A supernova that erupted when a massive star died could have destroyed our infant solar system — if it weren't protected by a cocoon of molecular gas. When you purchase through links on our site, we ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the ...

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially ...

A new explanation for the solar system's radioactive elements suggests Earth-like planets might be found orbiting up to 50 ...

A supernova that exploded close to our newly forming sun could have destroyed what became our solar system — if it weren't for a shield of molecular gas. Scientists reached this conclusion by studying ...

New work offers fresh evidence supporting the supernova shock wave theory of our solar system’s origin. According to one longstanding theory, our Solar System’s formation was triggered by a shock wave ...

A very strange meteorite found in western Egypt in 1996 may have tiny pieces of the debris from a supernova in it, and not just any supernova but one created by the explosion of a white dwarf, the ...

Ion probe studies and improved stellar nucleosynthesis models are providing new insights into our solar system's stardust Until recently, cosmochemists and astrophysicists assumed that supernovae and ...

If the Sun was born in a relatively compact open cluster (half-mass radius ~3pc) with ~10^3 stars, it is quite likely that a massive (>10MSun) star was nearby when it exploded in a supernova. The ...

The blast from a supernova should be enough to clear almost all the dust from the solar system, and this may have last happened 3 million years ago. But like the dust on furniture, these fine ...

(Nanowerk News) Until recently, cosmochemists and astrophysicists assumed that supernovae and their progenitors, the supergiant stars, contributed only little of our solar system’s stardust content.
