It marks the first time for this kind of world, and could be a step towards identifying potentially habitable planets.
But until now, astronomers had never been able to take stock of what was in the atmosphere of this kind of world. To investigate, the Hubble and Spitzer space telescopes conducted a spectroscopic study of the planet, by analyzing the signatures of light that filtered through the air as it passed in front of its host star, as well as what was lost when the planet went behind the star.
The results were unexpected. The atmosphere was clear with thin hazes,………
