A quote from a 1995 book by astronomer Carl Sagan describes a world many find disturbingly similar to ours.
The difference between predictions and observations of the magnetic properties of muons suggests a mystery for the Standard Model.
Why would the Earth suddenly start vomiting forth huge quantities of mud?
Though a single measurement is not enough to definitively decide the debate, this is a major win for dark matter proponents.
Quantum mechanics has taught us that even empty space contains energy. “Negative energy” is the state of having less energy than empty space.
2023 will see the launch of new rockets, the return of OSIRIS-REx, and a mission to Jupiter that could help us find extraterrestrial life.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
In 2020, scientists took more than a kilo of moon rock and soil back to Earth for testing.
“A modern five-day forecast is as accurate as a one-day forecast in 1980.”
It’s like radar, but with light. Distributed acoustic sensing — DAS — picks up tremors from volcanoes, quaking ice and deep-sea faults, as well as traffic rumbles and whale calls.
As far as we know, it’s only happened once to one unlucky person in Oklahoma.
Dead whales inspire a way to find extraterrestrial life on Mars.
Hawaii is the most isolated volcanic hot spot on Earth, far away from any plate boundary.
Maybe bring an umbrella just in case.
Perhaps wormholes will no longer be relegated to the realm of science fiction.
The answer to this question is key to understanding why anything exists.
Maybe the brain isn’t “classical” after all.
It’s on a 100,000-year timescale, though, so the next few centuries might not be so comfortable.
There’s the textbook answer, then there’s the real answer.
From astrobiology to geology, a Moon base could serve as a laboratory unlike anything on Earth.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
Methane is a shorter-lived but more potent greenhouse gas than carbon dioxide. Cleaning it up could have a quick impact on global warming.
Astronomers have been looking for radio waves sent by a distant civilization for more than 60 years.
Maybe our understanding of quantum entanglement is incomplete, or maybe there is something fundamentally unique about consciousness.
There are at least 15 different types of solid water (ice). Now, scientists believe that there might be a second type of liquid water.
We know the Universe is expanding, but scientists don’t agree on the rate. This is a legitimate problem.
Does it have a deeper significance — or is it just a number?
The stars circle each other every 51 minutes, confirming a decades-old prediction.
The DART mission tested whether it’s possible to deflect an asteroid by crashing something into it.
