To understand the discrepancy, the researchers considered a scenario around four billion years ago when a star-sized alien object, whizzed around in our solar system. They ran extensive ...

To test their theory, a team of researchers at NASA used satellite data and computer models to create an Earth-like model covered with silicon solar panels with varying ranges of coverage.
