Scientists Think These ‘Kidney Beans’ Could Prove That Mars Once Supported Life
Formations that look like jumbo-sized kidney beans (or blobs of chocolate syrup, depending on your palette) may be indicators ...
Scientists Say These ‘Kidney Beans’ Could Prove Life on Mars
By imaging the dunes, scientists can figure out how much CO2 frost forms on the dunes during the Martian winter. When temperatures grow warmer in the spring, the frost sublimates, transitioning from a ...

Giant 'kidney beans' spotted in Mars satellite images could point to signs of water and life
A NASA satellite has spotted frozen "kidney beans" on Mars' sand dunes trapped in place until springtime. Photographing them can help us determine if there was ever enough water on Mars to sustain ...
For children: The universe tells the story of Earth, its most special planet

NASA’s Mars Reconnaissance Orbiter captures kidney bean-shaped frozen sand dunes, offering clues to Mars' potential for life
In time, carbon dioxide ice sublimates into gas based on the tilt of the axis in Mars. As Mars' tilt changes, carbon dioxide could have turned into gas to thicken the atmosphere. Such a change in ...

Volcanic cones on Mars tell a tale of ice and fire
"Scientists think that ice moves around as the tilt of Mars' axis changes," said Dundas, "but for ice to accumulate near the equator requires much wetter conditions." A rendering of flood erosion ...
