It's also not clear why they included a picture of him playing guitar with a caption about his band...
There is a bit of a push at the moment, and has been for a while, to show that scientists and other technical types are normal people too, not just the stereotype anal retentive hyper-dedicated socially disconnected Asperger afflicted geniuses. You'll often see a little bit of information about the people in question that is ultimately completely irrelevant to the science/tech being discussed.
If it does help break down the stereotype a bit then it is a good thing: many kids are put off science in part because of such things.
"the political people who are nimble in the art of writing government grants have gradually displaced the eccentric and idiosyncratic people who typically make the best scientists. The eccentric university professor is a species that is going extinct fast"
People like to just believe that brilliance is only possible at random, and nothing they can do will help, unless they get lucky.
It's the same reason the lottery still exists.
On the other hand, scientists (especially observational scientists) know that there's many many many brilliant scientists in the world, and which one of us actually happens to do the right kind of scan on the right data at the right time can be down to pure, "dumb" luck.

People seem to think that the Dunning-Kruger effect means "smart people think they're dumb and dumb people think they're smart!" but I don't think that's very accurate.
What they actually found was that lower-skilled people thought their skill level was somewhat higher, and higher-skilled people thought their skill level was a little lower, but not to the point where their relative perceived skill levels inverted. At no point along the skill curve did people incorrectly perceive themselves to be higher or lower in skill level in comparison others who were actually higher or lower in skill. The perceived skill curve was a little less steep than it should have been, that's all.
I think a more appropriate cognitive bias would be the curse of knowledge: https://en.wikipedia.org/wiki/Curse_of_knowledge
Hard to believe that an undergraduate at the time would have "his team". He was probably the part of a larger team that gave the undergrads the opportunity to look at the images generated by the equipment, and he was the student who found the evidence. Not saying that he shouldn't be given credit.
