Image from the Voyager II flyby of Neptune in August 1989 (NASA). In the middle is the Great Dark Spot, accompanied by bright, white clouds that undergo rapid changes in appearance. To the south of the Great Dark Spot is the bright feature that Voyager scientists nicknamed "Scooter." Still farther south is the feature called "Dark Spot 2," which has a bright core. As each feature moves eastward at a different velocity, they are rarely aligned this way. Wind velocities near the equator are westward, reaching

The lunar nearside (left) is a contrast between dark (craters) and light (mountains) surfaces that has been fancied as the Man in the Moon. Lunar terrain types are still designated by their 17th century name maria and terra (brighter features also known as uplands or highlands; right). Images by NASA.

Is there a reason why this particular half of the Moon locked with Earth, or was it pure coincidence that it didn’t “turn its back” on us?

A bacterial cell (elongated shape in the center) inside a glioblastoma tumor cell, as seen through an electron microscope. The black dots within the bacterium are engineered antibodies carrying gold particles that bind specifically to a component found only in bacterial cell envelopes and not in human cells
