Unidentified Flying Objects, or UFOs, have intrigued humans for decades. Now and then someone spots something strange in the sky and believes it to be extra-terrestrial. However, there is a kind of UFO that has only recently been seen in space. These are “UFO galaxies” that are a mystery to humans.

UFO galaxies are big, red and really dusty and can only be seen in infrared light, with NASA’s James Webb Space Telescope (JWST) first to spot them in deep space.

This is why they were only discovered recently. They appear similar in size and shape to other galaxies but have never been caught on other telescopes, such as the Hubble. Scientists wanted to figure out more about these galaxies and why they were so red and dusty.
