Exoplanets could be hiding their atmospheres
Most of the exoplanets we've discovered orbit red dwarf stars. This isn't because red dwarfs are somehow special, simply that they are common. About 75% of the stars in the Milky Way are red dwarfs, so you would expect red ...

Life might thrive on the surface of Earth for an extra billion years
The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to ...

Plants could still grow well under alien skies
Photosynthesis changed Earth in powerful ways. When photosynthetic organisms appeared, it led to the Great Oxygenation Event. That allowed multicellular life to evolve and resulted in the ozone layer. Life could venture onto ...

Scientists scan TRAPPIST-1 for technosignatures
If you are going to look for intelligent life beyond Earth, there are few better candidates than the TRAPPIST-1 star system. It isn't a perfect choice. Red dwarf stars like TRAPPIST-1 are notorious for emitting flares and ...

Detailed model suggests organic matter on Mars was formed from atmospheric formaldehyde
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually life. In their quest to answer the burning ...

Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the ...
Projecting what Earth will look like 1,000 years from now could assist in search for advanced civilizations
The Search for Extraterrestrial Intelligence (SETI) is regularly plagued by the fact that humanity has a very limited perspective on civilization and the nature of intelligence itself. When it comes right down to it, the ...

Could comets have delivered the building blocks of life to ocean worlds like Europa, Enceladus and Titan?
Throughout Earth's history, the planet's surface has been regularly impacted by comets, meteors, and the occasional large asteroid. While these events were often destructive, sometimes to the point of triggering a mass extinction, ...

Life on alien planets probably wouldn't experience day and night—here's how that may change evolution
Do aliens sleep? You may take sleep for granted, but research suggests many planets that could evolve life don't have a day and night cycle. It's hard to imagine, but there are organisms living in Earth's lightless habitats, ...

In the hunt for alien life, is man truly 'the measure of all things?'
Enrico Fermi's lunchtime question at wartime Los Alamos, "Where is everybody?" has been both a gift and a problem to scientists ever since. Known as "Fermi's Paradox," it simply asks, why, since life on Earth is ubiquitous ...
Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's ...

Rocks collected on Mars hold key to water and perhaps life on the planet: Researchers urge bringing them back to Earth
Over the course of nearly five months in 2022, NASA's Perseverance rover collected rock samples from Mars that could rewrite the history of water on the red planet and even contain evidence for past life on Mars.
