Astronomers Say There’s an Increased Possibility of Life on This Distant Planet

Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.

The team of astronomers, led by the University of Cambridge, 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 (DMS) and/or dimethyl disulfide (DMDS), 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 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.»

Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.

Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»

K2-18b is 124 light-years away 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 the chances that there 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.

More research to do on finding life on K2-18b

The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.

«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»

Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»

The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»

As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.

«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»

Formula 1 Fans Can Now Explore Race Circuits With Apple’s New Maps Guide

F1 fans can get revved up for the approaching season with a tech boost from Apple Maps.

If you’re a Formula 1 fan and have your iPhone handy, you might want to check out Apple Maps. Apple on Wednesday added a new guide for its Maps app showcasing the race tracks for next month’s Australian Grand Prix.

Users can explore a detailed, 3D version of Melbourne’s Albert Park Grand Prix Circuit directly in Apple Maps and find details for all 24 tracks of the season with the Formula 1 Tracks From Around The World guide. It can also be found on the Apple TV Formula 1 Channel.

Currently, the only location done up in 3D is the Albert Park map, where you can explore the F1 Pit Garage, stadiums and more. Apple will continue to add more 3D tracks throughout the year.

The updated maps include:

Grand Prix Elements: Kerbs are shown on the maps to match the real-life experience, along with grandstands and pedestrian footbridges, all in 3D and labeled. All 14 of the circuit’s turns are also labeled.
Pop-Up Locations: Attendees will easily find entrance gates, restrooms, water stations, first aid and merchandise stands. Walking paths are shown directly on the maps, with walking directions available for grandstands.
3D Grand Prix Circuit Landmarks: The Pit Building, Lakeside Stadium (Bob Jane Stadium), Melbourne Sports & Aquatic Center, and the Finish Line are all prominently highlighted and showcased.
3D Melbourne Landmarks: Attendees looking to explore further can find several of Melbourne’s landmarks detailed in 3D in Maps.

Last year, Apple paid $140 million for exclusive F1 streaming rights in the US.

Instagram Will Alert Parents if Teens Repeatedly Search for Self-Harm and Suicide Terms

The change applies to accounts using parental supervision tools.

Instagram will soon alert some parents if their teen repeatedly tries to search for terms related to suicide or self-harm within a short period. Instagram owner Meta said on Thursday that it’s rolling out the new notifications to parents in the US, UK, Australia and Canada, with other regions to follow later this year.

Thursday’s update follows the 2024 introduction of teen accounts. It applies to parents using the platform’s optional parental supervision setting, which requires consent from both teens and their parents to participate. Parental supervision allows parents to see the accounts their teen follows, set a time limit for how long their teen can use the app and more.

If teens repeatedly make suicide-related searches, parents will receive alerts via in-app notifications and email, text or WhatsApp, depending on available contact information. In addition to informing parents of their teen’s searches, notifications will allow them to «view expert resources designed to help them approach potentially sensitive conversations with their teen,» according to Meta.

Meta said it would prompt an alert if a teen attempted to search for phrases promoting suicide or self-harm and phrases that suggest a teen wants to harm themselves. The company said its policy is to block searches for self-harm and suicide content and direct people to resources and helplines.
