Trace how culture, power, and ideas shape societies across time.
We still don’t know how it came to be this way. Every once in a while, we find an object in the Universe that completely mystifies us. For generations, astronomers have […]
Here’s how the closest place to “hell” in our Solar System might actually be home to life. From afar, Venus seems like the most uninhabitable planet of all. NASA’s Magellan mission […]
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 […]
There’s a lot left to understand, ponder, and investigate. And there always will be. For hundreds of thousands of years — nearly all of human history — we had no definitive answers to some of […]
From the right place at the right time, it’s a sight unlike any you’ll find on Earth. In our Solar System, any planet with moons has a chance for a solar […]
It’s perhaps the most famous thought experiment in all of physics, but is full of popular myths and misconceptions. One of the most bizarre ideas about the quantum Universe is […]
Without a little help from Einstein, we couldn’t have made this discovery. NASA’s Hubble Space Telescope, currently celebrating its 30th anniversary, still churns out novel discoveries. The Hubble eXtreme Deep […]
This year’s June solstice coincides with a new Moon and an annular solar eclipse. Here’s how rare it truly is. As the Earth orbits the Sun, it rotates on its axis. […]
Nothing in the Universe can travel faster than the speed of light. So how does space itself do it? One of the fundamental rules we all learn in physics — set forth by […]
Too little breathing room, tear gas, and insufficient masks are a recipe for disaster. Police are worsening all three. Across the nation and the world, people of all skin colors are […]
Solid, liquid, and gas are the three everyone learns. Plasma is the fourth. But there are two more, and they’re fascinating. How many states of matter are there? When you […]
We’re looking back farther in time than ever before. Here’s what we’re finding. Even today, the Universe is forming enormous numbers of new stars: from various nebulae throughout our galaxy to […]
The origin of the 3rd element on the periodic table was one of the great cosmic mysteries. We just solved it. How did we form the elements that pervade the Universe […]
It’s not only about what’s happening right now. Things need to change for good. It could be your colleague, your coworker, your staff member, or your student. As the world mourns […]
It’s not just about SpaceX and Starlink. What we’re deciding today will have a global impact for years and decades to come. For countless millennia, human beings have gazed up into […]
In order, they go: hydrogen, helium, oxygen, carbon, neon, nitrogen, magnesium, silicon, iron, sulfur. Here’s how we made them. Everything found on planet Earth is composed of the same ingredients: atoms. […]
There’s some amazing science happening at the South Pole, but some very grandiose claims being made. What’s actually going on? For some of us, the idea of parallel Universes spark our […]
Find a clear western horizon after sunset, and this ‘triple treat’ of a dance can be yours. Every once in a while, the night sky provides a spectacular feast for our […]
There are three things your new theory must do in order to be taken seriously as science. This one’s 0-for-3. Every once in a while, a revolutionary idea comes along that […]
They say that seein’ is believin’. But everything we see has to have a scientific explanation. When you look at the Sun on a day where there’s a clear sky, […]
