How to stay safe and prepare yourself for the show of a lifetime! “Nations, like stars, are entitled to eclipse. All is well, provided the light returns and the eclipse […]
Shanghai scientist Ruxin Li has already built the world’s most powerful lasers, and he plans a new one that can rip matter from empty space.
NASA discovers a surprisingly dark planet about 1,400 light years away.
What if alien life — or even intelligence — don’t look like what we’re searching for? When the original Star Trek premiered, it was revolutionary for depicting sentient, intelligent species other than humans, living […]
The pulsar map to Earth was perfect when it was launched. By time aliens get it, it’ll be completely useless. “We [are] a species endowed with hope and perseverance, at […]
Nothing can escape from a black hole… but could another black hole pull something out? Once you fall into the event horizon of a black hole, you can never escape. […]
Black holes shouldn’t be this big, much less this big so many billions of years ago. Yet here we are. “Ultramassive black holes — that is, black holes with masses exceeding 10 billion […]
These scientists scooped up the Nobel by detecting a ripple in space-time.
Here are some of the best books on the rich history, rabid speculations and intriguing fictionalized world of artificial intelligence.
More massive is bigger, less massive is smaller, right? That’s not even half the story. “Billions of years from now our sun, then a distended red giant star, will have reduced […]
The ingredients for life are everywhere, but so far the only life we know of comes from Earth. Here’s how that might change. Ever since human beings first turned our eyes […]
Now we know, on every scale. “There is no such thing as perpetual tranquillity of mind while we live here; because life itself is but motion, and can never be without […]
No other object this large has come so close to Earth in millions of years. In the 5th millennium, we might suffer the consequences. “Honestly, if you’re given the choice […]
And thanks to a new technique and set of observations, we think we know exactly where to find them. At the center of practically every galaxy is a supermassive black hole, […]
Even with nothing new falling into it, our radius is increasing with every second that goes by. It’s no big secret that galaxies grow over time. The force of gravity is […]
If all we had were hydrogen and helium after the Universe were born, we wouldn’t be here today. “The discovery of deuterium and the marked differences in the physical and chemical […]
Scientists at GW School of Engineering and Applied Science develop a prototype solar panel that captures nearly double the amount of energy from light.
Just one equation relates the expansion of space to all the matter and energy we have. If you know this, you can know the fate of the Universe. Last week, […]
Want to be hotter? Add more mass. Want to go even hotter than that? Lose almost all of it. “A candidate is not going to suddenly change once they get into […]
And if their conclusions will be different from ours, how can we be certain we’ve got it right? One of the greatest dangers in all of science is jumping to false […]
LIGO and Virgo reveal a gravitational wave was detected on two different continents. Here’s what that means and why it matters.
Which of these do you think will win out?
If you know when, where and how to look, the show will still be spectacular. “My dad took me out to see a meteor shower when I was a little […]
There’s more to powering the world than releasing energy. When it comes to the ultimate dream of clean, efficient, and prolific energy sources, it’s hard to do better than the […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
Unpredictable winters? Seasons that don’t line up? It’s possible with the right configuration, says physics. “Lord of Light! Come to us in our darkness. We offer you these false gods. Take […]
If the bolide had hit just 30 seconds later, we’d be looking at a very different Earth.
It isn’t just supernovae or neutron star collisions that make the heaviest elements. The physics might surprise you! “Comrades, this man has a nice smile, but he’s got iron teeth.” –Andrei A. […]
Last week, Cassini plunged into Saturn’s atmosphere. Here are the top 6 things we learned from it while it was alive. “Being a scientist and staring immensity and eternity in the […]
