Join online as leading space scientists discuss the legacy of Apollo 11 during the mission's 50th anniversary this week.

The total solar eclipse of August 22, 1142, may have coincided with the birth of the Iroquois Confederacy, oldest democracy in North America and possibly on Earth.

Scheduled for launch in 2026, the Dragonfly mission will look for clues to the origins of life, and possibly even evidence of life itself, on Saturn's alien yet remarkably Earth-like moon Titan.

The newly-discovered rocky body - dubbed 2019 LF6 - orbits the sun roughly every 151 days.

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.

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.

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.

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.

The rings of the 7th planet, Uranus, are thin and dark. But new thermal images from the ALMA and VLT telescopes show them glowing brightly.
