'''Tyler Eugene Nordgren''' (November 18, 1969) is an [[astronomer]] and professor of [[physics]] at the [[University of Redlands]].<ref>{{cite web|title=Tyler Nordgren|url=https://www.redlands.edu/study/schools-and-centers/college-of-arts-and-sciences/undergraduate-studies/physics/meet-our-faculty/tyler-nordgren/|website=University of Redlands|accessdate=15 March 2017}}</ref>

==Education== Nordgren earned a B.A. in physics from [[Reed College]] and an M.S. and Ph.D. in [[astronomy]] from [[Cornell University]].

==Research== Before joining the University of Redlands in 2001, Nordgren was an astronomer at the [[United States Naval Observatory Flagstaff Station]] and [[Lowell Observatory]].<ref>{{cite web|title=Tyler Nordgren|url=https://www.redlands.edu/study/schools-and-centers/college-of-arts-and-sciences/undergraduate-studies/physics/meet-our-faculty/tyler-nordgren/|website=University of Redlands|accessdate=15 March 2017}}</ref>

In 2004, with six other astronomers and artists, Nordgren helped develop [[MarsDial]]s, functioning sundials that [[NASA]]'s [[Spirit (rover)|''Spirit'']], [[Opportunity (rover)|''Opportunity'']], and [[Curiosity (rover)|''Curiosity'']] rovers carried with them to [[Mars]].<ref>{{cite web|title=Tyler Nordgren|url=https://www.redlands.edu/study/schools-and-centers/college-of-arts-and-sciences/undergraduate-studies/physics/meet-our-faculty/tyler-nordgren/|website=University of Redlands|accessdate=15 March 2017}}</ref><ref>{{cite web|title=Tyler Nordgren Biography|url=http://www.tylernordgren.com/biography/|website=Space Art Travel|accessdate=15 March 2017}}</ref>

Nordgren also designed the giant sundial that resides on the wall of Appleton Hall at the [[University of Redlands]] and is accurate within 10 minutes.<ref>{{cite web|title=North American Sundial Society|url=http://sundials.org/index.php/component/sundials/onedial/658|website=North American Sundial Society|accessdate=20 March 2017}}</ref><ref>{{cite web|title=Physics, up close and personal|url=http://www.redlandsdailyfacts.com/article/ZZ/20060702/NEWS/607029917|website=Redlands Daily Facts|date=7 May 2013|accessdate=20 March 2017}}</ref>

For the past five years, Nordgren has been traveling around the U.S. to educate the public about what [[eclipses]] are and how the opportunity to see the [[total solar eclipse]] on August 21, 2017 should not be missed.<ref>{{cite web|title=I Was Robbed of My Eclipse Experience.

==Collaboration with U.S. National Park Service== Nordgren has been a member of the National Park Service Night Sky Team since 2007, working with the [[U.S. National Park Service]] to protect the night skies and promote astronomy education in [[List of areas in the United States National Park System|U.S. national parks]].<ref>{{cite web|title=Tyler Nordgren|url=http://www.redlands.edu/study/schools-and-centers/college-of-arts-and-sciences/undergraduate-studies/physics/meet-our-faculty/tyler-nordgren/|website=University of Redlands|accessdate=20 March 2017}}</ref><ref>{{cite web|title=Tyler Nordgren Biography|url=http://www.tylernordgren.com/biography/|website=Space Art Travel|accessdate=20 March 2017}}</ref>

Nordgren has helped document the parks' night skies with photography that has been on display in galleries from New York City to Flagstaff, Arizona, and is on display in a number of national parks.<ref>{{cite web|title=Tyler Nordgren Biography|url=http://www.tylernordgren.com/biography/|website=Space Art Travel|accessdate=20 March 2017}}</ref> The Acadia Night Sky Festival has featured many of his photographs.<ref>{{cite web|title=Acadia Night Sky Festival|url=http://www.acadianightskyfestival.com/Gallery/Gallery.aspx|website=Acadia Night Sky Festival|accessdate=20 March 2017}}</ref><ref>{{cite web|title=Acadia Night Sky Festival|url=http://www.tylernordgren.com/exhibitions/acadia-night-sky-festival/|website=Space Art Travel|accessdate=20 March 2017}}</ref> Nordgren has also developed a poster campaign in conjunction with the National Park Service to “See the Milky Way” in America’s parks where “Half the Park is After Dark.”<ref>{{cite web|title=Milky Way Posters|url=http://www.tylernordgren.com/milky-way-posters/|website=Space Art Travel|accessdate=20 March 2017}}</ref>

His 2010 book ''Stars Above, Earth Below: A Guide to Astronomy in the National Parks'' (Praxis, 2010) was published as a way to spread the message of the importance of protecting the night sky.<ref>{{cite web|title=Tyler Nordgren Books|url=http://www.tylernordgren.com/books-1/|website=Space Art Travel|accessdate=20 March 2017}}</ref>

==Professional affiliations== Nordgren was elected to the board of directors of the [[International Dark-Sky Association]] (IDA) in 2011.<ref>{{cite web|title=Tyler Nordgren Biography|url=http://www.tylernordgren.com/biography/|website=Space Art Travel|accessdate=20 March 2017}}</ref> He is also a member of the [[American Astronomical Society]].<ref>{{cite web|title=Tyler Nordgren|url=http://www.redlands.edu/study/schools-and-centers/college-of-arts-and-sciences/undergraduate-studies/physics/meet-our-faculty/tyler-nordgren/|website=University of Redlands|accessdate=20 March 2017}}</ref>
