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 […]

What do hot dogs, the Vatican, and the Large Hadron Collider have in common? They’re all in our random fact roundup where we bring you some favorite facts about three subjects.
If you think it expanded faster than light-speed, you need to read this. If the Universe is 13.8 billion years old, and the speed of light is truly our cosmic speed […]
Theoretical work tells you where to look, but only experiments can reveal what you’ll find. There are fundamental mysteries out there about the nature of the Universe itself, and it’s our […]
Good news for space exploration?
The legacy of what humanity’s greatest telescope has to teach us about the Universe continues to grow. Here in the Universe, in the Milky Way and beyond, new stars are birthed […]
While the web of dark matter (purple) might seem to determine cosmic structure formation on its own, the feedback from normal matter (red) can severely impact galactic scales. Both dark […]
Scientists pick up signals from an explosion of electromagnetic energy that occurred when a black hole ripped apart a passing star.
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 […]
Our understanding of the universe has expanded tremendously in the last few decades. But there are still some mysteries out there, and the Great Attractor is one of them.
What happened 4.56 billion years ago is the most important part of the cosmic story ever to happen to us. If you were to look at our Universe at the time […]
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 […]
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 […]
Gravity gets weaker as the distance squared. But gravitational waves only get weaker as the distance. Why? One of the things we often just accept about the world is that […]
The indirectly find was completely unexpected, and, if it holds up, could give the James Webb Space Telescope its first tantalizing target. In the quest to understand our Universe, and […]
Congress refused the majority of Trump’s proposed cuts to NASA’s budget. But many uncertainties remain. On March 21st, 2018, both branches of Congress passed the United States’ Consolidated Appropriations Act, […]
The Event Horizon Telescope has come online and taken its data. Now, we wait for the results. Black holes are some of the most incredible objects in the Universe. There are […]
The chances of an asteroid large enough to be a threat to areas where human beings are concentrated are small. Still, it’s what’s known as a “high impact” result.
The entire device is about the size of an ice chest, and the temperature it achieves will be 10 billion times colder than the vacuum of space.
The expanding Universe really is accelerating, and no dusty scenario can explain it. 20 years ago, our understanding of the Universe underwent a revolution. For generations, we had known the Universe […]
Sometimes, the biggest answers to the deepest questions come in the most unexpected of places. In the Solar System, anything out past Neptune is generally considered to be the outer reaches […]
For perhaps 100 million years, there were no stars in the Universe. What was it like then? The earliest stages of the Universe were extraordinarily eventful in bringing us about. Cosmic […]
There are no punches to pull here. If America believes in science, research, or basic truths about the Universe, we cannot cancel this mission. Last week, the White House released their […]
The ‘giant impact’ that led to Earth might not have been so giant, after all. A little over 4.5 billion years ago, our Solar System began to form. Somewhere in the […]
Not building one means giving up on brute force. We’re not yet ready to do that. There’s a problem with the field of high-energy physics, and it’s the biggest one imaginable. […]
Really puts the whole “don’t give up until you’re dead” thing to shame.
Three great things all align this August, making the Perseids a can’t-miss show. Here’s how to take advantage. When it comes to meteor showers, we have these dazzling pictures in […]
The launch of SpaceX’s Falcon Heavy was widely covered by the media, but one astrophotographer wanted a different kind of shot of the Tesla Roadster tumbling through space.
LIGO, here on Earth, has exquisitely-precise distances its lasers travel. With three spacecrafts in motion, how could LISA work? Since it began operating in 2015, advanced LIGO has ushered in an […]
All the planets, asteroids, and Kuiper belt objects out there all point to the same conclusion: it’s giant impacts or no moons at all. Out of all the rocky planets […]
