If you want to bake a cake, you might have to crack a few… comets? 🥚

We’ll never forget you, 3I/ATLAS! 👋🥹
Gemini North, ½ of @GeminiObs, imaged the comet as it traveled away from Earth. Its tail of dust particles appears longer & thinner compared to previous images due to solar radiation pressure moving the dust away from the comet.
