The air on Venus is about 96.5% carbon dioxide, a potent greenhouse gas. All that CO2 leads to a runaway greenhouse effect ...

Venus is often called Earth's "sister planet" because of their similarities in size, mass, and composition. Both are rocky ...

Their huge size is peculiar and has forced scientists to throw out their pet theories on how planetary lava tunnels form.

New research presented at the Europlanet Science Congress 2025 in Helsinki suggests that Venus may be concealing some of the ...

Lava tubes are familiar on Earth. They form when the surface of a lava flow hardens while molten rock continues to drain ...

Scientists have presented the "first compelling evidence for the existence of lava tubes on Venus." And they're way bigger ...

Radar images of the surface of Venus appear to show fresh lava flows, suggesting active volcanoes on the planet. Scientists from Italy's International Research School of Planetary Sciences wrote in an ...

A computer-generated 3D model of Venus’ surface shows the summit of the volcano Maat Mons. Image: NASA/JPL-Caltech The surface of Venus is littered with thousands of volcanoes, some of which may still ...

Massive lava-carved tunnels have been confirmed beneath the surface of Venus, providing the strongest evidence yet that the ...

Radar images of the surface of Venus appear to show fresh lava flows, suggesting active volcanoes on the planet. Scientists from Italy's International Research School of Planetary Sciences wrote in an ...

Recent lava flows spotted on Venus suggest the planet could be much more geologically active than first thought, possibly as active as Earth. The geological processes producing these flows, first ...
