Global storms on Mars launch dust towers 80 km (50 miles) into the sky

When a massive dust storm on Mars– like the one in 2018– reaches its full potential, it can transform into a globe-bestriding colossus. This happens often on the red planet, and these storms typically start out as a sequence of smaller storms. NASA scientists said…

Asteroid Hygiea the smallest dwarf planet in the solar system

Hygiea, previously classified as an asteroid, may actually be the smallest dwarf planet in the solar system, according to a study published on October 28, 2019. New images by the ESO's SPHERE instrument at the Very Large Telescope (VLT) revealed that the space…

Eugene Bagashov: Martian geology, past and present

Eugene Bagashov: Martian geology, past and present

In part one of this presentation, physicist Eugene Bagashov began his examination of some of the enduring geological mysteries on Mars. Of course, geologists examining the surface of Mars project familiar earthly processes onto the Red Planet — they imagine…

The comet Venus and its missing craters

The comet Venus and its missing craters

Since the dawn of the Space Age, the planet Venus has been a proving ground for competing hypotheses in planetary science. From the 1950s to 1970s, Venus was at the center of a blazing scientific controversy. In 1950, in the bestselling book Worlds in Collision, the…

Martian dust storm now officially a global dust event

Martian dust storm now officially a global dust event

One of the most intense dust storms ever observed on Mars is raging across the planet since May 30, 2018. The storm grew rapidly over the next 20 days and is now officially a 'planet-encircling' (global) dust event. Although Martian dust storms are common…

Rapidly intensifying, possibly planet-wide dust storm affecting Mars

Rapidly intensifying, possibly planet-wide dust storm affecting Mars

A massive and intensifying dust storm, one of the most intense ever observed on Mars, is affecting the Red Planed since May 30, 2018. The storm is growing rapidly and is likely to go, or has already gone, global. On June 10, the storm covered more than 41 million…
