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. […]

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 […]
It isn’t just that mass and energy are equivalent and interchangeable. It tells us something fundamental about mass itself. Of all the equations that we use to describe the Universe, perhaps […]
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 […]
Groundbreaking new research suggests gamma-ray bursts are caused by a star’s collapsing magnetic field.
Pfizer’s vaccine needs to be kept at -100°F until it’s administered. Can caregivers deliver?
Need a distraction during these stay-at-home times? Look up tonight to see the first supermoon of spring.
And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]
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 […]
It’s not just for Earth-like planets around Sun-like stars. Not even close. Shortly after Earth first formed first formed, life quickly took hold, thriving ever since. Both reflected sunlight on a […]
Forget about alien nonsense. The Universe as it actually is doesn’t need any embellishments to be interesting. In our Solar System, the planets, moons, asteroids, comets and other masses are […]
The Eagle Nebula, complete with the Pillars of Creation, tells a mini-version of the story of how all the Universe’s stars formed. The Eagle Nebula, found 7,000 light-years away, demonstrates how […]
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.
Researchers think they know how a group of ancient sloths, who died thousands of years ago in Ecuador, met their untimely end.
A new device shows promising results in its ability to convert CO2 and water into useful fuels.
And it’s not because of leap seconds; it’s a fundamental property of most days. Human beings, in marking the passage of time, account for each day equally: with 24 hours. One […]
Even though it was the crowning achievement of Einstein’s career, he was only a small part of the full story. If you were a physicist in the early 20th century, there […]
We have to use the right definition for the specific question we’re asking. When it comes to the Universe, we frequently characterize objects by examining and reporting on their physical […]
Or is ‘new space’ created in between the gaps of the ‘old’ space? It’s been almost 100 years since humanity first reached a revolutionary conclusion about our Universe: space itself doesn’t […]
Telescopes from the ground are bigger, but have to fight the atmosphere. Here’s how to win. In astronomy, seeing farther and fainter than ever before requires three simultaneous approaches. First light, […]
Atop certain glaciers are herds of small mossy balls that somehow move together when no one’s looking.
Many of them are spinning at nearly the speed of light. When you do the math, there’s no other way it could have been. Take a look out there at the […]
A 71% wet Mars would have two major land masses and one giant ‘Medimartian Sea.’
A gigantic star makes off during an eight-year gap in observations.
Sometimes not looking forward to something helps you get it done.
Being ahead of the curve can be a dangerous place. These 7 thinkers were driven from their homelands over it.
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
Here’s how to harness the sunlight, even if you’re sitting in an office all day.
Combining two fabrics is the best way to filter out infectious coronavirus particles according to a new study.
