Killer agentic AI idea: change my passwords when requested, enter them when prompted, and enter the codes for two factor authentication.

....meanwhile, in Chile....the 39-meter (128-feet) Extremely Large Telescope (ELT) project is humming along. Note the white pickup truck in the upper left, for scale. Amazing.

Zepbound week 19. Hit the median study 20 week result 9 days early which is exciting and promising, but was helped by some yard work sweat on a hot day. 53.6 pounds lost. 12.7%. Onwards. Also super excited Lilly direct just released the last two higher doses for the $500/mo

Happy Summer Solstice! 🌞 Compared to the year 2000, summer now arrives about 8 hours earlier—thanks to Earth’s slow axial precession. Even in just 25 years, the shift is measurable. #SummerSolstice #Astronomy

I had a chance to catch up with Jared Isaacman about his run for NASA administrator, his future and of course, jets! I'm always excited to learn more about what Jared's got going on!!! Thanks for your time Jared! Enjoy!

The Minor Planet Center has designated 3I/ATLAS = C/2025 N1 (ATLAS), or informally "Comet ATLAS", a new interstellar comet that is currently about 4.5 AU from the Sun and screaming through the solar system at 58 km/s (130000 mph)

summary of proposed Senate funding for NASA & NSF coming out of the CJS afaik: 33.9 billion top-line number: -keeps SLS and Orion – “also funds NASA science and NOAA”, “important funding for NSF”. Will need to see the granular breakdown but looks ~flat budget vs FY24/25

This is a stunning reversal of fortunes for NASA from the US Senate - incredible job to all of you who wrote to your Senators!! This still has to go back to the House so make sure to let your Representatives know that you want this ratified.

House: $6B for science. No report yet. But not the massive cut proposed appropriations.house.gov/sites/evo-subs… appropriations.house.gov/sites/evo-subs…

Always nice to have past research results validated (and cited). ui.adsabs.harvard.edu/abs/2025A%26A.… Nice updated analysis and interesting result.

New paper! Allow me to introduce TARS = Torqued Accelerator using Radiation from the Sun. TARS (yes inspired by Interstellar!) is a rotating light sail that's capable of launching chip sats into interstellar space using only radiation from the Sun, so let's dive into how it works
