Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won’t last forever.

After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way’s central black hole looks like.
They are expected to be cheaper to build and even more reliable than today’s nuclear plants.
Is the multiverse real? It’s one of the hottest questions in all of theoretical physics. We invited two astrophysicists to join the debate.
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
It is impossible for science to arrive at ultimate truths, but functional truths are good enough.
In the largest star-forming region close to Earth, JWST found hundreds of planetary-mass objects. How do these free-floating planets form?
Although early Earth was a molten hellscape, once it cooled, life arose almost immediately. That original chain of life remains unbroken.
Without wormholes, warp drive, or some type of new matter, energy, or physics, everyone is limited by the speed of light. Or are they?
Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
Our own galaxy, the Milky Way, is both completely normal and absolutely remarkable in a number of ways. Here’s the story of our cosmic home.
The universe’s largest seismometer reveals clues about the Gas Giant’s interior.
“The Expanse” is the best vision I’ve ever seen of a space-faring future that may be just a few generations away.
With the invention of the leap year, the Julian calendar was used worldwide for over 1500 years. Over time, it led only to catastrophe.
Gravitation, all on its own, can reveal what’s present in the cosmos like nothing else.
There is nothing more important to science than its ability to prove ideas wrong.
There are many things that separate science from ideology, politics, philosophy, or religion. Follow these 10 commandments to get it right.
Despite the Sun’s high core temperatures, particles can’t quite overcome their mutual electric repulsion. Good thing for quantum physics!
When the average person has a “theory,” they’re just guessing. But for a scientist, a theory is the pinnacle of what we can achieve.
Known as hypervelocity stars, we originally thought just one would be ejected every 100,000 years. The real number is much greater.
Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. […]
Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.
The European Space Agency’s Solar Orbiter recently captured images that could help scientists better under the mysterious physics of our Sun.
Experts believe they could cut the time it takes a rocket to reach Mars by up to 25%, shaving about two months off the trip.
When the Universe was first born, the ingredients necessary for life were nowhere to be found. Only our “lucky stars” enabled our existence.
The first world that humans should inhabit beyond the Earth is the Moon, not Mars. Here’s why terraforming our lunar neighbor is so appealing.
Are space and time real like atoms are, or is spacetime just a calculational tool? When most of us think about the Universe, we think about the material objects that […]
Speculation about the existence of aliens goes all the way back at least to the Greek philosophers. Their arguments will sound familiar.
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
