‘Monster Eruptions’ at Ritchie Observatory

An active volcanic eruption on Jupiter
An active volcanic eruption on Jupiter's moon Io was captured in this image taken by NASA's Galileo spacecraft. Tvashtar Catena, a chain of giant volcanic calderas centered at 60 degrees north, 120 degrees west, was the location of an energetic eruption caught in action in November 1999. A dark, 'L'-shaped lava flow to the left of the center in this more recent image marks the location of the November eruption.

Join astronomer Dave Fong on a journey through the solar system to find enormous volcanoes and geysers that dwarf their Earthly counterparts at the planetarium show “Monster Eruptions” at the Edwin E. Ritchie Observatory at 7 p.m. Saturday, March 8.

If the sky is clear, astronomers will be on hand with telescopes for public star-gazing.

The show is free to members of the Battle Point Astronomical Association; $2 donation suggested for nonmembers, $5 for families.

The Battle Point Astronomical Association is a nonprofit amateur astronomy organization that operates the Ritchie Observatory and John H. Rudolph Planetarium in the Helix House at Battle Point Park.
