How the world’s most sensitive yardstick reveals secrets of the universe
When two massive objects – like black holes or neutron stars – merge, they warp space and time. Here's the tool that measures the resulting waves.
How to terraform Mars, without nukes, on a budget
Terraforming Mars has been a dream for decades; here’s how we might get it started today.
For the first time, astronomers have detected a radio signal from the massive explosion of a dying white dwarf
Patience and persistence pays off in ways researchers never expected, allowing them to hear the dying whispers of a distant star.
Astronomers have directly detected a massive exoplanet. The method could transform the search for life beyond Earth.
There are many techniques to search for planets orbiting other stars. Perhaps the simplest of these is called direct imaging, but it's not easy.
NASA’s Habitable Worlds Observatory to finally answer the epic question: “Are we alone?”
The Nancy Roman Telescope is already being built with a goal no smaller than to find inhabited planets beyond Earth.
Why Earth is the only planet with plate tectonics
Here in our Solar System, of all the known planets, only Earth — not Mercury, not Venus, and not Mars — possesses plate tectonics.
Quantum entanglement just got a whole lot weirder
Normally seen with identical particles, entanglement has just been demonstrated between particles with opposite charges.
How Einstein tried to model the shape of the Universe
Two years after proposing his general theory of relativity, Einstein endeavored to find the shape of the Universe.
“Nothing” doesn’t exist. Instead, there is “quantum foam”
Even if you took an empty container devoid of all matter and cooled it to absolute zero, there is still "something" in the container.
