By Will Dunham WASHINGTON, Feb 9 (Reuters) - A fresh examination of radar data for Venus obtained by NASA's Magellan spacecraft in the 1990s indicates the presence of a large underground cavity ...

On Mars or the Moon, researchers use high-resolution optical cameras to spot “skylights,” which are essentially holes in the ground where a cave roof has collapsed. But on Venus, the thick atmosphere ...

Volcanic activity is not unique to Earth: traces of volcanic activity, such as lava tubes, have been found on Mars and the moon. Now, the University of Trento has demonstrated the existence of an ...

Venus has long been cast as the solar system’s hellscape, a world of crushing pressure and searing heat where spacecraft survive for minutes, not days. Now a new line of research suggests that beneath ...

The combustible sedimentary rock, better known as coal, was not only crucial to the onset of advanced technology here on Earth, but it should also be key to the development of advanced E.T.s residing ...

A major study by an international team of researchers using data from the NASA/ESA/ASI Cassini spacecraft has revealed a lattice-like structure of crisscrossing reflected waves that flow downstream ...

A massive subsurface structure has been discovered on Venus, according to astronomers relying on radar data analysis.

Using archival radar data from NASA’s Magellan spacecraft, planetary researchers have identified a vast underground conduit beneath the surface in the Venusian region of Nyx Mons.
