A night sky is shown that appears mostly red due to pervasive aurora. In the foreground is covered by watery grasslands. Clouds are visible above the horizon. Thin green aurora are visible toward the top of the frame. In the background one can find the Moon, the LMC, SMC, Venus, a meteor, and the band of our Milky Way galaxy.

@APoD
My eyes are not going to be good enough to identify the ISS.

@APoD there should be something that leads to Venus, because every time someone asks me about that really bright thing they saw, it was Venus.

A totally eclipsed Sun is seen in the sky surrounded by a bright corona. In the foreground several people watch it near a large tree. To the right of the eclipsed Sun is the bright planet Venus, while the nearly-as- bright planet Jupiter is to the left.

The sun sets in the distance at the horizon end of a long road over open country. The sunset is very orange, as is the surrounding sky. Telephone poles line the right side of the road.

A large filamentary nebula is shown dominated by red glow but with bits of blue on the lower left. The nebula is shown in a dense starfield surrounded by other faint red-glowing nebulae.

@APoD good old 22 degree halo. It’s nice knowing we still have an atmosphere!

@APoD If the full scale of Andromeda was visible to the naked eye, our entire mythology would have been drastically different. Planets-shmamets, the big oval thing with a bright centre is obviously a major god.

Three large galaxies are shown, the rightmost two in collision. The galaxy on the far right is a large spiral galaxy with one arm connected to an unusual polar galaxy on the left. The smaller galaxy on the far left is thought to be far in the background.
