Researchers at the University of Nevada, Las Vegas say the 20 nearby protoplanetary disks observed in the study suggest there may be a greater number of large, young planets in our galaxy than previously expected.

Astronomers have cataloged nearly 4,000 exoplanets in orbit around distant stars. Though the discovery of these newfound worlds has taught us much, there is still a great deal we do not know about the birth of planets and the precise cosmic recipes that spawn the wide array of planetary bodies we have already uncovered, including so-called hot Jupiters, massive rocky worlds, icy dwarf planets, and - hopefully someday soon - distant analogs of Earth.

The City of Las Vegas is partnering with the University of Nevada Las Vegas to assess lead hazards in older homes.

When you’re out hiking, you never know what you might see. You could cross paths with lizards, tarantulas or maybe even something bigger like a javelina. More likely, you’ll also come across the tracks of these critters.

The latest national climate assessment captures the future impacts of a warming planet more completely than reports that have come before it, UNLV geology professor Matt Lachniet says.

It’s time for a dinosaur update.

A few years ago, UNLV researchers were tasked with trying to figure out what kind of prehistoric animal made tracks that were fossilized in the area of Gold Butte National Monument.

Brian Hedlund and Ariel Friel collect microbes living for tens of thousands of years in the subsurface of the earth. By studying these microorganisms, they hope to gain clues about potential life on Mars and other planets.

310-million-year old footprints of a "lizard like-creature" have been unearthed in the Grand Canyon, making them potentially the oldest ever reptile footprints ever found.
