Public Observatory

This account is now retired. We've had an awesome 7 years chatting with all of you. You can find us over @airandspace sharing astronomy news and events, and reminding you to always keep looking up. Clear skies! #SIObservatory

@Litsas @airandspace The same staff will be involved in creating content. By moving our content to @airandspace, we hope to serve a broader audience of dedicated superfans and astronomy newbies.

@SIObservatory @airandspace Why are you putting all the Observatory social media accounts offline or merge them with the Museum's accounts???? Saving money (because 1 less account = 1 less person needed)????
