Dear Eastern Time Zone of the USA: Right now you’re all in twilight, most beneath crystal clear skies. High in the west the Moon flies It’s gazing down and away — at Jupiter & Saturn, sitting close to each other, getting closer by the day. — PolitiTweet.org

@GelfandGenna @wef With our without climate change, the high gravity of gas giant planets empowers them to keep their large quantities of lighter gasses such as H2 and He. Smaller planets can only hold onto rarer, much larger molecules (O2, N2, H2O, CO2) bcause they don’t move as fast. — PolitiTweet.org
