It Comes Around So Rarely, It's All Chance

The origin of the word "happiness" is from the Middle English "hap" which has to do with chance and possibility. As in "happenstance" or per-haps. So hap-iness was originally about the feeling of good fortune/getting lucky; the chance that something could or could not occur, and then it goes your way. Happiness is that specific feeling when something that could have gone horribly wrong goes amazing well.

Powered By SCIENCE

For the last 50+ years, every submarine and aircraft carrier built by the US Navy has been powered by nuclear reactors. What's more, the aircraft carriers have a 50 year service life and only need to be refueled ONE TIME. There has also never been a nuclear related accident on board these ships (two subs have sank, but not because of a failure in the propulsion system).

Within Our Line Of Sight

On December 21, 2020 Jupiter and Saturn will align such that you can see them together in the same telescope, and even with the naked eye. It's called The Great Conjunction.

Edit: To answer some common questions:

1. It should be viewable from most anywhere in the world. In the Northern Hemisphere look southwest. In the Southern Hemisphere look south.
2. The best time to view will be 30 minutes to 2 hours after sunset.
3. If it's cloudy on the 21st don't worry. The 21st is just the date that they're closest. But since the planets move so slowly across the sky it should allow for similar viewing in the several days before and after the 21st.
4. The planets will appear pretty low in the sky so try to find a viewing location where you can see as much of the horizon as possible in the proper direction. Since there are several nights this will be visible it's best to try early to find the right spot.

A Protective Wall

The New "Normal"

Museums are struggling to keep the appropriate humidity levels for their collections because of the lack of foot traffic and people breathing in the buildings due to COVID.

Edit: should say I heard this on the podcast "No Such Thing as a Fish", which I highly recommend, as I'm sure many in this comment chain would as well :) I think, as some have pointed out, "struggle" might not be the right word to have used, but it does appear from the research I did this morning that it is something museums are dealing with due to lack of foot traffic creating a "new normal" of humidity in these places.
