Israeli-born scientist says study is the first step in determining whether there is life on planets beyond our solar system.
The traditional approach to this hypothetical scenario is to deflect the orbit of the incoming threat, but a scientist recently proposed an innovative approach.
"Compared to the most recent Ice Age, glacier coverage was much more extensive and, more importantly, much of the ocean was frozen," Xiao said.
The researchers discovered this by looking at the excess ultraviolet radiation, which is seen as a line of hydrogen in Saturn’s atmosphere.
Scientists recommend finding a clear view of the western horizon and using binoculars to view the planets.
Exoplanet VHS 1256 b is a gas giant 40 light years away from Earth that orbits a binary star system. Its constant shifts in brightness with its clouds make it the most volatile world ever seen.
The water probably would have originated from volcanic activity and gradually evaporated into the atmosphere, along with other vital compounds.
Tidally locked worlds have one side always day and another always night. Life should be impossible here, but a strip in the middle could support life.
“Despite many astronomers having wished for this extra planet, it’s a good thing we don’t have it,” said lead author Stephen Kane.
The existence of the exoplanet gas giant TOI-5205b around a small red dwarf star should be completely impossible, challenging previously-held theories.
