This short video (2:01) uses an engaging approach to emphasize the importance of tracking and studying precipitation. The video cast explains how the Global Precipitation Measurement (GPM) mission will use a constellation of satellites to achieve... (View More) global coverage, thereby providing scientists with accurate precipitation data from around the world. In addition to the video, the site contains supplemental text which provides background information on the GPM mission. (View Less)
This short video (4:06) provides an overview of the Global Precipitation Measurement (GPM) mission. This mission will set a new standard for precipitation measurements from space by joining forces with countries around the world, to provide... (View More) precipitation data from nine different satellites, creating the GPM Constellation. NASA has partnered with the Japan Aerospace and Exploration Agency (JAXA), space agencies in France and India, and the operators of meteorological satellites in Europe and the United States to make this multi-nation mission possible.

This is a poster about the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), an instrument onboard the Mars Reconnaissance Orbiter. Learners can find out what it does and how it works, then go online and start exploring the Red Planet... (View More) with real Mars data. (View Less)
This interactive is a graphical introduction to geospatial images from NASA Earth science satellites and encourages exploration of the interconnected nature of Earth’s system by students and the public alike. Explore 25 different Earth images and... (View More) learn key features behind each data set, learn more about the satellite mission that collected the data, and find links to related NASA resources, including multimedia and data. See supplemental links for a link to a poster version of the interactive. The backside of the poster includes information on how and why NASA maps the world, a student section with tools and resources for them to explore and create their own maps, and more. (View Less)
The H-R diagram is a scatter graph of stars, a plot of stellar absolute magnitude or luminosity versus temperature or stellar classification. It is an important astronomical tool for understanding how stars evolve over time. Stellar evolution cannot... (View More) be studied by observing individual stars as most changes occur over millions and billions of years. Astrophysicists observe numerous stars at various stages in their evolutionary history to determine their changing properties and probable evolutionary tracks across the H-R diagram. In this activity, students plot both maxima and minima with corresponding stellar classifications for several variables, and then identify the type of variability: Cepheid, RR Lyrae, Mira or Semiregular. This activity includes background information, a teacher guide, a student activity, and accompanying worksheets. The American Association of Variable Star Observers (AAVSO) and The Chandra X-Ray mission have collaborated to develop this activity. (View Less)
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 website presents basic information and concepts about Cosmology and our current best understanding of the Universe. Cosmology is the scientific study of the large scale properties of the Universe as a whole. It endeavors to use the scientific... (View More) method to understand the origin, evolution and ultimate fate of the entire Universe. Like any field of science, cosmology involves the formation of theories or hypotheses about the universe which make specific predictions for phenomena that can be tested with observations. Depending on the outcome of the observations, the theories will need to be abandoned, revised or extended to accommodate the data. Includes sections on: Big Bang Theory, Big Bang Tests, Beyond the Big Bang, and Our Universe. (View Less)
This website provides instructions on how to find and download images directly from the WISE archive. With a computer and Internet connection, users can access high-resolution, infrared images from the WISE mission. Instructions are provided to... (View More) explain how to get access the images from the archive. (View Less)
In this online interactive, learners will explore how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. Includes audio (and transcription) explaining the diagram.
This is an activity about how the Sun can affect the Earth's atmosphere, specifically the ionosphere. Learners will use real data from a Sudden Ionosphere Disturbance Monitor, or SID Monitor, to identify the signatures in the graphed data that can... (View More) be used to determine the times of sunrise and sunset. Although the SID monitors are designed to detect SIDs caused by solar flares, they also detect the normal influence of solar X-rays and UV light during the day as well as cosmic rays at nighttime. There is a distinct shape to a 24-hour SID data graph, with unique shapes, or signatures, of the graph appearing at sunrise and sunset.This activity is part of the Research with Space Weather Monitor Data educators guide. Use of and access to a Stanford Solar Center SID monitor and the internet is encouraged but not required. Locations without a SID monitor can use sample data provided in the educators guide.
