Dusty regions like these are often the places where stars form. In fact, there are two notable stars—V633 (top left of center) and V376 Cassiopeiae (bottom left)—in this image from the Hubble Space Telescope.
These stars have yet to start fusing hydrogen in their cores, and continue to accumulate mass. As they do this, much of the material they ingest gets shot back out as energetic jets. For these young stars, these jets can contain as much mass as Earth has.

ALT TEXT: A protostar in the process of forming. Above the center, at 11 o’clock, is a bright, white star. To the bottom right of this star is a large cavity, surrounded by dark brown gas and dust. This surrounding dust fills the image with the exception of another small cavity toward the bottom left. At about 4 o’clock in this cavity, there is another bright, white star. Smaller white stars are spread throughout the image.

Image taken by Alexandros Maragos
There was a supermoon yesterday (August 19th), which means that the moon appears larger and brighter than usual! Alexandros Maragos took this image as the blue supermoon was approaching its peak at the Temple of Poseidon in Greece. What an incredible image!
Wow - the visible star at the center of the planetary nebula is an A-type giant star. It's the companion of the white dwarf which spawned the nebula itself. (Loved the pic so much I had to read about the object a little).

Man sees what he wants to see, and so it is with the Dark Nebula LDN 1235. This collection of dust in the constellation Cepheus is very reminiscent of a shark. At just 650 light years away, it is just around the corner.

Did you know that there are 5 known dwarf planets in our solar system? Everyone knows Pluto, but there is also Ceres, Haumea, Makemake and Eris.
