Think they all burn through their fuel, die, and leave white dwarfs, neutron stars, or black holes behind? Think again. The day will come when our Sun, like most stars, can […]
If you don't mourn in North Korea, you risk being executed.
China has reached a new record for nuclear fusion at 120 million degrees Celsius.
With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.
Ancient corridors below the French capital have served as its ossuary, playground, brewery, and perhaps soon, air conditioning.
The U.S. has the world's largest debt in absolute terms, but Japan's is the largest when measured in terms of its debt-to-GDP ratio.
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where's everyone else?
Infrared, visible, and ultraviolet combine to show us Jupiter’s features as never before. The largest planet in our Solar System, Jupiter, is our own ‘failed star.’ The best evidence-based classification scheme […]
It’s one of Einstein’s most bizarre predictions. And it’s true. There’s no such thing as absolute time. No matter where you are, how fast you’re moving, or how strong the gravitational […]
The center of our Sun tops out at 15 million K, but nuclear bombs can get nearly 20 times hotter. Here’s how. In terms of raw energy output, nothing on our […]
With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.
There are three factors all competing to determine the fate of the Earth, and the one that’s winning now won’t win in the end. If you could measure the average distance […]
For the cosmos, it’s all too easy being green. Stars come in a wide variety of colors, but never green. Stars form in a wide variety of sizes, colors and masses, […]
Despite all that we've learned about the Universe, there remain unanswered, and possibly unanswerable, questions. Could "God" be the answer?
We've only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.
Musical preferences are correlated with personality traits. This connection exists across cultures and continents.
We’re still not sure what the ultimate question is. Here are 5 excellent candidates. One of the most amusing stories in all of science fiction is Douglas Adams’ The Hitchhiker’s […]
Be more like Goldilocks.
Only 17 years after its discovery have we learned we’re safe from asteroid Apophis. Ever since its 2004 discovery, asteroid 99942 Apophis has threatened planet Earth. Asteroid Apophis has been measured […]
When people pick the greatest scientist of all-time, Newton and Einstein always come up. Perhaps they should name Johannes Kepler, instead.
The recently discovered Oort cloud comet, Bernardinelli–Bernstein, has the largest known nucleus: 119 km. Here's what it could do to Earth.
Avi Loeb says it’s aliens. Every other astronomer disagrees. Here’s why. In 2017, an astronomical event occurred that was unlike any other: for the first time, we observed an object that […]
Bring not a bagpipe to a man in trouble.
The sky is blue. The oceans are blue. While science can explain them both, the reasons for each are entirely different.
In 2020, we experienced the shortest ‘day’ in 50 years. Here’s the reason why. On the timescales that humans experience, there are lots of things that we consider to be extremely […]
