A team of astronomers from the Massachusetts Institute of Technology (MIT) say they have discovered a distant planet that they can’t explain with current planet evolutionary theories.
The newly discovered WASP-193b is a gas giant 50 percent larger than Jupiter, the largest gas giant in our solar system. However, it is only one-tenth as dense, making it the second-most dense exoplanet ever found.
The researchers behind the seemingly impossible find, which also includes experts from Belgium and Spain, say these types of “puffy Jupiters” have left astronomers baffled for over 15 years since they cannot explain how they formed using the best modern-day planet forecasting tools
“We don’t know where to put this planet in all the formation theories we have right now because it’s an outlier of all of them,” explained study co-lead author Francisco Pozuelos, a senior researcher at the Institute of Astrophysics of Andalucia, in Spain. “We cannot explain how this planet was formed based on classical evolution models.”
