NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic purgatory.

Scientists have found a recipe for cooking the solar system from scratch: take a cold cloud of gas, and set it 15 light-years from an exploding supernova. Stun the cloud with the supernova’s shockwave. Incubate, and watch as the solar system begins to take shape.

Computer model confirms that our Solar System was born from the ashes a dead star.
Interesting read on how our solar system was born. Among the different hypothesis, a simulation seems to favor the one of a supernova. Via Guillaume Decugis

We seem to be inside a "local bubble" in a network of cavities in the interstellar medium, probably carved by massive star explosions millions of years ago. The interstellar medium (or ISM) is the matter that exists in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, dust, and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space.

Peaking under the thick atmosphere using Cassini's Visual and Infrared Mapping Spectrometer, an international team has composed a global color map of Titan. This mosaic was compiled from imagery taken over seventy flybys of Saturn's largest moon.
