TUCSON, Ariz. (KOLD News 13) - Astronomic minds, here is an upcoming event just for you.
The Tucson Amateur Astronomy Association will be hosting an online discussion on volcanism and cyro-volcanism in the solar system via Facebook on Jan 8, 2020.
The online event runs from 6:30-7:45 p.m.
A special guest will discuss examples of silicate volcanism on Earth and Mars, and evidence of cyro-volcanism on Jupiter’s moon, Europa.
Scientists say ‘silica’ influences lava viscosity. Volcanic magma high in silica is usually more explosive, while magma with lower contents allows for a more fluid substance.
According to NASA, cyro-volcanoes are some of the most intriguing features in the solar system. They’re said to erupt water, ammonia or methane instead of the molten rock we’re used to. Cyro-volcanoes form on icy moons and other planetary objects.
And those interested in viewing seasonal objects around the night sky, a second talk will follow.
The organization says anyone is invited to join.
