Webb’s mysterious little red dots may be hiding entire galaxies
The study says a bright core can outshine a much fainter host galaxy, and researchers found the same pattern in a lower-redshift spiral galaxy.

Since Webb discovered mysterious “little red dots” in 2022, astronomers have struggled to explain them; a galaxy seen 3.3 billion years after the Big Bang may finally reveal their hidden evolution
Science News: Since NASA’s James Webb Space Telescope first revealed mysterious “little red dots” (LRDs) in 2022, astronomers have been racing to understand what th.
In almost all recent images from the depths of space, there are small red dots whose origin has so far been unexplained. Now astronomers have identified a new type of cosmic objects behind it.
Webb’s mysterious little red dots may be hiding entire galaxies
Astronomers may finally have a clue to what happens to the mysterious “little red dots” that crowded the early universe. By studying a spiral galaxy nicknamed the “Saguaro,” researchers found a compact, bright red center that closely resembles these distant objects—but with something Webb usually can’t see around them: a full galaxy. When the team simulated what the Saguaro would look like much farther away, its spiral structure essentially vani…
Webb May Have Found the Family Tree of the Little Red Dots
When the James Webb Space Telescope began finding tiny, intensely red sources in the early universe, astronomers were not looking at ordinary galaxies. The objects were so compact that, in some images, they looked almost like red points of light. They became known as “little red dots,” and their sudden disappearance at later cosmic times […] The post Webb May Have Found the Family Tree of the Little Red Dots appeared first on Curiosmos.
