Can life exist on Mars? The latest discovery of new evidence of liquid water on the red planet once again brings up a ray of hope.
NASA scientists said on Thursday that new evidence indicates that highly salty water may flow on Mars during its summer, which also empowers the possibility of life on the planet.
According to Dr David Leverington, of Texas Tech University, the planet's gullies were not shaped by water flows; instead they were created by low-viscosity lavas as seen in similar channel-like features on the moon and Venus, Dailymail reported.
Most experts deny Leverington's lava theory saying that the gullies were created by a volume of water, which was even greater than the largest river on Earth.
Leverington then replies back asking, "How do you get that volume of water? How do you move it quickly enough to rush out at a rate to carve channels like these?"
"He's (Leverington) reasoning on the features of the moon and Venus when we don't know the causes of those features either," Victor Baker, of the University of Arizona's Lunar and Planetary Laboratory, told Inside Science.
