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 […]
We’ve put so much together about the Universe. Could it all come tumbling down? We’re always on the lookout for the next big thing, and even our best guesswork is often […]
There is a fundamental difference between matter and antimatter. But not enough of one to explain our Universe. Our Universe is a vast and enormous place, and if there’s one […]
For more than 10 billion years, the star-formation rate across the Universe has been plummeting. Here’s the story. Take a look at a wide variety of galaxies in the Universe, and […]
The Big Bang happened everywhere at once, but stars are a different story. The Universe, back at its inception, was almost perfectly identical everywhere. It was the same high temperature […]
The most massive star in the known Universe is 260 times as heavy as our Sun. But viewing the early Universe will shatter that record. Place enough mass together in one […]
If your goal was to destroy the science of astronomy and astrophysics, this is exactly how you’d do it. One of the perks of being President of the United States of […]
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 […]
If all you see is low-energy light in a myriad of directions, you can’t be sure. But this light comes from the Big Bang. There are a lot of things that […]
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 […]
A new set of images from NASA’s Chandra X-ray observatory shows us what we’ve never seen before. The Pillars of Creation, 7,000 light years away in the Eagle Nebula, represents one […]

Space may be enormous, but collisions are inevitable. Here’s what happens when they occur. The Universe as we know it has been around for nearly 14 billion years: plenty of time […]
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 […]
Shortly after the Big Bang, the Universe became completely dark. The first stars, when they ignited, changed everything. For perhaps 100 million years, the Universe was devoid of stars. The […]
The truth might not be ‘out there’ at all. There may never have been another intelligent, technologically advanced alien species in the entire history of the Universe. When you take into […]
As wonderful as the evidence that supports or invalidates a theory is, it can never truly kill the ones that don’t work out. When it comes to science, we like to […]
