The OSIRIS-REx spacecraft arrived at the asteroid Bennu on December 3rd. This mission will return samples from this body to the Earth for study by researchers. Bennu was discovered in 1999, and this carbon-rich asteroid is believed to be older than the solar system. Researchers hope the mission will help teach us more about the ancient solar system and the formation of life on Earth. The sample material is scheduled to land in the desert of Utah in the year 2023. This is the first U.S. mission to land on an asteroid.Read More OSIRIS-REx Arrives at the Asteroid Bennu – Tucson and the World Celebrates
An asteroid orbiting backwards around the Sun may have come from another solar system, according to astronomers in France.
Asteroid 2015 BZ509 is roughly two miles across, and orbits the Sun at roughly the same distance as Jupiter. Computer simulations suggest the object may have joined our planetary family four-and-a-half billion years ago, just as the Earth and other planets were being formed.
The two tiny moons of Mars have puzzled astronomers for decades. New research now suggests they may have been created in a giant impact. billions of years ago, when Mars collided with a rocky body 500 miles in diameter.Read More The Moons of Mars May Have Been Born in Giant Impact
