Cave nebulae
Cave nebulae (Sh2-155), an emission nebula complex in the constellation Cepheus. North is at top. Emission nebulae (HII regions) are clouds of gas which glow as hydrogen gas they contain is ionised by radiation from hot stars within them. The nebulae are named for the dark protrusions into the northern edge of the nebulae. This may be due to an obscuring dark nebula; gas and dust which blocks out light from behind it

EDITORS COMMENTS
This print showcases the mesmerizing beauty of the Cave Nebulae, also known as Sh2-155, located in the constellation Cepheus. The image portrays a complex emission nebula that spans across the frame, with its northern edge adorned by intriguing dark protrusions. Emission nebulae like this are formed when clouds of gas become illuminated by ionization caused by radiation emitted from hot stars within them. In this case, hydrogen gas is responsible for creating a breathtaking glow that permeates throughout the entire nebula complex. The name "Cave Nebulae" derives from these enigmatic dark formations at its northern boundary. Scientists believe that these shadows could be attributed to a mysterious dark nebula composed of gas and dust which obstructs light from behind it. As we delve into this extraordinary snapshot captured by Science Photo Library, we are reminded of our profound connection to the cosmos and our relentless pursuit of understanding its mysteries. This image serves as a testament to humanity's unwavering curiosity about space and our continuous exploration into astrophysics, cosmology, and stellar formation. Let this awe-inspiring photograph transport you on an imaginary journey through time and space as you contemplate the wonders hidden within this celestial masterpiece - a true testament to evolution unfolding before our eyes.
