@BarackObama Well, @BarackObama, since you asked...check this one out when you get the chance :)

A meteorite may have crashed through the roof of an N.J. home, police say https://t.co/njV9KPsvGh

For those that didn't think I could work astronaut lasagna, Buzz Lightyear, and licking rocks into an alumni magazine spot, this one is for you!

The Brennecka household decided that the best way to start 2023 was by crawling around in a mud volcano. Alternative ideas welcome. #Colombia #Totumo #Geology #showertime

On Dec. 5, 2022, a team at LLNL's @lasers_llnl conducted the first controlled fusion experiment in history to achieve fusion ignition. Also known as scientific energy breakeven, the experiment produced more energy from fusion than the laser energy used to drive it.

@eruptionsblog Might have to get the old soapbox out and find the town square. This internet thing is rough.

[Greg Brennecka @GregBrennecka]

@eruptionsblog Well, I always wanted a way to avoid pesky reviewers, and since HarperCollins let me draw a prehistoric Flava Flav, I just couldn't resist.

[Greg Brennecka @GregBrennecka]

@Opinionatedhjby Absolutely, glad to hear it 😀

You know what magical historic places could use more of? Golf carts! And what better place to park them? #Petra

Book of the Day: Impact by @GregBrennecka

Have you ever wondered how giant space rocks that killed the dinosaurs and blasted off Earth's early toxic atmosphere led to Tom Selleck's Mustache?
If so 🎧⬇️

@SNMilam Obviously IMPACT should be on this list :) But more seriously, anything by Mary Roach or Bill Bryson. And to watch...something with Han Solo in it always makes me feel better. Wishing you a speedy recovery!

If #nuclear material were found somewhere it shouldn't be, nuclear #forensics is how #NNSA would determine where it came from and how it got there. Learn more about this cutting-edge science. 🧑‍🔬⚛️⚗️

@FutureJurvetson @mikeolson @NatureComms @NASAGoddard You are exactly correct about the publisher & the appendix. But, to be fair, the publisher's assumption is also correct, unfortunately. Which is exactly why I wrote the book in the first place. Third graders, on the other hand, love reading about isotopes and mass spectrometers.

[Greg Brennecka @GregBrennecka]

@FutureJurvetson You must have a very nice collection 😀

[Greg Brennecka @GregBrennecka]

Certainly one of the few podcasts out there that touches on terraforming Mars, book illustrations, and skinny-dipping.

[KJZZ Phoenix @kjzzphoenix]

Meteorites are known for destruction, but @GregBrennecka says life on Earth wouldn't exist without them. He talked about it with @markwbrodie.

Is it a bad sign you are already giving my book away? @lithub :)

[Greg Brennecka @GregBrennecka]

@codydschultz Hah, yes, very specific for a pre-AMA... No major evolution since last year, CAIs formed super early and are just isotopically different in a lot of ways - hopefully you can come up with some good explanations!
