I've noticed some people are having issues figuring this out. Don't worry... I did, too.
The first five are simple. I don't think anyone needs any help with this bit, but I may as well put it. For each of the first five, they may be found in each of these areas: -Infinite Cosmos -Astral Heights -Stratos -Abyssal -Unfathomable
Obviously, one for each area.
The sixth one is tricky unless you get curious. There's another area: -Belly Of The Beast
I'd say that should suffice in telling you where it is.
Not obvious enough? You won't die if you're eaten.
Now, what really gets people is the very last one: -Infinity's Midpoint
This one is actually pretty simple, unless you did plenty of traveling. (SPOILER) Remember where the guy was running from? Yeah... That's where.
My advice: Do not travel far to the right. Get all of the hearts EXCEPT for the Stratos heart first (the cloud one). If you get either the Stratos or Belly of The Beast last, it will be very easy to find where you're supposed to go. You'll just have to travel to the left. Also, there is not heart to chase. Just a spot you have to go to.
Thank you SO much for that, sjones25! By the time I gave up and came here to look, I had been flying around looking for the heart for about a half hour. Then, reading the other comments, I went left for another half hour, having gone right through most of the game. I used your trick (holding the left mouse button for ten seconds) and saw I was heading in the right direction. After a few minutes, I tried the mouse button again, and I had passed the island without seeing it. Turns out I was too low. You kept me from having to start over after a few hours playing. I really enjoyed this game. As for the ending, well, it seems a pretty accurate representation of most loves.

Eh...heh... I flew WAY up into infinite cosmos >.< it's going to take me forever to get all the way back down xD I didn't know the last heart was in the beast until I got curious and let it eat me xD
Well, I just finished playing, passing the whole game. It isn't easy, and the thing you really need to know is holding the mouse button for the arrow to show the direction. I doubt that Infinity midpoint is playable without it. The ending it what we should expect.. After all we suffer for love, after losing our dearest (remember the boy was alone in the Infinity midpoint) and after having much persistence, we start once again, and that's the sense and the aim. We carry oue love through generations. And the qualities you need to obtain hearts are quite accurate: curiosity for the first five, courage for the sixth and persistence for the seventh.
