By the year 2020 in the simulation, 17% of the Earth's protective ozone layer vanished. Holes in the ozone layer formed not just over Antarctica—as they currently do each spring—but over the Arctic, ...

Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure. The hole in the ozone layer over Antarctica is now larger than the North American continent.

Black holes may not be as life-destroying as we thought. A surprising study reveals that the powerful radiation from active ...

ozone is a naturally occurring gas that acts as a sort of sunscreen, protecting the planet from the sun's harmful ultraviolet radiation. In 1985, scientists discovered a "hole" in the ozone layer ...

The ozone layer is a thin shield of gas in the Earth’s atmosphere that protects the planet, absorbing the sun’s ultraviolet (UV) rays and helping to preserve all life on the planet.

Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in ...

Often seen as destructive, supermassive black holes could help sustain life under specific conditions, scientists have found.

The ozone layer is a crucial component of Earth's stratosphere, located between 19 and 30 km above the surface. It plays a vital role in filtering harmful ultraviolet (UV) radiation from the sun ...

Here’s why that’s a problem: The ozone layer is a region in the stratosphere that absorbs harmful UV light from the sun. It’s basically our planet’s natural sunscreen. And it had grown ...

It worked. Today, the ozone hole is showing signs of recovery. We have avoided a future in which unfiltered UV radiation from the sun would cause millions of cases of skin cancer. For those at the ...
