Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]

What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
The history of the Universe is forever imprinted in our own bodies. We can learn a lot about the history of the Universe just by looking at each of our own […]
We all share atoms with every person, living or dead, on Earth. There’s more in common among us than you might think. When you eat food, drink liquids, or even breathe […]
Almost certainly not. Here’s the science of why. The Universe, as we know it, simply doesn’t add up. On the one hand, we can look out on a cosmic scale and […]
Don’t miss the summer’s greatest natural sights of all. Some of the natural highlights of our night sky are easy to overlook. Every year, you’ll hear about some of the brightest, […]
NASA’s New Horizons is the most distant technologically advanced observatory ever. And that makes all the difference. When you look at an object that’s very distant from you, how well […]
After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
The age of the Universe is only 13.8 billion years, but we know that protons survive much longer. Here’s how. Since the discovery of radioactivity in the 19th century, humanity has […]
Our Universe is 13.8 billion years old, and our Sun formed about 2/3rds of the way through. Here’s what came before it. When it comes to the great cosmic question of […]
The top of Mauna Kea is the ideal physical site for this new, ready-to-be-built telescope. But that’s far from the only concern. For many years, astronomers have looked forward to a […]
When you’re trying to peel back the veil obscuring the fundamental nature of matter, you have to look absolutely everywhere. Sometimes, the solution to a puzzle you’ve been stymied by […]
There’s no such thing as a theory that’s too beautiful to be wrong, if it doesn’t agree with experiment. The history of physics is filled with great ideas that you’ve […]
If dark energy were stronger or weaker, everything would be pretty much the same. And that’s a puzzle. After the Big Bang, the Universe was full of matter and radiation. It […]
In the aftermath of everything we’ve learned about what’s in the Universe, we can make much better estimates of how many alien civilizations are out there. In 1961, scientist Frank Drake […]
There have been a lot of public advocates from the “no dark matter” camp, getting lots of popular attention. But the Universe still needs dark matter. Here’s why. If you took […]
If nature makes equal amounts of matter and antimatter, how are we here? When you look out at the vastness of the Universe, at the planets, stars, galaxies, and all there […]
It isn’t the rapture or some crazy prophesy, but science, that tells us when and how the end will come. “The surface of the Earth is the shore of the cosmic […]
No other object this large has come so close to Earth in millions of years. In the 5th millennium, we might suffer the consequences. “Honestly, if you’re given the choice […]
On August 21st, 2017, a total eclipse will hit 14 states. Here’s your guide to everything you need to know. “…and the Sun has perished out of heaven, and an […]
How to stay safe and prepare yourself for the show of a lifetime! “Nations, like stars, are entitled to eclipse. All is well, provided the light returns and the eclipse […]
From a Universe that went no bigger than our Milky Way to the trillions of galaxies in our expanding Universe, our knowledge increased one step at a time. “Gamow was fantastic […]
A live-blog event happened a week ago, but you can catch the entire thing anew here, right now! “We have never observed infinity in nature. Whenever you have infinities in […]
We haven’t found the truly “first” ones yet, but we’re not just on our way; we’re almost there. “For the first time we can learn about individual stars from near the […]
You may have heard of Laniakea, but don’t count on it being real. “It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest […]
Could the Universe have been born completely uniform and still given rise to us? “First, you should check out my house. It’s, like, kinda lame, but way less lame than, like, […]
That’s not how probability works. Or asteroids, for that matter. “Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, […]
But not every location was created equal. “Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun. […]
