On Second Thought, Polaris Really Does Seem 434 Light Years Away
sciencehabit writes with this excerpt from Science Magazine "Last November, astronomer David Turner made headlines by claiming that one of the sky's best known objects—the North Star, Polaris—was actually 111 light-years closer than thought. If true, the finding might have forced researchers to rethink how they calculate distances in the cosmos as well as what they know about some aspects of stellar physics. But a new study argues that distance measurements of the familiar star made some 2 decades ago by the European Space Agency's venerable Hipparcos satellite are still spot on."
Yes, that's why we call it science. If it were never wrong, it would be religion.
Like the autism/vaccination link, Piltdown man was a deliberate fraud exposed by scientists themselves, to me these and other famous frauds are strong evidence that science works as advertised. For an honest man capable of introspection, the scientific method (eventually) weeds out wishful thinking, propaganda, and fraud, this is it's strength. It's weakness is in the undocumented assumption that all involved are honest men acting in good faith.
