Over the last month, ESA’s Mars Express has been watching dust storms brew at the planet's north pole and disperse toward the equator.

Satellite images confirm that this rare lava lake is a continuous feature at the top of Mount Michael, in the South Atlantic's South Sandwich Islands. The temperature of the molten lava is some 1,000 degrees Celsius (1,800 degrees Fahrenheit).

Move over, Tabby's Star. The Random Transiter may now be the weirdest star in the galaxy. Kepler data revealed 28 transits in front of this star in 87 days. What caused them? Multiple planets? A disintegrating planet? Alien megastructures?

Supercomputer simulations of galaxies show that Einstein’s general theory of relativity might not be the only way to explain how gravity works or how galaxies form. The new Chameleon Theory is a possible alternative.

Here be monsters. This video shows a living giant squid, captured on camera in its natural habitat for only the 2nd time in history.

This series of photos from Eliot Herman shows the progress of the moon's shadow during the July 2, 2019, total solar eclipse in Chile.

No, it’s not pseudoscience. Does a regular alignment of planets make a strong-enough tug to regulate the sun’s 11- and 22-year cycles? Read more in this story via Eos - a source for news and perspectives about Earth and space science - from the American Geophysical Union.

An earthquake scientist said of the recent 2 big California earthquakes, "... the M6.4 was a foreshock. This was a M7.1 on the same fault ... part of the same sequence." She added it will not trigger another large earthquake outside the Ridgecrest, California, area.

Scientists have been trying to figure what creates the so-called "bathtub rings" around lakes and seas on Saturn's large moon Titan. Now they may have an answer: unusual organic crystals not found on Earth.

Some called it the "astronomer's eclipse" because it passed near major observatories in Chile. Check out these beautiful images of the July 2, 2019, total solar eclipse.
