Astronomers do not observe every region of the universe or every part of the electromagnetic spectrum with equal coverage, leaving certain gaps in observational astronomy. However, the article suggests that these gaps are fewer than commonly assumed, and the field has made substantial progress in expanding its observational reach across multiple wavelength ranges. The piece addresses a common misconception about the completeness of astronomical surveys.
Why it matters
Understanding which parts of the universe and the electromagnetic spectrum remain underobserved is essential for prioritizing future telescope development and ensuring that scientific blind spots do not lead to systematic biases in our cosmological models.
There are parts of the universe, and of the electromagnetic spectrum, that we’re not covering with our telescopes—but not as many as you might think!
