Fascinating stars, black holes, suns, moons WOW!

A Slight Detour

Scientists believe this to be the largest hole in the ozone layer ever recorded.

The hole covers an area roughly three times the size of Greenland.

It can expose people living at far northern latitudes to high levels of ultraviolet light radiation.

It appears that it will close on its own in a few weeks an ESA researcher stated.

And another detour

If this supervolcano erupts it will cause massive destruction. It has only erupted 3 times before: 2.1 million years ago, 1.3 million years ago, and 640,000 years ago.

Sorry for the detours but these were events of great significance if they complete configurations. The earthquake at Yellowstone registered 7.5 magnitudes.
