When summer only comes around every 120 years, the summer solstice is a pretty big deal. As we celebrate #SolsticeSaturday, learn about the seasons on Triton, Neptune's largest moon: s.si.edu/2IkVeat

Okay, stargazing is officially cancelled for tonight. Boo! But maybe it will be clear this weekend for our various Solstice Saturday festivities around the Smithsonian? Check out the all-day @airandspace offerings here: airandspace.si.edu/events/solstic…

We're supposed to have stargazing tonight. The weather is not looking hopeful. We'll make an official decision soon (this is the projected radar for 9:00 pm). Excuse us while we go obsess over a bunch of other weather sites...
