Unlike classical galaxies, UFOs emit very little visible light, making them undetectable before. Their intense red color and flattened shape puzzle scientists. Researchers analyzed 56 of these ...

A cosmic object spotted by the James Webb Space Telescope has flummoxed astronomers. Now, a research team has studied hundreds of these "little red dots" and found clues about their identity.

Pictured: a "UFO" (Ultra-red Flattened Object) galaxy as seen in Hubble and Webb images. Emitting precious little visible light, UFOs are all but invisible in Hubble images.

We take a look at how they form and why they're the brightest objects in the universe. Skip to main ... Vicky Fawcett studies red quasars, whose light has been reddened by cosmic dust and which ...

Astronomers have discovered a strange new object in our Milky Way galaxy. The celestial object is emitting X-rays around the same time it's shooting out radio waves.

Astronomers intend to keep investigating the curious red dots. For example, these objects begin appearing in great numbers around 600 million years after the Big Bang, but then plummet in number ...

Interstellar dust consists of tiny solid particles from dying stars' remnants. These particles block visible light, explaining why these galaxies were invisible to the Hubble telescope, which only ...
