Thank you @astroshark_neo on Instagram for tagging us in your beautiful shot of the Iris Nebula!
"The Iris Nebula
Does anyone else see a keyhole in the cosmos?
This is the Iris Nebula, a brilliant blue reflection nebula surrounded by enormous clouds of interstellar dust, about 1,300 light-years away in the constellation Cepheus.
The blue glow comes from starlight scattering off tiny dust grains. But the dark clouds surrounding it may be even more fascinating. They contain complex organic molecules, including polycyclic aromatic hydrocarbons (PAHs) and fullerenes — carbon molecules that include the remarkable 60-atom spherical structures known as buckyballs. These are some of the building blocks of cosmic chemistry, though their presence doesn’t imply life.
And just how far away is this cosmic keyhole?
In my Cosmic Inch universe, where the solar system is reduced to roughly an inch across, this extraordinary cloud of dust and complex organic molecules is just 22 miles away. A short drive in our miniature universe — yet its light has taken 1,300 years to reach us.
I captured this image over three exceptionally clear October nights in Virginia. Using a Stellarvue SVX 140t telescope and Zwo 2600mm astrophotography camera. Nearly everything you see beyond the blue center is incredibly faint dust, revealed through hours of accumulated starlight.
A keyhole into a universe that is both unimaginably vast and astonishingly intricate."
