One of our favorite cosmological mysteries is why there is any stuff in the universe. We're here because there was a tiny fraction more matter than antimatter created. We learn about a new observational test for one theory of why that happened, and it has to do with gravitational waves and Q-Balls! Find out what they...

We take a deep dive into toffee planets with The Planetary Guy, Dr. Paul Byrne, who helps us explore the myriad types of exoplanets that might be lurking out there, including some with eggshell crusts and toffee interiors. And gravitational waves have yielded another secret, confirming Stephen Hawking's Black Hole...

On the eve of its long-anticipated launch, we explore one of the many areas of exploration of the JWST, the early universe after the birth of the first stars and the reionization of the interstellar medium. We also take a look at a large comet showing activity beyond the orbit of Uranus, historical trivia, space news...

Scientists are creating large, quantum-fuzzy atomic nuclei with large numbers of neutrons to get clues about nucleosynthesis in the very early universe. Closer to home, the Juno spacecraft has peered hundreds of km below the Jovian cloud tops to better understand its colorful stripy system of bands and zones. And we get...

We explore an exoplanet system where the orbits of the planets are at right angles to each other. A chunk of rock trailing the Earth around the Sun may be a chunk of the Moon, and we take a look at some of the more interesting ways of getting into space and traveling long distances once we're there.
