The 2026 @NobelPrize in Physics was awarded today to Dr. Francis Halzen for his work using Antarctic ice to capture and study particles known as neutrinos that share information about distant sources throughout the universe. nobelprize.org/.../physics/2… #NobelPrize #physics #STEM
BREAKING NEWS
The Royal Swedish Academy of Sciences has decided to award the 2026 #NobelPrize in Physics to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.”
Congratulations to Dr. Karl Deisseroth, Dr. Peter Hegermann & Dr. Georg Nagel on being awarded the 2026 @NobelPrize in Physiology or Medicine for their work on optogenetics, which "makes it possible to show how nerve cells shape memories, feeling & behaviors in the living brain."

Happy #FallEquinox! 🍂 Today, the Sun crosses Earth’s celestial equator, marking the official start of autumn in the Northern Hemisphere. It's also the time of year when day and night are nearly equal in length around the globe.

Did you know you can often spot the Moon in broad daylight? 🌙 And that some thunderstorms can produce 100+ mph winds without a tornado? ⛈️ This month's #DaySkyUpdate explores both, plus what to watch for as we approach the September Equinox. Read more:slsc.org/day-sky-update-sept…

Look up tonight.
The Moon will pass through Earth's shadow during a deep partial lunar eclipse visible from much of North and South America and parts of Europe and Africa. As the eclipse deepens, the Moon will appear tinged with shades of red and copper.
ALT A nearly total partial lunar eclipse fills the center of the frame against a dark sky. The Moon is bathed in shades of red, orange, and copper as Earth's shadow covers most of its surface, leaving only a thin, bright crescent illuminated along its left edge. Dark lunar maria and lighter highlands remain visible through the reddish glow. The image was captured during the November 19, 2021, partial eclipse of the full Beaver Moon, the longest partial lunar eclipse in centuries. Credit: NASA

NASA honors the memory of Dolly Parton, who passed away on Aug. 25, 2026.
In 1989, Dolly performed at @NASAJohnson's Rocket Park, alongside fellow musicians Willie Nelson and Kenny Rogers, to an audience of over 12,000 NASA employees and their families.

#FunFactFriday: A day on Venus is longer than a year on Venus! 🔭 Venus takes about 243 Earth days to rotate once, but only 225 Earth days to orbit the Sun. ☀️ For comparison, Earth rotates once every 24 hours, while Mars takes about 24 hours & 37 minutes. 🌏 – at St Louis, MO
