And what can it teach us about our Solar System’s earliest days? In many ways, astronomy is unique among the sciences. In every other field, you have the ability to design […]
Many people, including some scientists, fear that the coming 5G WiFi revolution will harm humans. Here’s why that’s unfounded. Over the coming few years, a new set of infrastructure will […]
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 […]
It’s not the only one of its kind, but it’s definitely makes no sense without dark matter. Throughout the Universe, galaxies and star clusters come in all different sizes and masses. […]
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, […]
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 […]
Here's a look at the space agency's astronaut candidate requirements.
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 question that's baffled physicists for nine years has been resolved by the simplest possible answer.
It’s absolutely true that atoms are mostly empty space. But removing even that empty space is impossible, and this is why. If you were to take any object in the Universe […]
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 […]
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 […]
Study shows ripples across a newly fertilized egg are similar to ocean and atmospheric circulations.
What could be better than "do unto others as you would have others do unto you"?
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 […]
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 […]
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 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 […]
Debris from Pluto-sized collisions, not aliens, are streaming through the galaxy. In 2017, scientists discovered an object passing through our Solar System that was unlike anything else we had ever seen. […]
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 […]
In physics, anything that isn’t forbidden must occur. So why don’t the strong interactions violate CP-symmetry? If you ask a physicist what the biggest unsolved problem facing the field today […]
"We need to get our priorities straight," Warren said.
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. […]
New research on ankle exoskeletons show promising results.
Entropy always increases, but that doesn’t mean it was zero to start with. One of the most inviolable laws in the Universe is the second law of thermodynamics: that in any […]
