A Super Earth with liquid water has been discovered by NASA and may be habitable for some kind of life meaning we may not be alone in the universe.
Planet K2-18b is a super-Earth that orbits its sun in the Leo constellation. The planet is approximately 110 light years away and is the first discovery of water on another planet that could support alien life.
Scientists at the University College London (UCL) have found that the super-Earth contains liquid water and even has an atmosphere.
Water was detected in the planet’s atmosphere by measuring light waves filtering through hydrogen molecules.
The discovery was made from archived data in NASA’s Hubble Telescope from 2016 and 2017. Though Hubble didn’t have the capabilities to spot any signs of life, new telescopes will be launching soon that will be able to search for biosignatures and aim to answer the biggest question in philosophy and science… ‘Are we alone in the universe?’
The Super Earth could well harbor life and has conditions for such, but biological humans would have two difficulties living there. Due to the planet’s gravitational forces being too strong it would be impossible to walk on the planet and the immense sunlight would likely make any human develop cancer.
Some websites claim that the planet is not habitable at all, but they’re limiting their calculations to human life or similar. Something many overlook is that alien life is something we’re not able to explain yet, because it is alien to us. The conditions that we require may not be the conditions another biological race may require.
The conditions on the planet may be totally suitable for some form of biological beings that have adjusted to the planet’s gravity and might even have large amounts of melatonin in their skin to protect them from the UV rays. They would likely have completely different biological structures altogether.
Maybe they have something similar to the fungus that was found to eat radiation.
Dr Angelos Tsiaras, of UCL’s Centre for Space Exochemistry Data, said: “Finding water in a potentially habitable world other than Earth is incredibly exciting.”
