Subramanya Chandrashekar was the only one i could get
the connect may be that all of them have an asteroid named after them!

All give their names (at least parts of their names…) to the 4 ‘great observatories’ of NASA:
1. S Chandrasekhar- Chandra X-Ray obs.
2. Arthur Holly Compton- Compton gamma ray obs.
3. Edwin Hubble- Hubble space telescope
5. Lyman Spitzer- Spitzer space telescope….

Clock wise : Chandrashekhar, Arthur Compton, Edwin Hubble, Lyman Spitzer.
All have space telescopes named after them.
I had used Chandra and hubble in a quiz I had done so I knew their faces. The other two, I just went through a list of all space telescopes on wiki named after people.
