The Milky Way may be surrounded by 'too many' mini galaxies, new discoveries revealAstronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.

'The early universe is nothing like we expected': James Webb telescope reveals 'new understanding' of how galaxies formed at cosmic dawnAstronomers using the James Webb Space Telescope have observed five extremely dense proto-globular clusters along a hair-thin arc of glittering stars. The discovery could help them understand how the earliest galaxies formed.
