Brian Welch is a PhD student, studying Astronomy, at John Hopkins University.[2] His thesis supervisor, Dan Coe, discovered a very distant galaxy, called The Sunrise Arc, in 2016. That Galaxy was only found because the gravity of a supercluster of galaxies that lie between us and The Sunrise Arc magnified its light, through Gravitational lensing.
Coe assigned Welch the task of examining promising objects within The Sunrise Arc.[2] Because of the COVID 19 epidemic he did much of his work at home, on his laptop.[1]
In June, 2021, Welch published an article in the Bulletin of the American Astronomical Society, announcing the observation of several small, dense globular clusters, within the galaxy.[3]
Meanwhile Welch had found, in 2018, an object now known as Earendel.[2] Welch co-ordinated an international team of Astronomers, who confirmed that Earendel seemed to be a very distant early star. Welch was the lead author of a paper in the prestigious Science journal Nature, announcing the discovery, on March 30, 2022.[4]
Welch played football, in high school, and The Daily Herald reports that, at 6 foot 6 inches, he might be the world's tallest astrophyscist.[1]

Astronomer Dan Coe of Johns Hopkins discovered and named the Sunrise Arc in 2016 as part of a Hubble observation program. Welch, Coe’s student, scrutinized a tiny speck — some kind of object — providentially located on the arc where the magnification was highest. Over the course of 3½ years, the object remained in that spot.”
