Breakthrough Listen Publishes Most Comprehensive and Sensitive Search for Radio Technosignatures Ever Performed

Breakthrough Listen - the astronomical program searching for signs of intelligent life in the Universe - has submitted two publications to leading astrophysics journals, describing the analysis of its first three years of radio observations and the availability of a petabyte of radio and optical telescope data.

Impact of Stellar Superflares on Planetary Habitability

Impact of Stellar Superflares on Planetary Habitability

High-energy radiation caused by exoplanetary space weather events from planet-hosting stars can play a crucial role in conditions promoting or destroying habitability in addition to the conventional factors.

Can We Detect Aurora in Exoplanets Orbiting M dwarfs?

Can We Detect Aurora in Exoplanets Orbiting M dwarfs?

New instruments and telescopes, such as SPIRou, CARMENES and TESS, will increase manyfold the number of known planets orbiting M dwarfs.

Deep-ocean Vents Fuel Massive Phytoplankton Blooms

Deep-ocean Vents Fuel Massive Phytoplankton Blooms

Researchers at Stanford University have found an aquatic highway that releases nutrients from within the Earth and ferries them up to surface waters off the coast of Antarctica. There the nutrients stimulate explosive growth of microscopic ocean algae.

Germs and Geothermals

Germs and Geothermals

The collaboration is looking at a group of organisms called 'extremophiles'--organisms that live in extremely hot or extremely cold environments unsuited to human habitation.

Effects of a Binary Companion Star on Habitability of Tidally Locked Planets around an M-type Host Star

Effects of a Binary Companion Star on Habitability of Tidally Locked Planets around an M-type Host Star

Planets in the "Habitable Zones" around M-type stars are important targets for characterization in future observations.

Theoretical Study of Interstellar Heterocyclic Molecules

Theoretical Study of Interstellar Heterocyclic Molecules

Because of their importance in biological systems, in our understanding of the solar system and in other applications, seven heterocycles; furan, imidazole, pyridine, pyrimidine, pyrrole, quinoline and isoquinoline have been astronomically searched for in different molecular clouds.

Organic Carbon Hides In Sediments Keeping Oxygen In Earth's Atmosphere

A new study from researchers at the Woods Hole Oceanographic Institution (WHOI) and Harvard University may help settle a long-standing question--how small amounts of organic carbon become locked away in rock and sediments, preventing it from decomposing.
