Between eternal night and day, the faces of two cousins of Earth

An international team including the University of Bern (UNIBE) and the University of Geneva (UNIGE), members of the National Center of Competence in Research PlanetS, has succeeded in mapping the climate of rocky exoplanets ...

How plants could betray themselves across the galaxy

Here's a thought experiment. Imagine looking at Earth from a distant star system, armed with a powerful telescope capable of capturing its reflected light. Could you tell the planet was alive? The answer, remarkably, might ...

New Henrietta spectrograph to probe alien atmospheres

Finding life beyond our solar system goes beyond measuring an exoplanet's size, as rocky, Earth-sized worlds might not have the conditions for life as we know it. While exoplanets can be directly imaged by blocking their ...

Human sperm may get lost in space

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational abilities of sperm are negatively impacted by a lack of gravity. Researchers at the University's Robinson ...

How hidden stars shape our search for technosignatures

How can star populations help astronomers re-evaluate the search for intelligent extraterrestrial life, also called technosignatures? This is what a study released on the preprint server arXiv, hopes to address as a team ...

Why being in the 'right place' isn't enough for life

A planet's habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable worlds beyond our solar system have focused exclusively on their position in the "Goldilocks Zone" of ...

What seven decades of hunting for aliens tells us

Since the 1950s, humanity has been searching for extraterrestrial life with increasingly sophisticated tools. But after decades of space probes, meteorite analysis, radio telescopes, and UFO investigations, what have we actually ...

Meteorite samples are time capsules from the early solar system

When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our ...

Life is just matter with meaning

What are the physics of life? That is more than just a philosophical question—it has practical implications for our search for life elsewhere in the galaxy. We know what Earth life looks like, on a number of levels, but finding ...
