Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
There’s a boundary to how far back we can observe everything that exists. Despite everything we’ve learned about our Universe, there are many existential questions that remain unanswered. We don’t know […]
How quickly is it expanding today, and how does that expansion rate change over time? What is the Universe made of? How quickly is it expanding today, and how does that […]
Our galactic home in the cosmos — the Milky Way — is only one of two trillion galaxies in the observable Universe. Our galactic home in the cosmos — the Milky Way — is merely one among the […]
For the first time in many years, there’s currently a comet visible to the naked eye in Earth’s night sky: comet NEOWISE. For the first time in many years, there’s currently […]
Without quantum physics, the Sun wouldn’t shine at all. Earth, as we know it, is only teeming with life because of the influence of our Sun. Its light and heat provides […]
For northern hemisphere skywatchers, it might just be the century’s best comet so far. Every once in a while, large, icy objects pass through the inner Solar System. C/2014 Q2 (Lovejoy) […]
5 years ago, LIGO detected our first gravitational waves here on Earth. Next decade, LISA will start seeing them from space. When it comes to gravitational waves, our terrestrial laser interferometers […]
The biggest error from ‘A Brief History of Time’ continues to misinform generations of aspiring physicists. The greatest idea of Stephen Hawking’s scientific career truly revolutionized how we think about […]
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 Standard Model and General Relativity can’t be all there is. But how will we discover what lies beyond them? One of the biggest problems with physics is that, apart from […]
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 […]
CERN’s bold new proposal has physicists confronting the biggest question of all: is building a new collider worth it? If you want to discover anything novel about the natural, physical […]
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. […]
You never know what you’re going to find when you look somewhere new for the first time. Approximately 4600 feet (1400 meters) underground, beneath the Italian mountain known as Gran Sasso, […]
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 […]
