Dust grains older than our Sun found in asteroid Ryugu samples

Washington, DC— Microscopic grains of ancient material that predate our Sun’s birth were found in samples returned from the asteroid Ryugu by the Hayabusa2 mission, according to new work from an international team led by Carnegie’s Jens Barosch and Larry Nittler and published in The Astrophysical Journal Letters. Named after a Japanese folktale, Ryugu is … Read more

JWST to reveal chemistry of ancient galaxies, is taking data for first of six Carnegie-led projects

Pasadena, CA— The first of six projects led by Carnegie-affiliated astronomers will, for the next three days, use the James Webb Space Telescope to make some of the most-accurate measurements ever taken of the chemistry of very early galaxies—studying light that traveled 10 billion years to reach us. Carnegie’s Gwen Rudie and Allison Strom, formerly … Read more

Building Blocks of RNA Spotted at the Center of the Milky Way

Building Blocks of RNA Spotted at the Center of the Milky Way

A team of researchers say they’ve found some building blocks of RNA in a molecular cloud close to the center of the Milky Way. The discovery has implications for theories about how life began on Earth—and perhaps elsewhere. The molecular cloud is named G+0.693-0.027. The team of astrophysicists, astrobiologists, and chemists conducted a survey of … Read more

New analysis sheds light on diversity and ecological footprint of marine RNA viruses

New analysis sheds light on diversity and ecological footprint of marine RNA viruses

Community- and “species”-level analysis on Global Ocean RNA sequences sampled from waters worldwide has shed light on the poorly understood diversity and ecological footprint of marine RNA viruses, according to a new report. The findings underscore the important roles marine RNA viruses play in the ocean ecosystem. Viruses are ubiquitous in all domains of life … Read more

Breakthrough may reveal the origin of life on Earth, and maybe on Mars

Breakthrough may reveal the origin of life on Earth, and maybe on Mars

A study on the potential origin of life titled “Catalytic Synthesis of Polyribonucleic Acid on Prebiotic Rock Glasses“has been published in the journal PLOS Genetics. Researchers from the Foundation for Applied Molecular Evolution have announced a new finding, showing that ribonucleic acid (RNA) can spontaneously form on basalt lava glass. RNA is a molecule, similar … Read more

NASA scientists find evidence that Life on Earth may have come from an asteroid

NASA scientists along with researchers from Japan have found a crucial link between life on Earth and asteroids while studying the five components of DNA and RNA. Find out what the study has revealed. NASA: There has always been that one question in the corner of our mind, how did life begin on Earth? It … Read more
