Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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 […]
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 […]
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 […]
They’re one of the brightest windows into our Universe’s star-forming past. When we look out at the galaxies in the Universe, almost all of them have supermassive black holes at […]
As the Universe ages, will it eventually fade away entirely? The earliest signal we’ve ever directly detected from the Universe comes to us from shortly after the Big Bang: when […]
There could have been life on Mars in the past, but that’s only the beginning of the story. For as long as humanity has been watching the skies, we’ve been fascinated […]
It comes from a supernova seen just 33 years ago, and it doesn’t pulse. 33 years ago, a supernova occurred just 168,000 light-years from Earth. This new image of the supernova […]
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
It doesn’t have to be a science-fiction dream. For as long as human beings have been watching the night sky, we’ve dreamed of visiting other worlds and truly seeing what’s […]
How can we save humanity from ourselves? In this life and this Universe, there will always be questions beyond the capabilities of humanity to answer. There’s so much that we’ve […]
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 […]
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 […]
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 […]
