Astronomers took images with the Pioneer Venus Orbiter in West Virginia . They combined this with the radar transmitter at the Arecibo Observatory . By comparing images , scientists hope to detect signs of active volcanism . Last week astronomers revealed a new theory for a ' Y ' shape on Venus . They say it is formed by winds pushing a 'wave ' of clouds on the planet .
