Standing over four hundred eighty feet tall and weighing nearly seventeen million pounds, it is the foremost instrument with which to study the global physical properties of galaxies. Students actively observed nearby galaxies with the GBT, and after the observing session, they processed the data to determine the mass and velocity of neutral hydrogen gas in each of the target galaxies. \u201cThe GBT is one of the most sophisticated scientific instruments in the world,\u201d says Cannon. \u201cFor students at a liberal arts college to be able to use such an instrument in a classroom setting is truly remarkable. In this case, the student experience went light years beyond the typical bounds of a classroom\u2014providing a glimpse into how professional astronomers acquire and use observational data to further our understanding of the cosmos.\u201d<\/p>","protected":false},"excerpt":{"rendered":"<p>Students view the galaxy with some of the most sophisticated instruments available in this astronomy course.<\/p>","protected":false},"author":5,"featured_media":18383,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[3],"tags":[],"class_list":["post-18338","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-academics","mediatype-photogalleries","collections-physicshomepage"],"acf":[],"aioseo_notices":[],"fields":{"article_type":[5],"flickr_photoset_id":"","youtube_id":"","square_thumbnail":false,"press_photos":false,"story_title":"","story_caption":"","rotations":[130],"maps":false,"marker_title":"","marker_text":"","geographic_location":false,"feature_embed":"","custom_link_url":"","news_icon_name":"","image_options":false},"_links":{"self":[{"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/posts\/18338","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/comments?post=18338"}],"version-history":[{"count":3,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/posts\/18338\/revisions"}],"predecessor-version":[{"id":18395,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/posts\/18338\/revisions\/18395"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/media\/18383"}],"wp:attachment":[{"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/media?parent=18338"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/categories?post=18338"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.macalester.edu\/news\/wp-json\/wp\/v2\/tags?post=18338"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
