The surface is littered with vast lava plains, steep shield volcanoes, and strange pancake-like domes. This volcanic activity isn’t just a side note—it’s the main story of Venus’s surface.

Venus has several shield volcanoes that are larger (reaching hundreds of kilometers) but less steep than the volcanoes on Earth. The planet also has numerous sites with elliptical patterns ...

Sif Mons is a broad shield volcano where about 30 square kilometers (12 square miles) appear to have changed between passes; “Brighter regions observed in cycle 3 appear to completely cover some ...

Besides the towering shield volcanoes and pancake dome volcanoes on Venus, the planet also has huge canali—dried up lava channels—that show lava did flow on the planet’s surface in the ...

The slopes of Sif Mons, a large shield volcano on Venus, show signs of relatively recent lava flows (arrow) in archival data from NASA’s Magellan spacecraft, which orbited the planet in the ...

The same uncertainty has been true for Venus, until recently; while scientists previously believed that Venus’ volcanoes were inactive, new evidence is starting to push back against this notion. A ...

By using modern software to peruse Magellan’s data, scientists have now found two unambiguous lava flows: one tripping down the flank of Sif Mons, a broad shield volcano, and another winding its ...

However, the vast majority were much smaller shield volcanoes that are closer to what we find on Earth in the Auckland Volcanic Field of New Zealand or the Belknap Crater region in Central Oregon.

The newly spotted lava flows appear to have oozed out from the western slopes of Sif Mons, a huge shield volcano, and Niobe Planitia, a relatively flat region home to many volcanoes.

Evidence continues to assemble that Venus is more geologically active than previously thought. Planetary scientists scouring decades-old data from NASA's Magellan spacecraft have found signs of lava ...
