Exercises in Astronomy
The object of the series is to present varioussmall projects that will pass on some of the excitement and satisfaction in scientific discoveryto the students. Using elementary geometricaland physical considerations, the students will beable to derive answers that are comparable withthe results of much more sophisticated analysesdescribed in the scientific literature.Click on the relevant flag to download the file in that language

Booklet 3 - Exercise 1
Uses the geometry of the ring of debris that formed around supernova 1987A (SN1987A) to determine the distance to the Large Magellanic Cloud.

Booklet 4 - Exercise 2
The period and apparent magnitudes of Cepheid variables in the distant galaxy M100 are measured and, using the Period-Luminosity relationship, the distance to the galaxy is determined.

Booklet 5 - Exercise 3
By measuring the angular expansion velocity of the Cat's Eye Nebula through images taken in 1994 and 1997, and using tangential velocity measurements the nebula's distance can be calculated.
