Scottish astronomer Williamina Fleming discovered the Horsehead Nebula in 1888. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, ~1,375 light-years from Earth.

Black-and-white Victorian-era studio portrait of Williamina Fleming, a woman with her dark hair neatly pulled back and up; she wears a dark dress adorned with lace and fabric flowers at the shoulders, a delicate choker necklace, and looks directly with a calm, serious expression. Plain dark studio backdrop. Color photograph of the Horsehead Nebula, a dramatic dark silhouette shaped like a horse’s head rising from swirling reddish-pink glowing gas, set against a starry background with bright stars scattered across the frame.

Happy #AstronomyDay!

A telescope in a park. A stranger showing you Saturn’s rings. A shared sense of awe under a common sky. We don’t all need to be astronomers — but we can all be skywatchers.

"The cosmos is within us. We are made of star stuff."
-- Carl Sagan 🔭🧪

The HQ crew head up to the roof as #AstronomyDay comes to a close.
We will look skyward hoping to spot Alfie’s @alfieandpoppy.bsky.social new star rising and take a moment to reflect.
We will think of those who have crossed 🌈, their families and all of you in the #Hedgewatch community. 💫
A night time scene outside HQ. Brock, Spike and Valerie are on the roof and Brock is looking through his telescope, the rest of the HQ gang are on the ground. In the sky there is a bright star at the top of a cat and butterfly constellation with a rainbow in the background.
