A DISTANT galaxy with a black hole at its center has spat out radio emissions picked up by an astronomy team in Japan.
Challenges with telescope technologies make this discovery unique.
The oddity, named 3C273, is a quasar at the center of its host galaxy.
A quasar is a black hole anchored in a galaxy, consuming all matter and even light – but 3C273 is still extremely bright.
Located 2.4 billion light-years from Earth, the quasar is the best-studied quasar in the night sky.
The quasar was first observed in 1963 and was the first quasar ever discovered.
Radio telescopes face challenges when focusing on bright objects like 3C273.
Phys.org writes: “When you see a car’s headlight, the blinding brightness makes it difficult to see the darker surroundings. The same thing happens with telescopes when you observe bright objects.”
Researchers at the ALMA observatory developed techniques to study the eclipsed host galaxy.
They found that a structure of radio waves is layered tens of thousands of light-years across the galaxy – the first discovery of its kind.
The radio waves are partly powered by hydrogen gas.
Hydrogen gas is a key component in the formation of stars.
The researchers found that the quasar does little to prevent star formation.
“By applying the same technique to other quasars, we expect to understand how a galaxy evolves through its interaction with the central nucleus,” said a researcher who led the study.
Space observations are on the cusp of significant improvement.
Launched in 2021, the James Webb Telescope recently nestled in its position in space and will be sending colorized images of space back to researchers by July this year.
