Massive Galaxies Stump Astronomers

I was reading the recent news that the James Webb Space Telescope (JWST) astonished astronomers again. We continue to get big benefits from this relatively new distant telescope.

The latest news involves massive compact galaxies that should not be there if our theories about galaxy formation are valid. The researchers behind this latest finding state the six observed galaxies were from a period about 600 million years after the Big Bang.

Lead researcher Ivo Labbe of Australia’s Swinburne University of Technology said in a statement:

The revelation that massive galaxy formation began extremely early in the history of the universe upends what many of us had thought was settled science…It turns out we found something so unexpected it actually creates problems for science. It calls the whole picture of early galaxy formation into question.

The more we look the more we learn, and the more theories we can toss out the window.
