With its frigid temperatures, remoteness from the sun and general dustiness, changing Mars to be more Earth-like is more challenging than it seems (and it already seems pretty tough).
A superconductor is a material that achieves superconductivity— a state of matter that has no electrical resistance and does not allow magnetic fields to penetrate.
Astrophysicists say our universe might be shaped like a three-dimensional donut, meaning you could point a spaceship in one direction and eventually return to where you started.
Theories that attempt to resolve the so-called black hole information paradox predict that black holes are much more complicated than general relativity suggests.
Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance could interact with itself in a higher dimensional universe.
Find out all the science of the Milky Way, including the size of our home galaxy, who discovered it and how it's on a collision course with another galaxy.
The Dark Energy Survey just released its most comprehensive results. But did they really prove Einstein wrong?
Space is big — really big. And if you want to successfully navigate the interstellar depths of our galaxy, you're going to need some sort of reliable system.
The supermassive black hole in the center of our galaxy may not be a black hole at all, but rather a fluffy ball of dark matter called darkinos.
Quantum entanglement is one of the uber-bizarre phenomena seen when things get itty-bitty. Here's a look at how entanglement works and why it's so weird.
For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal — that is, if it looks the same no matter how large the scale.
Physicists have long been unable to describe what happened just after the Big Bang when a teensy blip ballooned into the universe, a process called inflation. We may know why.
Find out what black holes are, who discovered them, how we know they exist and what would happen if you fell into a black hole.
Believe it or not, physicists are attempting to understand the universe when it was only a handful of seconds old.
The hypothetical Planet Nine may not be a planet but rather a small black hole that might be detectable from the theoretical radiation emitted from its edge, so-called Hawking radiation.
New research suggests a way to move heat around "tidally locked" alien planets: ocean currents whipping around the worlds faster than they rotate.
Astrophysicists have a wild idea to explain the bizarre abundance of super-high-energy radiation shooting from the center of our galaxy: gravity portals.
We don't know why the universe is dominated by matter over antimatter, but there could be entire stars, and maybe even galaxies, in the universe made of antimatter.
A weird, super-powerful particle that's not truly a particle could have dominated the universe when it was just a second old, releasing a flood of ripples that permeated all of space-time.
A mysterious "kick" in the early universe may have produced more matter than antimatter. And that imbalance may have also led to the creation of dark matter, researchers now say.
The universe may be filled with "mirror" particles — and these otherwise-undetectable particles could be shrinking the densest stars in the universe, turning them into black holes.
