Episode 91: Monster Galaxies of the Early Universe, with Henry Joy McCracken

Feature Guest: Henry Joy McCrackenLast month scientists announced the shocking discovery of 574 monster galaxies from the ancient universe. There are surprisingly many such giant galaxies, and they seem to appear more suddenly and earlier than astronomers predicted. How might this finding upend our understanding of galaxy and structure formation in the universe? To help us answer that question we’re joined by the discovery’s co-investigator Henry Joy McCracken.

This episode is dedicated to my wife Denise Fong, on our 6 month anniversary. Denise and I met at the 10th episode celebration of The Star Spot over 3 years ago. It has been a great pleasure to work with you Denise to grow our show and to further public education for astronomy, our common passion. - JustinCurrent in SpaceGalaxies are alive!
