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
Dinosaurs were wiped out by an asteroid impact 66 million years ago. But, new research suggests plankton and other animals returned to the impact site just a few years after the cataclysmic event. Within 30,000 years, the region was teeming with life. Other areas of the Earth took up to 300,000 years to recover from the collision. Researchers are questioning how life recovered so quickly near the impact site.Read More Life Returned Quickly After Dinosaurs were Wiped Out by an Asteroid
