Sorry, but with the heavy clouds, significant "chance" of rain, cool temperatures and wind we're reluctantly cancelling sidewalk Astronomy tonight! We had to cancel a school star party last night, and had significant clouds at our Tuesday school star party too. It has actually just started to rain here in Monrovia at 3 p.m. Our next Sidewalk Astronomy is May 23, and don't forget June 13, our next Dark Sky Star Party/campout/potluck at Mojave National Preserve's Black Canyon Group Campground (near the Hole in the Wall visitor center. It's also raining at Griffith Observatory, but there are a lot of free inside events today and tomorrow celebrating the 25th anniversary of the Hubble Telescope launch - check them out here http://www.griffithobs.org/. It's also clouded out up on Mt. Wilson right now! Instead, you might enjoy some of the Hubble Telescope 25th anniversary images including this gorgeous just-released image commemorating the anniversary. http://hubblesite.org/newscenter/archive/releases/2015/12/image/a/ Or some JPL Videos: https://www.youtube.com/user/JPLnews/videos I wish if the rain was going to make us cancel astronomy events, it would at least be a real downpour! -- Jane Houston Jones @jhjones @CassiniSaturn @NASAInsight What's Up?
