Welcome to the Wormhole - Ames Area Amature Astronomers window on the web

The Ames Area Amateur Astronomers is a dynamic organization with activities held year-round. Each month at our meeting we present a guest speaker, with exciting lectures about space and astronomy.

                                         September Meeting

Because of the Iowa Star Party, there will be no monthly meeting. At the Iowa Star Party, Lee Ann Willson will be the presenter and her topic is Mira Variables and the Fate of the Earth. Miras are pulsating red giants distinguished by their large amplitude variation in visible light, late spectral types (cool atmospheres), and the presence of emission lines during part of the cycle. The emission lines result from shock waves generated by pulsation that traverse their atmospheres. These stars’ atmosphere are often dusty, an indication of mass loss. The Mira stage corresponds to the onset of devastating mass loss, a process that removes most of the remaining envelope and reveals the degenerate core, a new white dwarf star. After considering what happens with the star itself, I will examine the effects of this future evolution of the Sun on our solar system and Earth, and discuss some ideas for saving the Earth.

The Iowa Star Party will be held September 14-18th 2017.  Watch for updated registration information.

There are two comets that will be visible yet this year - Comet ISON and Comet Lovejoy. Have you seen them?
In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth.
When the sunspot number is high, so is the chance of flares. NOAA forecasters estimate a 50% chance of M-class flares and a 15% chance of X-flares during the next 24 hours.
