Scientists are saying that in the past, Mars was a beautiful planet filled with water. Now, it is red and dusty, and the new aurora discovered is helping them to find out more about Mars. Earth has its auroras as well, situated at the pols, and they shine during the night. On Mars, instead, the aurora takes place during the day, and it is not seen with the naked eye. Let's see what NASA discovered now. Mars and Its Aurora NASA discovered Mars' aurora with the help of the spacecraft MAVEN, which is short for Mars Atmosphere and Volatile Evolution. The spacecraft is flying around the planet, and with its instrument, the Imaging UltraViolet Spectrograph (IUVS), the aurora is visible. The aurora forms thanks to the hydrogen from Mars' water. The water is slowly evaporating into space for many years by now. However, NASA scientists believe that if they could find out more information about the aurora, they can connect the missing pieces of the puzzle. More precisely, how did Mars turned into a dry and cold planet if it contained water and supposedly life on it? Andr\u00e9a Hughes, who works at the Embry-Riddle Aeronautical University in Daytona Beach, Florida, is saying that if they come to understand where all the water disappeared and is still going, maybe the mystery about life on Mars will solve. Every scientist is trying to solve this puzzle about Mars, which is practically an essential task for them. The Aurora and the Absence of Alien Life on Mars To sum up, the idea of life on Mars is not just theoretical. One of the latest studies is showing that insects and reptiles are living on the red planet. The investigation started on photographs from the surface of Mars, which shows fossils and body insects. The images are coming from NASA's rover, and Professor Emeritus William Romoser, who is an entomologist from Ohio University, is the one that is claiming the theory. If its approach is valid, then that means two things. Life does exist on Mars under the form of microorganisms, nutrients, insects, and the presence of water.
