This image of the dolphin head nebula was shot over multiple nights in November 2025 from Starfront observatories in Rockwood, TX.
This nebula is formed from a massive Wolf Rayet star throwing material into space with a ferocious stellar wind, leading to an ionized sphere around a soon to explode star. The blue emission comes from ionized oxygen, a common feature in nebulae formed by Wolf-Rayet stars.
