This science news story highlights a new initiative by the Hubble Space Telescope to image distant galaxies. The program uses gravitational lenses to image galaxies that are otherwise too distant and faint for the telescope to image. The story... (View More) includes information describing how gravitational lenses are similar to optical lenses. The article also includes a description of parallel fields - a set of observations done in tandem with the gravitational lens observations that will result in six additional HUDF-type observations of the sky. Star Witness News is a series of articles, written for students, that are inspired by Hubble Space Telescope press releases. Supplemental education materials include vocabulary, discussion questions and answers, and identifies relevant Common Core State Standards for English Language Arts. (View Less)

NASA scientist, Neil Gehrels, serves as your guide to this online lesson on gamma ray tools, which focuses on advances in detector technologies since the 1980s that have enabled us to capture and image high-energy phenomena. Dr. Gehrels explains... (View More) different methods for detecting and imaging high-energy particles, how they work, and the advantages and disadvantages of each, using examples and imagery from NASA missions. (View Less)

In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood,... (View More) Milky Way, Local Group, Supercluster, and the observable Universe. The full version of this activity involves students doing simple math computations, however it can also be done without the math. There are some inexpensive materials involved, as well as a powerpoint presentation. It is intended for grades 8-12, but can be adapted down for lower grade levels. (View Less)
