Rocks that stood out as light-colored dots on the reddish-orange surface of Mars now are the latest evidence that areas of the small planet may have once supported wet oases […]
During the rover’s recent investigation of the bedrock at “Vernodden,” Perseverance encountered an unusually shaped rock about 80 centimeters across (about 31 inches) called “Phippsaksla.”
Sometimes scientists must dig and work and sweat to make scientific discoveries. And sometimes a robot rolls over a rock that turns out to be a revelation.
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere […]
Sometimes planetary physics is like being in a snowball fight. Most people, if handed an already-formed snowball, can use their experience and the feel of the ball to guess what […]
R. Graham Cooks, the Henry B. Hass Distinguished Professor of Chemistry, and his postdoctoral researcher Lingqi Qiu have experimental evidence that the key step in protein formation can occur in […]
Purdue University chemists have uncovered a mechanism for peptide-forming reactions to occur in water — something that has puzzled scientists for decades.
The accepted view of Mars is red rocks and craters as far as the eye can see. That’s much what scientists expected when they landed the rover Perseverance in the […]
Key research finding – The composition of the atmosphere, especially the abundance of greenhouse gases, influences Earth’s climate. Researchers at Purdue University, led by Stephanie Olson, assistant professor of earth, […]
