ESO observations reveal black holes' breakfast at the cosmic dawn

Astronomers have observed reservoirs of cool gas around some of the earliest galaxies in the universe. These gas halos are the perfect food for supermassive black holes at the center of these galaxies, which are now seen as they were over 12.5 billion years ago. This food storage might explain how these cosmic monsters grew so fast during a period in the universe's history known as the Cosmic Dawn.

That raises a question that has vexed biologists: why the disparity? No one knows the answer, but by comparing bone growth across newborn bears, dogs and other animals, scientists find that one idea doesn't hold up.
