Today is the first day of Autumn. Goodbye shorts and t-shirts, hello cute sweaters and trench coats.

Deep down inside, I’m a geek. An engineer at heart and by education, I do have an appreciation for science. I’ve never really been into astronomy, but I came across some pretty cool happenings going on in our galaxy this week 🙂 So take this as your “current events guide to the solar system“!

Today (9/22) at 3pm Eastern Time,  Jupiter and Uranus will be in conjunction, and less than one degree apart in the sky. You’ll be able to see both of them close to each other just after sunset.

Later tonight, at approximately 11:09pm Eastern Time, the equinox, meaning “equal nights” will begin.

An equinox occurs twice a year, when the tilt of the Earth‘s axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth’s equator.

This means that daytime and nighttime are of equal lengths everywhere on Earth, about 12 hours each.

Tomorrow (9/23)  at 5:17am Eastern Time, since the moon and sun are exactly opposite in the sky, the September full moon will occur. They call this full moon the Harvest Moon because it’s closest to the equinox.

So according to MSNBC, since the two planets and moon are all directly opposite the Sun, you’ll be able to see all 3 of them close together in the sky with your fancy telescopes 🙂 I may not be an astronomy nerd, but I still think that’s pretty damn cool.

In all honesty, when someone says Milky Way, I totally think of the chocolate bar. 🙂
