Watch The Red Planet (Mars) Turning Blue

Yes! You read it right! 

It might surprise you to see that while sunsets on Earth are reddish, the sunset on the Red Planet is bluish.

Curiosity rover captures the Marts’ sky as our sun sets on its horizon. The images were taken on the 15th of April on sol 956, after a three-year wait as the team worked on the Rover’s MastCam.

They were sent by the rover in black and white, but Damia Bouic the Planetary Society was able to recreate the colors to create these stunning views. By piecing together all the images taken by Opportunity, the time-lapse video of the eerie sunset was created.Watch The Red Planet (Mars) Turning Blue

According to NASA, fine dust particles in Mars’s thin atmosphere tend to make the planet’s sky look reddish normally.

But the dust also scatters blue light in the forward direction, creating a bluish sky glow near the setting sun,” NASA said in a caption for a sunset photo taken by Opportunity’s twin, the Spirit rover, in 2005.

In fact, NASA captures sunset images in part to figure out how high into the atmosphere the dust goes and to look for clouds made of dust or ice. The sun also looks very small because Mars is farther away from the sun than Earth. However, the twilight glow lasts a lot longer on Mars than it does on Earth – up to two hours after the sun sets.

That’s because of all the dust in the atmosphere scattering the light from the side of the planet that’s facing the sun.

Want to see a Mars-like sunset on Earth? NASA says it sometimes occurs after volcanic eruptions that scatter dust high into Earth’s atmosphere. And rather than turning the sky a deep orange, as happens on Earth, the setting sun gives the sky a deep blue tinge.
