New Delhi, Mar 16 (PTI) New research has revealed a nearly 1-square-mile, or 2.6-square-kilometre (sqkm), volcanic vent on Venus that changed in shape and grew over eight months in 1991, after images taken at the time could be really processed only over the last decade.

Usually, changes on such a scale on Earth are associated with volcanic activity, whether through an eruption at the vent or through magma movement beneath the vent causing the vent walls to collapse and expand.

Venus, therefore, appears to have volcanic activity, according to the research paper, which offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.
