In late June, you can connect Mars, Saturn and Scorpius’s brightest star Antares to make a nifty right triangle in the southern sky at nightfall.

These photos of the Full Strawberry Moon were taken last night over a period of about 5 minutes. If you look carefully, you can see lots of distortions around the the moon's circumference. There's a very noticeable flattering at 11 o'clock in the leftmost frame. Credit: Bob King

How The Air We Breathe Warps And Distorts The Moon

Many of you saw the full moon rise around sunset last night. I watched it from a place called Hawk Ridge where Lake Superior and the distant Wisconsin shoreline make a perfect setting for watching just about anything rise. A few others made the drive to be there and faced east in anticipation. Just after…
