Image: Hubble peers at galactic cherry blossoms
The galaxy NGC 1156 resembles a delicate cherry blossom tree flowering in springtime in this Hubble image. The many bright “blooms” within the galaxy are in fact stellar nurseries—regions where new stars are springing to life. Energetic light emitted by newborn stars in these regions streams outwards and encounters nearby pockets of hydrogen gas, causing the gas to glow with a characteristic pink hue.
