Solstice
"In the depth of winter I finally learned that there was in me an invincible summer." -Albert Camus
As the year draws to a close, we approach a very special time of year, at least from an astronomical perspective. This Saturday, December 21st, will mark the Winter Solstice in the Northern Hemisphere (or the Summer Solstice in the Southern), or the date where the Earth's axis is tilted its maximal amount away from (or towards) the Sun, as viewed from an observer in the Northern (or Southern) Hemisphere.

"Tell me what you feel in your room when the full moon is shining in upon you and your lamp is dying out, and I will tell you how old you are, and I shall know if you are happy." -Henri Frederic Amiel
Tonight is a special night, although not for the reasons you may think. Yes, it's just a few days after Christmas and before the new year, but tonight is the night of the Full Moon closest to the winter solstice.

"The secret of life is honesty and fair dealing. If you can fake that, you've got it made." -Groucho Marx
Now that the solstice is behind us and summer is officially here (for most of us), it's time to start enjoying the greatest fruits of the season. With the technical difficulties of the great scienceblogs migration (hopefully) behind us, I think I've discovered how to successfully bring a weekly song back to my weekend posts, too! Have a listen to Aimee Mann as she sings one of my favorites of hers,
Little Bombs.
Out where I live, in Oregon, now is the season that one of my favorite fruits…
"Soon the earth will tilt on its axis and begin to dance to the reggae beat to the accompaniment of earthquake. And who can resist the dance of the earthquake, mon?" -Peter Tosh
Every year, there are two special days where every place on Earth receives the same amount of sunlight -- 12 hours -- split evenly between night and day: the equinoxes!

Like all known objects that revolve around another due to gravity, the Earth rotates along its journey around the Sun. But on those two days of the equinox (from the Latin, meaning "equal nights"), the Earth's axis-of-…
