WASHINGTON, KOMPAS.com - and in the canyon long beach and the former is perhaps the most obvious proof of the existence of the lake on the surface Mars. According to some scientists, Wednesday (17 / 6), suspected that the lake had water, but is now dry.
Images from a camera called the High Resolution Imaging Science Experiment on board Reconnaissance Orbiter shows the water cut the canyon along the 50 kilometers. Therefore expressed the team at the University of Colorado, Boulder.
"Lake is alleged to have a size of 200 square kilometers and 450 meters depth," the researchers write in the journal Geophysical Research Letters and dilansir Reuters.
Now there is no debate that there is water in the surface of Mars; robot researchers have found ice. Also there is evidence that water may still seep to the surface from underground, despite the water immediately lost due to cold weather, the atmosphere is thin Red Planet.
Some scientists have also been on the planet to see what could be the giant river bank and the sea, but some of it can also be suspected to form and by soil erosion, dry land. "This is the first evidence that no doubts about the coastline on the surface of Mars," said Gaetano Di Achille, who led the study.
"Identifying the coastal ecology and attached to the evidence allows us calculate the size and volume of the lake, which seems to form around 3.4 million years ago," said Di Achille in a statement.
Water is the key for life scientists and explore the futile evidence about the life, both in the past, and now, on Mars. The existence of water on the planet that can also be useful for research on the human future. "On Earth, delta and the lake is a very good collector and pelestari signs of life past," said Di Achille. "If there ever life on Mars, delta may be the key to open a secret biological Mars in the past," said Di Achille.
"Not only this research proves that the lake system have a long life on Mars, but we can also see that the lake after that warm conditions, wet, alleged to have been lost," said assistant professor, Brian Hynek.
Is perhaps the lake was frozen during the vapor or climate change brief. Said the researchers. Suspected to have changed water into steam. No one knows what the planet Mars from the warm and humid as it is: frozen desert without air.
