Our research encompasses the physical and biological sciences and leverages expertise in data analytics, machine learning and advanced signal detection technologies.
This illustration depicts Keplerf, the first validated Earth-size planet to orbit a distant star in the habitable zone. Any water present on a planet orbiting here can remain liquid, given the right atmospheric pressure. Planets in the box have the right atmospheric pressure and the right temperature to keep surface water in a liquid state. In our solar system Earth and Mars are in the box, Venus and Mercury outside. The cold gas giants are literally off the chart.
The logarithmic scale used initially here allows for an easier comparison of the exoplanets.
