The earth has a tilt of about 23.5 degrees, either toward or away from the sun. Earth enters the winter solstice on Dec. 21. Tom Webber and Dr. Reynolds were invited by First Coast Connect Host Melissa Ross to talk about the solstice in her regular Tech Tuesday segment. What's up on earth and what's up in the night sky (and what's not: RIP, Comet ISON) are the subjects, and Webber even touches on what's up in the future, in a Star Trek kind of way.
