Orbiting above Earth’s atmosphere, Hubble observes galaxies like NGC 6951 in visible and infrared light, capturing details that ground-based telescopes cannot. Its images have illuminated how galaxies form, evolve and recycle their material through generations of star birth and death.
In Hubble’s recent image, NGC 6951 unfurls its graceful spiral arms, covered in red nebulae glowing with hydrogen gas, a key fuel for new stars.
