There are an estimated 200,000,000,000,000,000,000,000................. stars in the universe

It is big. We are not.

It is likely that all the American flags on the Moon are now white due to Sun’s radiation.

Space fact: We always see the same side of the Moon, no matter where we stand on Earth.

Physics Photo Of the Day:

Lise Meitner and Otto Hahn, shown in Dahlem, 1913.

Lise Meitner was a pioneering nuclear physicist who made key contributions to the discovery of nuclear fission. She worked with Otto Hahn and discovered that fission could be achieved by bombarding uranium with slow neutrons, a key factor in the development of the atomic bomb.

On Valentine’s Day 2023, the Moon will occult Dschubba!
Dschubba, or delta Scorpii, is a B-type star in the constellation of Scorpius. It’s the middle star in the little arc of 3 stars above bright red Antares, the Scorpion’s Heart. On February 14, the 24-day-old waning crescent moon will pass in front of the star, temporarily hiding it from view from some parts of the world.

Two titans of Quantum Field Theory: Richard Feynman and Chen Ning Yang c. 1950s. Both Nobel Laureates.

Yang's best known for his role as co-discoverer of parity violation while Feynman had significant contributions to the development of the QED.

On #ValentinesDay 1990, Voyager was 6.4 bn km away when it turned to see its long lost love one more time before it left for good.

It saw a small pixel sized dot - Earth - where it was born, nourished 🌍🚀🛰

This love story was written in the stars. Literally!💫

Happy 459th birth anniversary to Galileo Galilei, born on this day in 1564.

A polymath and a central figure in the transition from natural philosophy to modern science and in the transformation of scientific Renaissance into a scientific revolution.
