The fabric of spacetime is four-dimensional, with three for space and only one for time. But wow, time sure is different from space!
Could life be widespread throughout the cosmos, in the subsurface oceans of ice-covered worlds? NASA's Europa Clipper mission investigates.
An in-depth interview with astronomer Kelsey Johnson, whose new book, Into the Unknown, explores what remains unknown about the Universe.
There are a number of factors to consider when choosing where to build a telescope. These 3 locations, on their merits, surpass all others.
Man seeking meaningful relationship at the intersection of on-demand empathy and Rule 34.
The US needs 28 million EV chargers by 2030. Here’s how it can get there.
The Universe changes remarkably over time, with some entities surviving and others simply decaying away. Is this cosmic evolution at work?
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
Black holes encode information on their surfaces, but evaporate away into Hawking radiation. Is that information preserved, and if so, how?
Artificial intelligence is much more than image generation and smart-sounding chatbots; it's also a Nobel-worthy endeavor rooted in physics!
Watching for changes in the Red Planet’s orbit over time could be new way to detect passing dark matter.
National Geographic's first James Webb Space Telescope book shows us the cosmos like never before.
The earliest Milky Way-like galaxy, REBELS-25, was spotted rotating about its axis. It's only 700 million years old: 5% of our present age.
Astro Mechanica’s “turboelectric” jet engines offer a way to transform both commercial flights and space launches.
Interferometry gave us a black hole's event horizon, but that was in the radio. What can we accomplish with a new optical interferometer?
Hackers are in an arms race with cyber defenders. Will AI tip the balance?
Dinosaurs and other beasts were once thought to be the “undisputed masters” of Venus.
Today, the deepest depths of intergalactic space aren't at absolute zero, but at a chill 2.73 K. How does that temperature change over time?
Physicists recently created Coordinated Lunar Time, a time zone for our Moon.
The Universe has been creating stars for nearly all 13.8 billion years of its history. But those photons can't match the Big Bang's light.
Comet A3, also known as Comet Tsuchinshan-ATLAS, has sprung to life since 2024's last equinox. Here's how to catch the show for yourself.
Are breakthroughs really a matter of chance, or are they simply waiting to be uncovered by the right person at the right time?
Research suggests curiosity triggers parts of the brain associated with anticipation, making answers more rewarding once discovered.
Scientists might be looking for Martian life in the wrong place.
In theory, dark matter is cold, collisionless, and only interacts via gravity. What we see in ultra-diffuse galaxies indicates otherwise.
The Parker Solar Probe is about to undergo its seventh encounter with Venus on its journey toward the Sun. Here's how fast it'll go.
A simple plate of vegetables has found the gaping blindspots in generative AI, and points the way to fixing them.
New evidence suggests the corvid family has surprising mental abilities.
Make Sunsets is bringing solar geoengineering from sci-fi to reality.
In all directions, at great distances, the Universe looks younger, more uniform, and less evolved. Does that mean Earth must be the center?
