NASA captures first snapshop of planet outside our solar system

NASA has used the Hubble Space Telescope to capture the first visible-light image of a planet circling another star. The planet, called Fomalhaut b, is estimated to be approximately three times Jupiter's mass and takes roughly 872 years to orbit the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis. About 300 extrasolar planets have been discovered through indirect observations (e.g. by obstructing the light of stars) but this is the first to be viewed directly.

Spacecraft to probe edge of solar system

LOS ANGELES, California (AP) -- A small NASA spacecraft embarks on a two-year mission this weekend to give scientists their first view of the happenings at the edge of the solar system.
NASA hopes its new Ibex probe will help explain why the sun's protective heliosphere is shrinking.

The Ibex probe, short for Interstellar Boundary Explorer, will study a chaotic region in space where the solar wind from the sun clashes with cold gases from interstellar space.

Solar System Mysteries

We've all wondered at some point or another what mysteries our Solar System holds. After all, the eight planets (plus Pluto and all those other dwarf planets) orbit within a very small volume of the heliosphere (the volume of space dominated by the influence of the Sun), what's going on in the rest of the volume we call our home?
