4/8 Of this cosmic total, normal matter accounts for just 100 zetta-suns, mostly hydrogen (75%) and helium (25%) formed immediately after the big bang.

A stunning image showcasing the Bubble Nebula (NGC 7635) and the open star cluster M52. The Bubble Nebula, a 10 light-year wide cosmic bubble blown by a massive star, contrasts beautifully with the much larger, 25 light-year wide M52 cluster containing thousands of stars. Both celestial objects reside in Cassiopeia and are captured against a rich backdrop of stars and interstellar gas, creating a mesmerizing deep-space scene.
