What type of cloud is that? The thundercloud is somewhat unusual as it contains a mammatus cloud on the near end and also produces falling rain on the far end. The cloud is moving to the east as the sun sets behind the camera in southern Canada. In the featured image, sunset colors cross the sky to give the cloud a striking orange and pink hue. The sky is blue. There is a gibbous moon visible on the far right.
The picture is of space dust.

The Chamaeleon Dark Nebulas are dark.
Telescope Live, Heaven's Mirror Observatory is a work of art.
The dark dust of space can have an elegant look. The far-south constellation of Chamaeleon is such a case. Dark dust blocks visible light from stars and galaxies behind it. In this exposure, the dust is seen mostly in light, with its red and near-IR colors giving it a brown hue. The bright star Beta Chamaeleontis is visible just to the right of the center, with the dust that surrounds it reflecting blue light from its primarily blue-white color. There are stars and dust in our own Milky Way, but the white spot just below Beta Chamaeleontis is the galaxy IC 3104 which is far away. Interstellar dust is created in the cool atmospheres of giant stars and then dispersed into space by stellar winds and exploding stars.
