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. […]

Researchers find what causes the glow coming from the densest objects in our universe.
Filaments, hundreds of millions of light-years long, were just caught spinning. In our own cosmic backyard, everything we see spins, rotates, and revolves in some fashion or other. Our planet […]
If dark energy gets stronger with time, our fate could be an utter catastrophe. When it comes to the entire Universe, one of the biggest existential questions we’re capable of […]
Need a distraction during these stay-at-home times? Look up tonight to see the first supermoon of spring.
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 […]
When you view your right hand in a mirror, it appears as a left hand. Writing is reversed, as is the direction of any spinning object: clockwise becomes counterclockwise and […]
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 […]
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 […]
It’s one of only five spacecraft that will exit the Solar System, and the only one we have a chance to aim at another star. Of all the spacecraft ever launched, […]
New research proposes possible origins of the interstellar object ‘Oumuamua.
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
When one group says “A” and another group says “B,” consider that everyone might be wrong. One of the biggest enemies of scientific truth is the setup of a false dichotomy. […]
Two of our biggest science-fiction dreams might not remain fiction for much longer. Here’s how 21st-century science could make it real. For as long as human beings have looked up at […]
The top of Mauna Kea is the ideal physical site for this new, ready-to-be-built telescope. But that’s far from the only concern. For many years, astronomers have looked forward to a […]
If a large asteroid strikes Earth, it has the potential to release an enormous amount of energy, leading to local or even global catastrophes. The strike that led to the […]
If this newfound galaxy is just the tip of the iceberg, the entire Universe may fall into place. One of the greatest challenges for a scientist is that every time you […]
The biggest error from ‘A Brief History of Time’ continues to misinform generations of aspiring physicists. The greatest idea of Stephen Hawking’s scientific career truly revolutionized how we think about […]
We still don’t know how it came to be this way. Every once in a while, we find an object in the Universe that completely mystifies us. For generations, astronomers have […]
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
A black hole’s event horizon is thought of as the point of no return. But perhaps there are ways back out, after all. Black holes just might be the most extreme […]
Small sample size? No underlying theory? Conflicts with all other results? It checks all the boxes. There’s nothing that’s special, on a cosmic scale, about our place in the Universe. Not […]
If they saw us as we were before the recent industrial revolution, would there be any reason to particularly care about us? All across the Universe, trillions of galaxies can be […]
Astronomers have recently discovered the most massive neutron star to date, nearly at the theoretical limit for such stars. But it’s only about the size of a small city.
An Oxford scientist’s controversial theory rethinks dark matter and dark energy.
NASA astronomer Michelle Thaller explains what astronomers actually do, and how can you become one.

An amateur astronomer discovers an interstellar comet on its way to our Sun.
Hawking radiation should really be happening, but black holes are farther from decaying than ever before. Black holes are, in many ways, the most extreme objects that will ever exist in […]
From outside a black hole, all masses take an infinite amount of time to cross the event horizon. How, then, can black holes grow? Every Milky Way-sized galaxy should contain hundreds […]
