In late December 2024 and early January 2025, a photo circulated on multiple social media sites claiming to show an ice-capped crater on Mars (archived) that scientists recently discovered.

Researchers have discovered two sets of ancient wave ripples on Mars, signatures of long-dried bodies of water preserved in ...

Eruptions of subglacial volcanoes may not be visible on the surface, but they can have consequences for the ice sheet. Heat ...

Every 26 months, the orbits of Earth and Mars allow us a closer look when Mars is at opposition — which will happen on Jan.

It’s a term used by astronomers to describe when Earth, Mars and the Sun align. When this happens, Earth sits directly ...

In addition to the newly revealed underground ocean and the abundant frost discovered on top of Mars' volcanoes, researchers ...

Mar. 13, 2024 — A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars' equator in plain sight.

The event took place during the last gasp of the Little Ice Age, one of the coldest periods on Earth in the past 10,000 years. While the year of this historic eruption was known, the volcano’s ...

Melting ice may cause dozens of volcanoes beneath Antarctica's colossal ice sheet to erupt and trigger a troubling feedback loop of environmental damage, scientists have warned. A new study by ...

More than 100 volcanoes lurk beneath the surface in Antarctica. Ice sheet melt could set them off. The reason is that this unloading of ice sheets reduces pressure on magma chambers below the ...

Some of those volcanoes peak above the surface, but others sit several kilometers beneath the Antarctic Ice Sheet. Climate change is causing the ice sheet to melt, raising global sea levels.
