Some 322 light-years away in the constellation Libra lies one of the most extreme and hottest worlds discovered by astronomers so far. Launched into Earth orbit last December, the European Space Agency’s shiny new exoplanet-hunting satellite CHaracterising ExOPlanet Satellite (or CHEOPS) spotted exoplanet WASP-189b, a gas giant circling close to one of the hottest known stars with a planetary system.

In order to keep water from evaporating from the soil, farmers will often cover the ground around their crop plants with sheets of polyethylene plastic. There could soon be a more eco-friendly alternative, though, in the form of soybean oil-coated sand.

Farmers often need to regulate soil temperature, reduce weeds, and minimize water loss. Agricultural mulch can help farmers do so.

The monsoon season — that period from mid-June through September that each year brings rains to the Mojave Desert and other areas of the Southwest from the tropical coast of Mexico — has been a dud this year.

Within 20 years, northern Washoe County may be the epicenter of persistent wildfires driven by increased temperatures and prevalent drought brought about by climate change.

Giant hordes of blood-sucking mosquitoes have reportedly swarmed livestock to death in Louisiana this month, the latest gift 2020 has brought to Americans.

Has there ever been life on Mars?

A rock tumble at the Grand Canyon revealed fossil footprints that researchers say are among the oldest in the park.

Fossilized animal tracks discovered in the Grand Canyon were likely left by a reptile some 313 million years ago, among the oldest found on Earth, a UNLV professor said.

In the American Southwest, native desert bighorn sheep populations found in landscapes with minimal human disturbance, including several national parks, are less likely to be vulnerable to climate change, according to a new study led by Oregon State University.

Finding fossil footprints at the Grand Canyon isn’t particularly unusual. The expansive stretch of red rock is home to an array of formations containing preserved remains of the past.

Geologist Allan Krill was hiking along the Grand Canyon National Park’s Bright Angel Trail with a group of students in 2016 when he spotted it: a fallen boulder lying just off the side of the trail, with curious markings that resembled footprints. Krill, who was visiting the University of Nevada, Las Vegas (UNLV) from Norway, sent photos of his find to an old friend and colleague, Stephen Rowland, a UNLV paleontologist.
