In a new study published in the Journal of Geophysical Research: Oceans, researchers found marine ice varies in color due to the "abundance of foreign constituents in the...

Scientists see dark 'tendrils', signs of flowing water, emerge from rocky Martian outcrops Striking new images from the mountains of Mars may be the best evidence yet of flowing, liquid water, an essential ingredient for life. The findings, reported today in the journal Science, come from a joint US-Swiss study. A sequence of images from the Mars Reconnaissance Orbiter show many long, dark "tendrils" a few metres wide.
