Eight mysteries of astronomy
What are the biggest unsolved mysteries of the cosmos?
That’s what the journal Science [pay site] set out to identify in its current issue.
“To round up some of the most enduring mysteries in the field of astronomy … Science enlisted help from science writers and members of the Board of Reviewing Editors to choose eight puzzling questions being asked by leading astronomers today,” according to the Huffington Post. “As Robert Coontz, deputy news editor at Science, writes in his introduction to the series, the participants decided that, ‘true mysteries must have staying power,’ rather than being questions that might be resolved by research in the near future. In fact, while some of the topics discussed may one day be solved through astronomical observations, others may never be solved.”
Here, in no particular order, are the biggies:
– What is dark energy?
– How hot is dark matter?
– Where are the missing baryons?
– How do stars explode?
– What re-ionized the universe?
– What’s the source of the most energetic cosmic rays?
– Why is our solar system so bizarre?
– Why is the sun’s corona so hot?
