Supernova Light Could Be Risk to Life on Earth


www.foxnews.com

An explosive star within our galaxy is showing signs of an impending eruption, at least in a cosmic time frame, and has for quite some time.

From 1838 to 1858, the star called Eta Carinae brightened to rival the light of Sirius, the brightest star in the sky, and then faded to a dim star.

Since 1940 it has been brightening again, and scientists think Eta Carinae will detonate in 10,000 to 20,000 years.

Fortunately, Eta Carinae is far away, at least 7,500 light-years from Earth. If it explodes, most of its energy will be scattered or absorbed in the vast emptiness of space.

Eta Carinae is brightening again and may supernova within 10,000-20,000 yrs. It is far enough away and located on an angle so the cosmic rays released will not damage earth. Magnetic fields around earth (and sun) normally reduce the danger from cosmic rays.
