Astronomers detect first exomoon. Astronomers confirmed a moon orbiting a planet outside our solar system for the first time, 73 light-years from Earth — a discovery blurring the lines between stars, planets, and moons.

The detection, reported by Wired, challenges existing definitions of celestial bodies because of the object's unusual characteristics. Scientists say the find raises new questions about how moons form around planets in distant star systems and whether such objects are common across the galaxy. The discovery is considered a milestone in exoplanet research.

UN chief warns on strengthening El Niño. UN Secretary-General Antonio Guterres warned a strengthening El Niño could shatter all-time records, compounding a record-hot summer across the U.S. and Europe and pushing the world into 'uncharted territory.'

Guterres made the warning as El Niño, the periodic Pacific Ocean warming pattern, was intensifying. According to Phys.org, the combination of human-caused climate change and El Niño's natural warming effect was already driving record temperatures across the U.S. and Europe. Scientists have said El Niño cycles typically peak months after onset, meaning further temperature records could follow.

'Ghost lineage' DNA may live in everyone. Scientists analyzing modern genomes may have identified a previously unknown group of ancient humans — a long-lost branch of the family tree — whose DNA survives in every living person today.

According to Scientific American, the finding emerged from analysis of DNA in modern human genomes rather than from fossil evidence. The so-called ghost lineage left no known physical remains, making genomic analysis the only available window into its existence. Researchers say the discovery suggests human prehistory involved more interbreeding among distinct populations than previously understood.

Google pulls Earth AI tool after one day. Google shut down a Google Earth feature that generated AI imagery over real satellite maps within 24 hours of launch, after users created deepfakes depicting fake disasters and conflict damage.

According to TechCrunch, the feature allowed users to overlay AI-generated imagery onto real satellite maps, and within hours of launch people were using it to fabricate scenes of destruction, floods, and conflict damage in identifiable real-world locations. Google did not immediately say whether the tool would be revised and relaunched or discontinued permanently.
