For thousands of years, we puzzled at how far away the Moon was. Today we know its distance, at any time, to within millimeters.
An annular eclipse is coming to Earth on October 14, 2023. Six months later, a total solar eclipse is headed our way. Here’s the reason why.
This oddball system of three stars might be our best chance at finding nearby life in the Universe.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
If you look into a mirror, you’ll notice that left-and-right are reversed, but up-and-down is preserved. The reason isn’t what you think.
Centuries ago, the plague forced people into quarantine for years. Isaac Newton and Galileo used the time to revolutionize the world.
The transformational change driven by AI will elevate neurodiversity inclusion as an organizational asset, argues Maureen Dunne.
Sun-like stars live for around 10 billion years, but our Universe is only 13.8 billion years old. So what’s the maximum lifetime for a star?
The multiverse pushes beyond the limits of the scientific method. From our vantage point in the Universe, we cannot know if it’s real.
How did the troughs form?
Known as orphaned planets, rogue planets, or planets without parent stars, these “outliers” might be the most common planet of all.
Many people out there, including scientists, claim to have discovered a series of game-changing revolutions. Here’s why we don’t buy it.
There’s an extra source of massive “stuff” in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
Whether you call it 10 quintillion, 10 million trillion, or 10 billion billion, it’s a 1 followed by 19 zeroes.
We’ll never be able to extract any information about what’s inside a black hole’s event horizon. Here’s why a singularity is inevitable.
Grief never ends. There is no closure, but there are things we can do to mitigate the feeling of loss.
The outer planets’ clouds hide the weirdness within.
The multiverse is an idea that has gained a lot of traction in popular culture. But what does science have to say about it?
What do we mean by a black hole’s size? A photon sphere? The minimal stable orbit? The event horizon? The singularity? Which one is right?
There are at least 15 different types of solid water (ice). Now, scientists believe that there might be a second type of liquid water.
Explanations for the cosmic speed limit often conflate mass with inertia.
No matter how hard we try, we will never reach a final theory that unifies scientific knowledge. The very nature of science doesn’t allow it.
Social media distorts the reality of the public sphere.
Not too hot, not too cold…
Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
With two different black hole event horizons now directly imaged, we can see that they are, in fact, rings, not disks. But why?
After 15 years of monitoring 68 objects known as millisecond pulsars, we’ve found the Universe’s background gravitational wave signal!
