Astronomers Without Borders (AWB) is a U.S.-based organization founded by Mike Simmons, dedicated to spreading astronomy throughout the world and connecting people through this universal interest.

[1] The group was founded in 2007,[2] and achieved official tax-free status in 2009,[3] which was the International Year of Astronomy (IYA2009).

AWB sponsored several events that year, including The World At Night (TWAN), and assisted in the IYA2009's Global Cornerstone Project 100 Hours of Astronomy.

Utilizing important historical and natural settings across the globe, The World at Night created wide-angle images of the sky, in order to show the universality of star-gazing.

100 Hours of Astronomy ran April 2–5, 2009, the goal of which was to get as many people across the world to look through optical telescopes.
