NASA Astronomy Picture of the Day:

Spooky shapes seem to haunt this dusty expanse, drifting through the night in the royal constellation Cepheus. Of course, the shapes are cosmic dust clouds visible in dimly reflected starlight. Far from your own neighborhood, they lurk above the plane of the Milky Way at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over 2 light-years across and brighter than most of the other ghostly apparitions, vdB 141 or Sh2-136 is also known as the Ghost Nebula. It lies at lower right in the starry field of view. Inside the Ghost Nebula are reddish telltale signs of dense cores collapsing in the early stages of star formation. With the eerie hue of interstellar dust reflecting bluish light from hot young stars of NGC 7023, the Iris Nebula stands out against the dark just left of center. In the broad telescopic frame, these fertile interstellar dust fields stretch almost six full moons across the sky.

Sunrays shining through trees and weak fog near Walchwil, Switzerland.

NOTE: This image is a panorama of Sunrays near Walchwil, Switzerland consisting of 7 frames that were merged or stitched in Kolor Autopano Pro. As a result, this image necessarily underwent some form of digital manipulation. These manipulations may include blending, blurring, cloning, and color and perspective adjustments. As a result of these adjustments, the image content may be slightly different from reality at the points where multiple images were combined. This manipulation is often required due to lens, perspective, and parallax distortions., CC BY-SA 4.0, via Wikimedia Commons. View source.

That's no moon. But you could be forgiven for thinking it was a crescent Moon in the sky. It is a lesser known fact that Venus also has phases. (What about other planets?) The featured image shows Venus seen almost directly between the Sun and the Earth. This happens once every year and a half, and it is like the alignment that happens every month during a new Moon. But the new Moon is dark, while Venus' backlit atmosphere refracts and scatters the sunlight, creating a glowing crescent arc that extends beyond 180 degrees: the tips of this arc are called the "horns". The crescent can be seen with a small telescope or binoculars during twilight, but those with exceptionally acute eyesight may be able to see it with the unaided eye. Ancient Babylonian astronomers may have been the first to study Venus' brightness changes, which are related to its phases. Many other cultures have similar astronomical records, including the oldestsurvivingMaya book.

I waited on
In the late autumn moonlight,
A train droning out of thought—

The mind on moonlight
And on trains.

Blind as a thread of water
Stirring through a cold like dust,
Lonely beyond all silence

And humming this to children,
The nostalgic listeners in sleep,

Because no guardian
Strides through distance upon distance,
His eyes a web of sleep.

NASA Astronomy Picture of the Day:

Jupiter is one of the least lonely planets in the Solar System, at least when it comes to natural satellites. 115 moons have been discovered orbiting Jupiter so far! (Saturn has the most with 293, but who’s counting.) Ganymede and Io, two of Jupiter’s Galilean moons, met in the sky on October 20th, 2026. Today’s video captures the meeting, with Ganymede briefly blocking Io from view. This event, when an astronomical object passes in front of another and either completely or partially blocks it, is called a mutual occultation. The mutual occultations of Galilean moons are rare to witness because they require Earth’s edge-on view of their orbits. This occurs once every 6 years when Jupiter reaches its equinox and appears less “tilted”. Ganymede is also casting its shadow on Jupiter’s right side. Any fictional Jovian species within the shadow would experience a solar eclipse!
