What colors are invisible to humans?

We see our world in a huge variety of colour. However, there are other “colours” that our eyes can't see, beyond red and violet, they are: infrared and ultraviolet. Comparing these pictures, taken in these three “types of light”, the rainbow appears to extend far beyond the visible light.

In addition to ultraviolet and infrared, there are other “colours” which are hidden from sight. The whole set of “colours” is called the electromagnetic spectrum, which is divided into different ranges. In order, from the highest to the lowest energy, they are: gamma rays, X rays, ultraviolet, visible light, infrared, microwaves, radiowaves.

To see the cosmos in light beyond the visible part of the spectrum, special instruments are needed, with different types of detectors depending on the wavelength. These instruments/detectors, allow astronomers to obtain a huge amount of information about the Universe.

In this Space Science Experience, students will match images of astronomical objects to the corresponding wavelength. Nowadays, the European Space Agency has a fleet of satellites that observe the Universe in all the ranges of the electromagnetic spectrum. This is to enable astronomers to obtain a complete picture of the different process that take place around astronomical objects.

The color wheel is a visual representation of color theory, first proposed by Sir Isaac Newton in the 18th century. More a color chart or color scale than anything else, a color wheel shows the relationship colors have to one another. A color wheel is useful for identifying harmonious colors for a particular context. The most common version of a color wheel contains 12 colors based on the red yellow blue (RYB) artistic color model. In this model, the primary colors of red, yellow and blue are placed opposite their complementary secondary colors (green, orange and purple) and next to their tertiary color variations (yellow-orange, red-orange, red-purple, blue-purple, blue-green and yellow-green). Tertiary colors are the colors formed by mixing a primary and secondary color. Many variations of the traditional RYB color wheel concept exist. Another popular color wheel is the red green blue (RGB) or red green violet (RGV) wheel with the colors cyan, magenta, and yellow as secondary.
