One topic that gets lots of coverage in the pseudoscience circle is the so called Face on Mars.Outrageous claims on this "face" ranges from ancient astronauts, aliens to something to do with Jesus!Here are some links on the topic:
- Article in Space.com saying that Mars Face Breaks Under Questioning
- Another article: The Face on Mars: Unmasked by New Images
- Yet another article: Science and the Teachable Moment discussing how the recent exploration of Mars can be used to teach proper science and counteract pseudoscience.
Hope these are somehow useful.
