Astronomers have mapped out the chemicals inside of planetary nurseries in extraordinary detail.

Exoplanets orbiting M-dwarfs within habitable zones are exposed to stellar environments more extreme than that terrestrial planets experience in our Solar System, which can significantly impact the atmospheres of the exoplanets and affect their habitability and sustainability.

Small organic molecules, such as C2H, HCN, and H2CO, are tracers of the C, N, and O budget in protoplanetary disks.

Interstellar signals might be intermittent for many reasons, such as targeted sequential transmissions, or isotropic broadcasts that are not on continuously, or many other reasons.

We investigate modons on tidally synchronised extrasolar planets. Modons are highly dynamic, coherent flow structures composed of a pair of storms with opposite signs of vorticity.

The precursors to larger, biologically-relevant molecules are detected throughout interstellar space, but determining the presence and properties of these molecules during planet formation requires observations of protoplanetary disks at high angular resolution and sensitivity

NASA announces the award of 10 grants or cooperative agreements for exciting new Space Biology research that will advance NASA's understanding of how living systems respond, acclimate, and adapt to the space environment in support of human space exploration.

Many scientists consider the "Cambrian explosion" -- which occurred about 530-540 million years ago -- as the first major appearance of many of the world's animal groups in the fossil record.

Researchers supported in part by the NASA Astrobiology Program have experimentally tested a method that could aid in the search for life... including life as we don't know it.

Despite their importance for determining the evolution of the Earth's atmosphere and surface conditions, the evolutionary histories of the Earth's atmospheric CO2 abundance during the Archean eon and the Sun's activity are poorly constrained.

A profound shift in the study of cosmology came with the discovery of thousands of exoplanets and the possibility of the existence of billions of them in our Galaxy. The biggest goal in these searches is whether there are other life-harbouring planets.

The COgITOR project is aimed at formulating a new concept of artificial cybernetic system, taking its name from Descartes's maxim "Cogito, ergo sum" and drawing inspiration from the new frontier of robotics that aims to reduce, if not completely cancel, system rigidity.

For centuries, humans have mined materials to build the tools we use every day, from batteries and cell phones to airplanes and refrigerators. While the process of obtaining these important minerals used to rely entirely on heavy machinery, fire, and human labor, scientists have learned how to harness the natural power of microbes to do some of the work.

A hair-like protein hidden inside bacteria serves as a sort of on-off switch for nature's "electric grid," a global web of bacteria-generated nanowires that permeates all oxygen-less soil and deep ocean beds, Yale researchers report in the journal Nature.
