A robot submarine could explore Titan’s deepest sea

A new study of data from NASA's bountiful Cassini mission shows that Titan's largest methane sea, Kraken Mare, is at least 1,000 feet - 300 meters - deep near its center. That's plenty of room for a future robotic submarine to explore.

New evidence for multiple ice ages on Mars

Earth has had at least 5 major ice ages. Now it appears Mars - the next planet outward from the sun - has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years.

Striped brown dwarf looks a lot like Jupiter

The surface features of brown dwarfs - objects midway in mass between planets and stars - can't be seen. But researchers have found a way to reveal Jupiter-like stripes and bands in the atmosphere of the closest brown dwarf, Luhman 16B.

Hostile space weather might not be all bad for exoplanet life

A new study from Northwestern University shows that solar flares - space weather - might not always be as dangerous for life on exoplanets as typically thought. In fact, it might even help astronomers discover alien life on distant worlds.

Dark storm on Neptune changes direction, escapes deadly fate

Astronomers used the Hubble Space Telescope to observe unusual weather on the planet Neptune, not observed until now. They saw a large, dark storm on Neptune unexpectedly changing direction, thereby saving itself from looming destruction and possibly producing a smaller companion storm.

Paul Scott Anderson

Paul Scott Anderson has had a passion for space exploration that began when he was a child when he watched Carl Sagan’s Cosmos. He studied English, writing, art and computer/publication design in high school and college. He later started his blog The Meridiani Journal in 2005, which was later renamed Planetaria. He also later started the blog Fermi Paradoxica, about the search for life elsewhere in the universe. While interested in all aspects of space exploration, his primary passion is planetary science and SETI. In 2011, he started writing about space on a freelance basis with Universe Today. He has also written for SpaceFlight Insider and AmericaSpace and has also been published in The Mars Quarterly. He also did some supplementary writing for the iOS app Exoplanet. He has been writing for EarthSky since 2018, and also assists with proofing and social media.
