I'm trying to remember an old movie title from when I was a kid. I have not been able to get any information. The movie is pre 1980. Is in another planet (maybe Mars, not sure) and there are this creatures that were thin with more than two arms, all ending in disk. If a person looked at them, the aliens will shine a light that will kill you (you will get your eyes burn or a black circle around the eyes). After you die an egg shaped structure will open and drag you inside.
This sounds like Mission Mars with Darren McGavin from 1968. It has an alien which has discs for hand. It also has a big white sphere which opens up and takes in the astronaut after killing him.

And here's the alien:
