Astronomers Spot Six Massive Galaxies

A handful of objects were determined in James Webb Space Telescope (JWST ) and are estimated to be from more than 12 billion years ago, only 500 to 700 million years after the Big Bang reaching sizes up to 100 billion times the mass of our sun, according to a media report on Thursday.

According to reports, the objects found are six galaxies, too big to even exist within the current models, and is expected to transform the understanding of the earliest galaxies formed in the universe.

The powerful space telescope studies the Universe in infrared, perfect for spotting the light that has travelled for billions of years and one of its main objectives is to peer farther into that space-time than any instrument before.

Commenting on the observation, astronomer Joel Leja of Pennsylvania State University said, we looked into the early universe and had no idea about the findings, but have succeeded to found something so unexpected that its likely to create problems in science, as it challenges the whole picture of the galaxy formation.

There are numerous reasons the fully formed galaxies pose a problem, one is the density of matter within today's largest galaxies that exceeds vastly and estimates for this time period. Another is the density of normal matter coming into tension with the amount of dark matter in the haloes of these galaxies.

The explanation of objects seems difficult under current cosmology, making the research team busy scouring their work for errors. 

So far, the data and the team's interpretation of it have remained solid and have suggested there is one of two things wrong, our understanding of cosmology, or our understanding of galaxy formation in the early Universe. 

Leja added the found objects are informally called, 'Universe breakers' for now and they have been living up to their name so far.
