The Solar System isn't a vortex, but rather the sum of all our great cosmic motions. Here's how we move through space.

The Crab Nebula goes back to 1054, opening a window into our cosmic past. On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation. A ‘guest star’ […]
Even 13.8 billion years after the Big Bang, we can reconstruct the first 3 minutes. About 100 years ago, we began to truly understand the nature of the Universe for the […]
If we want our conclusions to be meaningful, our data had better be robust. When it comes to the Universe, there’s a whole lot that doesn’t add up. All the matter […]
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 […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
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 […]
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 […]
We just found the first one within 1,000 light-years of us. But there’s probably one much, much closer. For a long time, black holes were known to exist only in the […]
In 2006, the IAU demoted Pluto. Here’s what we know today. In 2006, the last planet in our Solar System suffered an unforgettable insult, as Pluto — known for generations as our ninth […]
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 […]
Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]
One look at the uncertainties and the assumptions changes the story tremendously. Is there intelligent life out there in the Milky Way beyond our own Solar System? If so, how […]
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 […]
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, […]
Scientific surprises are often how science advances. But more often than not, they’re just bad science. When you’re a scientist, getting an unexpected result can be a double-edged sword. The best […]
The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]
"I share this honor with ancestors and teachers who inspired in me a love of poetry," the 68-year-old poet said.
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 […]
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 […]
As soon as you start thinking about energy and gravity, you’ll realize the need to go beyond it. When it comes to a science like physics, theoretical expectations must always be […]
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 […]
It’s true that we have a thermodynamic arrow of time, and entropy always increases. But that can’t explain what we perceive. One of the enormous conceptual ideas that came along […]
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 […]
Elite organizations tend to get conspiracy theorists going.
The ICARUS Initiative aims to track migratory animals from space using special transmitters and antennae. The data retrieved from the project will help us conserve biodiversity but has the potential to promote human well-being and prosperity, too.
In 2015, the ultra-distant galaxy CR7 was measured to have hydrogen and helium, but no carbon or oxygen. With new ALMA observations, there’s carbon after all. As brilliant as our Universe’s […]
We see matter, but not antimatter, in our Universe. Could black holes be the answer? One of the greatest cosmic puzzles in our entire Universe is why there’s so much more […]
We always assume that dark matter is particle-based, and we just need to find which particle it is. But what if it isn’t so? Everything we’ve ever detected in the Universe, […]
