Double quasars travel through 10 billion years to Earth, about to merge into a monster
A time-lapse image from 10 billion years in the past has just been captured by the Hubble Space Telescope, showing how an incredibly large and powerful cosmic monster was born.
According to Live Science, the two objects NASA's Hubble captured are two very large quasars . A quasar is a bright object that looks like a star when viewed from Earth, but is actually a disguiser.
They are often monster black holes, but not silent and invisible like most black holes, but are violently devouring matter. Gas and dust particles are accelerated by the force of the black hole to nearly the speed of light, glowing brightly.

The light from all the things swallowed together makes the black hole brighter than the light from the entire Milky Way galaxy combined, so it looks like a bright star despite being very far away from us.
The double quasar that NASA captured has a record distance: 10 billion light years.
Scientists have hypothesized that such extremely bright quasars are a sign of the early universe, but the "twin" nature of the objects makes them particularly interesting.
According to astronomer Yu-Ching Chen from the University of Illinois at Urbana-Champaign (USA), the lead author of the study just published in Nature about the two strange quasars, they are an extremely rare pair in the early universe.
They considered the possibility that they were just an optical illusion, the Hubble telescope accidentally looking through a region of space-time warped by the gravity of some massive object. But no, they were actually twins - another observation from the W.M. Keck Observatory in Hawaii confirmed.

Not only are they rare quasar binary stars, they are also in the process of merging with each other. The merger would certainly create a brilliant black hole collision, releasing enormous amounts of energy and resulting in a monster black hole.
More specifically, the images provided by Hubble or MW Keck are not images of the present, but rather a timeless gift from 10 billion years ago . An object 10 billion light years away from us means that the light from it must travel through space-time for 10 billion years to reach an Earthling's device.
In other words, this extraordinary discovery has given us a direct image of a rare monster from the dawn of the universe. It is possible that they have merged long ago in the present, and it is also uncertain whether the monster born from that merger still exists.
