A Chicago Meteorite Fall
24.07.2005

If you wait long enough, a piece of outer space itself will come right to you. As Colby Navarro worked innocently on the computer, a rock from space crashed through the roof, struck the printer, banged off the wall, and came to rest near the filing cabinet.

The Largest Impact Crater
6.09.1996

What is the largest known impact crater in the Solar System? Over 1300 miles across, the South Pole-Aitken Basin on the farside of Earth's Moon holds that distinction. Circled above in a false color mosaic of Clementine images it was caused when an asteroid or comet sized object crashed

What's that cloud drifting in space? It's not an astronomical nebula -- those appear to stay put. Atmospheric clouds don't look like this. The answer to last week's sky mystery turned out to be orbiting and expanding debris from the upper stage of a failed Russian rocket that exploded unexpectedly.

Lightning Storm Moves Across the USA
15.05.2017

Watch a huge lightning storm move across the eastern USA. The huge storm caused much damage and unfortunately some loss of life for people in its path. Seen from space, the lightning is seen as momentary flashes in the featured time-lapse video recorded last month by the Geostationary Lightning Mapper (GLM) aboard the GOES-16 satellite.

The Gator Back Rocks of Mars

Wind-sharpened rocks known as ventifacts, cover this broad sloping plain in the foot hills of Mount Sharp, Gale crater, Mars. Dubbed gator-back rocks their rugged, scaly appearance is captured in these digitally stitched Mastcam frames from the Curiosity rover on mission sol 3,415 (March 15, 2022).

Tornadoes on the Sun
29.04.1998

Giant spinning clouds of gas, similar to Earth's tornadoes, have been found on the Sun. Solar tornadoes, however, can be larger than the entire Earth, and sustain wind gusts over 1000 times stronger than their Earth counterparts.

Hurricane Ivan from the Space Station
9.10.2016

Ninety percent of the houses on Grenada were damaged by the destructive force of Hurricane Ivan. At its peak in 2004, Ivan was a Category 5 hurricane, the highest power category on the Saffir-Simpson Scale, and created sustained winds in excess of 200 kilometers per hour.

A Galaxy Collision in NGC 6745
2.11.2000

Galaxies don't normally look like this. NGC 6745 actually shows the results of two galaxies that have been colliding for only hundreds of millions of years. Just off the above photograph to the lower right is the smaller galaxy, moving away.

Above the Eye of Hurricane Ivan
15.09.2004

Ninety percent of the houses on Grenada were damaged. Such is the destructive force of Hurricane Ivan, already one of the most powerful and destructive hurricanes on record. And the storm will likely make landfall in southern USA tomorrow.
