The longest organic molecules identified to date on Mars have recently been detected by scientists from the CNRS, together with their colleagues from France, the U.S., Mexico, and Spain. These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity.

The lack of geological activity and the cold, arid climate on Mars have helped preserve this invaluable organic matter in a clay-rich sample for the past 3.7 billion years. It therefore dates from the period during which life first emerged on Earth. These findings are due to be published on March 24, 2025, in the Proceedings of the National Academy of Sciences.

The discovery was made using SAM, one of the inst...

The Dragonfly telescope is undergoing a metamorphosis. For the past decade, the Dragonfly Telephoto Array — designed by Yale’s Pieter van Dokkum and the University of Toronto’s Roberto Abraham and located in New Mexico — has conducted groundbreaking science by detecting faint starlight within dimly lit parts of the night sky. The telescope uses clusters of telephoto lenses to create images, much the way a dragonfly’s eyes gather visual data.

The telescope has spotted previously unseen “fluffy” galaxies, diffuse dwarf galaxies, and galaxies with little or no dark m...

Dragonfly, a New Frontiers-class mission concept that the Johns Hopkins Applied Physics Laboratory has proposed to NASA, would use an instrumented, radioisotope-powered, dual-quadcopter to explore potential habitable sites where life could be developed on Saturn’s largest moon, Titan. The moon is one of a number of “ocean worlds” in our solar system that hold the ingredients for life, and is known to be covered with rich organic material that is undergoing chemical processes that might be similar to those on early Earth, before life developed.

Titan has diverse, carbon-rich chemistry on a surface dominated by water ice...
