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 […]
