This is a PDF guide on how to use ImageJ image processing software to understand and manipulate astronomical images. The guide begins with instructions on how to download ImageJ, plus some additional astronomy-related plugins, followed by directions... (View More) on how to install everything correctly. There are three lessons that will help the user get oriented with some of the most basic image processing skills needed for analyzing astronomical images. There are questions throughout the lesson to help guide thinking. After the lessons is an explanation for how to create a color picture using three different gray scale images. (View Less)
In this activity, children make a mobile of galaxies; patterns and instructions are included. It introduces the different shapes of galaxies and their nomenclature. Note that young children will need assistance from an adult or older child to safely... (View More) complete this activity. (View Less)
The Picture Post Network involves individuals, schools, organizations and communities in a systematic monitoring project of their local environment, especially vegetation health. Digital photographs - taken from the same location and positioned in... (View More) the same direction and orientation - allow individuals, schools, organizations, communities and scientists to monitor a variety of environmental parameters, including plant health, growth, and phenology; erosion and deposition; water levels; and cloud and canopy cover. Participants study change over time in their local area, view NASA satellite imagery on the same days as the pictures, and contribute towards improving their own communities. The website provides instructions for participating, including planning and installing a picture post, monitoring projects, and taking and uploading pictures, and a repository of images. Picture Posts may be added by anyone interested in monitoring a particular location. Currently, Picture Posts sites are active at science centers, schoolyards and gardens, local parks, and nature reserves. (View Less)
This is an activity about how giant dish antennas work. Learners create a "sound cone" and use it to understand how the Deep Space Network antennas pick up radio communications from space.
This guide provides instructions on how to make color pictures using images downloaded from the WISE archive. An overview of what digital images and FITS files are is followed by a discussion on the basic process of how gray scale images are... (View More) adjusted, assigned color, and added together to create a color picture. Five different image processing programs are provided to the users, along with the pros and cons of each program, and links for installing and using each one. There is also a review of the various image artifacts that may be found in WISE images. (View Less)
This interactive, web-based activity allows children to see the universe in many different wavelengths of light - light our eyes can and cannot see. To use the viewer, first select a celestial object (planet, galaxy, etc.), then select an... (View More) electromagnetic wavelength range to view it (e.g., visible, ultraviolet, infrared). Images are from various ground- and space-based telescopes. In addition, background information is provided on the electromagnetic spectrum and selected telescopes designed to detect specific regions of light. (View Less)
This Hubble Space Telescope image shows an especially photogenic group of interacting galaxies called Arp 273. The larger of the spiral galaxies, also known as UGC 1810, has a disk that is distorted into a rose-like shape by the gravitational tidal... (View More) pull of the companion galaxy below it, also known as UGC 1813. The encounter between the two galaxies also has created regions of intense star formation. In the accompanying educational activity, In Search of ... Interacting Galaxies, students investigate galaxy interactions through a level 1 inquiry activity using the images and text from the lithograph and other resources. A level 1 inquiry activity can help prepare students to become independent thinkers. (View Less)
This is a game about planning what to take on a space trip to Mars. Learners will decide on the appropriateness of items to take on a long trip to Mars and take into consideration the effects of zero gravity, limited electrical power, etc.
This is a series of three webpages about how humans and computers communicate. Learners will explore the binary and hexidecimal systems and how engineers use them to translate spacecraft data into images.
This online, interactive "Chutes and Ladders" type of game is for ages 7-9 and can be played with a friend or against the computer. As players land on squares, depending on the described action, they either "leap" frog ahead if they help the... (View More) environment or butterfly "flutter" back if they do not. The website includes a short explanation of why we should care about frogs and butterflies, as well as some facts about some of the activities on the game board and why they are good or not good for the environment. A printable version of the board game is also available. (View Less)
