Astronomers have detected a stinky gas on Venus called phosphine, and weirdly enough, it could be a sign of alien life in the planet’s clouds. It’s still too early to say for sure that Venus hosts life forms, but the discovery opens up a lot of questions about what’s happening on Earth’s neighbor.

I’ve felt this might be true for many years. There’s obviously nothing inherently biological about neural networks. It could even explain the development of intelligent life when so many things work against that development — the universe is driven to try to create intelligence — a form of “intelligent design.”

We live inside a neural network, he says, not a simulation — “but we might never know the difference.”

A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky known to include at least 10 million stars.

Astronomers used the Murchison Widefield Array (MWA) telescope to explore hundreds of times more broadly than any previous search for extraterrestrial life.

Earlier this week, Elon Musk said there’s a “good chance” settlers in the first Mars missions will die. And while that’s easy to imagine, he and others are working hard to plan and minimize the risk of death by hardship or accident. In fact, the goal is to have people comfortably die on Mars after a long life of work and play that, we hope, looks at least a little like life on Earth.

🌌 You love our badass universe. So do we. Let’s explore it together.

When searching for signs of life in the Universe, we tend to look for very specific things, based on what we know: a planet like Earth, in orbit around a star, and at a distance that allows liquid surface water. But there could, conceivably, be other forms of life out there that look like nothing that we have ever imagined before.

Just as we have extremophiles here on Earth — organisms that live in the most extreme and seemingly inhospitable environments the planet has to offer — so too could there be extremophiles out there in the wider Universe.

For instance, species that can form, evolve, and thrive in the interiors of stars. According to new research by physicists Luis Anchordoqui and Eugene Chudnovsky of The City University of New York, such a thing is indeed — hypothetically, at least — possible.

A comprehensive review of life as we know it—and may not know it.

In a new paper just published in the journal Universe, Louis Irwin and I attempt to sum up scientists’ current understanding of life “as we know it,” and speculate how life may look and function on alien planets and moons. That includes potential biospheres very different from our own, such as a rocky planet with an ice-covered global ocean. Or it might be a barren planet devoid of surface liquids, or a frigid world with abundant liquid hydrocarbons. It could even be a rogue planet with no “host” star, a tidally locked planet, or a so-called Super-Earth. Maybe the biosphere exists only in the planet’s atmosphere.
