Alien Life Might Be Purple In Color And Not Green: Study

The study suggests that although aliens might live on a world similar to Earth, it would not be as green as ours. Aliens may have various colors because they can be entirely different.

Because they would be covered in bacteria, scientists think that aliens could be purple in color. They also believe that there may be very little or no visible light on their planet.

The latest study detected light signals that originate from worlds devoid of oxygen and sunlight, such as many of the exoplanets that have been detected to date. According to research, green is the predominant color that indicates the presence of life on Earth because green chlorophyll helps bacteria and plants convert sunlight into energy.

If the species on the planet run their metabolisms on other infrared light, they should be able to survive while it revolves around a smaller and fainter star. Interestingly, infrared-powered bacteria can be found in a variety of earthly settings, particularly in places like murky marshes and deep-sea hydrothermal vents where sunlight cannot reach them.

The scientists said that while the possibility of life—or purple bacteria—evolving on other worlds is unclear, purple may become the new green in the hunt for surface life.
