On the cusp of Autumn, the cosmos are offering some sights that might be familiar, and some that are often overlooked

The Harvest Moon was once a necessary component to quality farming. Now, not so much. "The world has changed since, but we still retain the traditional name," says Bob King of the Harvest Moon, this year happening on September 26th.

Tonight (Tuesday the 15th) there is a possibility of aurora. Though it's tough to lock down exactly when we might see signs of the northern lights, Bob's best guess is sometime between 10:30pm and midnight.

And for a sight that isn't nearly as talked about, the Zodiacal Light can be seen in the mornings when you look to the east. A tilted cone of light will stand out from the rest of the pre-dawn sky. But what is it? "It's dust," says Bob King. "That dust comes from comets... asteroid collisions, and some of the dust even comes from the planet Mars."

You can hear Astro Bob's Backyard Astronomy every other Tuesday at 8:20am on Northland Morning.
