There are many mysteries concerning the universe: what blackholes even are, how many dimensions exist, how a galaxy can actually shoot itself across space and time, and why humanity hasn’t yet started its moon colony.
But there was one thing we all knew — Mars is really red. If everyone settled on the red planet tomorrow, we could look forward to red canyons, red mountains, red sunsets and everything else coloured in rust.
Except that’s wrong, too. NASA’s Curiosity Mars rover captured a very blue sunset, contrasting to Earth’s orange and red sunsets. Mars is somewhat red — during the day, the sunlight scatters light through dust particles to make the planet seem more orange.
Mark Lemmon of Texas A&M University shared with Nasa, “When the blue light scatters off the dust, it stays closer to the direction of the sun than light of other colors does. The rest of the sky is yellow to orange, as yellow and red light scatter all over the sky instead of being absorbed or staying close to the sun.”
Ongoing photos from Curiosity’s Mastcam (Mast Camera) has continuously proven a day on Mars is incredibly similar to a day on Earth. Since its landing in the Gale Crater on August 2012, Curiosity has been revealing more and more mysteries Mars has been keeping hid away this entire time.
The mission with Curiosity is still ongoing. NASA has been using Curiosity to find signs of life on ancient Mars, details on the atmosphere and mapping the planet’s surface. To follow the adventures of Curiosity, NASA has set up a facebook page.
