From galaxies with no dark matter to ones with hundreds of times more dark matter than normal, our Universe needs it more than ever. One of the most mysterious substances in […]

A cosmic puzzle is finally solved, as new observations answer the question of why this galaxy exists at all. For the last couple of years, astronomy has had a tremendous puzzle […]
If there’s no phosphine, there’s no indirect evidence for biological activity there. In one of the biggest surprises in the history of planetary science, a September 2020 study announced the presence […]
Maybe 100% of stars don’t have planets, after all. When stars form in the Universe, they’re created in giant bursts. A stellar nursery in the Large Magellanic Cloud, a satellite galaxy […]
Everything on Earth is made of atoms and their building blocks. Without this one rule, they’d never make anything interesting. Take a look around you at everything on Earth. If […]
Delaying or refusing vaccines for non-medical reasons is literally a killer choice. When it comes to issues at the intersection of science and society, there are all sorts of things that […]
We’ve argued over ideology for far too long. It’s time to pick a better route to prosperity. In every civilized society around the world, there’s a trade-off that must be […]
Geologists may have spotted evidence of the beginning stages of a subduction zone, a process that drives the movement of Earth's tectonic plates.
LIGO just announced the second neutron star-neutron star merger ever seen in gravitational waves. It doesn’t match the first. On August 17, 2017, an event occurred that forever changed how we […]
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 […]
The laws of physics are not time-reversal invariant. Here’s how we know. No matter when, where, or what you are in the Universe, you experience time in only one direction: forwards. […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
New research on ankle exoskeletons show promising results.
The history of the Universe is forever imprinted in our own bodies. We can learn a lot about the history of the Universe just by looking at each of our own […]
Black hole mergers are some of the most energetic events in the Universe. Could the gravitational waves they produce ever harm us? The Universe is not a static, stable place. Out […]
Isogloss cartography shows diversity, richness, and humour of the French language
There was less than a 2 second delay between gravitational waves and light, but that’s incredibly meaningful. There’s an important rule in relativity that — as far as we know — all objects must […]
The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]
Some of them may have formed just 200 million years after the Big Bang. When we look out at the Universe, we’re not seeing objects as they are today, but rather […]
One often-neglected result of climate change is ocean acidification. If this process continues, we may start to see fewer fish and more jellyfish.
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
There’s a million things we haven’t done. But just you wait. The Universe as we know it began some 13.8 billion years ago with the onset of the hot Big Bang. […]
Despite all the challenges, Hubble has vindicated this discovery. Practically everywhere we look in the Universe, the large-scale objects that we see — small galaxies, large galaxies, groups and clusters of galaxies, […]
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
It’s 100 years since astronomy’s famous ‘great debate.’ We still haven’t learned the most compelling lesson of all. So, you’ve arrived at a crossroads: you think the world works in a […]
Remember the announcement of a galaxy with no dark matter? It’s just been re-examined, with astounding results. In theory, all galaxies should contain copious amounts of dark matter, with one […]
Even if you remove everything you can from the Universe, some energy will still remain. Here’s what that means. Imagine, if you can, what it would mean to have a Universe […]
The most massive nearby stars could be the seeds our supermassive black holes need. The problem with the Universe, as we see it today, is that we only get a snapshot […]
If economic growth knowingly increases mass-scale suffering, can we stop chasing it?
The blob that's astonishing science gets its own exhibit.
