As part of its ongoing study of Mars’ clouds, NASA’s Curiosity rover recently captured a stunning image of a Martian sunset. As the Sun sinks over the horizon, its light forms into sun rays that can be seen banding across the sky.
Technically known as crepuscular rays, this is the first time the phenomena has been imaged in such detail on Mars. And by studying the way the rays shine through the clouds, scientists can learn more about the Martian atmosphere and weather system.
Although Mars’ atmosphere is extremely thin, at just 1 percent the density of Earth’s atmosphere, it is still active and changeable. The planet experiences high winds of up to 60 miles per hour, which can pick up the fine dust particles coating much of the planet’s…
