Astronomers Made A Family Tree For The Stars In Our Galaxy
By studying the chemical makeup of stars, researchers have made a "family tree" for our sun and other stellar bodies. Why Are Most Galaxies Spiral-Shaped? - https://youtu.be/aIUu5uMKB70...
========== Hey everyone, Trace here. A Biologist and an Astronomer go to dinner. That’s not the start of a joke, but it is
actually how that astronomer got the inspiration for a new way of thinking about the stars. That astronomer was the University of Cambridge’s
Dr. Paula Jofré, and she realized that she could chart stars in the milky way the same
way we chart the family tree of animal species. She and a team picked 22 stars (including
our sun) and observed their chemical makeup, their age, and their movement to plot them
on a stellar “tree of life.” They found that the stars they looked at could
be plotted on three branches of the tree, with a few miscellaneous ones that didn’t
fit with the others. They can tell which stars are related based
on their chemica...
