Massive disk galaxy could change our understanding of how galaxies are born
By Chelsea Gohd published
A massive, rotating disk galaxy that first formed just 1.5 billion years after the Big Bang, could upend our understanding of galaxy formation, scientists suggest in a new study.
![This radio image shows two jets shooting out of the center of Cygnus A, a galaxy not too far from our own. A new paper reports discovering a similar object in a much more distant, ancient galaxy. That galaxy has a bright, relatavistic jet emanating from its central supermassive black hole pointed at Earth, making it a blazar.](https://cdn.mos.cms.futurecdn.net/AinMqAgYaMhRccnwjnFaBg-320-80.jpg)
The universe may have been filled with supermassive black holes at the dawn of time
By Rafi Letzter published
As the universe cooled in the era after the Big Bang, a supermassive black hole had already formed in the center of a galaxy, forming a giant engine of energy we can still see today.
