1dVenus has been garnering a lot of attention lately, though primarily in the scientific community, as the last Hollywood movie about the planet was released in the 1960s. This is in part due to its dramatic difference from Earth, and what that difference might mean for the study of exoplanets. If we can better understand what happened during Venus' formation to make it the hellscape it is today, we
Could Planet 9 be a primordial black hole?
1dFor several years, astronomers and cosmologists have theorized about the existence of an additional planet with a mass 10 times greater than that of Earth, situated in the outermost regions of the solar system.
