Astronomers have long wondered whether the configuration of planets in our solar system is common elsewhere in the universe. New results from the longest-running survey of exoplanets helps answer this question.

A new UC Riverside study finds a naturally occurring “earthquake gate” that decides which earthquakes are allowed to grow into magnitude 8 or greater.

New research shows the permanent rise of oxygen in our atmosphere, which set the stage for life as we know it, happened 100 million years later than previously thought. A team including UC Riverside found that oxygen fluctuated dramatically after its early appearance before becoming a permanent constituent of the...

A new UC Riverside study has found the first evidence of sophisticated breathing organs in 450-million-year-old sea creatures. Contrary to previous thought, trilobites were leg breathers, with structures resembling gills hanging off their thighs.

Today’s humans share genes with 555-million-year-old oceanic creatures missing heads.

Scientists aren’t usually able to measure the size of gigantic planets, like Jupiter or Saturn, which are far from the stars they orbit. But a UC Riverside-led team has done it.
