A research team led by Shuo Huang has observed a massive and extremely active barred spiral galaxy in the early universe with ALMA and the James Webb Space Telescope .

They found that compared to modern galaxies, this monster galaxy has important similarities in shape and differences in the gas motion.

This discovery improves our understanding of how barred spiral galaxies, like our own Milky Way , grow and evolve.

The gas disk has a diameter of about 120,000 light years , which is twice the diameter of the main body of the galaxy visible as stars.

It was created from a large amount of gas that is spiraling towards the galaxy from the cosmic web.

"This is a new picture of a monster galaxy, in which a disk galaxy is formed from a cosmic-scale gas flow," says Shuo Huang .
