Welcome!
Greetings from the professional and amateur astronomers who comprise the Astronomical Society of Las Cruces (ASLC). The club was formed in 1951 by a group of dedicated astronomers including Clyde Tombaugh, who had discovered Pluto just 21 years earlier. For nearly 60 years, we've been sharing a little bit of the universe with our community under our beautiful Southern New Mexico skies.
The club has a variety of ongoing observing, education and public outreach programs. We host a public Moongaze each month, offer beginning astronomy courses and support countless star parties for schools, scouts and various organizations. We also hold a meeting each month which includes a featured presentation.

Fantastic Planetary Alignment Plus Meteor Shower on August 12
Thursday, August 12 will offer a rare treat for visual observers. Four planets will be visible in the western sky at evening twilight. Mars, Venus and Saturn will be within 6 degrees of each other, while Mercury will be found just a few degrees above the horizon. A thin (3.5 day) crescent Moon will add to the beauty of the alignment. Binoculars will probably help you see Mercury along the horizon. The other planets will be bright enough and high enough to see unaided.
August 12 is also the peak of the Perseids Meteor Shower. The Perseids are considered by many to be one of the finest annual meteor showers with rates typically in excess of 50 per hour. Observers in the SW United States will have a chance to observe the peak of the meteor shower between dusk (Aug 12) and to 1 am (Aug 13). The crescent Moon will have set, so if the weather cooperates, we could see 100 or so meteors per hour from a dark viewing site.
So find yourself a comfortable chair and a dark viewing location (as far away from the city's light pollution as possible), and enjoy the show. Admission is free!
August Presentation - Navajo Cosmology: A Sophisticated View of the Univers by Paul Temple
Remember studying about Greek gods and goddesses in school? If you liked soap operas then you liked Greek Mythology! Edith Hamilton's book was required reading for many but definitely hard to keep the players straight! Navajo cosmology on the other hand, is simple and deeply profound. It presents a look at the universe as it is and does so in an entertaining way. The "winter" stories that are told to the children are highly entertaining and have an added element of chaos science as well. The Navajo universe is based on 4's, 4 worlds, 4 sacred directions, 4 sacred rocks and 4 sacred mountains. This blend of 4's weaves together to build the universe as it stands today. Come join us as we explore Navajo Cosmology!
The presentation will be given in room 77 of the Dona Ana Community College (main branch) at 7:30 on August 27th.
ASLC Photo of the Week - Comet McNaught by Rich Richins
Comet McNaught's long ion tail sweeps across the telescopic field of view (a negative image is inset). Remarkably, the ion tail easily stretches past background star cluster NGC 1245 (upper left) in the constellation Perseus, about 1.5 degrees from the comet's lovely greenish head or coma. The coma also sports a short, stubby, dust tail.
The image was captured by Rich Richins at ASLC's Upham dark sky site. Rich used a C11 outfitted with a Hyperstar 3. A Canon T2i was used to capture the images. The image was selected as the Astronomy Photo of the Day for June 17 (2010).
Clicking on the image will bring up a larger copy of the image.
