Campus to celebrate 50th anniversary of historic Moon landing

This year marks the 50th anniversary of the historic Apollo 11 Moon mission. To celebrate, the University of California, Riverside, is hosting a free public event on Thursday, July 11, from 6:30-9:30 p.m. Attendees will have an opportunity to learn more about the Apollo 11 legacy, as well as current missions to our solar-system’s planets...

New study dramatically narrows the search for advanced life in the universe

"RVERSIDE, CA – Scientists may need to rethink their estimates for how many planets outside our solar system could host a rich diversity of life. In a new study, a UC Riverside–led team discovered that a buildup of toxic gases in the atmospheres of most planets makes them unfit for complex life as we know...

New NASA research consortium to tackle life's origins

Did life on Earth originate in Darwin's warm little pond, on a sunbaked shore, or where hot waters vent into the deep ocean? And could a similar emergence have played out on other bodies in our solar system or planets far beyond? These questions lie at the center of research in NASA's new Prebiotic Chemistry...

Special journal issue looks for new clues about old life

"Hundreds of millions of years before there was a chicken or an egg to debate, the first complex animals were evolving in parallel with Earth’s rising oxygen levels. But what came first — animals or oxygen? That question is the central theme of a special issue of Emerging Topics in Life Sciences published Sept. 28...

New Picture of Ancient Ocean Chemistry Argues for Chemically Layered Water

"A research team led by biogeochemists at the University of California, Riverside has developed a detailed and dynamic three-dimensional model of Earth’s early ocean chemistry that can significantly advance our understanding of how early animal life evolved on the planet." Read More

Search for Life Beyond the Solar System Topic of Faculty Research Lecture

" Timothy Lyons , a distinguished professor of biogeochemistry in the Department of Earth Sciences and director of the Alternative Earths Astrobiology Center, will deliver the 66th annual Faculty Research Lecture at UC Riverside. The Faculty Research Lecturer Award is the highest honor bestowed by the Academic Senate." Read More

UCR Team Among Scientists Developing Guidebook for Finding Life Beyond Earth

"If you’re looking for a manual on the hunt for alien life, you’re in luck. Some of the leading experts in the field, including a UC Riverside team of researchers, have written a major series of review papers on the past, present, and future of the search for life on other planets. Published in Astrobiology,...

Methane Muted: How Did Early Earth Stay Warm?

"For at least a billion years of the distant past, planet Earth should have been frozen over but wasn’t. Scientists thought they knew why, but a new modeling study from the Alternative Earths team of the NASA Astrobiology Institute has fired the lead actor in that long-accepted scenario." Read More

Low Oxygen Levels May Have Delayed Emergence of Animals

"Records of the earliest animals on Earth extend to roughly 700 to 800 million years ago, despite much older traces of microbial life in rocks deposited 3.7 billion years ago. Multiple factors might have contributed to this delay — but not with equal effect and in ways that are often not well understood." Read More

Oxygen Was Once A Sometime Thing on Earth

"An understanding of the history of Earth is incomplete without an understanding of how and why the planet developed an oxygenated atmosphere. A team of scientists, including Timothy Lyons, a distinguished professor of biogeochemistry, reports new isotopic data in Science Advances that illustrate how photosynthetic cyanobacteria temporarily spiked concentrations of oxygen around 2.5 billion years...
