It seems like every day we learn something new about our Universe. Whether that’s discovering a new set of galaxies or gaining a better idea of how our Universe governs itself, astronomers and scientists of all kinds are constantly improving our knowledge of our cosmic surroundings. To get you up to speed on some of the things the world’s galaxy explorers are up to, we’ve compiled three great talks on galaxies. Watch them all below:
Exploding stars, colliding galaxies and you | Karen Kwitter | TEDxWilliamsCollege
In this talk at TEDxWilliamsCollege, astronomy professor Karen Kwitter gives the low-down on galaxies, space dust, nuclear fusion and planetary nebulae. Watch to build up your astronomy know-how.
How galaxies evolve | Dr. Sarah Sweet | TEDxBrisbane
How does a galaxy evolve? This is what astrophysicist Sarah Sweet studies every day. In this talk at TEDxBrisbane, she explains the fascinating science behind galaxy formation, and her particular subject of study — a galaxy known as a “silver spoon galaxy.”
Upon a dark canvas – the ordered motions of Andromeda’s satellite galaxies | Neil Ibata | TEDxVienna
High school student Neil Ibata worked with his astrophysicist father, Rodrigo Ibata, to research satellite galaxies. In this talk at TEDxVienna, he explains what he learned.
