ScienceSpaceAstronomers stunned after James Webb Space Telescope discovers the earliest pair of black hole-powered quasars
The James Webb Space Telescope has found the oldest pair of quasars ever seen, and scientists say they shouldn't exist yet at that point in the universe's history.
Using the James Webb Space Telescope, astronomers have discovered the oldest pair of black hole-powered quasars ever seen. There's just one problem: they shouldn't exist!
Astronomers using the James Webb Space Telescope discovered the oldest and most distant pair of quasars ever found, dating to just 900 million years after the Big Bang.
The pair, nicknamed Nāpōwawāʻenakaulua, contains black holes 1.5 billion and 400 million times the mass of the sun, separated by just 18,100 light-years.
Research team leader Silvia Onorato said there is no definitive theoretical explanation for how these giant quasars grew so massive so early in the universe's history.
No practical action needed, but the research team leader says there is no current theoretical explanation for how even one of these giant quasars exists so early, let alone two.
