Bombardment of Earth’s surface by asteroids six or more miles long likely delayed the accumulation of oxygen in Earth’s atmosphere. This, in turn, likely delayed the development of complex life on the planet, according to new research that included UC Riverside scientists.
Paleontologist Nigel Hughes has earned one of the highest honors in his field, an achievement made even more remarkable because last year’s winner was another UCR paleontologist — Mary Droser, his wife.
When the world’s most powerful telescope launches into space this year, scientists will learn whether Earth-sized planets in our ‘solar neighborhood’ have a key prerequisite for life — an atmosphere.
By joining NASA on their newly announced missions, UC Riverside is hoping to learn how Venus went from pleasant, Earth-like planet to blistering wasteland.
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.
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.
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.
