Today, planetary scientists suspect that scorching Venus is an active, erupting world, with lava pouring down some of its volcanic slopes. The surface is clearly inhospitable for life. But why don't these researchers think this planet — a rocky world about the same size of Earth — could have once hosted inviting environs,

Venus, our closest planetary neighbor, is sometimes called Earth's twin based on their similar size and rocky composition. While its surface is baked and barren today, might Venus once also have been covered by oceans?

Our sister planet is thought to have once been a habitable world, but a new study could change that narrative and alter the search for life.

New research suggests that Venus may never have possessed liquid water oceans. That would mean "Earth's evil twin" was always hostile to life.

Astronomers have speculated for decades that Venus could once have been remarkably similar to Earth – and might have been able to support life like our own planet
