The universe as never seen before: this week in space

The Eagle Nebula

Space telescopes provide stunning images of the universe, thanks to a combination of advanced technologies and observations made outside the constraints imposed by our atmosphere. However, due to physical limitations, each telescope can only observe a specific type of electromagnetic radiation, or a relatively narrow range of it, thus limiting our ability to gather all … Read more

Here’s how you might get incredibly large galaxies in the early universe

Universo Oggi

One of the most interesting (and puzzling) discoveries made by the James Webb Space Telescope (JWST) is the existence of “incredibly large galaxies”. As noted in a previous article, these galaxies existed during the “cosmic dawn,” the period that coincided with the end of the “cosmic dark age” (about 1 billion years after the Big … Read more
