John Wesley Powell is one of the iconic explorers of the American West. A teacher, botanist, geologist, and amputee, he is probably best known for his 1869 and 1871 explorations of the Colorado River.

Just outside Moab between the cold, fast-flowing water of the Colorado River and the slow, warmer waters of the Matheson Wetland Preserve stands a newly constructed escape passage for larvae of the endangered razorback sucker.

According to Utah's Division of Air Quality, roughly 50% of Utah's air pollution comes from vehicle emissions. The Utah Foundation and the Utah Clean Air Partnership, or UCAIR, are studying alternative fueled cars as a way to lessen the amount of pollution in the air.

Research tells us that early springs can offset the impacts of climate change. The earlier green-up makes for a longer growing season, and more carbon dioxide captured from the atmosphere. But we haven’t been able to tell if spring is coming earlier for conifers in the mountains – until now.

New research has brought us closer to understanding the composition of the earth’s interior – and it is less uniform than previously thought.


When asked which Solar system world has the most water most people would say the earth has the most water. Although 70% of the earth’s surface is covered by water only 0.12% of Earth’s total volume is liquid water.

Utah has a reputation for being a good place for families, and a new report by the Georgetown Center for Children and Families suggests that the voter-approved Medicaid expansion passed this year could make it even better.


You may have heard the name OSIRUS-Rex in the news lately. It is a NASA-sponsored spacecraft that was launched on the 8th of September 2016 and has recently entered into orbit around the asteroid Bennu, a small spinning top shaped asteroid composed of gravel like material.

Urban deer conflicts can be frustrating when deer eat garden vegetables and deadly when deer are involved in car accidents. Utah's Division of Wildlife Resources reccently made changes to eliminate the relocation aspect of the urban deer program.

Bacterial infections can cause a variety of symptoms from mild intestinal discomfort to death. Recent research could lead to a new form of antibiotics by shutting down bacteria’s injection system.

Polaris: AKA The North Star

May 9, 2019

Polaris is the proper name for what is often referred to as the North Star. For several thousand years it has served as a signpost in the sky and points northward to all those who view it. Of all the stars it is unique because it appears to be almost stationary in the sky while all the other stars appear to rotate around it.

Cutler Marsh and the Bear River provide wonderful habitat for birds - and bird-watchers - in Cache Valley. Utah State University’s beautifully treed campus also has nice habitat for birds, but at a cost: perishing when hitting a window.

Driven To Succeed: Race Day Has Finally Arrived

May 9, 2019

The go-cart track at the Utah Motorsports Campus in Erda is a winding loop of asphalt almost a mile long. It is surrounded by the rest of the campus: several large warehouses storing race cars, mechanical equipment of various types and concession counters offering cold drinks, but mostly… asphalt.

UPR Science Reporter Jennifer Pemberton examines air quality in Cache Valley and beyond. This story originally aired in May 2013.

Saturn In Retrograde

May 3, 2019

From the Earth we view the brighter outer planets Mars, Jupiter, and Saturn moving in their orbits around the Sun in an easterly direction.  At times these planets seem to stop in their eastward motion and reverse direction towards the west for a few months before they resume their normal eastward motion   Astronomers call this retrograde motion. 

Moon Meet Antares, Jupiter And Saturn

May 3, 2019

For the next few mornings in the pre-dawn sky look south and you will see the bright red star Antares, followed by King Jupiter to the left and the ringed planet Saturn to the left of Jupiter.  

In the UPR original series Driven To Succeed, we’ve been following seven college freshman and their mentors as they work to build a wirelessly powered electric car. In this second installment, we get to know the students a bit better, as they work through the trials of engineering a car using brand new technology.

Revealing Historic Winter Climate Using Tree Rings

Counting the number of tree rings tells us how old the tree is but new research reveals how these rings can tell us more about historic winter climates. 

During this first installment of the UPR original series Driven to Succeed, we follow seven college freshman designing and building a solar-powered electric car using a charging system that allows the driver to power the car in motion. 


The star Arcturus glows brightly in the eastern sky in the spring and summer months. It is the fourth brightest star in the sky. It has a distinct yellowish color and when noticed in the eastern sky you will know that spring is about to arrive. 

Farout And FarFarOut with Blaine Dickey

A group of astronomers using the Japanese Subaru 8-meter telescope, located on the top of the mountain Mauna Kea in Hawaii has discovered an object in the extreme outer portions of the solar system on November 18, 2018.  


Sirius is the most luminous Star in the Sky and is easily observed this month about 1/3rd of the way up the southern sky around 9 p.m. Only our Sun, the moon, Venus, and Jupiter, are brighter. Sirius is the 10th closest star to the earth being only 8.7 light years away, about twice the size of our sun, and about 20 times brighter. 

Vernal Equinox-Full Moon with Tom Westre

Apr 23, 2019

Tomorrow we wake up to a new season. Spring begins at 3:44 p.m. MDT— the moment of the vernal equinox. It occurs when the Sun crosses Earth’s equator from south to north. We look forward to longer and warmer days. 

Zodiac With Tom Westre

One of the exciting adventures of astronomy is to find other planets like the earth orbiting other stars. The first such planet was found in 1992. On March 6, 2009, NASA launched a planet-hunting satellite called Kepler. Its job was to stare at a spot in the sky containing 150,00 stars,  in the Constellation Cygnus, looking for dips in starlight as an orbing planet passed between us and its sun. Kepler collected this data in two missions.  

New Horizon Spacecraft With Blaine Dickey

Apr 23, 2019

The New Horizon Spacecraft was launched on its journey to the outer solar system on January 19, 2006. It arrived at the minor planet Pluto more than nine years later on July 14, 2015. It revealed an amazing amount of detail about Pluto that was previously unknown, such as kilometer high mountains made of solid ice, craters, cry-o-volcanoes, and plains made of nitrogen ice.

The Planet Mercury With Blaine Dickey

Apr 23, 2019

The famous astronomer Nicolaus Copernicus first proposed that the sun rather than the earth was at the center of the Solar System. Legend has it that Copernicus never saw the planet Mercury. This is understandable considering that the planet Mercury hugs the horizon even when at its highest elevation in the sky.
