In the coming weeks, there are several things to keep an eye out for in the night sky, including the full Strawberry Moon low in the southern sky, Regulus in conjunction with Mars, and some rather unique clouds.
Noctilucent clouds exist high in Earth's atmosphere, some 50 miles above the surface - almost in outer space. These clouds form around this time of the year as it is when that extremely high part of our atmosphere in the northern reaches of the northern hemisphere becomes cold. That temperature when mixed with moisture and some meteor dust creates sparkling blue ribbons an hour or two after sundown.
And the clock is ticking ever-steadily toward summer. The entire planet will mark the change of the season (onward to winter in the south) at 9:42pm CT on June 20th - the point at which the sun will be furthest from the Earth.
You can hear Astro Bob's Backyard Astronomy every other Tuesday at 8:20am on Northland Morning.
