Question

How can astronomers know things for certain since they only look at space from one vantage point?

Answer 1

Even if we observe a space object from only a single viewing angle, we can effectively see it from different vantage points using different observation methods. For instance, we can look at a star using a camera that captures radio waves, microwaves, infrared waves, ultraviolet rays, x-rays, or gamma rays.
