A recent study from the University of Cambridge has revealed the existence of a planet, 70 light years away from our solar system, that may be covered entirely by water. However, unlike our familiar Earth oceans, this planet’s ocean might be as hot as a boiling pot of water.
Using data collected by NASA’s James Webb Space Telescope, astronomers focused on the TOI-270 system, specifically studying a planet called TOI-270 d. Initially thought to have a gaseous composition similar to Neptune, further analysis suggests that this planet might actually be a “Hycean world” with a large ocean and a hydrogen-rich atmosphere.
What is truly remarkable about this discovery is the calculated temperature of TOI-270 d, which could reach up to 212 degrees Fahrenheit, the boiling point of water. However, differing opinions among scientists make the interpretation of the data a subject of debate. While some believe that the planet is indeed covered by a hot ocean, others propose an alternative theory: that the planet has a rocky surface and an atmosphere composed of super hot steam and hydrogen.
University of Montreal astrophysics professor, Björn Benneke, argues that the temperature is too high for water to exist in a liquid state. Despite the ongoing discussion, the ability to detect the chemical signatures of distant exoplanets is a significant accomplishment. Since the first exoplanet detection in 1992, the number of known exoplanets has grown exponentially.
This discovery opens up a fascinating avenue of exploration as scientists continue to search for planets beyond our solar system. The ultimate question remains: Will we ever find a planet as hospitable as our own in this vast array of exoplanets? Only time and further research will provide the answer.
