In 1789, William Herschel discovered this unique moon around Saturn. 230 years later, its secrets are more promising than ever. Today marks the 230th anniversary of the discovery of Enceladus, one […]
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
The same (former) NASA engineer who previously claimed to violate Newton's laws is now claiming to have made a warp bubble. He didn't.
A few years ago, the first dark matter-free galaxies were announced, and then immediately disputed. Now, there are too many to ignore.
We’ve argued over ideology for far too long. It’s time to pick a better route to prosperity. In every civilized society around the world, there’s a trade-off that must be […]
There are three possible ways we’ll find alien life. With all of these chances, the only question is which will come first. Given everything humanity has learned about the Universe, it […]
It's been precisely 13.8 billion years since the Big Bang occurred. Here's how we know.
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
The intelligent life we are searching for doesn't have to be humanoid.
GPS holds the key, but astronomers can’t do it without help. Since 2019, the night sky — as seen by both human eyes and the telescopes we use to enhance our views of […]
