It’s not simply Hubble’s Law anymore, but the real history is far more complex than the stories you’ve heard. One of the most mind-blowing facts in our existence is that space […]

Hubble holds the record, finding a galaxy when the Universe was just 3% it’s age. In just a few years, James Webb will shatter it. One of the great scientific lessons […]

When scientists claim that an unexplained phenomenon might be due to aliens, they’re giving up on science. Whenever science discovers a new, unexpected phenomenon, it represents a tremendous opportunity to learn […]

The answer has nothing at all to do with the Higgs boson. In this Universe, there are very few fundamental properties that cannot be derived from something simpler. The rules governing […]

By time you see a pillar at all, almost all of your ‘formation’ is already finished. In the heart of the Eagle Nebula, the iconic Pillars of Creation loom as […]

Despite what Hawking told you, it really isn’t about particle-antiparticle pairs at all. Nothing in the Universe lives forever. All the stars that will ever form will someday burn out; distant […]

Lasers, mirrors, and computational advances can all work together to push ground-based astronomy past even the limits of Hubble. One of the most profoundly remarkable properties about our atmosphere is that […]

The Large Hadron Collider allowed us to complete the Standard Model. Even so, what we have is incomplete. Here’s what could come next. The Large Hadron Collider is the most powerful […]

It took more than 9 billion years for Earth to form: the only known planet housing life. But it could have happened much, much sooner. The cosmic story that unfolded following […]

Your fate is only rarely determined at birth. Ultimately, every star has a chance to get there. Three times in the past 1,000 years, a portion of humanity has looked up […]

These ten ghostly astronomical sights house some deep-and-frightening scientific truths within them. With a huge suite of different observatories for viewing the Universe, innumerable details can be revealed. This ‘Godzilla’ asterism […]

We speak about it, argue over it, and even fight wars for it. We know it when we see it. But just what is energy, anyway? When it comes to being […]

If antimatter falls up instead of down, countless sci-fi dreams will become scientific reality. One of the most astonishing facts about science is how universally applicable the laws of nature […]

From newborn planets to entire galaxies, we’re seeing the Universe as never before. The idea of a modern telescope is simple: collect light from a distant object, at high resolution, and […]

There may be a fundamental reason why time travel, backwards, is impossible. We’ve all had the dream of traveling back in time. Whether there’s a wrong we want to right, […]

Our existence is finite, but that’s no reason for despair. Here’s a version of the story we all should hear at least once. This world, and for that matter, the entire […]

If you’ve ever wondered what truly lies beyond Neptune, this is one interview you won’t want to miss! Our Solar System formed some 4.6 billion years ago from a molecular cloud […]

The cosmic records we have are meant to be broken, but oh, have we ever gone so far. The great cosmic abyss contains more that humanity can ever hope to see, […]

Representation matters. Meet five stellar women in physics who were unjustly denied their place in history. Nobel season is now over, with another year in the books of celebrating the scientists […]

They may have arisen less than 200 million years after the Big Bang, but the Universe was a very different place back then. When you look out beyond the Milky Way […]

No matter what Martin Rees or anyone else says, physics dictates that the world is safe. The Large Hadron Collider is the world’s most powerful particle accelerator. An aerial view of […]

It was Stephen Hawking’s obsession for the last 30 years of his life. Here’s why it matters. When it comes to the sciences, sometimes making two observations or measurements that appear […]

Finding the particle we assume is responsible for dark matter has always been a guessing game. We guessed wrong. You can’t get mad at a team for trying the improbable, hoping […]

Planets can ‘discover’ nuclear power on their own, naturally, without any intelligence. Earth did it 1.7 billion years before humans. If you were hunting for alien intelligence, looking for a surefire […]

As the Event Horizon Telescope prepares to release its first results, we can expect not just one, but two black hole images. What does a black hole actually look like? For […]

NASA’s Chandra X-ray observatory has shown us the Universe like nothing else ever before. When it comes to the Universe, it mainly generates X-rays through high-temperature heating. X-rays from Chandra reveal […]

Instead of eternal expansion, could we just be part of a universal cosmic cycle? There are few questions that can keep us up at night the way pondering the eventual fate […]

On September 27, 1972, scientists performed the first test of Bell’s inequality. God does play dice with the Universe, after all. One of the most puzzling and counterintuitive aspects of quantum […]

Billions of years from now, dark energy will push the rest of the Universe out of reach forever. These galaxies will be the last to go. A look at the night […]

If the Sun is 93 million miles away, why does sunlight filtering through the clouds or the trees spread out? Rays of sunshine are one of those natural sights that leave […]
