A research team from the University of Trento has found the first direct radar evidence of a lava tube on Venus, identifying ...

With Europe’s Mars Advanced Radar for Subsurface and Ionospheric Sounding (Marsis) declared a success, planetary scientists around the world are eagerly anticipating other targets for the technology.

A team of researchers has identified what appears to be a massive underground lava tube on Venus, roughly 1 kilometer wide, hidden beneath the western flank of a shield volcano called Nyx Mons. The ...

Scientists have used radar technology to shed new light on the subsurface of the moon. Researchers used the Miniature Radio Frequency (Mini-RF) instrument on NASA's Lunar Reconnaissance Orbiter (LRO) ...

ESA’s Mars Express radar sounder, MARSIS, has looked beneath the martian surface and opened up the third dimension for planetary exploration. The technique’s success is prompting scientists to think ...

The findings, reported in late March 2026, are based on subsurface imaging techniques. Archaeologists and Egyptian authorities have not confirmed the claim, prompting debate over its validity.

Two Mars orbiter missions – one from NASA, the other from the European Space Agency (ESA) – will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, ...

The European Space Agency’s (ESA) Mars Express has returned strong evidence for an ocean once covering part of Mars. Using radar, it has detected sediments reminiscent of an ocean floor within the ...
