An international team of astronomers has recently detected two “baby galaxies” using the Webb.
“This baby galaxy shows evidence that its intensive growth is resulting from a merging event of two smaller galaxies assembled early in the history of our Universe,” mentioned theEinstein's gravitational lensing effect produces the two images A and B of the same system.
"Because of Einstein's gravitational lensing or warping effect applied through the JWST, we can see the galaxy twice, like a desert mirage, because light reaches us from two slightly different directions," said Marcin Sawicki at Saint Mary's University in Nova Scotia. The images show a glow attributed to ionized hydrogen gas, providing evidence of the birth of hot, young stars within these young galaxies.
With this new capability, scientists will be able to explore galaxies that formed only a few hundred million years after the Big Bang, marking the cosmic dawn.
