THE LATEST IN THE GEOSCIENCES
A new fossilized arthropod that lived in British Columbia over 500 million years ago was recently described. One unique aspect of this new creature is the scissor-like claws that it had.
The researcher that described this new species, David Legg, noted that these claws were reminiscent of the hands of the main character in the 1990 movie “Edward Scissorhands,” played by Johnny Depp.
Legg, being a fan of Johnny Depp, gave this actor a polite nod by naming the new species after him: Kooteninchela deppi.
On March 17, a meteorite crashed into the Moon’s surface resulting in a new crater about 65 feet wide. There was an explosion caused by this impact that would have been visible to anyone observing the Moon at that time.
It isn’t often we are able to actually observe impacts occurring on other celestial bodies. This one is significant, as it demonstrates one of the potential risks to astronauts working on the Moon.
Mount Pavlof is a volcano that forms part of the Aleutian Islands chain. The Aleutian Islands are all volcanic, and have formed due to the subduction of the Pacific Plate beneath the North American Plate (which includes Alaska).
The Pavlof volcano began to erupt on May 13, shooting streams of ash and lava into the air. As yet, it has not caused any problems with air travel, though pilots have been told to exercise caution in the area. If Pavlof really goes off, it could have a great impact on international air travel.
