Award-Winning Photo Captures The Grisly Spectacle of Starfish Swarming to Feed

Award-Winning Photo Captures The Grisly Spectacle of Starfish Swarming to Feed

An award-winning photographer has captured the somber moment when dozens of colorful starfish set about devouring a lifeless sea lion on the seafloor in California. Wildlife photographer David Slater captured the haunting photo in the shallow waters of Monterey Bay. The dead sea lion and its compatriots swimming in the background are most likely California … Read more

Strange Honeycomb Pattern on Mars Appears to Be Formed by Water Ice And CO2

Strange Honeycomb Pattern on Mars Appears to Be Formed by Water Ice And CO2

From orbit, this landscape on Mars looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren’t created by Martian bees or spiders; they are actually formed from an ongoing process of seasonal change from created from water ice and carbon dioxide. The HiRISE camera (High Resolution Imaging Science Experiment) on … Read more

Astronomers Unveil The Most Detailed Map of The Metal Asteroid Psyche Yet

Astronomers Unveil The Most Detailed Map of The Metal Asteroid Psyche Yet

If you wanted to do a forensic study of the Solar System, you might head for the main asteroid belt between Mars and Jupiter. That’s where you can find ancient rocks from the Solar System’s early days. Out there in the cold vacuum of space, far from the Sun, asteroids are largely untouched by space … Read more

New Images Show The Dust in Nearby Galaxies, And You’ve Never Seen Them Like This

New Images Show The Dust in Nearby Galaxies, And You’ve Never Seen Them Like This

When we see pictures of galaxies outside the Milky Way, what we’re usually looking at is primarily the light of their stars. But stars are far from the only ingredient that makes up a galaxy. Think of stars as the chunks of vegetables in the galactic soup. The broth, then, in which they float, is … Read more

New Image of Mars Reveals a Crater Eerily Similar to a Huge, Creepy Eye

New Image of Mars Reveals a Crater Eerily Similar to a Huge, Creepy Eye

A new image snapped by a spacecraft orbiting Mars could be enough to give one Lovecraftian nightmares. Far below the camera of ESA’s Mars Express, a large, city-sized, unnamed crater gapes on the surface of the red planet, smears of dark material making it appear like an enormous eye gazing out to the stars. Yet … Read more

New Study Suggests That a Young Jupiter Gobbled Up Plenty of Planetesimals

New Study Suggests That a Young Jupiter Gobbled Up Plenty of Planetesimals

Jupiter is composed almost entirely of hydrogen and helium. The amounts of each closely conform to the theoretical quantities in the primordial solar nebula. But it also contains other heavier elements, which astronomers call metals. Even though metals are a small component of Jupiter, their presence and distribution tell astronomers a lot. According to a … Read more

A Hitchhiking Rock Has Traveled With The Perseverance Rover For More Than 120 Days

A Hitchhiking Rock Has Traveled With The Perseverance Rover For More Than 120 Days

Roaming Mars is a lonely existence for NASA’s Perseverance, but the exploratory rover now has a traveling companion: a hitchhiking “pet rock” that got stuck in one of its wheels. Luckily, the Martian stone won’t impact the rover’s science mission and is only a minor inconvenience – like having a pebble stuck in your shoe. … Read more

Your Brain Is Ready to Learn About New Things Without You Even Realizing

Your Brain Is Ready to Learn About New Things Without You Even Realizing

Simply being exposed to things we’re not familiar with – new objects or species of animals, for example – puts us in learning mode, new research has revealed, and makes us more ready to learn about the new thing later on. Once we’ve encountered a new thing, our brains are able to capitalize on a … Read more

Ancient Asteroids Reveal That The Early Solar System Was More Chaotic Than We Thought

Ancient Asteroids Reveal That The Early Solar System Was More Chaotic Than We Thought

There’s no question that young solar systems are chaotic places. Cascading collisions defined our young Solar System as rocks, boulders, and planetesimals repeatedly collided. A new study based on chunks of asteroids that crashed into Earth puts a timeline to some of that chaos. Astronomers know that asteroids have remained essentially unchanged since their formation … Read more

Lava ‘Music’ Might Explain The Eruption Rhythms of The World’s Most Active Volcano

Lava ‘Music’ Might Explain The Eruption Rhythms of The World’s Most Active Volcano

The sounds of sloshing lava are music to a volcanologist’s ears. The reverberating belches and burps can help reveal what’s going on deep within a volcano’s belly. Putting an ear to the Kīlauea volcano in Hawaii has allowed researchers to track the temperature of magma and the migration of volcanic gasses as they bubble to … Read more
