies in an unexpected way. Even stranger, this variation happens only during some Earth flybys.
