February 2018
Saturday February 24th from 1pm to 3pm at the Nature and
Wildlife Discovery Center

How old is the light that comes from the Sun?  How much fuel is the sun burning per second?  
What would happen if the Sun simply disappeared?  Have you ever seen a solar flare or sun
spot in a Solar Safe telescope?  Saturday February 24th from 1pm to 3pm the Southern
Colorado Astronomical Society and Nature and Wildlife Discovery Center (formerly known as
Nature and Raptor Center of Pueblo) will hold a Solar Gaze next to the Coyote Grill and
everyone is invited!

Our Sun is a massive nuclear fusion engine, providing warmth and light, sustaining life on
Earth.  So powerful it creates weather in space. Join SCAS as we explore our local star with
specialized telescopes built to allow safe and direct viewing of the Sun.  See the very “surface”
of the sun churn; observe flares, loops, sun spots and prominences, some several times larger
than the Earth.  SCAS will have information on hand for visitors to take home with them from
NASA to continue learning and exploring once the event has ended.  All ages are welcome to
enjoy this amazing opportunity.
Thursday February 15th at 7pm CSU-P, the Math and Physics Building room 103
The Celestial Yardstick

How on Earth… or for that matter any other planet… can we possibly know the distance to
objects in space?  Sure, we’ve been to the moon, we have rovers on Mars, we even have a few
satellites that have now entered interstellar space, and we know how far away they are.  But
these are meager distances when you consider our galaxy, even more so the Universe.  Do we
have an unbelievably long tape measure? Do we have the inside track with galaxy-hopping
aliens?  It boils down to good old-fashioned human ingenuity. But how?

Thursday February 15th Professor Emeritus Howard “Cork” Hayden will take us on a journey
far outside our solar system, beyond our Milky Way Galaxy, past our local group, to the edge
of the inconceivable, to find a number and discover how we know this.

Accompany the Southern Colorado Astronomical Society as we trade miles for light years at
CSU-P, the Mathematics and Physics Building room 103, beginning at 7pm.  We’ll have hot
liquid refreshments such as coffee, tea, hot chocolate, apple cider available free of charge.  
We’ll also have fellow star gazers, space enthusiasts and amateur astronomers enjoying the
knowledge of the night sky.   There is no charge to attend, and you need not be a member of
the society to participate in this wonderful opportunity to learn about our vast universe.  
Discover Your Inner Astronomer!
