We’ve never seen an image of a black hole’s event horizon before. Here’s what we’re expecting, based on what we already know. For hundreds of years, physicists have hypothesized that the […]

If a star spins and then collapses, what happens to its angular momentum? The most common way to form a black hole in the Universe is to have a massive […]
Flattening the curve on panic and disinformation.
You get out what you put in, and we haven’t truly invested in space since Apollo ended. Humanity should be an interplanetary civilization by now. There is no scientific reason that […]
If galaxies are cities in the Universe, how unfortunate that our ‘cosmic country’ is dissolving. On the largest cosmic scales of all, planet Earth appears to be anything but special. […]
We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]
Two new papers say everything we knew about black holes was wrong.
What’s more massive than the heaviest known neutron star but lighter than the lightest known black hole? LIGO may be about to solve that mystery. Whenever a star is born in […]
When people learn the Universe is expanding, they want to know where the center is. The ‘answer’ isn’t what they expect. There are two things that people learn about the Universe […]
The closest star to our own doesn’t just host one rocky planet, but a second, larger ‘super-Earth’ much farther out. Of all the stars in the Universe, the closest one to […]
The Sun will eventually become a red giant star, swallowing Mercury and Venus in the process. But what will happen to Earth? There are a few existential questions we can ask […]
And what do we still have left to learn? The original idea of a black hole goes all the way back to 1783, when Cambridge scientist John Michell recognized that a […]
Some have suggested that there is no hidden giant out there.
If antimatter falls up instead of down, countless sci-fi dreams will become scientific reality. One of the most astonishing facts about science is how universally applicable the laws of nature […]
It’s one thing to find a galaxy that “shouldn’t exist.” It’s quite another to learn why it does. Above a certain size, spiral galaxies shouldn’t exist. A single major merger — where two […]
New experiments look to the interplay between neutrons and magnetic fields to observe our universal reflection.
Proxima Centauri, our closest star, is more than 4 light years away. Reaching it under 10,000 years will be challenging; reaching it with living humans will be even harder.
A young star and a belt of gasses give the game away.
The Universe is expanding, but we, our planet, solar system and galaxy all aren’t. Here’s why. Take a look out at almost any galaxy in the Universe, and you’ll find it’s […]
Its scarcity could impact scientific research as well as the high-tech industry.
It’s not a question we know enough to know the answer to, but to dismiss the possibility is scientifically baseless. There’s one question that most of us ask at some […]
How can physics on the smallest scales affect what the Universe does on its largest ones? Cosmic inflation holds the answer. On a macroscopic level, the Universe appears to be entirely […]
If you’re wondering whether the blast wave or the radiation would kill us first, you’re asking the wrong question. As far as raw explosive power goes, no other cataclysm in […]
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 […]
Dark matter, dark energy, inflation and the Big Bang are real, and the alternatives all fail spectacularly. If you keep up with the latest science news, you’re probably familiar with […]
Our future fate is likely already determined. If we end in a Big Crunch, what does that mean? The ultimate fate of the Universe is one of the biggest existential questions […]
A new method promises to capture an elusive dark world particle.
It’s the first time humans have landed a spacecraft on the far side of the moon.
Our Universe cannot be described by normal matter alone. Vera Rubin’s work led the way. Ask an astrophysicist what our Universe is made of, and you’ll likely receive a shocking surprise. […]
