You're never too young to learn about the ultimate fate of the cosmos!! 🤩 #EndOfEverythingBook
Update: I have been informed that 7 might be too young to learn about the ultimate fate of the cosmos. Please use the usual parental judgment when discussing cosmic apocalypses with your children.
My 3.5-year-old babynieces are pretty tough, though. I’m sure they can take it. Two 3.5-year-old girls in white sweaters and denim skirts si
In all seriousness: from what I’ve heard some children are VERY freaked out by concepts like the death of the Sun or the end of the Universe; some don’t care at all. It seems to be hard to predict and I am neither a parent nor an expert on child psychology so use your judgment!

I took this photo of the Moon and Mars last night with my phone. It might not be the best photo but believe me when I say they were both GORGEOUS. Or better yet: don’t believe me — go out tonight and see for yourself! A very dark fuzzy image of the nearly full Moon rising over
Now is a great time to look at Mars. It’s unusually close to Earth in its orbit and (for the same reason) pretty much directly opposite the Sun. It’s as though it’s doing its best to be a mirror for the Sun shining back at us, so it’s very very bright. This is called #opposition.
Here’s a diagram of the positions of the planets right now from theplanetstoday.com. You can see that both the Moon and Mars are in the opposite direction as the Sun, so the Moon is close to full & Mars is bright and close. #MarsOpposition A diagram of the Solar System showing the Sun (labeled Sol),

💥 Life on Venus? 😮

Quick thread with links to more info. First, the press release from @RoyalAstroSoc: ras.ac.uk/news-and-press…

Short version: a molecule was detected in the atmosphere of Venus that MIGHT have been produced by life. (It's unclear how else to produce it there.)
New York Times coverage by @shannonmstirone, @kchangnyt, & @overbye: nytimes.com/2020/09/14/sci…

"High in the toxic atmosphere of the planet Venus, astronomers on Earth have discovered signs of what might be life."
New Scientist coverage by @DownHereOnEarth: newscientist.com/article/225441…

"There are no known non-biological mechanisms of making the gas on Venus, so it may be being produced by alien microbes." [Paywalled article]

Here's a thread of reviews of #EndOfEverythingBook -- because they've honestly all been really fantastic and it makes me SO HAPPY to see how much people are enjoying my book now that it's officially out there in the world! ✨📚✨
"'The End of Everything' is a pleasure. Mack’s style is personal and often funny ... I found it helpful — not reassuring, certainly, but mind-expanding — to be reminded of our place in a vast cosmos." -@nytimesbooks

nytimes.com/2020/08/04/boo…
"...like an animated discussion with your favourite quirky and brilliant professor. ... If you need a moment to be distracted from everyday life and journey to the deep cosmic future, I highly recommend 'The End of Everything.'" -@newscientist

Quick thread about my book, "The End of Everything (Astrophysically Speaking)", with FAQ. #EndOfEverythingBook astrokatie.com/book
Q: What's it about?

A: The end of everything! Literally! How the Universe will end, & what that might look like if we were around to see it. There are five possible scenarios covered in the book: Big Crunch, Heat Death, Big Rip, Vacuum Decay, & Bounce. #EndOfEverythingBook
Q: Do I have to have an astrophysics background to understand it?

A: Not at all! It's written for a general audience, by which I mean, I won't assume you have any physics/astronomy background. There are some cool/deep concepts in there, but it's accessible. #EndOfEverythingBook
