Even tyrants and despots offer wisdom worth heeding.
The solar system has some strange stuff in it. Learning how it ended up that way can tell us where we’re going.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
Doctors may be missing fatal illnesses because medical textbooks are biased toward white skin.
Thomas Baldwin’s Airopaidia (1786) includes the earliest sketches of the earth from a balloon.
No matter how controversial or politicized our world becomes, science remains humanity’s best tool for figuring out how things work.
Pandemics have historically given way to social revolution. What will the post-COVID revolution be?
It’s 13.8 billion years old, with an uncertainty of just 1%. Here’s how. How old is the Universe? For generations, people argued over whether the Universe had always existed, whether it […]
Come to grips with the fundamentals of graphic design and master the field’s top tools.
The Crab Nebula goes back to 1054, opening a window into our cosmic past. On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation. A ‘guest star’ […]
Thou shalt not conclude “aliens” from insufficient data. When it comes to what’s out there in this Universe, perhaps the only thing that’s greater than our cosmic ignorance is the […]
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 […]
Catch Saturn at its biggest and brightest, and view its rings while you still can. Right now, in Earth’s skies, Saturn appears at its biggest and brightest. A view of tonight’s […]
It’s one of only five spacecraft that will exit the Solar System, and the only one we have a chance to aim at another star. Of all the spacecraft ever launched, […]
One image can give over 100 times the data we now get from Hubble. NASA’s Hubble Space Telescope, launched in 1990, revealed the previously unseen Universe. The most distant galaxy ever […]
It had long seemed impossible that supermassive black holes could grow to such enormous sizes. But the biggest problem is now solved.
There are many things on large scales that also appear on small scales. But is the Universe truly a fractal? If you take a look at the structures that form in […]
It’s not for climate science and condensed matter physics. It’s for advancing our understanding beyond spherical cows.
In this 1915 map, Lady Liberty shines her light in the West on women in the East, still in electoral darkness
A recent study tested how well the fungi species Cladosporium sphaerospermum blocked cosmic radiation aboard the International Space Station.
Sometimes the value of soft skills feels almost secretive—like some scrap of knowledge handed down through an ancient society of corporate recruiters. Of course, that’s not the case or that’s […]
Just because you have “star” in your name doesn’t mean you are one. When we think about the objects in our Universe, they fall into two categories: self-luminous objects, like stars, […]
Octopuses are known to rapidly change colors during sleep, but it’s still unclear whether they dream like humans do.
Quantum physics isn’t quite magic, but it requires an entirely novel set of rules to make sense of the quantum universe.
Developing an awareness of and an appreciation for science is what we all truly need, not what we’ve been doing.
It’s not just an old superstition — it’s your stressed-out brain.
Ancient corridors below the French capital have served as its ossuary, playground, brewery, and perhaps soon, air conditioning.
Most homes are using insufficient methods to determine when chicken is done cooking and safe to eat.
