Happy Equinox to all Earthlings. Latin for equal-night, today we all get 12 hrs of day & night — except we don’t. FYI: Sunlight crossing from the vacuum of space into Earth’s atmosphere refracts, adding a few minutes more light at sunrise & sunset than we’d otherwise receive. https://t.co/F5HgGsyvtx — PolitiTweet.org

@ledalf No. That’s much too small. Around 70-billion of them pass through your fingernail every second. Be glad they hardly ever interact with your molecules. — PolitiTweet.org

Dear Chicago, Galaxies, black holes, killer asteroids, subatomic particles. They all collide. The topics for this evening. Good to back in town. I missed you. See you at 7pm CT. -Neil https://t.co/83xvJh663h — PolitiTweet.org

@Dpullen66 But then no driving on cloudy day. Or at night. Gotta store the energy for when you don’t have the Sun. That’s what batteries do, which you can charge by sunlight. But there’s no getting around the storage problem. — PolitiTweet.org

@JiDrozd Like Struggle for Freedom and Democracy Day? Has the Czech Republic “moved on” from that? — PolitiTweet.org

@dirttrailhiker @PragmaticSloth Thanks, Micheal, for that backup. Another interesting fact — Earth days were shorter, billions of years ago. Moon tides have been slowing us down the whole time. So a more accurate count is closer to two-trillion. But I felt the precision would distract from the tone. — PolitiTweet.org

**Vaccine Science** I host a podcast, if you didn’t know. Here’s a @StarTalkRadio episode with @IrwinRedlenerMD that’s all about Vaccines, in case you’re not entirely sure how they work, or in case you retain doubts about their efficacy. [Video: 48 min] https://t.co/FryMpnoZWS — PolitiTweet.org

Very glad to hear. Happy to have helped tip the scales. But people shouldn’t get vaccinated because “Tyson said so." They should get vaccinated because of evidence that it’s effective & safe. Or maybe school needs to spend more time on what science is and how and why it works. — PolitiTweet.org

Neil deGrasse Tyson @neiltyson

@Chuck_Huber Thanks for asking. Twitter, of course, does not lend itself to full citations. I derived the number from published COVID-19 death rates of unvaccinated people (about 1,000 per day). And from the polls that show 25% of Republican voters are unvaccinated, versus 5% of Democrats. — PolitiTweet.org

Neil deGrasse Tyson @neiltyson

In case anyone is curious… Right now in the USA, every ten days, more than 8,000 (unvaccinated) Republican voters are dying of COVID-19. That’s 5X the rate for Democrats. https://t.co/vhf2PNhKV7 — PolitiTweet.org

Just a reminder that before anybody had a space program, we didn’t have satellite images of hurricanes, and we largely had no clue what they would do next. https://t.co/bn8mngNmeX — PolitiTweet.org

Dear Science Deniers, (Anti-vaxers, anti-maskers, climate hoaxers, flat-Earthers, etc) You found one another & communicate via stupefyingly advanced technologies that pivot on the discoveries of scientists. Just thought I’d remind you of that fact. Sincerely, Your Smart Phone — PolitiTweet.org

@Devilish21ca Most meteor streaks in the nighttime sky are caused by particles no larger than a pea. So if you re-enetered the atmosphere from orbital speeds, then as you vaporized, you’d be visible to anyone on Earrth with a sightline to you. — PolitiTweet.org

@kevinmitnick Another cool effect is that the sky is often darker between the primary and secondary rainbows than on either side of them. — PolitiTweet.org

Neil deGrasse Tyson @neiltyson

@kevinmitnick You get a second rainbow because not all the light exits the raindrop. Some stays inside for a second round of internal reflection before dispersing on exit. What emerges is a dimmer, larger, and reversed rainbow. — PolitiTweet.org

Neil deGrasse Tyson @neiltyson

@kevinmitnick Nice shot. And if you look carefully, especially in the upper left of the image, you can see the "second-order" rainbow, with color sequence reversed. — PolitiTweet.org

Any month that begins on a Saturday has a “Friday the 13th”. Once every seven years, or so, when February has 28 days **and** begins on a Sunday, it forces March to have a “Friday the 13th” too. The only occasion where “Friday the 13th” occurs in two consecutive months — PolitiTweet.org

Neil deGrasse Tyson @neiltyson

"Friday the 13th" happens just once or twice a year. Exactly as rare as... "Thursday the 12th" or "Saturday the 14th." Or "Friday the 6th." Or "Friday the 20th." Or "Friday the 27th." — PolitiTweet.org

Neil deGrasse Tyson @neiltyson

Each year around this time, Earth plows through the debris-trail of Comet Swift-Tuttle. At our orbital speed of 67,000 mph (30km/s) the particles burn harmlessly in our atmosphere, rendered aglow as shooting stars. Behold the annual Perseid Meteor shower: https://t.co/XGapXfe9BU — PolitiTweet.org
