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 over 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.

The monthy ASLC meeting will be held on Friday, February 28th at 7:30PM. Dr. Chris Churchill discuss galaxy evolution. Here is a brief summary kindly provided by Dr. Churchill.
We will begin by discussing our developing understanding of galaxies over last 80 years and what our most modern ideas are up the present day. It turns out that the flow of gas into, through, and out of galaxies is where all the action is - that what really governs how a galaxy system evolves is the gas that is dynamically being processed through a large, massive, gaseous region surrounding the galaxy that we call "the circumgalactic medium". The observational and theoretical efforts (including cosmological simulations) currently being leveraged to the solve the open questions will be reviewed, with an eye on the research occurring at NMSU.
ASLC Photo of the Week - M46 by Chuck Sterling
Open Cluster M46 is in constellation Puppis. M46 is about 5,500 light-years away with an estimated age on the order of several hundred million years. The planetary nebula NGC 2438 appears to lie within the cluster near its northern edge (the faint doughnut at the right center of the cluster). NGC 2438 is most likely unrelated since it does not share the cluster's radial velocity, and just happens to be in the same field of view.
The image was acquired from his back yard in Las Cruces, NM, using Images Plus Camera Control 2.0 with a Canon 350d camera on an Astro Tech 8" f/4 imaging newtonian, with an IDAS LPS-P1 light pollution filter and a Baader MPCC (multi-purpose coma corrector). The mount is a Celestron CGE, autoguided by PHDGuide 1.12.3 and a ShoeString Astronomy GPUSB with a Meade DSI-Pro-1 camera on an Orion 80ED f/7.5 refractor.
