Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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 […]
Never draw a conclusion, no matter how ‘obvious,’ without doing the experiment first. We all love our most cherished ideas about how the world and the Universe works. Our conception […]
The Universe was born matter-antimatter symmetric. Here’s what happened when the last of our antimatter disappeared. Things happen fast in the earliest stages of the Universe. In the first 25 […]
In all the years of NASA, we’ve never touched the Sun before. Here’s why it’s so hard. This past weekend, NASA successfully launched the Parker Solar Probe: the first spacecraft that […]
In General Relativity, even space and time themselves aren’t what they seem. Gravity might have been the first fundamental force ever discovered, but in many ways, it remains the least-well understood. […]
The ices and rock aren’t green, and neither are the tails. So where does a comet’s green color come from? Every so often, with extreme regularity, comets will plunge from beyond […]
If the Breakthrough Starshot initiative, promoted by Stephen Hawking, works exactly as planned, it could lead to disaster. Imagine yourself on a world not so different from Earth, orbiting a […]
NASA’s Cassini spacecraft taught us more than we ever imagined about Saturn. Could we do something similar for Uranus and Neptune? From where we are in the Solar System, looking out […]
Three great things all align this August, making the Perseids a can’t-miss show. Here’s how to take advantage. When it comes to meteor showers, we have these dazzling pictures in […]
Mars will never look as big as the full Moon. But it isn’t even the biggest planet. From humanity’s perspective, the Sun and Moon always dominate Earth’s skies. The Moon and […]
It wasn’t just the Milky Way and Andromeda two billion years ago. Here in the Local Group, our two largest galaxies dominate: Andromeda and the Milky Way. Our Local Group of […]
Did the Universe begin at time t=0? Did space and time emerge from that? The Universe, today, is expanding and cooling, as the volume of the Universe increases while the number […]
If our current laws of physics can’t predict what will happen, even probabilistically, we need something new. There are two theories we have that explain all the particles and their […]
Our best physical theories predict that a multiverse exists. But if we can’t test it, is it really scientific? The Universe is all there ever was, all there is, and […]
