We review our current understanding of how the first galaxies formed at the end of the cosmic dark ages a few 100 million years after the Big Bang. Modern large telescopes discovered galaxies at redshifts greater than seven, whereas theoretical studies have just reached the degree of ...
"These galaxy observations were among the first set of dat a from the$ 10 billion Webb telescope, which was just launched over a year ago.Unlike Hubble, the bigger and more powerful Webb can see through clouds of dust with its infrared(红外的) vision and discover galaxies previously ...
The detection of such ancient galaxies adds intrigue(神秘色彩) to theories of how the very first galaxies formed, according to astronomers. Were there many large, young galaxies in the early universe that are obscured from astronomers’ view by abundant gases absorbing their light Or were galaxies...
Observations made using large ground-based and space-borne telescopes have probed cosmic history from the present day to a time when the Universe was less than one-tenth of its present age. Earlier still lies the remaining frontier, where the first stars, galaxies and massive black holes formed...

the most common element in the universe, all the way back to the big bang,” he says. “We will be looking back in time to those first moments of the universe, and then watching the universe evolve, understanding how those first stars formed, how the first galaxies formed, and why the...
The image shows the galaxy cluster as it appeared 4.6 billion years ago.Images such as this will help us understand how the first stars and galaxies formed.Some of these may be among the most distant objects known,from the beginning of the universe. The size of a tel...
The discovery of such a rare fossil, led by PhD studentFred Robert and Professor Michael Murphy at Swinburne University of Technology,offers new information about how the first galaxies in the universe formed. 由Swinburne科技大学的博士生Fred Robert和Michael Murphy教授是这种稀有化石的主要发现者,他们提...

Named after Hindu deities, the star streams appear to be the remnants of two galaxies that merged with an early version of the Milky Way between 12 billion and 13 billion years ago when the first galaxies were forming across the cosmos. The structures are so old that the...
