Mars is much like Earth in many ways and billions of years ago when the Sun was hotter, scientists speculate that Mars could possibly had water and life. One longstanding mystery, in relation to this theory concerns, the Martian atmosphere.

There are different measures of the state of an environment, such as toxins in soil or gasses in air. One measure, that can be qualified, is the microbial population since living entities directly signal the ‘health’ of a given locale.

The moon is probably 40 to 140 million years older than previously thought. This is based on new analysis of samples brought back from Apollo 14 which have been subjected to more sophisticated testing.

Early Monday morning, while people on the East Coast were making coffee, dropping kids off at school, and cursing in traffic, a space rock as big as a 10-story building slipped past Earth.
|
|
A new theory about how Earth’s moon was formed has been advanced. It speculates that several extra-terrestrial objects struck Earth creating a series of small moons or moonlets. These moonlets gradually merged to form the moon we see today.

Japanese scientists have revealed a third major element that makes up the core of the Earth, along with iron and nickel. The search for the third element has been underway for several years.
