In 1996, Columbia scientists shifted Biosphere 2’s 2.6-million-gallon Arizona ocean between ice age, modern and future CO₂ every 3 months; future chemistry cut coral calcification by about 40%
The same scientists who reported water erupting from Europa in 2014 have now reanalysed 14 years of Hubble data and cut their confidence from 99.9% to below 90%. The signal may have been statistical noise, leaving Europa’s famous geysers physically plausible—but never conclusively observed, and never proven to connect with the ocean below.
Scientists looked inside a rock pellet smaller than a grain of rice and found a 445-million-year-old world preserved within it — more than 20 microscopic marine organisms, including a species never seen before
In 2011, scientists injected yellow-green fluorescein dye into Maui’s wastewater wells; 84 days later, it appeared near the Pacific, supporting an underground wastewater connection
Scientists documented 1,121 previously unknown marine species in a single year — increasing the annual identification rate by 54 percent — yet the head of science at Ocean Census says researchers are still in a race against time, with estimates suggesting up to 90 percent of ocean species remain undiscovered.
Scientists thought Titan was hiding a global ocean beneath its frozen crust. But a 2025 reanalysis of Cassini data points to something stranger instead — a roughly 380-kilometre-thick layer of slushy ice, close to melting and likely threaded with pockets of liquid water that could reach 20°C near the rocky interior.
