A new paper combines two concepts from the edges of astrophysics: Dyson Spheres and black holes. A Type III civilization could combine them.
The Schumann resonances are the background hum of the entire planet. But they don’t affect humans in any way.
With radio and X-ray data combined, we’re understanding how energy flows like never before. When we look out at the Universe on the largest cosmic scales of all, gravity is the […]
Quantum entanglement may remain spooky, but it has a very practical side.
The majority of the matter in our Universe isn’t made of any of the particles in the Standard Model. Could the axion save the day?
Venus Life Finder could launch as early as 2023.
Creating an afterlife—or a simulation of one—would take vast amounts of energy. Some scientists think the best way to capture that energy is by building megastructures around stars.
If we’re migrating slowly away, is our speed changing, too? Every year, planet Earth completes one revolution around the Sun while spinning on its axis. On a year-to-year basis, our […]
This year’s Nobel Peace Prize ceremony sends yet another strong message to Russian president Vladimir Putin.
Out of the four rocky planets in our Solar System, only Earth presently has plate tectonics. But billions of years ago, Venus had them, too.
A Harvard professor’s study discovers the worst year to be alive.
Many were expecting extremism survivor and free speech advocate Salman Rushdie to take home the Nobel Prize in Literature, but Annie Ernaux beat him to it.
In 2017, a kilonova sent light and gravitational waves across the Universe. Here on Earth, there was a 1.7 second signal arrival delay. Why?
The 72-meter wingspan is lined with solar panels to give the plane the power it needs to stay airborne for nearly three months.
In 1957, humanity launched our first satellite; today’s number is nearly 10,000, with 500,000+ more planned. Space is no longer pristine.
The right questions are those sparked from the joy of discovery.
By digging deep, we could harness enough energy to power generations to come. But it involves fracking.
Researchers discovered a galactic wind from a supermassive black hole that sheds light on the evolution of galaxies.
Nothing lives forever, at least, not in the physical Universe. But relativity allows us to get closer than ever, from one perspective.
So far, gravitational waves have revealed stellar mass black holes and neutron stars, plus a cosmic background. So much more is coming.
How can we understand mysterious planets like Jupiter? Use giant lasers!
And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]
If nature were perfectly deterministic, atoms would almost instantly all collapse. Here’s how Heisenberg uncertainty saves the atom.
Such massive, early supermassive black holes have puzzled astronomers for decades. At last, we’ve finally figured out how they form.
Stars are born, live, and die within the spiral arms of galaxies like the Milky Way. These 19 JWST spirals deliver unprecedented riches.
A new model of the Antikythera mechanism reveals a “creation of genius.”
Michael Faraday’s 1834 law of induction was the key experiment behind the eventual discovery of relativity. Einstein admitted it himself.
Shortly after planet Earth formed, life took a permanent hold on our surface. But just how common is such an outcome?
Inflation, dark matter, and string theory are all proposed extensions to the prior consensus picture. But what does the evidence say?
