- We’ve found that ozone in the atmosphere could have been destroyed, ultraviolet light from the Sun could have harmed life on the surface, and high-energy cosmic rays could have rained down, increasing the radiation dose for all life on Earth and especially large animals in the oceans.

May 8, 2024 · A supernova less than 50 light-years away could end all life on Earth, while one 100 light-years away would have drastic consequences. No massive stars expected to become supernovae are within 50 light-years of the Sun currently.
If you were in a Supernova you would see many different colors flying everywhere, this is because the Star is releasing gases of many types. You would also see the star get literally pulled apart, and parts flying everywhere. If the star is close enough then parts of the star could land on Earth!
Study with Quizlet and memorize flashcards containing terms like Describe a supernova., Name two types of supernovas and briefly describe the events that happen in each case., Name and describe the leftovers from a supernova (expanding gas cloud and neutron star). and more.
Jan 6, 2022 · A remarkable link between the number of nearby exploding stars, called supernovae and life on Earth has been discovered. A study demonstrates a link between supernova frequency and the burial of organic matter in sediments, influencing Earth’s climate, nutrient cycles, and bioproductivity.

In 1954, Otto Heinrich Schindewolf, a German paleontologist, speculated that at least one of the great mass extinctions seen in the history of life on Earth might have been caused by a nearby exploding star, but it wasn’t until the 1970s that scientists began trying to put together a realistic picture of what might happen on Earth if a supernova we...
Not long after Ellis, Fields, and Schramm proposed this way of detecting a supernova in Earth’s geologically recent history, a team of German scientists reported the first detection of just a few atoms of iron-60 in a drill core from the ocean floor. The atoms came from a section of sediment determined to be about 2.5 million years old. The same te...
What we found was both familiar and surprising. First, we examined how the light from the supernova would affect Earth. While most work in the past has examined how high-energy X-rays would affect the atmosphere, we found that there wouldn’t be enough energy in this kind of light from the event 2.5 million years ago. While we didn’t find much effec...
