Talking Points

Recent interactions between the hosts and their guests.

Our Weird, Wondrous Universe with Erika Hamden
Q: How many galaxies are there?
Erika explains that in the observable universe there are hundreds of billions of galaxies, and the Hubble Ultra Deep Field reveals that nearly every point is a galaxy, highlighting the vastness and richness of the cosmos.
Ruby Raindrops and Painted Peacocks with Munazza Alam
Q: What is the best advice Munazza was given when preparing for college?
Choose a field you enjoy and are good at, maintain breadth to keep options open, and stay curious and willing to learn even as you dive deep into your chosen science.
Ruby Raindrops and Painted Peacocks with Munazza Alam
Q: How far have we gone in space, in terms of human-made objects and exploration?
Humans have reached the Moon, and spacecraft like Voyager 1 have extended our reach well beyond the solar system's planets, totaling billions of miles and approaching the edge of interstellar space, though not anywhere near the next star.
Astrophotography with Astronaut Don Pettit
Q: What is the difference between your first space flight and your most recent one?
Experience and efficiency; later flights are more efficient due to familiarity with the environment, better planning, and understanding how to optimize work, food, sleep, and gear.
Supernovas and Space Gold with Dr. Ashley Villar
Q: How do we know the universe is infinite or finite?
We can measure the age and expansion history to define the observable universe, but whether the entire universe is infinite or finite beyond what we can observe remains uncertain; current intuition leans toward infinite, but there's no definitive proof.
