![]() ![]() ![]() Leftover debris remains in regions like the Kuiper Belt, beyond Neptune, or the Oort Cloud, beyond Pluto. Small pieces of debris stick together and grow larger over time to eventually form asteroids, planetesimals, and planets. New planets are formed by the gradual accumulation of debris, dust, and gas orbiting in a disk shape around a star. We not only want to understand how Earth’s water was delivered, but also if this process could work in other planetary systems.” “Water was crucial for the development of life as we know it. “We have identified a vast reservoir of Earth-like water in the outer reaches of the solar system,” said Darek Lis, a scientist at NASA’s Jet Propulsion Laboratory, in Pasadena, California, and lead author of the study. to collect the amount shown above from my account periodically. ![]() A comparison with information about other comets suggests that “many more comets than previously thought” could have delivered water to Earth. The collected data showed that this comet contains “ocean-like” water. The decisive factors for these findings were data from the Stratospheric Observatory for Infrared Astronomy, SOFIA, which observed Comet Wirtanen as it passed Earth in December 2018. SOFIA found clues in Comet Wirtanen’s ice grains that suggest water in comets and Earth’s oceans may share a common origin. llustration of a comet, ice grains and Earth’s oceans. According to this, the water of the oceans had its origin on comets that collided with our planet billions of years ago. Based on the results of their studies, the researchers assume that the water of Earth’s oceans and the water on many comets have the same origin. Thanks to the latest scientific findings about comets, some secrets are now being revealed as to where all the water on earth came from. Furthermore, there are lots of comets traveling through the galaxy and they consist mostly of ice and, according to the latest findings, exactly such comets may be responsible that there is water on earth – and therefore also life. For example, the polar caps on Mars and some Jupiter moons are covered by ice, and on Jupiter’s moon Europe there are even indications of oceans under the ice. However, most of the non-earthly water is frozen. No other planet in our solar system can be compared to Earth, although the oceans and lakes around the globe are not the only sources of water in the solar system. Earth is also known as the “blue planet”, since around 70% of its surface is covered by water. ![]()
