Possible Planetary Disasters That Could Cause Extinction

Planetary-Disasters-That-May-Cause-Extinction

In the last 40,000 years, there have been at least ten gigantic landslides of more than 100 cubic kilometers in the North Atlantic ocean alone. Each of these was capable of producing waves tens to hundreds of meters in height and according to a new report, this is only one of the many possible planetary disasters that could cause extinction.

Saturn-Like Rings May Have Formed Solar System’s Moons

Moons of Solar System Might Have Been Formed From Saturn-Like Rings

Earth’s moon might have emerged from a long-vanished ring system, akin to the rings still encircling Saturn, and this could apply to many of the satellites orbiting other planets. The bulk of the regular satellites in the Solar System might have formed this way, instead of taking shape simultaneously with the planet as a direct result of planet formation.

Impact May Have Deformed Saturn’s Moon Iapetus

One of the strangest moons in the Solar System is Saturn’s Iapetus, which features an enormous equatorial mountain ridge and spiky belt that rises 12 miles above the moon’s surface may have all been the result of a single impact.

Most orbiting satellites point down towards Earth, but the satellites of the Constellation Observing System for Meteorology look sideways. Ionosphere and Climate (COSMIC) look towards the curving horizon in order to track the dozens of satellites that are part of the Global Positioning System. By tracking their radio signals, COSMIC is providing atmospheric data that enhances weather forecasts and climate models.
