Why don't NASA space crafts capture images of the universe in color?
We only see light in a very narrow range of the spectrum. Satellite images "see" a lot more.
The electromagnetic spectrum is much larger than what our eyes can see, and many objects in space are best observed at frequencies that are invisible to the human eye.
The amazing images we see are created by artificially coloring and superimposing a number of monochrome images that are taken by satellites using various filters to select light frequencies.
The majority of images use synthetic colors to represent wavelengths that are not really visible to us.

NASA space crafts typically capture images of the universe in black and white or grayscale rather than color because the primary purpose of these images is scientific analysis. Grayscale images are often more useful for analyzing features such as brightness, contrast, and texture, which provide valuable data for scientific research. Additionally, capturing and transmitting color images requires more complex and expensive equipment, as well as increased data storage and transmission capacity, which may not always be feasible or necessary for the scientific objectives of a particular mission.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
