Two more SETI Institute planetary scientists now have asteroids bearing their names, an honor! The International Astronomical Union's Working Group for Small Body Nomenclature recently approved the names (20749) Graykowski and (29969) Tiscareno, honoring Dr. Ariel Graykowski and Dr. Matthew Tiscareno for their contributions to planetary science. The names were announced in the latest WGSBN Bulletin, which includes 208 newly named minor planets. Learn more: seti.org/news/two-seti-…

NGC 6503 is nicknamed the "Lost-in-Space Galaxy” because of its unusually isolated location at the edge of a vast, nearly empty region of space known as the Local Void. Most galaxies are found in groups, clusters, or along filaments where neighbors are relatively common due to gravitational clumping. In contrast, NGC 6503 sits on the boundary of the Local Void—a huge, underdense stretch of space at least 150 million light-years across that appears almost completely devoid of stars or other galaxies. This “cosmic desert” makes the galaxy seem lost or stranded in an otherwise empty expanse. This is a 24 x 120s shot with an RC10.

Hello Everyone, here is my latest capture - Comet 10P/Tempel. My photo shows something different. We can actually see the orbital dust trail, with particles ejected from the comet over hundreds of years. I used my Celestron RASA telescope and ZWO ASI533MC color camera.

#PPOD: One Hour of Satellites 🛰️ This image shows #satellites crossing the night sky above the northern #Atacama Desert in Chile over just one hour. It is a stack of a time-lapse video taken on 15 October 2025 about two hours after sunset. A few streaks are caused by planes and can be easily identified by their blinking colored lights, but most trails are due to satellites. In the foreground, we see the dome of ESO’s Extremely Large Telescope (ELT), the world’s largest optical/infrared telescope, currently under construction atop Cerro Armazones. Behind it, we see the lasers of ESO’s Very Large Telescope (VLT) at Paranal Observatory, 22 km away from the ELT. Credit: F. Kamphues, @ESO / M. Kornmesser #planetaryscience
