Empirical astronomy/Quiz

The three images on the right record emission events for AT2018cow. The first shows the galaxy Z 137-068. The second down on the right has two markers ending close to the fuzzy bright source AT2018cow. The third down on the right is a sequence of dated images.

"Astronomers using ground-based observatories caught the progression of a cosmic event nicknamed "the Cow," as seen in these three images. Left: The Sloan Digital Sky Survey in New Mexico observed the host galaxy Z 137-068 in 2003, with the Cow nowhere in sight. (The green circle indicates the location where the Cow eventually appeared). Center: The Liverpool Telescope in Spain's Canary Islands saw the Cow very close to the event's peak brightness on June 20, 2018, when it was much brighter than the host galaxy. Right: The William Herschel Telescope, also in the Canary Islands, took a high-resolution image of the Cow nearly a month after it reached peak brightness, as it faded and the host galaxy came back into view."

Empirical astronomy is a lecture about an approach to understanding astronomical phenomena. A portion of it is a mini-lecture empirical radiation astronomy for a quiz-section as part of the radiation astronomy course on the principles of radiation astronomy.

You are free to take this quiz based on empirical astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!
