Apr 29th: Understanding the Ages of Distant Cosmic Objects
How old is that star? That planet? That nebula? Figuring out the ages of astronomical objects is surprisingly challenging. Fortunately, astronomers have developed a series of techniques they can use to work out the ages of stuff.
Apr 22nd: The God**** Particle – Remembering Peter Higgs
Last week, we learned about the death of Peter Higgs, a physicist and discoverer of the particle that bears his name. The Large Hadron Collider was built to find and describe the particle. Today, we’ll look back at the life of Peter Higgs and his particle.
Apr 15th: Einstein’s Theory of Special Relativity
It’s all relative. How many times have you heard that? Well, when you’re traveling close to the speed of light, everything really is relative; especially the passage of time. This week, Fraser and Pamela give you the skinny on Einstein’s Special Theory of Relativity
Apr 8th: Total Eclipse of the Science: Experiments During the Eclipse
How to watch a solar eclipse and do some science! The next great eclipse is upon us, with viewers across North America. It’s an amazing experience, but also an opportunity to do science. Let’s talk about what we can learn from this momentous event.
Apr 1st: Orbital Resonances
Several of the planets and moons in the Solar System are in orbital resonance, orbiting in a geometric lockstep. And not just the Solar System, astronomers have found the same resonances in other star systems.
Mar 25th: Solar System Volcanoes
The Solar System is more volcanically active than we thought. Today, we’ll explore volcanism on other worlds.
Mar 18th: How Peer Review Fails
You’ve probably heard that the best kind of science is peer-reviewed research published in a prestigious journal. But peer review has problems of its own. We’ll talk about that today.
Mar 11th: NASA Innovative Advanced Concepts (NIAC)
NASA works on many missions using tried and true technology, but they also invest in creative ideas that could drive the future of space exploration. It’s called NASA’s Innovative Advanced Concepts or NIAC.
Mar 4th: NASA’s Commercial Lunar Payload Services (CLPS) Program
As more commercial companies are targeting the Moon, NASA is working with partners to deliver its payloads to the lunar surface. Today let’s talk about NASA’s Commercial Lunar Payload Program.
