Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
If the Sun is 93 million miles away, why does sunlight filtering through the clouds or the trees spread out? Rays of sunshine are one of those natural sights that leave […]
We can’t help but wonder if it’s habitable, or even inhabited, but the evidence isn’t there for it. Every star that fills the night sky carries along with it one of […]
If all you see is low-energy light in a myriad of directions, you can’t be sure. But this light comes from the Big Bang. There are a lot of things that […]
These three reasons are why there’s no getting around the fact that astronomy needs the James Webb Space Telescope. Even the most powerful telescope in history, the Hubble Space Telescope, […]
LIGO’s enormous arms contract and expand as gravitational waves pass through them. But, puzzlingly, so does the light within them. For the past three years, humanity has known a new kind […]
The nightmare scenario of no new particles or interactions at the LHC is coming true. And it might be our own fault. Over at the Large Hadron Collider, protons simultaneously circle […]
Shortly after the Big Bang, the Universe became completely dark. The first stars, when they ignited, changed everything. For perhaps 100 million years, the Universe was devoid of stars. The […]
An Oxford physicist tries to cast doubt on dark energy, but the data says otherwise. It was a mere 20 years ago that our picture of the Universe got a […]
Of all the experiments performed and measurements made involving fundamental particles, none has ever violated the Standard Model. Until now. If there’s one thing you can count on physicists for, it’s […]
Our biases, preferences, and ideas of simplicity and elegance can get in the way. Here’s a scientific way to cut through them all. What are the rules governing reality? If you […]
Not everyone is satisfied with the Big Bang. But every alternative is a disastrous failure. It’s treated as though it’s an unassailable scientific truth: 13.8 billion years ago, the Universe […]
Some wildfires will always be unavoidable. But nature, thankfully, recovers relatively quickly. The past few years have brought some devastating wildfires to large parts of the American west. A wildfire […]
Dark matter is our leading theory for a reason. New, detailed studies of the smallest galaxies could kill off the most studied alternative. When you look out at the Universe, […]
One of the most popular viral videos about space is dead wrong. But it gives us a chance to learn something incredible. There are a lot of moving parts to […]
It took hundreds of thousands of years to make atoms for the first time. If things were just a little different, it could have taken an eternity. When it comes […]
Stars don’t stay the same throughout their life, and the Sun is no exception. Here’s what’s going on. Here on Earth, the ingredients for life to survive, thrive, evolve, and sustain […]
The most massive star in the known Universe is 260 times as heavy as our Sun. But viewing the early Universe will shatter that record. Place enough mass together in one […]
Our Universe may not be all there is, was, or ever will be, after all. There’s been a lot of speculative ideas put forth about the Multiverse, and I dare say […]
Before there were humans, planets, or even stars and galaxies, we had to make the first elements. Here’s how they happened. From the first moments of Big Bang to the […]
Different measurements of the Universe’s rate of expansion give inconsistent results. But this simple solution could fix everything. In 1915, Einstein’s theory of General Relativity gave us a brand new […]
