Asteroid Belt

Antarctic Asteroid Crater

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.

1900 - Pauli - bio

Wolfgang Pauli was born in Vienna, Austria in 1900 and was a physicist known as one of the creators of quantum mechanics. He particularly become known for the “Pauli Exclusion Principle” which states that no two electrons can be in the same quantum state at the same time.

Asteroid Collision

It is possible (but not yet confirmed) that astronomers have observed a collision in the asteroid belt for the first time.

Water on Ceres

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. [...]

Dawn in the Belt

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.

Oort Cloud

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 [...]

Kuiper Belt

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 [...]

Small Rocks

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 [...]

Titius Bode

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.
