Nautilus array to track missing exoplanet atmospheres

Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can't be directly imaged yet, so astronomers must get creative in how they search ...

The rise of space AI might explain the Fermi paradox

Artificial intelligence (AI) is continuing to have a disruptive impact on ever more parts of humanity. But what does it mean in the long run? A new paper, available as a preprint on arXiv from Austrian researcher Sergey Ivliev, ...

Organic carbon detected in Bright Angel rock formation on Mars

In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously ...

If aliens landed on Earth tomorrow, what would they eat?

With the release of "Disclosure Day," Steven Spielberg's new film about aliens, a question as old as science fiction itself resurfaces: If aliens were to arrive on Earth, would they come to conquer us, to study us ... or ...

Texas wine grapes launch to space for research mission

Researchers from Texas A&M AgriLife are sending hundreds of grape seeds to the International Space Station, where the seeds will spend approximately six months exposed to cosmic radiation before returning to Earth for planting ...

Introducing the Interplanetary Habitable Zone

Anyone familiar with the search for alien life will have heard of the "Goldilocks Zone" around a star. This is defined as the orbital band where the temperature is just right for liquid water to pool on a rocky planet's surface—a ...

Scientists successfully harvest chickpeas from 'moon dirt'

As the U.S. plans to return to the moon with the upcoming Artemis II mission, a question endures: What will future lunar explorers eat? According to new research from The University of Texas at Austin, the answer might be ...

Life forms can planet hop on asteroid debris—and survive

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily ...

How long do civilizations last?

It is one of the most famous questions in science, and it was asked, as legend has it, over lunch. Enrico Fermi, the physicist who helped build the first nuclear reactor and whose name graces a unit of length so small it ...
