All stars shine due to an internal source of energy. Usually, it's nuclear fusion: converting mass into energy. What makes them most bright?

"There is interesting ethical questions about how we should actually conduct ourselves in [a space colonization] exploration phase."

You don't need to be a scientist or a philosopher for facts, reality, and the truth to matter. The alternative is simply known as bullshit.

In this preview from "The Saucerian," author Gabriel Mckee explains how the combination of fantastical stories and obscure bureaucracy launched the “space age of the imagination.”

As we shape our future we should ask: Which interpretations of classic sci-fi fables hold sway with today’s powerful tech leaders?

A Cambridge-based team claims to find molecules on an exoplanet that are only produced by life on Earth. Don't fall for the unfounded hype.

According to Stephen Hawking, spontaneously emitted radiation should cause all black holes to decay. But we've never seen it: not even once.

In all the known Universe, Earth is the only planet known to have native life. What should guide us in expanding humanity beyond our world?

If an asteroid hadn't killed off the dinosaurs, humans would almost certainly have never walked the Earth.

After drastic cuts to the NIH, the FDA, the NSF, and the DOE, NASA science faces down its smallest budget ever. All of society will suffer.

Perhaps no existential question looms larger than that of our ultimate cosmic origins. At long last, science has provided the answers.

From religious iconography to modern mysticism, the human aura has been a subject of fascination across centuries and cultures.

The Hubble Space Telescope, launched in 1990, was originally seen as a colossal mistake. This one image, taken in 1995, changed everything.

Surprisingly, multimodal large language models struggle to read time on analog clocks.

"Asking the question of, "Where did the entire universe come from?" is no longer a question for poets and theologians and philosophers. This is a question for scientists, and we have some amazing scientific answers to this question."

In theory, scientists could've produced a deadly virus that accidentally infected lab workers. In practice, we know that didn't happen.

"What would a totalitarian society that is not well disposed to our own do if it had God-like power? We don't wanna find out."

Planets can create nuclear power on their own, naturally, without any intelligence or technology. Earth already did: 1.7 billion years ago.

The most famous Hubble images show glittering stars and galaxies amidst the black backdrop of space. But more was captured than we realized.
