Our galactic home in the cosmos — the Milky Way — is only one of two trillion galaxies in the observable Universe. Our galactic home in the cosmos — the Milky Way — is merely one among the […]

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 […]
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 […]
Something isn’t adding up, but it isn’t a calibration error. It’s been nearly 100 years since we discovered that the Universe was expanding. Ever since, the scientists who study the […]
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.
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 […]
NASA astronomer Michelle Thaller explains what astronomers actually do, and how can you become one.

It’s a supergiant star in the final stage of its life, and it just dimmed by an enormous amount. What’s going on? When you take a look at the stars in […]
2019 offers an outstanding selection of books, accessories, and much more for the science-lover in your life! With each passing year, a whole slew of new scientific discoveries, refinements, and improvements […]
There are three possible ways we’ll find alien life. With all of these chances, the only question is which will come first. Given everything humanity has learned about the Universe, it […]
If you traveled in a straight line for far enough, would you come back to where you started? If you were to set out on a journey from anywhere on Earth’s […]
An amateur astronomer discovers an interstellar comet on its way to our Sun.
With tens of thousands of satellites requiring AI-control to avoid collisions, a single solar flare could everything. Over the next few years, the night sky and the volume of space […]
Unlike most articles that are titled with a question, the answer isn’t automatically “no.” Announced on January 6, 2020, NASA’s TESS mission has just discovered its first Earth-sized, habitable zone […]
Stronger than the LHC and faster than anything except light, the world’s cleverest particle detector sees the particles we could never create on Earth. It might be true that there’s an […]
And can we devise an experiment to tell, even when we aren’t looking? One of the most bizarre aspects of quantum physics is that the fundamental entities that make up the […]
The TESS satellite captures rare images of a cataclysmic event in a faraway galaxy.

A binary white dwarf in a tight, super-fast rotation looks to be pumping out gravitational waves.
We may find signs of life a mere 31 light-years away.
Objects coming into our solar system have an origins story to tell.
Think there are habitable super-Earths out there? Think again. Here in our Solar System, we have two very distinct types of planets: small, terrestrial, rocky worlds, with thin (or no) atmospheres […]
Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility.
It’s not a gambit. It’s not fraud. It’s not an opinion. And it’s not biased like you think it is. Most of us, when we think about what science is, default […]
This exoplanet is 10 times hotter than any world we measured and shaped like a football.
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 […]
Since the late 1800s, what we know has advanced light years ahead.
Are dark matter and dark energy both two sides of the same coin? When it comes to the Universe, what you can easily see isn’t always reflective of all there is. […]
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
It’s a great scientific opportunity of modern times, but we won’t get there with our current observatories. One of the holy grails of modern science is to find a world, […]
