Activities include mazes, word searches, connect-the-dots, and coloring.


2. Hot Stories of Cool Science: Star Birth Edition (2013) pdf (2013)
This 26-page ebook for kids (PDF) includes general information on stellar birth: Stars are amazing. They look like tiny pinpoints of shining light that seem to last forever. However, that is not the case. Just like people, stars are born, live for a while, and then die. Let’s find out more about baby stars.

3. OpenFits, Unlocking the mysteries of astronomical image processing pdf (2013)
With a basic understanding of astronomical data and image processing software, you can create your own astronomy images from FITS files. “FITS,” which stands for Flexible Image Transport System, is a digital file format used mainly by astronomers. Check out chandra.si.edu to download FITS files for some of our favorite Chandra images and learn how to compose your own versions of these high-energy astronomy images.

7. The Unexpected: from NASA's Chandra X-ray Observatory pdf (2011)
Looking back on the accomplishments of NASA's Chandra X-ray Observatory over the past dozen years, and trying to predict what it will find in the future, one thing is certain: we can expect the unexpected. This booklet lists some of the expectations for the Chandra mission along with some of the unexpected discoveries.


8. Stellar Evolution pdf (2010)
A star’s ultimate fate depends on its mass. It can fade into obscurity (brown dwarf or red dwarf), become a white dwarf (sun-like stars), explode as a supernova and leave behind a neutron star or a black hole (massive to very massive stars), or be disrupted entirely (white dwarfs in close binary systems, or extremely massive stars).

9. Chemistry & the Universe pdf | flash (2010)
Chemistry, the study of the intricate dances and bondings of low-energy electrons to form the mole-cules that make up the world we live in, may seem far removed from the thermonuclear heat in the interiors of stars and the awesome power of supernovas. Yet, there is a fundamental connection between them.

Information on the overall specifications (size, weight, orbit, etc), spacecraft specifications, science instruments and the telescope system.


15. Einstein All the Time High Res. pdf (2008)
Einstein's fingerprints can be found on virtually every scientific result obtained with Chandra data. These results in turn have expanded our concept of the Universe far beyond what was imagined at the beginning of the 20th century. Three of Einstein's discoveries are described.


16. Chandra Explores "Downtown" in the Milky Way High Res. pdf (2008)
The Milky Way is our home galaxy - a vast rotating spiral of gas, dust, and hundreds of billions of stars. Learn about Chandra observations in the Galactic neighborhood, including supernovas, black holes, neutron stars and more.


17. Galaxy Clusters Optical/X-ray Comparison High Res. pdf (2008)
What is the X-ray Universe? Why observe the Universe with different types of telescopes? These questions and others are answered. Special feature: an activity in which you make an X-ray image of a galaxy cluster.


18. The Universe in a Jelly Bean Jar pdf | flash (2008)
Most of the Universe is dark. The protons, neutrons and electrons that make up the stars, planets and us represent only a small fraction of the mass and energy of the Universe. The rest is dark and mysterious. How can X-rays help reveal the secrets of this darkness?
