Galaxies, Part 1 of 3
You've found part one of a three-part series entitled "A Practical Guide to the Universe." Hosted by Tom Selek, this older clip shows, describes, and invites viewers to think about what galaxies are. The color, motion, and brightness of stars are the key scientists use to determine the distance between galaxies.

Counting Galaxies with the Hubble Space Telescope
In this counting galaxies worksheet, students use a photograph taken by the Hubble Space Telescope and they divide the field into 16 square areas. They find the average number of galaxies in the cells, they find the area of one of the cells and they determine the total number of galaxies the Hubble Space Telescope detected in the photograph.

A Glimpse of the Most Distant Galaxy
In this most distant galaxy worksheet, students use a Deep Field image taken by the FORS camera at the ESA-VLT observatory to answer 4 questions about the redshifts identified in the field. They use an on line redshift calculator to determine look-back times for each galaxy.

The Speed of Galaxy Q2125-431
In this speed of a galaxy worksheet, students use a given equation for the speed of an object and they use the spectral lines for Hydrogen Alpha and Beta from the Seyfert galaxy to answer 6 questions. They determine the observed wavelengths, the rest wavelengths, the velocities of the wavelengths and if the galaxy is moving towards or away from the Milky Way Galaxy.

Rotation Velocity of a Galaxy
In this orbit of stars in galaxies worksheet, students are given an equation that models the orbital speeds of stars as they relate to their distance from the nucleus of a galaxy. Students solve 5 problems using this equation and determine how fast stars orbit a galaxy, the maximum velocity of a star and the years it takes a star to complete an orbit.

A Galaxy Up Close
For this Sombrero Galaxy worksheet, students observe infrared images taken by the Spitzer Infrared Telescope and the Hubble Space Telescope. They answer 9 questions about the details of the images such as the radius of the stellar component, the thickness of the dust disk and the diameter of the bright nuclear core.

Galaxies: A Cosmic Journey Through the Universe
Sometimes open ended is good. This five-minute silent video shows various objects found in space. Learners will see Earth, the Milky Way, stars, nebulae, comets, quasars, and galaxies. Because there is no narration this video could be used for any number of purposes, paused, discussed, or made available for interested learners.
