Only 17 years after its discovery have we learned we’re safe from asteroid Apophis. Ever since its 2004 discovery, asteroid 99942 Apophis has threatened planet Earth. Asteroid Apophis has been measured […]

Civilization is facing an existential threat from climate change. Will we humans make it? Does anyone in the universe make it?
Scientists have known blobs existed for a long time, but how they have behaved over Earth’s history has been an open question.
Each year in mid-August, Earth plows through the debris stream of an enormous comet, creating the Perseids. 2023’s show will be magnificent!
Today, it’s common knowledge, but it took scientists centuries to figure out.
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 […]
A volley of new insights reignites the debate over whether our choices are ever truly our own.
Dark matter must gravitate, so why couldn’t the graviton solve it? One of the most puzzling observations about the Universe is that there isn’t enough matter — at least, matter that we know […]
And, if we have one, how close are we to it? No matter which direction we look in, or how far away our telescopes and instruments are capable of seeing, the […]
Researchers discovered a galactic wind from a supermassive black hole that sheds light on the evolution of galaxies.
We’ve already observed three cases where it’s happened. When you look at an object in space, it’s pretty easy to tell if it’s a star or a planet. Stars are […]
Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.
The largest moon in our Solar System, often overlooked, is a water-rich world. Does that mean life? Here on Earth, life took hold very early on in our planet’s history, and […]
A marine scientist explains the threat of the Loop Current, a 800-pound gorilla of Gulf hurricane risks.
Our ultimate fate depends on something we’ve barely begun to measure. One of the biggest mysteries in all of physics is dark energy. According to our best observations, the Universe cannot […]
If you want to get the Universe we see, a multiverse comes along for the ride. When we look out at the Universe today, it simultaneously tells us two stories about […]
Ukraine destroyed a railway to prevent passage from Transnistria into Ukraine.
New chip eliminates the need for specific decoding hardware, boosting gaming systems, 5G networks, and more.
Map shows Europe’s imminent Great Leap Forward in battery cell production
Boredom isn’t the enemy; it’s a catalyst for changing your relationship to work.
From the present day all the way to less than 400 million years after the Big Bang, we’re seeing how the Universe grew up like never before.
If you think it’s just three quarks held together by gluons, you’ll want to read this. At a fundamental level, the Universe is composed of indivisible particles. From macroscopic scales down […]
Although most of the Universe’s mass is dark matter, which gravitates just as well as normal matter, it still can’t make black holes.
The concept of burnout is nothing new. But there are ways to prevent burnout and promote greater engagement with work.
The universe is filled with unlikely events, but is also full of ways to fool ourselves.
Using atoms to probe the Universe reveals the complete Standard Model. If you wanted to uncover the secrets of the Universe for yourself, all you’d have to do is interrogate […]
The shift from steam to electricity was inevitable — but some foresaw it earlier than others.
Are space and time real like atoms are, or is spacetime just a calculational tool? When most of us think about the Universe, we think about the material objects that […]
