Only 8 worlds make the astronomical cut as planets. Here are the 10 fascinating bodies that didn’t make it. Astronomically, bodies within the Solar System must achieve three criteria in order […]

It’s either a cosmic mystery or a terribly mundane mistake. The Universe is expanding, and every scientist in the field agrees with that. The observations overwhelmingly support that straightforward conclusion, and […]
Proxima Centauri, our closest star, is more than 4 light years away. Reaching it under 10,000 years will be challenging; reaching it with living humans will be even harder.
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 […]
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 […]
The Earth is getting warmer, and humans are the cause. This is why. Let’s play pretend for a moment. Pretend, if you can, that you’ve never heard about the idea of […]
Our Universe is full of surprises. This latest one, AT2018cow, has ignited a controversy between astronomers. The Universe is an ever-changing place, particularly if you look at it on long-enough […]
The Canadian professor takes issue with blocking free speech, but is he part of the problem?
The road to harmony often means getting your hands dirty.
The world’s greatest clockmaker sent a clock to the new world, and everything went haywire. The reason why will shock you. For millennia, humanity’s one-and-only reliable way to keep time was […]
Binary stars and common envelope evolution illustrate messy but “tasty” science.
If dark energy were stronger or weaker, everything would be pretty much the same. And that’s a puzzle. After the Big Bang, the Universe was full of matter and radiation. It […]
Dark matter, dark energy, inflation and the Big Bang are real, and the alternatives all fail spectacularly. If you keep up with the latest science news, you’re probably familiar with […]
Even the best science imaginable has its limits. In terms of ambition, it’s hard to ask for more than to know absolutely everything there is to know about the Universe. That’s […]
As individuals, we scientists are all flawed. But the enterprise of science rises above our individual shortcomings. The enterprise of science is perhaps the greatest achievement in all of human […]
One moment, every particle in the Universe was massless. Then, they weren’t anymore. Here’s how it happened. In the earliest stages of the hot Big Bang, the Universe was filled […]
Dark energy is pushing distant galaxies apart from one another at an increasing rate. If the Big Rip hypothesis is true, things will only get worse from here. One of the […]
In all the years of NASA, we’ve never touched the Sun before. Here’s why it’s so hard. This past weekend, NASA successfully launched the Parker Solar Probe: the first spacecraft that […]
An Oxford physicist tries to cast doubt on dark energy, but the data says otherwise. It was a mere 20 years ago that our picture of the Universe got a […]
With every second that goes by, tens of thousands of star disappear from our reach. And it’s getting worse. It’s been nearly a century since scientists first theorized that the Universe […]
When two different techniques give two different results, either someone is wrong, or something incredible is happening. Imagine you were a scientist attempting to measure some property of the Universe. […]
Fundamental physics must reconsider its current path and value system.
A quarter-million years of evolution can’t be wrong.
20 years ago, we discovered that distant galaxies were accelerating away from us. Here’s how the Universe makes it happen. Matter and energy tell spacetime how to curve; curved spacetime tells […]
Most basic form of data, meet most basic form of matter.
LIGO and Virgo have now detected a total of 11 binary merger events. But exactly 0 were in the Milky Way. Here’s why. One of the most spectacular recent advances in […]
The heaviest elements in the periodic table have their own unique story. No, they don’t come from a supernova. When it comes to the elements of the Universe, every one […]
In the Western world, there’s a constant pressure to be happy. Paradoxically, this makes people more prone to anxiety and depression.
