Scientists reveal the discovery of merging massive black holes from the early universe using the Webb telescope.

• A new discovery of the earliest known merger of black holes has been made by the Webb Space Telescope.
• The black hole with a mass of 50 million times that of the sun is one of the black holes involved, while the other one has a similar mass but is obscured by dense gas.
• The research indicates that mergers are crucial in the accelerated expansion of black holes.

The Webb Space Telescope has discovered the earliest known merger of black holes.

Scientists reported that the two gigantic black holes and their galaxies merged just 740 million years after the Big Bang, making it the most distant detection of merging black holes ever.

Our sun is 50 million times less massive than one black hole, while the other is believed to be similar in size but is concealed in thick gas, making it challenging to detect.

Now, astronomers are uncertain about the origin of supermassive black holes' immense size.

According to a study published in the Monthly Notices of the Royal Astronomical Society, mergers are the primary way black holes grow rapidly, even at the beginning of the universe, said lead author Hannah Ubler of the University of Cambridge.

From the start of galaxy formation, black holes have played a crucial role, according to Ubler.

The Webb Space Telescope, launched in 2021 as the successor to NASA's Hubble Space Telescope, is the largest and most powerful observatory ever sent into space. It is a joint U.S.-European project that surveys the universe from a location 1 million miles from Earth using infrared technology.
