Ocean formed by Comet?

Ocean formation is still an unanswered question.

>>>Detecting Earth-like water on comets

Surrounding the surface of the earth is mostly ocean, scientists say the oceans only formed about 8 million years after the planet was born. The discovery of the ' sea-like ' component on comets by the HiFi device on the Herschel Space Observatory suggests that the ocean may have been formed by comet tape. If so, its impact has an important effect on an evolutionary phase on the earth.

Signs of seawater support the Comet hypothesis
Partial work on ocean formation.

'Without water, life will not exist on Earth and the question is always asked when and how the ocean was formed' - astronomer Professor Ted Bergin of the University of Massachusetts for know. 'It is a big question and every part of it is an important piece.'

HiFi, the probing device located at Hershel Observatory, discovered a sign of the "sea water element" above the comet Hartley 2 - the comet was explored by the ' Deep ' NASA Deep Impact However, astronomers also say that does not mean that there will be a blue ocean with fish swimming like the earth.

Maybe sea water has come to earth thanks to comets.

Comet Hartley 2 is mainly frozen ice and carbon dioxide blocks. Using the calculation method, the researchers found that Hartley's chemical composition is similar to our ocean - a blend of hydrogen atoms and deuterium, a heavy chemical isotope. . This is the first time seawater has been found in comets.

Comet Hartley 2 was explored by NASA Deep Impact.

HiFi also explored 6 other comets but did not detect which comets have the same composition. Astronomers hypothesize that Hartley 2 was formed closer to Earth than the other six comets in the Kuiper solar belt.By examining other comets, astronomers conclude that comets cannot be Earth's 'water source' . Thus, the Earth's Ocean Origin remains a topic for debate among astronomers for decades.
