Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
California’s Bobcat Fire has reached Mount Wilson Observatory’s doorstep. 100 years ago, our understanding of the Universe was very different from what it is today. Einstein’s General Relativity, our theory […]
It will take a national effort to get it done. Here’s how. Over the past six months — a full half of a year — the United States has suffered more deaths and illnesses due […]
Just because you have “star” in your name doesn’t mean you are one. When we think about the objects in our Universe, they fall into two categories: self-luminous objects, like stars, […]
Have any of the stars we can see burned themselves out completely? When we look out across the Universe, we’re also peering back in time. In the early 21st-century, we’ve […]
Black holes are the darkest objects of all. But are they made of dark matter? When it comes to the Universe, few objects are more compelling, fascinating, or extreme than black […]
When two black holes that shouldn’t exist are seen merging, physics has some explaining to do. After years of searching for gravitational waves, it finally happened: LIGO bagged the biggest one […]
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 […]
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
The view is different for each of us, but this perspective unites us all. From anywhere on Earth, the entire sky rotates a full 360° every 24 hours. From Earth, star […]
If they have mass, then why don’t we see any slow-moving ones? For decades, the neutrino was among the most puzzling and elusive of cosmic particles. It took more than […]
The largest moon around our last planet didn’t originate with Neptune. When it comes to the moons of our Solar System, there’s only one planet that doesn’t fit in with our […]
NASA’s James Webb Space Telescope will truly usher in a new era of astronomy. If you want to find the very first galaxy of all, you have to understand not […]
The pendulum didn’t tick right when they brought it here: the start of a fascinating story. For nearly three full centuries, the most accurate way that humanity kept track of […]
There was a time in the Universe before we formed stars. Here’s how we’re exploring it. When we look out at the Universe today, we see that it’s full of […]
Quantum physics just keeps getting weirder, even as it gets more fascinating. “Is it a wave or is it a particle?” Never has such a simple question had such a […]
The Big Bang started it all. And then we realized there was more. Of all the questions humanity has ever pondered, perhaps the most profound is, “where did all of this […]
It likely isn’t the rare occurrence we once thought it was. In our Solar System, there’s one overwhelming source of mass that all the planets orbit around: our Sun. Each planet […]
If there are cracks in Einstein’s theory, this is how to find them. Is Einstein’s most powerful theory, General Relativity, always correct? Or will there come a point where it breaks […]
It’s fundamentally different from space. Here’s how. Here’s a question that most of us have been asked at some point in our lives, “what’s the shortest distance between two points?” By […]
When one group says “A” and another group says “B,” consider that everyone might be wrong. One of the biggest enemies of scientific truth is the setup of a false dichotomy. […]
