What's with all the aurora pictures?
The title of this webpage, "Astronomy Undergraduate Research Resources",
was tantalizingly close to fitting the acronym AURORA, which was a
tantalizingly good acronym for an astronomy page! Although I resisted the
temptation to contort the webpage title into "Advancement of Undergraduate
Research Opportunity Resources in Astronomy" or something equally
forced and convoluted, I decided to keep the aurora theme anyway.
To learn about what causes aurorae, this webpage is a good place to start.
