You can lead an overconfident chatbot to expert knowledge, but can it actually learn and assimilate new information?
2022 was a year full of scientific discoveries and the dawn of the JWST. But Hubble's still going after 32 years. Here's the amazing proof!
As far as we know, it's only happened once to one unlucky person in Oklahoma.
Leaving Hubble in the dust, JWST has officially seen a galaxy from just 320 million years after the Big Bang: at just 2.3% its current age.
The very dust that blocks our view of the distant, luminous objects in the Universe is responsible for our entire existence.
The most common element in the Universe, vital for forming new stars, is hydrogen. But there's a finite amount of it; what if we run out?
We thought the Big Bang started it all. Then we realized that something else came before, and it erased everything that existed prior.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer's suggestive simulation.
Perhaps wormholes will no longer be relegated to the realm of science fiction.
A Carrington-magnitude event would kill millions, and cause trillions of dollars in damage. Sadly, it isn't even the worst-case scenario.
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
The answer to this question is key to understanding why anything exists.
We'll never be able to extract any information about what's inside a black hole's event horizon. Here's why a singularity is inevitable.
By studying the dwarf galaxy Wolf-Lundmark-Melotte ~3 million light-years away, JWST reveals the Universe's star-forming history firsthand.
We confidently state that the Universe is known to be 13.8 billion years old, with an uncertainty of just 1%. Here's how we know.
Every time our Universe cools below a critical threshold, we fall out of equilibrium. That's the best thing that ever happened to us.
The strongest tests of curved space are only possible around the lowest-mass black holes of all. Their small event horizons are the key.
The Universe is 13.8 billion years old, going back to the hot Big Bang. But was that truly the beginning, and is that truly its age?
It is humanity's biggest step yet into the Solar System.
There's the textbook answer, then there's the real answer.
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
We cannot afford to dream about living on other worlds while we continue to destroy ours.
From astrobiology to geology, a Moon base could serve as a laboratory unlike anything on Earth.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
It's rare that one single image packs so much beauty and science simultaneously. This Hubble view of a nearby star-forming region has both.
Supermassive black holes at the centers of galaxies gobble up whatever matter ventures too close, becoming active. Here's how they work.
We're used to scientists telling us about the math and physics behind astronomical events. But what does studying space make us feel?
You are trapped in time. You never live in the world as it is but only as you experience it as it was.
