Not everyone accepts the scientific consensus; some even make careers out of challenging it. But only a select few do it the right way.
Side-by-side images of a nebula in space, showing colorful, wispy gas and dust shells surrounding a bright central region with numerous stars in the background.
Resembling a cosmic brain, the Exposed Cranium Nebula instead shows a dying, massive star, as JWST reveals. Its fate remains uncertain.

Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.

Most failures trace back to people problems. If you want long-term success, start with your team. Here’s how to build teams that will actually last and make an impact.

Brian Cox examines why, despite billions of stars and trillions of planets, we have found no evidence of other intelligent life.
No civilization, no matter how successful, can last forever. What does the non-detection of intelligent aliens mean for our own longevity?
A person with purple hands holds a phone displaying text messages that read, "OMG then what happened??.
Throughout history, the ability to tell increasingly believable stories has become available to more people. Kevin Ashton says that’s a blessing and a curse.
A view of a star-filled night sky with numerous bright stars and distant galaxies, including Hubble-dark galaxy formations, scattered across a dark background.
The discovery of CDG-2, a galaxy that's more than 99.9% dark matter, could reveal a new population of ultra-faint galaxies. But is it real?

When people born blind gain sight, the hardest part isn’t opening their eyes — it’s teaching the brain how to see.

Thanks to modern tech, Earth is now considered a ‘detectable’ planet. Astrophysicist Sara Seager explains how this idea can lead us to discovering life elsewhere in our universe.
Voyager
No human has ever left the Solar System, and only six already-launched spacecraft will ever exit it. Will Voyager 1 remain the most distant?
A man in glasses and a suit jacket sits indoors, gesturing with his right hand. Exposed brick walls, a window, and a lamp are visible in the background.

"The production of the silicon wafers that are used in the chip manufacturing process requires extraordinary levels of purity."
black hole
Quantum entanglement links information between particles across space and time. So what happens when one of them falls into a black hole?
A radio telescope observes a distant galaxy; insets show a magnified view of the galaxy—home to the most distant laser—and a spectral graph. Illustration attributed to IDIA.
Forget about the terawatt lasers we're making on Earth. The Universe makes natural ones thousands of times more powerful than the Sun.
hubble tension
Even space and time are relative in Einstein's universe. That means our old notions of "where" and "when" no longer apply on cosmic scales.
