The nature of civilizational threats has changed in a mere decade.
NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.
Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?
When we look at our Sun, its properties are incredibly constant, varying by merely ~0.1% over time. But all stars don't play by those rules.
The crisis of the Anthropocene challenges our traditional narratives and myths about humanity's place in the world. Citizen science can help.
Studies suggest that meditation can quiet the restless brain.
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
The TRAPPIST-1 system is a treasure trove of possibilities and questions. Observations by JWST have just begun.
In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren't close to the same.
In a distant galaxy, a cosmic dance between two supermassive black holes emits periodic flashes of light.
Why do so many cultures celebrate holidays at the same time of year?
The outer planets' clouds hide the weirdness within.
Like humans, stars die. The James Webb Space Telescope's early images already give us a lot of information about how this happens.
Even at its faintest, Venus always outshines every other star and planet that's visible from Earth, and then some!
It's rare that one single image packs so much beauty and science simultaneously. This Hubble view of a nearby star-forming region has both.
“I watched closely for the sun or stars to appear, to correct my chronometer, on the accuracy of which our lives and the success of the journey would depend.”
Despite being the closest planet to the Sun, Mercury "only" reaches 800 °F at its hottest. Venus is always hotter, even at night.
Lithium-ion batteries pose challenges for our transition toward renewable energy. Sodium-sulfur batteries might be a solution.
In 1054, a core-collapse supernova occurred 6500 light-years away. In 2023, JWST imaged the remnant, and might solve a massive mystery.
We are traveling in a realm that once exclusively belonged to the gods. Space travel will force humanity to rethink everything.
