When it comes to viewing our planets in the evening sky, it has been awhile... If you want to give it a try, there's a chance that you could see Mercury soon (June 29-30). Keep in mind, the best time to view Mercury is typically brief, as it sets about an hour after the Sun.

Tonight, you can witness the LATEST sunset of the year. The sun will officially set at 8:35pm. Enjoy each moment of this summer, because our days will slowly continue to shorten, day by day, through December. #wherethestarshangout

The Strawberry Moon arrives tonight! That is the name given to this month's full moon. By the name of this full moon you know that Strawberry picking is right around the corner....or for us in Wisconsin...has been in full swing for over a week! #wherethestarshangout

Happy Summer...officially at 3:51pm! Our solstices are caused by a slight tilt in Earth’s axis in relation to the plane of its orbit- 23.5 degrees off-vertical. Northern hemisphere summer solstice occurs when the northern half has its closest tilt towards the Sun.
