It is possible that one of the largest asteroid impacts in the history of the Earth has been located in Antarctica. A land mass concentration detected by satellite mapping of the gravitational field suggests a crater that is around 500 km in diameter (300 miles) and was probably created about 250 million years ago. [...]
T Pyxidis is a binary star system just over 3,000 light years from us. The two stars in the system are a sun-like star and a white dwarf star. The strong gravity of the dwarf star draws material from it’s neighbor that periodically cause it to go “nova” or explode (at least partially). [...]
Ceres is the largest asteroid in the asteroid belt and was the first asteroid ever discovered, in 1802. Recent data collected by the Hubble Space Telescope suggest that the outer mantle of Ceres is frozen liquid containing ammonia and water. There is evidence that Ceres may be as much as 20% water. [...]
Governments are organized for the purpose of common defense and the well being of the group. In a nomadic tribe, there is little to defend in the way of territory, structures or possessions, so the form of government is usually minimal and often casual. The tribe can simply pick up and move on [...]
Commerce in space will be driven by the demands of exchange and the economic factors involved.
Raw Materials:
Air and water are likely to be in high demand and even if they become somewhat abundant, will always remain treasured for their inherent importance. Food will be mostly manufactured locally, assuming you have the raw [...]
The Dawn probe spacecraft was launched from Cape Canaveral in September of 2007, used Mars as a slingshot in February of 2009 and has now reached the asteroid belt, where it will remain.

In 1950, Dutch astronomer Jan Oort (building on an idea originated by Ernst Opik) proposed that a hypothetical and massive cloud of comets that orbit far from the center of our solar system might explain why comets don’t seem to originate from deep space and often have an outer orbital edge about 20-50,000 AUs from [...]
Discovered in 1992, the Kuiper Belt is a large expanse of space just outside the edge of our solar system that contains a large number of small objects. This belt is similar to the asteroid belt, but is much larger, much farther away and may contain more frozen water and volatile gases than the metallic [...]
We know about the location of many large and medium sized asteroids, but we also know that we have not yet located all of the smaller rocks that may pose threats to life on Earth. Finding them is problematic and getting funding for the search is only the first step. The Tunguska explosion [...]
The Titius Bode law or hypothesis is a theory that planetary orbits in the Solar System are spaced in a proportional progression such that each successive orbit is roughly twice the distance from the Sun as the orbit just inside it.

The Titius-Bode Law or Rule is the observation that orbits of planets [...]
