Could Europa be habitable?
Europa has many cracks in its otherwise smooth surface. Many believe the cracks are the result of the rising and falling of tides in a global ocean beneath Europa’s icy surface. A new study adds to the evidence that this subsurface ocean may be habitable.
How could we live on Europa?
Europa, the fourth-largest moon of Jupiter, is a subject in both science fiction and scientific speculation for future human colonization. Europa’s geophysical features, including a possible subglacial water ocean, make it a possibility that human life could be sustained on or beneath the surface.
Is the moon livable?
In the Solar System’s habitable zone, there are only three natural satellites—the Moon, and Mars’s moons Phobos and Deimos (although some estimates show Mars and its moons to be slightly outside the habitable zone) —none of which sustain an atmosphere or water in liquid form.
What is the average temperature on Europa?
Temperature: Europa’s surface temperature at the equator never rises above minus 260 degrees Fahrenheit (minus 160 degrees Celsius). At the poles of the moon, the temperature never rises above minus 370 F (minus 220 C).
Is there oxygen on Europa?
Europa has only a tenuous atmosphere of oxygen, but in 2013, NASA announced that researchers using the Hubble Space Telescope found evidence that Europa might be actively venting water into space. This would mean the moon is geologically active in the present day.
How thick is the ice on Europa?
around 15 to 25 kilometers
Theory and observation indicate that Europa’s icy shell is around 15 to 25 kilometers (10 to 15 miles) thick, overlying an ocean approximately 60-150 kilometers (40 to 100 miles) deep. Support for this hypothesis comes from observations of pits, domes, and spots on Europa’s surface.
Which country in Europe has the highest population density?
1. Monaco. Monaco is a small city-state with the highest density in the Europe and one of the most densely populated in the world. Monaco has an area of 0.78 square miles, a population of about 38,400 and the population density of more than 40,000 people per square mile.
What is the smallest population in Europe?
Vatican City – 0.44 sq km. The state of Vatican City is the smallest country in Europe and as well as in the world both by size and population with an area of around 0.17 square miles. The country is not formally self-governing, and it is governed by the Holy See. The population was estimated at 1,000 in 2015.
What is the largest country in Europe by population?
Russia is the world’s largest country with an area of 6,592,800 square miles and the second less densely populated country in Europe. Russia is also the most populous European country with a population of more than 144 million people.
