In one sense, light experiences no time during travel, so anytime you are hit by radiation (like from a star) there is frame of reference in which the event was instantaneous.
On the other hand, if you were on Earth and I was in between Earth and Mars, I would receive the data more quickly than you, and I could even watch it whiz by me on its way to you. The thing about relativity is that it’s... relative!
