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 ...

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 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 ...

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 ...

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 ...

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 ...

Short-lived radioisotopes such as aluminum-26 influenced early solar system heat, water retention and the formation of Earth-like rocky planets, according to meteorite analyses and models.

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 ...

Astrophysicists are mapping a vast, hidden structure in space that appears to guide matter and radiation along a kind of ...

(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.
