![]() Many glacial landforms from the last time this occurred can still be seen on Mars. During periods of higher obliquity, the atmosphere is thicker, dust storms are more intense, and water now trapped at the poles moves to the equatorial region to form mountain glaciers. As a result, the tug of gravity from the Sun and the large planets causes a slow wobble in the tilt, or obliquity, of its axis. Mars has no large satellite like the Moon, just its two small moons Phobos and Deimos. Like Earth, Mars spins on an axis tilted about 25 degrees from its orbital plane. “The thinner atmosphere is the big game changer,” he said. While we experience temperature drops like that here on Earth-Shindell compared it to how hot desert climates cool substantially after sundown-it happens on a much different scale on Mars. The sand and rocks of Mars’ surface lose their heat quickly. ![]() ![]() Temperatures also dip drastically from day to night because there is little to retain heat on the planet. There might be a 15-20 degree temperature change between where your feet are and where your head is if you were standing on Mars,” Matthew Shindell, curator of planetary science and exploration, said. “The temperature on Mars right near the surface, in the path of the Sun, is going to be a lot warmer than if you were to raise even five feet up. Because it has about a sixth of the pressure of Earth’s atmosphere, the planet doesn’t retain heat very long, causing temperatures to drop quickly. Overall, Mars is cold-its average global temperature is around -80 degrees Fahrenheit-and has a much thinner atmosphere than Earth. But how does Mars’ climate compare to that of our home planet? Those are temperatures so frigid that parts of Mars-a cold, desert planet-are actually warmer than certain spots in the U.S. “There are many examples of this phenomenon on Earth and in space.The northeastern United States is experiencing record-breaking cold weather, with temperatures 20 to 30 degrees below average, according to the National Weather Service. “Pareidolia is the psychological phenomenon where people see recognizable shapes in clouds, rock formations, or otherwise unrelated objects or data,” the agency said in a statement. This is the same concept used to explain most UFO and paranormal sightings. According to NASA, this is a psychological phenomenon that causes people to see certain things in various objects. “Ice melting could be revealing structures that would baffle the world.”Īlthough the image strongly resembles an alien face, this could be simply attributed to pareidolia. ![]() ![]() “Could this be something that was left behind by the ancient civilizations of Antarctica?” they added. “I would have to concur that whatever we’re looking at resembles some sort of megastructure.” “It appears to be a massive, ancient structure of some kind of face that is being revealed for the first time on Google Earth,” they said in a video. They noted that it remained undiscovered for a long time because it was buried underneath the snow. According to the YouTube channel thirdphaseofmoon, the image of the alien face was first discovered by an Italian researcher named Matteo Ianneo, who posted the Google Earth coordinates of the strange sighting on his blog.īrett and Blake cousins, the operators of thirdphaseofmoon, speculated that the alien face might actually be a large structure that was built by an ancient race of aliens that visited Antarctica. ![]()
