ANU astrophysicist and cosmologist Dr Brad Tucker says astrophysicists have determined Earth to be in one of the best places in the galaxy for preserving life as there is a low chance of being affected by star explosions.

“This is actually quite important, we talk a lot about trying to find planets about other stars to try and look for life but we know lots of things happen in the galaxy that could end that life,” he told Sky News.

Dr Tucker said star explosions occur once every five seconds and emit harmful radiation and energy which can kill lifeforms on nearby planets.

“When these stars explode they produce lots of radiation and energy that can actually wipe out lifeforms in a surrounding area so in the galaxy astronomers mapped out where are the quiet places, essentially where are the safest places away from these explosions.”

“Unsurprisingly it happens that we are in one of those great locations in our galaxy.”
