🎃 Halloween’s roots are written in the #stars.🔭🧪

Before candy & costumes, it marked a cross-quarter day — when ancient #skywatchers tracked the Sun’s halfway point between #equinox & #solstice.

🪐 #Halloween #Astronomy is TOMORROW!

🌅 Serendipity! On her trip to Australia, the #ASP’s Vivian White captured a stunning partial solar eclipse at sunrise—likely seen only by her & a few others awake on the plane, as clouds hid it from the islands below. A rare moment, perfectly timed. #Eclipse #Oz #EclipseAtDawn

🌌 BREAKING: Mars may have left us a message. #NASA’s Perseverance rover has discovered potential #biosignatures — clues that life may not be unique to Earth.
🔭🧪

“This is the closest we’ve come to recognizing that life on Earth is not unique.”

Katherine Johnson: Math to the Moon 🚀

In 2016 Katherine Johnson became the first recipient of #ASP’s Arthur B.C. Walker II Award, honoring African American achievement in #astronomy & diversity in #science.

Her legacy reminds us: inclusion and discovery must always rise together. ✨ #WomenInScience

💫 Born #OTD in 1918, Katherine Johnson calculated the trajectory for John Glenn’s Friendship 7 flight — math that paved the way to the Moon. 🔭🧪

Her brilliance, courage, & joy in the work remind us: the impossible becomes possible when we dare to calculate the stars. #WomenInScience #HiddenFigures

Born #OTD in 1919 Margaret Burbidge helped reveal one of the great truths of the cosmos — that the atoms of life were forged in the hearts of stars. She then broke barriers to ensure women could study them.

We are made of starstuff & all deserve the chance to discover it. #Astronomy #WomenInScience
