Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Congratulations to Penrose, Ghez and Genzel, and to black hole enthusiasts everywhere. On October 6, 2020, the Nobel Prize in Physics was awarded towards research in black holes. 50% of […]
We’ve argued over ideology for far too long. It’s time to pick a better route to prosperity. In every civilized society around the world, there’s a trade-off that must be […]
At its biggest for the next 15 years, it’s still much smaller than the Moon. On October 6, 2020, Mars makes its closest approach to Earth until 2035. Earth orbits in […]
Why does dark matter, if it doesn’t dissipate energy, become gravitationally bound at all? One of the most puzzling components of the Universe has to be dark matter. Although we have […]
The anthropic principle has some fascinating scientific uses. And abuses, too. For thousands of years, humans have pondered the meaning of our existence. From philosophers who debated whether their minds could […]
Even in the most exotic scenario imaginable, they still can’t remain stable in the Earth’s interior. It’s well known among scientists that if you submit even the most nonsensical paper […]
The Twin Jet nebula, shown here, is a stunning example of a bipolar preplanetary nebula. At the center, a dying star is in the final stages of life where it […]
We just found a system that we can’t explain. Here’s what’s going on. One of the most fascinating facts about the Universe is that there’s so much of it out there. […]
Could this finally be the clue we’ve hoped for in uncovering the truth about dark matter? In the physical sciences, theory and observation are supposed to work hand-in-hand. Theorists work out […]
If we waited long enough, would even protons themselves decay? There are certain things in the Universe that, if you leave them alone for long enough, they’ll eventually decay away. […]
Telescopes from the ground are bigger, but have to fight the atmosphere. Here’s how to win. In astronomy, seeing farther and fainter than ever before requires three simultaneous approaches. First light, […]
A far-ranging conversation about telescopes, what they do, and who they impact. When most of us think of astronomy, we think about two types of scientists: the observers who point their […]
It wasn’t the birth of space and time. But it was truly essential to our cosmic story. For more than 50 years, we’ve had definitive scientific evidence that our Universe, as […]
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 […]
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 […]
