The red band that crosses Greenland, Iceland, and Spain shows where a total solar eclipse can be seen on Aug 12, 2026. Yellow curves across the map show where a partial eclipse will be visible.

Euler had a knack for looking past the surface of a problem and finding the structure underneath. Bridges became graphs, polyhedra revealed invariants, infinite series led to π, and complex numbers took on a geometric form.

🌘 What does a solar eclipse look like from space? The four Artemis II astronauts witnessed this stunning sight, and thanks to a camera on the spacecraft's European-built solar arrays, the rest of us can enjoy the view too 😎. 📸 NASA

The Moon, seen here backlit by the Sun during a solar eclipse witnessed by the four Artemis II astronauts as they flew behind the Moon. Orion is visible in the foreground on the left. Earth is reflecting sunlight at the left edge of the Moon, which is slightly brighter than the rest of the disk.

Today is total solar eclipse day (in a few select places)! There's a lot of really cool science happening as a result, including a recreation of the famed Eddington Experiment. ICYMI, here's how @sciam.bsky.social covered the original 107 years ago. www.scientificamerican.com/article/107-...

107 years ago, Scientific American covered one of the most ambitious total eclipse experiments ever

The Eddington experiment used a solar eclipse to prove Albert Einstein’s general theory of relativity

The fate of our Sun 😲 Fly to π1 Gruis, a red giant star with about the same mass as the Sun — but 350 times larger & several thousand times brighter. In about five billion years, the Sun will swell to become a similar star. 🔭 1/2

Happy birthday to British-born, American #astrophysicist Margaret Burbidge (1919-2020) who was one of the people instrumental in building our understanding of stellar nucleosynthesis, how nuclei are produced in stars & you and I are all stardust! 👩🏼‍🔬🧪🐡🎢🔭 #histsci She was the 1st author of a monumental

My linocut portrait of Margaret Burbidge shows the astrophysicist in gold in from the shoulders up looking directly at the viewer. She has short hair with a little curl and wears a short-sleeved button down shirt with wide stripes. Behind her in black ink is space complete with stars and galaxies. At the base in the centre is a semicircular diagram (flat side down) of a supergiant star cross section in a radial gradient of yellow to red with small radiating irregular spikes. This is overprinted in black concentric rings labelled from the centre out: Fe, Si,O, Ne, C, He, H. At the bottom is a stellar adsorption spectrum: a thin horizontal strip with rainbow gradient of violet at the left through to red at the right with sporadic black vertical stripes. It is printed by hand on ivory Japanese washi paper, 11” x 14”

If you love astronomy, today is your day. 🔭 If you're lucky enough to live in the right place, you could potentially witness three significant cosmic spectacles: a parade of planets, a total solar eclipse and the best meteor shower of the year.

Happy solar eclipse day! ☀️🌒 This evening people across the UK will be treated to the country's fullest solar eclipse since 1999. Around 90-96% of the Sun will be obscured by the Moon at the peak, which will take place at around 19:00 BST, depending on where you are. Are you going to watch it? 😎

A partial solar eclipse.
