   Aug 21, 2019 · This is a Hubble Space Telescope image of galaxy SDSS J1226+2152, which is being magnified and distorted by the immense gravity of a galaxy cluster in front of it. It is one of four distant, star-forming galaxies the TEMPLATES team will study with Webb. The team chose it as an example of a galaxy that is not very dusty.

   Are galaxies forming when the universe was only 400 million years old?

   • Researchers analyzing data from NASA’s James Webb Space Telescope have pinpointed three galaxies that may be actively forming when the universe was only 400 to 600 million years old. Webb’s data shows these galaxies are surrounded by gas that the researchers suspect to be almost purely hydrogen and helium, the earliest elements to exist in […]

   Why do new galaxies appear every year?

   • As the universe ages, it's harder and harder for material to clump together to form new galaxies and drive continued star formation. In fact, the peak of star formation passed billions of years ago. While new galaxies continue to light up, the rate of emergence is slowing down, with fewer and fewer new galaxies appearing every year.

   Are there any new galaxies?

   • So, in many senses, no new galaxies appear today. The process of building them — of seeding them as tiny differences in density or the initial gathering of dark matter — is over and done with, an act that took place in the ancient cosmos and never again.

   Why are there no new galaxies today?

   • As the regular matter gathered, it compressed, fragmented and gave light to the first stars. These protogalaxies went on to consume more gas, merge with neighbors and grow to become the fully formed galaxies we see today. So, in many senses, no new galaxies appear today.

   Could a massive object change how we think about galaxies?

   • The objects are so massive, that if confirmed, they could change how we think of the origins of galaxies. The findings, published Wednesday in Nature, use data from the James Webb Space Telescope ’s infrared-sensing instruments to picture what the universe looked like 13.5 billion years ago—a time when it was just 3 percent of its current age.

   Could six massive galaxies change how we think of the origins?

   • Image processing: G.
