The cosmic microwave background is a wall of light—here’s how we might see beyond it

by quasarn01 | Oct 28, 2025 | Astronomy

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of galaxies and supermassive black holes. But all of it is invisible...

Spectral biosignatures of airborne microbes in planetary atmospheres

by quasarn01 | Oct 28, 2025 | Astronomy

Could scientists find life in the clouds of exoplanet atmospheres? This is what a manuscripton the arXiv preprint server hopes to address as a team of researchers investigate how the biosignatures of microbes could be identified in exoplanet atmospheres and clouds. Go...
