Saturn’s ice-covered moon Enceladus could harbor a warm-water ocean beneath its frozen surface, opening up new possibilities for life beyond Earth. Enceladus has fascinated astronomers since 2005, when NASA’s Cassini probe caught geysers on the moon’s south pole spewing out plumes of salty water. Water that is thought to have originated in an ocean buried beneath the moon’s 25-mile-thick ice […]

Scientists have revealed that some fish that thrive in the freezing cold waters of the Antarctic actually have ice in their veins. A protein in their system called notothenioids not only keep the fish from freezing to death, but also keeps ice crystals in their veins. Although the ice crystals would melt at temperatures just slightly above freezing, the fish […]

The planet’s inexorable warming means there will be no new ice age for at least the next 100,000 years, scientists say. Human beings have not just started to leave a unique geological stratum that will announce their existence long after the species has been extinguished. They may have altered a climate cycle that has been stable for millions of years and even […]

There’s no question that our species has had a dramatic impact on the planet’s physical environment, particularly over the last few centuries, with the rise of modern industry, transportation, and infrastructure. But as new research shows, humans have been transforming the landscape, with lasting impacts, since long before the start of the Industrial Era. Scientists from MIT and the University […]

Polar bear numbers are expanding The Effects of Global Warming on Polar Bears has been quite significant. “A main Canadian power on polar bears, Mitch Taylor, said: ‘We’re seeing an increment in bears that is truly phenomenal, and in spots where we’re seeing an abatement in the populace it’s from chasing, not from environmental change.’” (Scotsman.com) Polar bears are found […]

For the first time, scientists have caught a glimpse of a black hole ejecting a hot “flare” of matter after devouring a star the size of our sun. The discovery was made thanks to the quick action of of scientists from John Hopkins University, who worked in conjunction with a team from the University of Oxford. Hubble fellow Sjoert van […]

As the planet faces the dawn of a sixth mass extinction, scientists are searching for clues about the uncertain road ahead by exploring how an ancient ecosystem collapsed and bounced back from traumatic upheavals. A new study follows the lengthy collapses and revival of South African ecosystems during one of the “big five” mass extinctions, the Permian-Triassic event, revealing unexpected […]

In 2016, a Canadian novelist, Craig Russell — who is also a lawyer and a theater director in Manitoba — wrote an environmental cli-fi thriller titled “Fragment” about a major calving event along the ice shelf of Antarctica. The Yale Climate Connections website recently recommended the novel, published by Thistledown Press as a good summer read. Ironically, scientists in Antarctica are […]

Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS). This map of […]

When the atmosphere had much higher levels of carbon dioxide, Antarctica was as warm as California. New research has revealed that 430 million to 50 million years ago, temperatures on the frozen continent averaged 57 degrees Fahrenheit, with part of the surrounding Pacific Ocean reaching up to 72 degrees. In this ancient era, known as the Eocene epoch, carbon dioxide […]
