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 ...

Q&A: What if we don't find any life on exoplanets?

Scientists are currently planning two major space missions to search for life in space: NASA's Project HWO and Project LIFE, led by ETH Zurich. If one of these missions were to discover life on an exoplanet, i.e., a planet ...

Scientists uncover why carbon-rich meteorites rarely reach Earth

An international team of researchers may have answered one of space science's long-running questions—and it could change our understanding of how life began. Carbon-rich asteroids are abundant in space yet make up less than ...

Q&A: How to (theoretically) spot an alien

Are we alone in the universe? The answer to one of humanity's biggest questions is complicated by a basic reality: If there is life on other worlds, it may not look familiar. A sample of rocks from Mars or another planet ...

The search for biosignatures in Enceladus' plumes

What kind of mission would be best suited to sample the plumes of Saturn's ocean world, Enceladus, to determine if this intriguing world has the ingredients to harbor life? This is what a recent study presented at the 56th ...
