Rho Ophiuchi and Antares Nebulae
These beautiful nebulae shine like jewels in the depths of space, and it's no surprise that capturing them was a complex feat. Tom O'Donoghue of Ireland had to spend 60 hours of exposures on these faint gems due to their altitude in the Spanish sky and some clouds.
"The dust can reflect the light of nearby stars, as seen in the blue and yellow regions," the Royal Observatory noted. "It can also block and absorb the light of more distant stars, appearing brown and black in this image. To the right, a bright star is ionizing a cloud of hydrogen gas and causing it to glow red, while below it, far in the distance, is a globular cluster containing thousands of stars."
