No one will doubt that China aims to win the new space race. Not only is it the only country to have landed on the moon in over 40 years, but it is also the first to make a soft landing on the far side of the moon, plant a flag on the lunar soil and even bring lunar soil samples to Earth. It is now also landing a robotic all-terrain vehicle on Mars

The Sophia airborne observatory has detected water molecules (H2O) in Calveus Crater, one of the largest craters visible from Earth, located in the southern hemisphere of the Moon. Previous observations of the lunar surface detected some type of hydrogen compound, but failed to distinguish water from its close chemical relative, hydroxyl (OH)

Harvard University scientists say the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed and the ninth planet was trapped rather than formed within the solar system.
