Questions for Discussion: Astronomical Images in Different Wavelengths
-
Why are some telescopes used on Earth while others are
launched into orbit above Earth's atmosphere?
-
How do the work of scientists and engineers benefit each
other's areas of expertise?
-
What information can be obtained from a conventional photograph
of a human body that cannot be obtained from an X-ray,
a thermograph — an image taken with an infrared
camera that records temperature variations on the surface of
the body, and a magnetic resonance image (MRI) —
an image of internal organs and soft tissues produced with
magnetic fields and radio waves.
What does the X-ray tell that the photograph and other
images do not?
-
Are the images of the human body described above a useful
analogy for someone learning to understand why it's helpful
to create different kinds of images of objects in space?
Why or why not?
