Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
If you thought that diamonds were the hardest things of all, this will have you thinking again. Carbon is one of the most fascinating elements in all of nature, with chemical […]
At the core of the largest star-forming region of the Local Group sits the biggest star we know of. Mass is the single most important astronomical property in determining the lives […]
Two independent techniques give precise but incompatible answers. Here’s how to resolve it. If you didn’t know anything about the Universe beyond our own galaxy, there are two different pathways you […]
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
Has the mystery really been solved? Doubtful. The real science goes much deeper. For perhaps the last year or so, a small galaxy located not too far away has captivated the […]
If we could see in three dimensions instead of two, we’d never have thought otherwise. Perhaps the most famous sight of a dying star is the Ring Nebula, discovered in […]
13.8 billion years isn’t close to enough time, but if we wait long enough, even our Sun will become one. The Big Bang happened approximately 13.8 billion years ago, and it […]
The solar eclipse of May 29, 1919, was the nail in the coffin of a Newtonian Universe. On May 29, 1919, the world changed forever. For hundreds of years, Isaac […]
Everything on Earth is made of atoms and their building blocks. Without this one rule, they’d never make anything interesting. Take a look around you at everything on Earth. If […]
Imagine how different our understanding of the Universe would be if we saw nothing beyond the Milky Way. Our corner of the Universe was gifted with a plethora of bright, nearby […]
Even the best science imaginable has its limits. In terms of ambition, it’s hard to ask for more than to know absolutely everything there is to know about the Universe. That’s […]
A 1060-hour amateur exposure of a nearby galaxy does what even Hubble couldn’t do. The Universe is full of astronomical wonders, but it’s up to humanity to observe and analyze them. […]
Neither one reflects the other; they’re both blue for entirely different reasons. If you’ve ever been curious about the world you live in, you’ve probably wondered why the sky is […]
The cosmic story of us wasn’t inevitable, but the culmination of many chance events. By the time our planet was four billion years old, the rise of large plants and animals […]
The two planets most suited for habitability had very different fates. At last, scientists know why. Imagine the early days of our Solar System, going back billions of years. The Sun […]
Some claim that inflation isn’t science, but it sure has made some incredibly successful scientific predictions. So, you want to know how the Universe began? You’re not alone. Every other […]
Depending on how you measure it, there are two different answers that could be right. If you want to see what’s out there in the Universe, you first have to be […]
The world’s greatest observatory can go no further with its current instrument set. The Hubble Space Telescope has provided humanity with our deepest views of the Universe ever. It has […]
Dark matter, dark energy, inflation and the Big Bang are real, and the alternatives all fail spectacularly. If you keep up with the latest science news, you’re probably familiar with […]
The small step that one man took would never have happened without this narrow escape. On July 20, 1969, history was made as humanity set foot on the Moon for the […]
