Chandra has observed hundreds of targets in the last 5 years, ranging from
planets and supernovas up to gargantuan galaxy clusters, and has generated
over a hundred press releases and beautiful images. The most popular topics
have been active galaxies, black holes, and neutron stars and mass accreting binaries.
Because active galaxies are incredibly bright galaxies
powered by supermassive black holes, top billing should be given to black
holes as the most popular object observed by Chandra. The most spectacular
Chandra images have been those of supernova remnants, the debris left over
after massive stars have exploded. To complete the Chandra quest, you'll need to be familiar with 20 Chandra observations.
How to Play:
Figure out which Chandra images are featured in the puzzle shown
below (clicking on the puzzle image will bring up a full-sized
version for better visibility).
To show the numbers for each piece of the puzzle, click on the "Show Numbers" link beneath the puzzle. When the numbers are shown, the link will change to "Hide Numbers".
Correctly fill in the form below the image, assigning the
appropriate field (1, 2, 3, etc) to an object name listed in the
pull-down menu next to it. There are more than 20 objects listed
in the pull-down menus; not all will be used.
When you're ready to send your answers, press "Submit". (If you'd like to start over, press the "Reset" button.) Your
answers will be checked and you will be notified whether or not
you correctly named all 20 objects.
The official contest ended on September 24, 2004, but the activity can still be played for enjoyment.
All of the Chandra images included in this activity can be found within the pages of the Chandra Photo Album. Most of the images in the collage are the primary image featured in the photo album page, but some can be found on the "More Images" pages within the object's section. A few of these images are multi-wavelength composites featuring Chandra data as well as data from other telescopes.
