We’re polluting every corner of our own planet including take our trashy habits out into space with us. Lets learn more about the trash orbiting the planet to the radiation we’re leaking out into space.

May 27th: Rogue Planets
Most of the exoplanets we’ve found are around stars, where they belong. But a few have been found free-floating in interstellar space. How do they form and how can we learn more about them?
May 20th: Elliptical Galaxies
Our galaxy series continues with elliptical galaxies. Unlike other types, these are large, smooth with very few distinguishing features. They’re filled with red and dead stars, a clue to their evolution.
May 13th: Spiral Galaxies
Our galaxy series continues, on to spiral galaxies. In fact, you’re living in one right now, but telescopes show us the various shapes and sizes these galaxies come in
May 6th: Dwarf Galaxies
It’s time to begin a new mini-series. And today @AstronomyCast start with the dwarf galaxies, which flock around larger galaxies like the Milky Way. Are they the building blocks for modern structures?
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.
