- Although we know a tremendous amount about galaxies, we're still trying to figure out a significant number of details about how they formed and grew up.
- Through a combination of observations across many wavelengths, but especially with ALMA and, soon, with the James Webb Space Telescope, we're learning a tremendous amount of new information.
- Learn all about how we know what we do today, and how we hope to push back the frontiers of knowledge even further, on this edition of the Starts With A Bang podcast!
Have you ever wondered how it is that we know all we do about galaxies? How they formed, what they’re made of, how we can be certain they contain dark matter, and how they grew up in the context of the expanding Universe? In any scientific discipline, we have the things we know and can be quite confident in, the things that we think we’ve figured out but more data is required to be certain, and the things that remain undecided given the current evidence: things over the horizon of the present frontiers.
Fortunately, we have the ability to scrupulously identify which aspects of galaxy formation and evolution fall into each category, and to walk right up to the edge of our knowledge and peer over that ever-expanding horizon. Joining me for this episode of the Starts With A Bang podcast is scientist Arianna Long, Ph.D. candidate at the University of California at Irvine and soon-to-be Hubble Fellow at the University of Texas at Austin. With the advent of ALMA and the James Webb Space Telescope, in particular, we’re poised to seriously push back the frontiers of the unknown, and you can get the insider’s view of exactly what we’ll be looking for and how.
