If anyone wants to find Hercules X-1, it&#x27;s at these coordinates: RA 16 57 49.83, dec +35 20 32.6. It&#x27;s also magnitude 13, not visible to the naked eye (about 0.00064% as bright as Vega, which it is fairly close to.)<p>Also, one reason why the scientist mentioned in the article didn&#x27;t look at his star is because he couldn&#x27;t know where it is. We can guess that the graduate student in question was Ethan J Schreier, who was in the MIT area until 1973, and the position of X-1 wasn&#x27;t known until 1973, three years after the launch of the satellite. On the other hand, if I was that scientist, I would still have looked in general at the Hercules constellation, out of pure curiosity.<p>(The scientist in question certainly isn&#x27;t Gursky, as he was a graduate student decades prior, but certainly also could&#x27;ve been Harvey Tananbaum. I had no information on been R. Levinson, Edwin M. Kellogg, and Giacconi [0] was a student at the University of Milan in the 40s.)<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Riccardo_Giacconi" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Riccardo_Giacconi</a>
