Powerful Christmas Day winds gusting up to 114 mph severely damaged UC Lick Observatory on Mount Hamilton, forcing the nearly 140-year-old facility to close while officials headquartered at UC Santa Cruz assess structural damage and begin repairs expected to take months.

Great article about NASA's next planetary defense mission. Planetary defense has a lot of interlocking parts, and all the DARTs we can build won't help if we don't have the Rubin Observatories and NEO Surveyors (and their predecessors and successors) to find problem objects before they find us.
NEW: When she worked at NASA’s JPL, Amy Mainzer used to rack up high scores on the 1979 Atari game ASTEROIDS. Very apt, now she’s in charge of a space mission that will save the world from killer asteroids.

Some folks said we were too harsh in our episodes on on John Forester and Vehicular Cycling. This amazing video from Not Just Bikes suggests we weren’t harsh enough.
I'm a longtime fan of Not Just Bikes, but his 95(!) minute video on John Forester and Vehicular Cycling is truly his magnum opus.
If you are even remotely interested in the history of bicycling in America, it is worth a watch.
