M31Greetings 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 65 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.

weatherWhat's in the Sky Tonight (Saturday, April 23, 2016)


  • Sun - Sunset occurs at 7:42 pm (MDT). Civil twilight ends at 8:08 pm. Astronomical twilight ends around 9:10 pm.
  • Moon - Waning gibbous moon rises at 9:11 pm.

Bright Planets

  • Mercury - In the evening sky (in Aries). Mercury sets at 9:14 pm. This is a good week to catch a glimpse of this elusive planet. Look about 10-15° above where the Sun sets (in the west) about 30 minutes after sunset. Mercury will slowly dim, but is easily visible for the next few days.
  • Venus - In Pisces. Shines very low in the East just before dawn. Rises at 6:00 am (April 24st). Venus is moving into the Sun's glare and is becoming very difficult to see in the morning twilight.
  • Mars - Mars is high in the eastern sky for much of the night (in Scorpius). Rises at 10:19 pm, and is brightening rapidly. Mars and Saturn are now separated by around 8°. Mars has begun retrograde motion, so the angular distance between Mars and Saturn has now begun to increase.
  • Jupiter - In Leo. Jupiter rises well before sunset, and is high in the sky throughout most of the night. Jupiter sets at 4:19 am
    • Jupiter's giant red spot transits at about 1:20 am.
  • Saturn - In Ophiuchus. Rises at 10:48 pm. Saturn is high in the sky at dawn.
