UK Seas See Record-Breaking Warmth, New Species Arrive
Sea temperatures around the UK have reached record highs, with BBC analysis revealing that the average temperature from January through July 2025 was over 0.2°C warmer than any year on record since 1980. The unusually warm conditions have attracted unexpected marine life, including bluefin tuna and salps—bioluminescent, jelly-like creatures rarely seen in British waters.
A Visitor from the Stars: Comet 3I/Atlas Caught on Camera
Astronomers using NASA’s Hubble Space Telescope have captured the clearest image yet of 3I/Atlas, a comet speeding through our Solar System from beyond the Milky Way. It’s only the third known interstellar object ever observed near Earth. The comet is estimated to be travelling at over 209,000 km/h (130,000 mph)—a record-breaking pace.
“It’s like seeing a bullet fly by in a blink,” said David Jewitt, a leading astronomer at UCLA and part of the Hubble research team.
Fuzzy Caterpillar Invasions Explained
In British Columbia, Canada, a peculiar natural cycle sees Western tent caterpillars swarm every ten years—only to mysteriously disappear again. After 50 years of research, zoologist Judith Myers has discovered that a virus unique to these insects drives this cycle. Her latest study also finds that the species appears highly resilient to climate change.
Wildfires Rage Across Southern Europe Amid Heat Alerts
Scorching heatwaves have ignited multiple wildfires throughout southern Europe, prompting evacuations across Spain, Portugal, France, and Italy. Red heat warnings were issued as temperatures soared past 40°C (104°F). Experts link the increasingly intense fire seasons to climate change, with Europe’s temperatures rising at double the global average since the 1980s.
The Night Sky Lights Up: Perseid Meteor Shower Peaks
Skywatchers across the Northern Hemisphere were treated to a spectacular display as the Perseid meteor shower lit up the night earlier this week. The shower is caused by debris from the comet Swift-Tuttle, which orbits the Sun every 133 years. As Earth passes through the comet’s dust trail, particles burn up in the atmosphere, creating the dazzling streaks seen across the sky.
