Scientists Say Climate Change Is Making Earth's Days Longer Than Before
Scientists said the current rate of day lengthening is around 1.33 milliseconds per century.

Why Polar Bears Approach Human Infrastructure? It's All About Ice
Findings suggest that sea ice loss probably doesn't lead to more interactions with people just because polar bears are thinner or hungrier.

The City That Does Not See The Sun For 4 Months
Svalbard's Longyearbyen experiences a Polar Night from mid-November to late January with total darkness for about 75 days.

Record-Breaking Drill Beneath Antarctic Ice Reveals Ancient Open Ocean and Future Sea Level Risks
Scientists drilled deeper than ever beneath the West Antarctic Ice Sheet and found sediment and marine remains showing the area was once open ocean. The 23-million-year record offers key clues about past melting, helping researchers better predict how quickly the ice sheet could retreat and affect future global sea levels.

Scientists Reveal Why Jupiter and Saturn’s Polar Weather Looks So Different
Although Jupiter and Saturn are similar gas giants, their polar weather patterns are strikingly different. Saturn hosts a single, massive hexagonal storm at its north pole, while Jupiter features a central cyclone surrounded by smaller vortices. New simulations suggest the contrast may arise from differences deep inside the planets. A denser, “ha...

NASA Spots Giant Antarctic Iceberg Turning Blue as It Nears Breakup
NASA scientists are closely tracking iceberg A-23A as vivid blue meltwater pools spread across its surface, signalling rapid decay. Once covering nearly 4,000 square kilometres, the Antarctic megaberg has shrunk to about 1,180 square kilometres and is fragmenting in warmer South Atlantic waters, offering valuable insight into how rising temperature...

NASA's IXPE Solves Long-Standing Mystery Behind Black Hole Jets
NASA's IXPE mission has identified how X-rays are produced in the jet of a supermassive black hole, confirming that they originate from the same jet through synchrotron self-Compton scattering and resolving a long-standing question in X-ray astronomy

Ariane 6 Launches Metop-SGA1 Weather Satellite into Polar Orbit
Europe’s heavy-lift Ariane 6 rocket completed its third successful launch on Aug. 12, 2025, lifting off from Kourou, French Guiana at 8:37 p.m. EDT. The mission carried Metop-SGA1, an 8,900-pound next-generation polar-orbiting weather satellite operated by EUMETSAT. Placed into an 800 km polar orbit 64 minutes after liftoff, Metop-SGA1 will deliv...

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...
