It’s one of Einstein’s most bizarre predictions. And it’s true. There’s no such thing as absolute time. No matter where you are, how fast you’re moving, or how strong the gravitational […]

And why, even at its faintest, it always outshines every other star and planet. If you’ve been looking to the west after sunset recently, you may have noticed that there’s one […]
With radio and X-ray data combined, we’re understanding how energy flows like never before. When we look out at the Universe on the largest cosmic scales of all, gravity is the […]
The sacrifices of early astronauts paved the way for Apollo’s successes, and so much more. In all of history, only 24 humans have ever escaped Earth’s gravity. The very first launch […]
Techshot’s 3D BioFabrication Facility successfully printed human heart tissue aboard the International Space Station.
There are many things on large scales that also appear on small scales. But is the Universe truly a fractal? If you take a look at the structures that form in […]
The expansion rate is dropping, but distant galaxies are accelerating. Here’s how. If you take a look at any galaxy in the Universe that isn’t gravitationally bound to our own, we’ve […]
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 […]
We give it the flight plan, and it takes care of the rest. It has to. Here’s why. No matter how advanced our technology becomes, there are certain limits that can […]
How two seemingly distinct exoplanet systems turned out to be related. Practically every star in the Milky Way has a similar origin story. At some point in the past, a molecular […]
The inside of every black hole leads to the birth of a new Universe. Could our Universe have arisen from one?
Have we always had quantum fields in the Universe? Or did they emerge at some finite time? No matter how we look at the Universe — at low temperatures or ultra-high energies, from […]
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
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 […]
If it weren’t for a subatomic quantum rule, our Universe would be vastly different. In many ways, our views of the distant Universe are the closest things we’ll ever get […]
The first Earth-sized planet without a parent star has just been discovered. For countless millennia, planets beyond our Solar System were mere speculation. Today, we know of over 4,000 confirmed […]
Astrophysics has probed a test of a fundamental law, ‘Lorentz invariance,’ well beyond the LHC’s limits. Einstein is still right. The greatest scientific legacy that Albert Einstein left us is this: […]
Grandfathers, take heart. You’ll survive the paradox that’s been gunning for you since the 1930s.
Introducing the Deep Space Food Challenge.
Gravitational wave researchers observe black holes of different sizes colliding for the first time.

Physicists create quantum entanglement, making two distant objects behave as one.
If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go.
The new record-holder opens up a literal Universe full of possibilities. Someday, even our own Sun will eventually run out of hydrogen fuel in its core, bringing a tremendous set […]
The ten greatest ideas in science form the bedrock of modern biology, chemistry, and physics. Everyone should be familiar with them.
If you think life on Earth is hard, wait until you see Mars. If you think life on Earth is hard, try living on Mars. Mars, as photographed from the surface […]
We still don’t know how the information encoded onto it gets out. No matter what you do in the Universe, its overall entropy always increases. Even when we put things in […]
From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.
Everything is being driven apart. But there’s hope of reaching what’s currently so far away. For the first 7.8 billion years, the Universe unfolded exactly as scientists would have expected in […]
Physics demands that it couldn’t be any other way. Here’s why. Ask anyone — even someone with no background in science — to name something that Einstein did, and odds are they’ll come back with […]
