The ballpoint pen played a huge role in my learning process when I first started sketching. Back then, I would randomly jot down whatever was on my mind onto any scrap of paper, watching it slowly take form. Those were special times. Happy #BallpointPenDay, fellow earthlings!
First example of dark matter structure from Euclid!
Scientists have put together pieces of evidence collected by Euclid, the #DarkUniverse detective 🕵️, to reveal the dark matter structure in the galaxy cluster Abell 2390 👉 www.euclid-ec.org/euclid-start...

NEWS: Gravitational lensing by a globular cluster + #NASAWebb = deepest spectrum of a little red dot. Multiple lines (literally) of evidence suggest this dot is a supermassive black hole enveloped by a dense gas cocoon, also known as a black hole star: https://news.stsci.edu/4fpl2Wc
To learn what distant 🌟or 🪐 are made of, astronomers read hidden signals in their light. From IR to UV, every molecule leaves a signature. It takes the whole range to read the universe.
This month, let's celebrate the full spectrum—in our cosmos & community!

“Calculus for the Practical Man” by J.E. Thompson
This is the book Richard Feynman used to self-teach calculus around age 13
Feynman obtained it from his local library, lied to the librarian claiming it was for his father, and took detailed notes, as high school offered no calculus instruction.

Bro tried to pop a shuvit but the 3D physics engine of this universe couldn’t handle a 4D cross-section and just vomited the board’s vertex data everywhere.
NASA plans to announce the four-person crew for the Artemis III mission today at 11:30 a.m. ET.
The mission is currently slated for launch in 2027 & will test docking capabilities between the Orion spacecraft and one or more lunar landing systems in low Earth orbit. www.nasa.gov/news-release...

For Ballpoint Pen Day, the original patent filed by László Bíró (Hungarian journalist) in 1943.
It was the first commercially successful design, later purchased by Marcel Bich (aka BIC) in 1950.
