What's happening to this cirrus cloud? Ice crystals are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. For a circumhorizontal arc to be visible, the Sun must be at least 58 degrees high in a sky where cirrus clouds present below. The numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight in a similar manner. Therefore, circumhorizontal arcs are somewhat unusual to see. The featured fire rainbow was photographed earlier this month near West Virginia, USA.

Heart and Soul nebulae in the constellation Cassiopeia
The Heart Nebula (IC 1805) located on the right of this image, has a shape reminiscent of a classical heart symbol. To the top of the Heart nebula, lies The Fishhead nebula (IC 1795) is a part of a complex of star forming regions that lie at the edge of a large molecular cloud.
The Soul Nebula (IC 1871) is visible on bottom left of this image. Both nebulas shine brightly in the red light of energized hydrogen.
Several young open clusters of stars are visible near the nebula centers. Melotte 15 (Heart of the Heart nebula) is a popular target.
Light takes about 6,000 years to reach us from these nebulas, which together span roughly 300 light years.

Quote
The Buddhist allegory of "Indra's Net" tells of an endless net of threads throughout the universe, the horizontal threads running through space, the vertical ones through time. At every crossing of threads is an individual, and every individual is a crystal bead. The great light of "Absolute Being" illuminates and penetrates every crystal bead; moreover, every crystal bead reflects not only the light from every other crystal in the net-but also every reflection of every reflection throughout the universe.

This is the Bubble Nebula! 💭💭💭
This nebula in the constellation of Cassiopeia is blown into a bubble shape by the bright, hot star at its center. The width of the bubble is a whopping 7 light years across, which is 1.5 times the distance from the Sun to our nearest star, Alpha Centauri! 🔥🔥🔥

Saturn’s Aurora! This real image was taken by the Hubble Space Telescope, it shows the gas giant Saturn with it’s Aurora. Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It only has one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive.
