The amateur astronomy community is abuzz over a strange phenomenon spotted over Mars last week. Astrophotographer Wayne Jaeschke reports on his website of a “strange feature” over the Martian plain called Acidalia that moves with the planet and seems to rise over the limb.
The discovery has professional astronomers taking note. NASA’s Mars Odyssey spacecraft will try to image the cloud with a camera that can take pictures in visible and infrared light simultaneously.
