"400 Years of Jupiter's Moons: From Galileo's Telescope to the Galileo Spacecraft"

Stargazers and others intrigued by our solar system can learn more about Jupiter’s moons during an upcoming presentation by two Redlands professors.

The presentation “400 Years of Jupiter’s Moons: From Galileo’s Telescope to the Galileo Spacecraft” will be given by Redlands professors Tyler Nordgren and Julie Rathbun on Tuesday, Jan. 26 at 5:30 p.m. in the university’s Casa Loma Room. Tickets are $18 and include dinner.

The professors will explore the dynamics and changes to the moons of Jupiter since Galileo Galilei invented the first telescope and discovered the four satellites orbiting Jupiter in January 1610.

Rathbun received a NASA grant of more than $275,000 from the agency’s Jupiter Data Analysis program to lead a team of researchers studying data collected during the New Horizon Spacecraft Mission in 2007.

The primary goal of the initial mission was to study Pluto, but some data on Jupiter’s system also was collected along the way and is being studied. Data collected by the Galileo Spacecraft Mission from 1995 to 2001 also will be highlighted.

Rathbun has spent several years studying a moon of Jupiter known as Io, along with its volcanoes.

Nordgren is an astronomer and has worked with the Spirit and Opportunity Mars Rover team. In 2004, he was one of seven astronomers and artists who converted the Spirit and Opportunity Mars Rover camera calibration targets into functioning sundials.

Nordgren also recently completed a trip through 12 U.S. National Parks, where he photographed the night skies for an upcoming book.

Reservations are required and can be made by contacting Chris Deyo at 909-748-8308 or

Thurber, an English bulldog, is the University's mascot.

He is named after Clarence Howe Thurber, University president from 1933-37.
