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.

Adorn Your Wrist With a 45mm Pixel Watch 3 for Just $200 This Black Friday

Both Amazon and Walmart are selling Google’s Pixel Watch 3 for just $200, but for how long?

There are tons of reasons to pick up a new smartwatch, not the least of which is monitoring your health and tracking your fitness goals. If you’re in the Android world, there are plenty of options to choose from right now. The Pixel Watch 3 is a solid choice, and it was our favorite Android smartwatch until the new Pixel Watch 4 took its place in the lineup. But the Watch 3 still boasts some great features that can help you stay on top of your wellness goals into the new year as well. And both Amazon and Walmart are running Black Friday deals that make it significantly cheaper than the Pixel Watch 4.

Both retailers are selling the bigger 45mm model with a solid $100 discount, so you can pick one up for just $200. That’s $100 less than the Pixel Watch 4’s Black Friday price. Again, this offer is available at both Walmart and Amazon, so take your pick as to where you place your order. Just do it soon because we don’t know how long these Black Friday deals will last.

The impressive watch was previously our top Android smartwatch because of its attractive design, large screen and speedy charging. It no longer requires a Fitbit Premium membership to access your readiness score, and it has plenty of great tools for runners. However, although the watch comes with Google Assistant, it doesn’t include Gemini, Google’s AI.

Lisa Eadicicco, a former senior editor, said in her CNET review, «The Pixel Watch 3’s upgrades are enough to keep it as my top pick for a general-purpose Android smartwatch. If you’re anything like me and consider yourself a casual runner in need of a general-purpose Android watch that’s sleek and comfortable, the Pixel Watch 3 won’t disappoint.»

If this isn’t the Pixel Watch for you, take a look at our full roundup on the best Pixel Watch deals going on right now.

Why this deal matters
