Earth appears to be like unimaginable when seen from house, due to its blue cowl of water our bodies. Astronomers have captured the breathtaking great thing about our planet in numerous images and movies. But has this planet all the time been like what it’s immediately? How did 70 % of Earth’s floor get coated with water? Scientists have lengthy argued the probabilities. A bunch of British scientists have now backed a long-held idea that the origin of water on Earth’s floor is extraterrestrial.

The scientists supported the concept the water on Earth is a results of comets and ice asteroids crashing down on the planet. The group’s findings are primarily based on a examine of supplies obtained from the 25143 Itokawa asteroid. This asteroid was found in 1998 and was the primary from which samples have been dropped at Earth for evaluation in 2005. The Japanese spacecraft Hayabusa landed twice on the asteroid to gather a small quantity of mud. It delivered the pattern to Earth in 2010.

According to the examine revealed within the Nature journal, scientists discovered a major quantity of water on the asteroid, elevating the potential of the presence of water within the type of ice on different planets. This additionally helped them conclude that the water on Earth’s floor may very well be due to photo voltaic winds. The group mentioned the mud particles in photo voltaic winds will need to have interacted with oxygen atoms in clouds and poured water on Earth.

Luke Daly, who was part of the analysis staff, mentioned in a statement that whereas their analysis presents exceptional insights into Earth’s previous, it may additionally assist future house missions as it could assist in discovering methods to make enough water accessible for astronauts, with out them having to hold provides. “Our research shows that the same space weathering process which created water on Itokawa likely occurred on other airless planets, meaning astronauts may be able to process fresh supplies of water straight from the dust on a planet’s surface, such as the Moon,” Daly mentioned.
