In a far-reaching discovery with astrophysicist Karolina Garcia, we discuss what's in the Universe and how it grew up.
What do the dark recesses of the early Universe and Zelda: Tears of the Kingdom have in common? More than you could have ever hoped for.
The brightest gamma-ray burst ever observed, GRB 221009A behaved in unexpected ways that might help us understand how they occur.
Neuroscientist and author Bobby Azarian explores the idea that the Universe is a self-organizing system that evolves and learns.
There are 40 billion billion black holes in the universe. Here’s how our Solar System stacks up against ten of them.
We don't know what causes Miyake events, but these great surges of energy can help us understand the past — while posing a threat to our future.
Exoplanet LP 791-18d is likely to have an atmosphere and liquid water.
There is no such thing as a void in the Universe.
Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Recreating them in the lab is not easy.
Hubble showed us what our modern day Universe looks like. JWST's big goal was to teach us how the Universe grew up. Here's where we are now.
With no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.
The outer planets' clouds hide the weirdness within.
There are two methods to measure the expansion rate of the Universe. The results do not agree with each other, and this is a big problem.
In 1974, Hawking showed that black holes aren't stable, but emit radiation and decay. Nearly 50 years later, it isn't just for black holes.
The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?
If our Universe were born a little differently, there wouldn't have been any planets, stars, galaxies, or chemically interesting reactions.
"Superhabitable" planets might be real, but Earth is probably as good as it gets.
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
Does humanity have a moral imperative to seed life on lifeless worlds? And should we avoid colonizing a planet if life already exists there?
Einstein's most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.
