Evidence from daughter products of short-lived radioactive isotopes shows that a nearby supernova helped determine the composition of the Solar System 4.5 billion years ago, and …

Dec 28, 2016 · The explosive death of a star — that may have been up to a dozen times the sun's mass — might have triggered the formation of the solar system, a new study finds.

Jan 10, 2024 · Will our Sun ever explode in the dazzling display of light known as a supernova? Scientists say no, for two major reasons.

Radioactive isotopes found in meteorites suggest a supernova went off right near the Sun as it was forming – but that should have blasted the young solar system away. So how did we …

Aug 23, 2012 · Remnants of an isotope of iron in the meteorites could have come from a distant massive star that died in a violent, luminous explosion, called a supernova. Some scientists …

Jul 4, 2023 · So why did the Solar System survive? The gas within the filament seems to be able to protect it from the supernova and its onslaught of radioactive isotopes.

Jun 30, 2023 · A study suggests that a nearby supernova explosion enriched the early Solar System with radioactive isotopes while a dense molecular filament protected it from destruction.

Jun 17, 2025 · They found that a supernova could have blasted radioactive elements into the cloud of dust that surrounded our young sun, triggering a shock wave that caused the cloud to …

Apr 21, 2025 · Our solar system is quietly nestled within a peculiar region of space known as the Local Bubble—a massive, roughly spherical region nearly 1,000 light-years across, distinctly …

Oct 1, 1978 · Isotopes found in a few primitive meteorites are probably debris from a massive star that apparently exploded near the developing solar system about a million years before the …
