Dying stars, called planetary nebulae, very often have rings such as those seen in this image, astronomers have found.
This photo depicts the Cat’s Eye Nebula, one such dying star. It's 3,000 light years away.

Massive black holes
often
float
in
doughnut-shaped gas clouds which, depending on our line of sight, blocks the view of the black hole in the center.
Using two European Space Agency orbiting
telescopes, scientists looked "edge on" into this doughnut, called a torus, to see features never before
seen
so
clearly. How the doughnut forms, however, remains a mystery.

Mars:

crater:
This false-color image shows visible mineral changes between the materials that make up the rim of the impact crater known as "Endurance." The image was taken by the panoramic camera on NASA's Mars Exploration Rover Opportunity using all 13 color filters. The cyan blue color denotes basalts, whereas the dark green color denotes a mixture of iron oxide and basaltic materials. Reds and yellows indicate dusty material containing sulfates. Scientists are very interested in exploring the interior and exterior material around the crater's rim for clues to the processes that formed the crater.

The

Hourglass
