Astronomers Report Increased Possibility of Life on Distant K2-18b Planet

With the help of the James Webb Space Telescope, astronomers say they’re closer than ever to confirming signs of life on a distant exoplanet.

A team of astronomers led by the University of Cambridge say they’re closer to a statistically significant scientific finding that would show that signs of life they’re detecting from the distant exoplanet dubbed «K2-18b» are no accident.

The astronomers used data from the James Webb Space Telescope, which has only been in use since the end of 2021, to detect chemical traces of dimethyl sulfide and/or dimethyl disulfide, which they say can only be produced by life such as phytoplankton in the sea. According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»

The findings were published this week in The Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years.

In the abstract for the research paper, the team says: «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»

K2-18b is 124 light-years away and and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases that chances that their are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms.

The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.

Rideable Horse Robot Viral Video: The Real Story Behind It

Kawasaki’s Corleo robot horse is just a concept right now, but a thrilling hype video makes it look like a blast to ride.

If you’ve ever watched a video featuring a Boston Dynamics Spot robot dog and wanted to saddle it up and ride it, then Kawasaki has a concept robot that’ll make your heart flutter — and it’s part horse, part leopard, part robot and all wild. Too bad you can’t actually buy one.

The Kawasaki Corleo is a four-legged rideable robot, the answer to the question: «What if we put legs on an all-terrain vehicle instead of wheels?» Kawasaki released a video showing what the concept would look like if it were fully realized.

The trippy video features the Corleo and riders galloping through a forest, running across a field, leaping over rocky terrain and trotting across a snowy landscape. The video appears to be primarily computer generated with Lord of the Rings-worthy scenery.

Kawasaki is known for its motorcycles and ATVs, but the international company has its hands in everything from railcars to industrial equipment and robotics.

Kawasaki unveiled the forward-thinking Corleo for the Osaka Expo 2025 in Japan. It’s a 2050 concept model for a future mode of transportation. The expo’s theme is «designing future society for our lives.» The event officially opens on April 13.

Corleo incorporates some nifty design ideas, including independent legs, a hydrogen engine and steering through weight shifting.

«While preserving the joy of riding, the vehicle continually monitors the rider’s movements to achieve a reassuring sense of unity between human and machine,» Kawasaki said.

Kawasaki didn’t immediately respond to a request for comment on its plans for Corleo.

For now, Corleo is just a model capable of limited movement, so your sci-fi dreams of riding across rugged mountains on a kick-butt robo-steed will have to be put on hold. Perhaps 2050 will bring us a world full of leggy, rideable robots. Somehow, that feels more achievable than a bunch of flying cars.
