- Scientists found the features using the Hirise imaging camera aboard Nasa's Mars Reconnaissance Orbiter
- The arachnid-like troughs are a type of land erosion where networks of cracks form in the Martian soil
- They occur at the planet’s South Pole and form when carbon dioxide turns to ice during the Martian winter
- There are thousands of them in Nasa's image according to a citizen scientist group that helped uncover them

David Bowie was right ! ' Spiders from Mars ' spotted in stunning Nasa photograph of araneiform troughs that eerily resemble the eight-legged bugs on the surface of the red planet.
It turns out the 'Spiders from Mars' are not only the name of David Bowie's
band in the well-known concept album from 1972, but are real-life
geological features etched across the surface of the red planet.
Troughs
across the surface of Mars that eerily resemble the eight-legged bugs
have been captured in a stunning Nasa satellite photograph.
Dubbed
araneiforms for their arachnid-like appearance, they are a type of land
erosion where networks of cracks form on Martian soil, completely
different to anything seen on Earth.
Scientists
from the University of Arizona located the strange features using the
Hirise (High Resolution Imaging Experiment) camera aboard Nasa's Mars
Reconnaissance Orbiter (MRO).
Volunteers
working on behalf of Planet Four – an online project hosted by
Zooniverse, the world’s largest and most popular people-powered research
platform – helped to make the discovery.
Planet
Four trawls through images of the southern polar region of Mars in an
effort to uncover formations called fans and blotches.
These could point to signs of water on the surface of the red planet, one of the main goals of the MRO.
Their
efforts assist the team behind the orbiter in directing their search to
specific locations, where they can then capture more detailed images.
'As
part of the Planet Four citizen science effort, volunteers searched
Context Camera images for possible new locations on Mars with “spiders,”
or features with radial troughs from which fans emanate in the
springtime,' a spokesman for the group said.
'We
planned this HiRISE image over one such location, to verify that they
are spiders. There are thousands of them in this image.'
