Citizen Science Project Nets a New Asteroid, and It's a Close One
Members of the public helped the University of Arizona's Catalina Sky Survey spot a previously unknown near-Earth asteroid on its orbit around the sun. The asteroid, TW 2023, has no chance of colliding with Earth.

A Gift from Space: UArizona-led OSIRIS-REx Mission Delivers Largest-ever Asteroid Sample to Earth
The delivery from the asteroid Bennu, seven years after the spacecraft launched, marks the end of the space-voyaging phase of the mission. Scientists will now study the rocks and dust to better understand the origins of life on Earth.

Mt. Lemmon SkyCenter
Mt. Lemmon SkyCenter is an exceptional science learning facility located at Steward Observatory's "sky island" observing site. The SkyCenter builds upon the uniqueness of the 9,157 foot summit of Mt. Lemmon and the extensive knowledge base at the University of Arizona to deliver educational programs.

Space Drafts
Space Drafts is Tucson’s flavor of Astronomy on Tap. Talks are held one Wednesday of every month at one of Tucson’s finest microbreweries, The Borderlands Brewing Company. Space Drafts is free and open to all ages (of humans and dogs alike).

HiRISE
We have a simple philosophy: HiRISE is “the people’s camera” because we believe that knowledge about Mars belongs to everyone.
