Ep 2. Mystery of Planet 9

In the second episode of the fifth season of How the Universe Works, viewers are taken on a journey to unravel the mystery surrounding Planet 9. Known as the elusive phantom planet, Planet 9 is said to lie at the edge of our solar system, lurking beyond Neptune's orbit.

The episode begins by delving into the history of how scientists came to suspect the existence of this hypothetical planet. The discovery of irregularity in the gravitational pull of celestial objects beyond Neptune's orbit prompted astrophysicists to speculate the existence of a large ninth planet, with a mass 10 times greater than that of earth.

With this premise set, viewers are then taken through a series of scientific investigations and research that have been conducted to identify this phantom planet. The show hosts featuring astrophysicists, astronomers and planetary scientists to gather as much information on their various theories on Planet 9. They examine the similarities of the planet to other planets potentially similar, what's the evolutionary history of the planet was, and what condition Planet 9 might be in currently. Scientists also present the latest findings and breakthroughs that have occurred in this field of study.

The episode emphasizes the complexity of researching something that exists purely as a hypothesis, lacking any concrete evidence. In their quest to uncover the tantalizing mystery of planet 9, scientists have been forced to look at the effects of gravitational forces, debris and other planets in the solar system.

As the show progresses, viewers are introduced to hypothetical simulations that have been developed to help astrophysicists grasp how planet 9 would be detected. They explore different scenarios that may suggest the existence of the planet. Scientists have developed simulations to help them study its effect on as to how objects are supposed to move around in the outer reaches of our solar system.

Ultimately, the show asks the question of whether we will ever truly uncover the secret surrounding the elusive phantom planet. The evidence is challenging to come by, the scientific community seems to agree that the possibility remains substantial that the Planet 9 exists, and that it plays a crucial role in the dynamics of our solar system, to say the least.

The quality of cinematography and CGI in How the Universe Works as always promises to captivate and awe its audiences. The visuals help the viewers visualize the mechanism of celestial dynamics in a most stunning and beautiful way. In summary, the Mystery of Planet 9 goes on to discuss how we human beings came to that understanding and how the mystery has always been a matter of intrigue among the scientific community.
