Title: Week 7: Discussion
Course: ASTRON103: The Evolving Universe: Stars, Galaxies, and Cosmology (001) DHH SU18 > Section: Week 7

In the past, astronomy was a small field and in general the observers did not compete with each other but worked on different problems. Now there are many telescopes, and several different groups often work on the same problem. For example, two different groups have independently developed the techniques for using supernovae to determine the distances to galaxies at high redshifts.

Which approach do you think is better for the field of astronomy?

Which is more cost effective? Why?

Note: You must make your own, original response first in order to see other students responses. You can then comment on various responses throughout the week.
