Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Originally, the abundance of bright, early galaxies shocked astronomers. After 3 years of JWST, we now know what's really going on.
Kathryn Harkup, chemist and author of V Is for Venom, joins Big Think to discuss why Christie isn’t just a brilliant writer but a unique science communicator.
In just its first 10 hours of observations, the Vera Rubin observatory discovered more than 2000 new asteroids. What else will it teach us?
For over 50 years, it’s been the scientifically accepted theory describing the origin of the Universe. It’s time we all learned its truths.
Evolution may have built our brains, but it didn't build them to find truth.
For hundreds of millions of years, a cosmic fog blocked all signs of starlight. At last, JWST found the galaxies that cleared that fog away.
Here in 2025, many of us claim to come to our own conclusions by doing our own research. Here's why we're mostly deluding ourselves.
As the closest icy ocean world to
Earth, Ceres may be a promising candidate in the search for signs of ancient life.

We may be close to finding life beyond Earth. But would we even recognize it if we did? Astrobiologist Betül Kaçar explains what signs NASA is looking for.
Massive galaxy cluster Abell S1063, 4.5 billion light-years away, bends and distorts the space nearby. Here's what a JWST deep field shows.
Is the Universe's expansion rate 67 km/s/Mpc, 73 km/s/Mpc, or somewhere in between? The Hubble tension is real and not so easy to resolve.
The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims "parallel Universes," but is that right?
Different methods of measuring the Universe's expansion rate yield high-precision, incompatible answers. But is the problem robustly real?
"The rise of the internet brought about similar fears, yet it ultimately made learning richer and more accessible."
Launched in March, the PUNCH mission has viewed two incredible coronal mass ejections, tracking them farther from the Sun than ever before.
Annie Duke, a poker champion turned decision scientist, talks with Big Think about how to choose well under uncertainty.
The tiniest galaxies of all are the most severely dominated by dark matter. Could black holes be the cause of the extra gravity instead?
A few physical quantities, in all laboratory experiments, are always conserved: including energy. But for the entire Universe? Not so much.
For his new book, “The Ghost Lab,” Matt Hongoltz-Hetling spent time with paranormal investigators to understand their relationship with science and society.

"If we did create beings that were more like non-human animals, we ought to treat them much better than we now treat non-human animals."
