An exoplanet has been found in the ‘Neptunian Desert’
It's posited that this planet kept its atmosphere despite intense solar radiation pressure because it either moved into this orbit recently from a safer place, or it had much more atmosphere to begin with. I wonder if maybe it just has a very powerful magnetic field that protects it, just like Earth's does.<p>That's the reason Earth has kept its atmosphere while Mars did not, despite the fact that Mars is twice as far from the sun.
