Venus has long been written off as a 'dead' planet - but astronomers have revealed if it showing signs of change.
A new global view of some well-known features on Venus's surface may indicate its crust is moving.
Experts - Movement - Mountain - Ridges - Process
Experts say the movement of mountain ridges is extremely similar to the same process happening on Earth.
Researchers used radar images of Venus's surface from the Magellan mission between 1990 and 1994 to view the structures on the surface from a global perspective.
Pattern - Mountain - Ridges - Grabens - Blocks
This revealed a new pattern - these mountain ridges and grabens converge to isolate blocks of flat, low-lying plains of cooled lava along the planet's poles, something never noticed before.
Scattered on Venus's surface are various narrow mountain ridges and surface grooves, or grabens, which scientists have known about for decades, but had only viewed them in isolation from one another previously.
Features - Pattern - Paul - Byrne - Findings
'When you zoom out, you see that these features form a connected pattern,' said Paul Byrne, who revealed the findings at the 2017 American Geophysical Union Fall Meeting in New Orleans.
'That's when you realize that they seem to be working together.'
Researchers - Structures - Lot - Features - Earth
The researchers say the structures looked a lot like features seen on Earth, such as the Tarim Basin in northwestern China.
These are large pieces of continental crust that jostle, rotate and crash into surrounding...
