APOD: 2026 February 14 - Roses are Red

Summary: This image features the Rosette Nebula (NGC 2237), a vibrant cosmic cloud of hydrogen gas and young stars that resembles a blooming rose.

Featured as the Astronomy Picture of the Day for February 14, 2026, this image captures the Rosette Nebula (NGC 2237). The nebula is a massive star-forming region where stellar winds from bright, young stars have sculpted the surrounding gas and dust into a rose-like shape. The vibrant red color is produced by ionized hydrogen gas, while the blue-white center is color-mapped to highlight ionized oxygen. These massive stars, though only a few million years old, are already nearing the end of their life cycles.
