ESA’s Mars Express Discovers Deep Valleys and Frozen Features Hinting at Mars’ Icy Past
In July 2025, the European Space Agency’s Mars Express orbiter captured a high-resolution image of Acheron Fossae, a region marked by deep chasms and ridges on Mars’s surface. These features, created by ancient crustal stretching, split the terrain into raised horsts and sunken grabens. Valley floors reveal smooth surfaces carved by slow-moving...

Earth's Orbit and Tilt Linked to Ice Age Cycles, Next One Delayed by Climate Change
Scientists have discovered a strong link between Earth's tilt and past ice ages, predicting the next glacial period would have started in 11,000 years. However, rising greenhouse gas emissions are disrupting these natural cycles. The research, based on ocean sediment data, supports the theory that Earth's obliquity governs ice expansion while prece...

Ancient Ice Core from Antarctica May Reveal Climate Mysteries from 1.2 Million Years Ago
A team of scientists in Antarctica has extracted a 2.8-kilometre-long ice core from Little Dome C, believed to be 1.2 million years old. The ice core contains trapped air bubbles and volcanic ash, offering valuable data on climate shifts and the Mid-Pleistocene Transition. The research aims to uncover the cause behind significant climatic changes a...

Radar Images Reveal Mars Is Coming Out Of An Ice Age
An analysis of radar images that peered inside the polar ice caps of Mars shows that Earth's neighbor is coming out of an ice age that is part of an ongoing cycle of climate change, scientists said on Thursday.

Global Warming Could Stave Off Next Ice Age For 100,000 Years
Global warming is likely to disrupt a natural cycle of ice ages and contribute to delaying the onset of the next big freeze until about 100,000 years from now, scientists said on Wednesday.

Ocean Currents Behind Change in Ice Ages?
Climatologists have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles.
