November 18, 2020 (San Diego) – San Diego Supervisors today voted to approve amendments to the county’s Light Pollution ordinance which will provide “Dark Sky Community” designation to both the Julian and Borrego Springs community planning areas.  The action aims to prevent light pollution, enhancing astronomy viewing and related tourism.

The action comes after the Julian Dark Sky Network asked Supervisors in 2018 to create a way for Julian to meet International Dark Sky Association recognition. Borrego Springs was the first California community to receive that designation in 2009.

"Our community is part of the 1% of the U.S. that can still see the Milky Way. Our distance from the urban glow of San Diego's skies and the surrounding mountains help with our sky quality, but preservation must be intentional," the Julian Dark Sky Network's website states.

KEPLER DISCOVERS PLANETARY SYSTEM ORBITING TWO SUNS

Lead author SDSU astronomy professor Jerry Orosz said it's the first transiting circumbinary multi-planet system to be found.

September 6, 2012 (San Diego) -- Astronomers at the International Astronomical Union meeting announced the discovery of the first transiting circumbinary multi-planet system: two planets orbiting around a pair of stars. This discovery shows that planetary systems can form and survive even in the chaotic environment around a binary star. And such planets can exist in the habitable zone of their stars.
