Watch Origin of Water on Earth Discovered

As a science documentary, Origin of Water on Earth Discovered from is a deep dive into the origins of our planet's most precious resource: water. The film is presented by Anton Petrov, an astrophysicist and science communicator who has a passion for space, astronomy and physics. Petrov takes us on a journey through the history of the solar system and beyond, piecing together the story of how water came to exist on Earth. The film uses stunning visuals, animations, and expert interviews to explain the science behind the discovery.

The film begins with a look into the formation of the solar system. Petrov explains how the planets in our solar system were formed from a cloud of dust and gas called the solar nebula, which collapsed to form the sun at its center. Over time, the dust and gas that remained collided to form rocky bodies like asteroids, which eventually clumped together to form planets.

Petrov then goes on to discuss the formation of the Earth, which involved a process called accretion. This meant that the planet gradually grew larger over time as it accumulated more and more matter, eventually reaching the size we know today. Petrov explains that as the Earth was forming, it was subjected to intense heat and radiation, which led to the melting of its surface.

At this point, the film delves into the question of where exactly the water on Earth came from. Petrov explains that water ice was present in the solar nebula from which the solar system was formed, and that this water was trapped in the rocky bodies that eventually formed our planet. However, the intense heat that the Earth was exposed to during its formation should have vaporized all of the water on its surface.

So, how did water end up on Earth? The answer, as Petrov explains, is likely through the impact of asteroids and comets. These objects are made up of a mix of rock and ice, and they brought water to the surface of the Earth when they collided with it. Petrov discusses how the bombardment of Earth by these objects likely occurred during a period known as the Late Heavy Bombardment, which took place around 4 billion years ago.

The film then moves on to discuss how scientists have been able to gather evidence for the theory that water was brought to Earth by comets and other objects. Petrov highlights the work of the Rosetta mission, which involved a spacecraft landing on a comet and collecting data about its composition. This data was used to compare the composition of the comet's water with that of water found on Earth.

Throughout the film, Petrov is both informative and engaging, breaking down complex scientific concepts into easy-to-understand explanations. The stunning visuals and animations help to illustrate the science behind the discovery, and the expert interviews add an additional layer of insight and perspective.

Overall, Origin of Water on Earth Discovered from is an excellent science documentary for anyone interested in the history of our planet and the origins of one of its most vital resources. Petrov's passion and expertise shine through, making the film both informative and engaging from start to finish.
