The Internet has recently been abuzz over the true color of #ThatDress, but the color of objects may pose bigger problems now that the Curiosity rover has found that Mars is actually blue and not red.
#ThatDress became an Internet sensation when Scottish singer Caitlin McNeill posted an image of a dress on Tumblr and asked people about the color of the dress: blue and black or white and gold. Netizens are in a hot debate to determine the actual color.
This, however, is not the only color-changing story of the week.
For a long time, Mars has also been referred to as the Red Planet due to the presence of iron oxide on its surface, which gives it a reddish tint.
Mars has been greatly studied in the past few decades. Scientists believe that the planet may have sustained some sort of life form thousands of years ago. Rovers are examining the Martian surface while other spacecraft are hovering above the planet to get vital information about the planet's atmosphere.
The Curiosity rover has started its drilling missions, which will collect samples that will be examined by the rover's on-board lab. The rover drilled a hole on a Martian rock called Telegraph Peak, and NASA released an image of the drill site.
The drilled soil from Mars seems to be blue or gray in color, which means that even though the surface of the planet appears to be red, under the surface it is bluish.
Scientists explain that the matter on the surface of the planet and the matter under the surface are different, hence the differences in color. Experts suggest that the red color of the planet is due to the layer of dust that covers the entire planet. The dust is believed to have been spread across the surface of the planet by ancient volcanoes. However, the matter under the surface is different.
Since the arrival of the Curiosity rover on Mars, it has been sending vital information to scientists on Earth. The mission has also been extended indefinitely, so the rover can uncover more unknown facts about Mars.
