Absolutely incredible 💫✨💫✨💫✨💫
Can you believe this extended, luminescent ribbon is a spiral galaxy? It's like our Milky Way but seen directly from its side

Believe it or not, this long, luminous streak, speckled with bright blisters and pockets of material, is a spiral galaxy like our Milky Way.
It is oriented directly edge-on to us

The bright blue spiral galaxy NGC 6951, 78 million light-years away in Cepheus, has a starry history and a supermassive black hole at its core. It has hosted six supernovae in 25 years. Hubble captured this stunning image in visible and infrared light.

One thing I learned TA'ing for Alex Filippenko was that letting students make arbitrarily detailed cheat sheets was a fantastic way to let certain students organize their thoughts and distill class information. A learning experience that helped them on the test much more than the cheat sheet did!
We allow students to use handwritten „cheat sheets“ in the written exam of the introductory astro block course. This time, for the first time, we asked for those “cheat sheets” to be handed in, along with the examen. And I’m awed by the handwritten microfiche some of the sheets represent :-) 🔭⚛️🧪

Intriguing: The spiral galaxy UGC 5460 recently hosted two apparent “supernovae”—but it turns out one was actually a luminous blue variable, a rare star type that erupts dramatically yet survives the explosion.

This may not look like it, but this long, bright band, dotted with bright nodes, is indeed a spiral galaxy viewed edge-on, much like viewing our Milky Way sideways.
