Will humans ever be able to live on Mars? That’s the big question that a lot of people wonder about. Nicknamed the Red Planet because of its bright rust color, it is the fourth planet from the sun and Earth’s neighbor.
Despite being much colder than Earth with an average temperature of around -80 degrees Fahrenheit, there are many other obstacles in the way of humans colonizing there right now, such as the fact that there isn’t any oxygen to breathe. Scientists, however, are searching for new ways to make it possible for humans to eventually move to Mars, such as potentially heating up the planet to create an atmosphere in which people can breathe in oxygen.
Lake Vostok, Antarctica is one of the biggest subglacial lakes on Earth. The lake, which is located near the South Pole in East Antarctica, is 143 miles long, 31 miles wide, and over 2,600 feet deep. It is buried beneath more than two miles of ice and is located close to Russia’s Vostok research station. It is estimated that the lake has been covered with ice for at least 15 million years, with no access to light, and is sealed from the atmosphere which makes it one of the most extreme environments on the planet.
