The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we’re woefully unprepared.
Does it have a deeper significance — or is it just a number?
In 1974, Stephen Hawking showed that even black holes don’t live forever, but emit radiation and eventually evaporate. Here’s how.
In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.
Our understanding always will remain incomplete.
If you want to share the truths about our Universe with others, don’t fall into the trap of arguing with a misinformer. Do this instead.
The stars circle each other every 51 minutes, confirming a decades-old prediction.
Most exoplanets have been found around single stars via the transit method. But binary star systems might contain even more of them.
Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.
Early relics and late-time objects give incompatible results for the expanding Universe. This independent anomaly intensifies the problem.
The DART mission tested whether it’s possible to deflect an asteroid by crashing something into it.
“Even with my training, I still got insights from the book’s descriptions. That’s how good Carroll is at explaining physics.”
Are you unhappy with how various events in your life turned out? Perhaps, in a parallel Universe, things worked out very differently.
The Universe gravitates so that normal matter and General Relativity alone can’t explain it. Here’s why dark matter beats modified gravity.
Unfortunately, the Lunar Ark project is an idea more at home in science fiction than science fact.
1.9 billion years ago, a star’s explosive death created a black hole. Its light just arrived at Earth. But did it set a cosmic record?
“To take this in, you need to ride inside the mathematical symbols.”
Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?
Before we formed stars, atoms, elements, or even got rid of our antimatter, the Big Bang made neutrinos. And we finally found them.
NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.
Over the past 50 years, 27 leap seconds have been added to our time.
With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.
The Universe begins with negligible amounts of angular momentum, which is always conserved. So why do planets, stars, and galaxies all spin?
Uncertainty is inherent to our Universe.
From time-traveling billiard balls to information-destroying black holes, the world’s got plenty of puzzles that are hard to wrap your head around.
It’s the very closest stars to us that hold the key to unlocking the possibilities for life in star systems all throughout the Universe.
In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.
This technological feat changes our cosmic history.
