An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets. Read more.
"Broccoli, along with other plants and microorganisms, emit gases to help them expel toxins. Scientists believe these gases could provide compelling evidence of life on other planets. These types of gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element. This process, called methylation, can turn potential toxins...
"Scientists at UC Riverside are suggesting something is missing from the typical roster of chemicals that astrobiologists use to search for life on planets around other stars — laughing gas. Chemical compounds in a planet’s atmosphere that could indicate life, called biosignatures, typically include gases found in abundance in Earth’s atmosphere today." Read more.
"Using light-capturing proteins in living microbes, scientists have reconstructed what life was like for some of Earth’s earliest organisms. These efforts could help us recognize signs of life on other planets, whose atmospheres may more closely resemble our pre-oxygen planet. The earliest living things, including bacteria and single-celled organisms called archaea, inhabited a primarily oceanic...
"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. These planets orbit an M-dwarf, the smallest and most common type of star in the galaxy. Scientists do not currently know how common it is...
"By joining NASA on its 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."
"UC Riverside is leading one of the NASA Astrobiology Program’s eight new research teams tackling questions about the evolution and origins of life on Earth and the possibility of life beyond our solar system. The teams comprise the inaugural class of NASA’s Interdisciplinary Consortia for Astrobiology Research program. The UCR-led team is motivated by the...
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...
Astronomers have a new tool in their search for extraterrestrial life – a sophisticated bot that helps identify stars hosting planets similar to Jupiter and Saturn. These giant planets’ faraway twins may protect life in other solar systems, but they aren’t bright enough to be viewed directly. Scientists find them based on properties they can...
Carbon monoxide detectors in our homes warn of a dangerous buildup of that colorless, odorless gas we normally associate with death. Astronomers, too, have generally assumed that a build-up of carbon monoxide in a planet’s atmosphere would be a sure sign of lifelessness. Now, a UC Riverside-led research team is arguing the opposite: celestial carbon...
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...
Marilyn Fogel, the Wilbur W. Mayhew Endowed Chair in Geo-Ecology, and Timothy Lyons, Distinguished Professor of Biogeochemistry, will be honored at a ceremony and banquet during the 2018 AGU Fall Meeting in Washington, D.C., in December. Both professors are faculty in the Department of Earth Sciences in UCR’s College of Natural and Agricultural Sciences. Only...
"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...
" 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
"The earliest instrumental records of Earth’s climate, as measured by thermometers and other tools, start in the 1850s. To look further back in time, scientists investigate air bubbles trapped in ice cores, which expands the window to less than a million years. But to study Earth’s history over tens to hundreds of millions of years...
"If we’re looking at Mars, or planets in solar systems far, far away, how can we tell whether they support life? Researchers at the University of California, Riverside will share a $50 million grant from the NASA Astrobiology Institute (NAI) to help answer that question by studying ancient rocks on Earth to determine how oxygen...
