Water on Other Planets May Be More Common Than Previously Believed

Water is thought to be one of the unique characteristics of the earth. Recently, however, this idea was proven wrong. It seems that water could be a common factor with many other planets.

Asteroids

Over 500 light-years away, a white dwarf star SDSS J1242+5226, found in the Ursa Major constellation, is leaving scientists in awe. Researchers at the University of Warwick suggest that this star has the volume of 30-35% of the earth’s water. How water arrived at this star is significant. Scientists believe a large asteroid provided the planet’s water supply. This asteroid is thought to have been about the size of Ceres in our own solar system.
