The thin, dark streaks on the slopes of Bamai hills like the one in the section of the Horowitz Crater could have been formed by the seasonal flow of water on present-day Mars. The channels are several hundred meters long

Scientists from Stanford: discovery of flowing water on Mars increases the chances of life on the planet

The light is deflected out of the surface of the cloak (red arrows) as it would be deflected by a flat mirror. [Courtesy: Xiang Zhang group, Berkeley Lab/UC Berkeley]

The dark narrow channel known as recurring slope lineae flows down a hill on Mars photographed in infrared light and appears to be an area where water flows today. Recently, scientists located brackish water on this hill located in the Hale Crater, thus confirming an original hypothesis that the channel was indeed formed by flowing water. The blue color upstream does not seem to belong to this configuration but rather they are formed in the presence of the mineral peroxin. Credits: NASA/JPL/University of Arizona

The color and brightness of the moon can change sharply from one eclipse to the next, depending on the amount of volcanic ash in the atmosphere. The dungeon scale, which rates the lunar eclipses from zero to four, will help you viewers gauge the appearance of the moon during the eclipse tonight. Credit / Photo illustration: Bob King

A simple experiment: watch the total white eclipse tonight, compare it to the scale in the article and report the color of the moon to the scientist who studies the atmosphere of the Earth
