Scientists have devised new analytical tools to break down the enigmatic history of Mars’ atmosphere — and whether life was once possible there. A paper detailing the work was published today in the journal Science Advances. It could help astrobiologists understand the alkalinity, pH and nitrogen content of ancient waters on Mars, and by extension...
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...
"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...
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...
"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...
"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
"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
"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...
"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
"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
