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 […]

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 […]
The first planets were only gas. The second included rocky ones, but life wasn’t possible. Here’s how we finally got there. Here in the Universe today, potentially habitable planets are practically […]
Immediately after the Big Bang, the Universe was more energetic than ever. What was it like? When we look out at the Universe today, we see that it’s full of stars […]
What are the different types of rocket engines and will there be a rocket engine coming in the future that uses very little energy? NASA’s Michelle Thaller explains.

Any exercise is better than none, but no one wants to waste their time in the gym. Learn how to get the most out of your workout here.
The Universe began almost perfectly uniform, while today, it’s anything but. Here’s how we grew up. One of the strangest facts about the Universe is how dramatically its changed over time. […]
Two new papers say everything we knew about black holes was wrong.
The most surefire, easily-seen signature of life on Earth might be a cosmic red herring around other worlds. In our quest for life beyond the Solar System, it makes sense to […]
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 […]
Blame our ancestors for why it’s easier to be a couch potato.
The cosmic story of us, from before the Big Bang until today, is a story that all of us share. Enjoy it, in just 200 words. In the beginning, there was […]

The neuralnanorobotics are coming.
In 1987, we detected neutrinos from another galaxy in a supernova. After a 30 year wait, we’ve found something even better. One of the great mysteries in science is determining not […]
For 100 million years, there was only creation in the Universe. Meet our first moments of destruction. The cosmic story that gave rise to us is a story rife with […]
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 […]
When he was developing his famous hierarchy of needs, Abraham Maslow cited 9 historical figures that achieved self-actualization.
In the earliest stages of the Universe, before there were protons or neutrons, we had a quark-gluon plasma. The story of our cosmic history is one of an expanding and […]
Not all states are feeling the effects equally.
Before there were gravitational waves, multi-messenger astronomy got its start with the neutrino. Sometimes, the best-designed experiments fail. The effect you’re looking for might not even occur, meaning that a […]
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 […]
He reminds us that meaning is wherever we choose to look.
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 […]
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 […]
The Boomerang Nebula, in our galaxy, is even colder than completely empty space. Here’s how that’s possible. Imagine the coldest place you possibly can. Inside it, the particles that make […]
These cosmic behemoths were enormous from very early times. Here’s how they came to be. One of the biggest challenges for modern astrophysics is to describe how the Universe went from […]
