For those wondering what`s the amazing grouping of bright stars in the western sky, it`s Venus and Jupiter! Venus is the brighter of the two.

Jupiter is bright in the western sky at sunset, next to the brighter Venus.

Saturn is past opposition, but still visible most of the evening.

Venus is bright in the western sky after sunset.

Venus Jupiter Conjunction with Regulus

Image of the Venus Jupiter Conjunction taken on the MAS Observatory grounds by longtime member Tom Schmidtkunz. The bright "star" is Venus and Jupiter is just to the upper left. These two "stars" point to the star Regulus (the brightest star in the constellation Leo) which is at the far upper left. Tom used his Canon T3i DSLR, with a Canon 28-135 lens, shot at about 70mm. It was a 5 second exposure. Click here to see this and other MAS member images in our Showcase.   

Partial Solar Eclipse on Oct. 23th was obscured in the Milwaukee area because of clouds. Our next chance will happen on Aug. 21, 2017. That one will be a total eclipse if you're willing to drive a bit. The path of totality goes through southern Illinois and Missouri! It's not too early to start planning. Click here for details.
