If this newfound galaxy is just the tip of the iceberg, the entire Universe may fall into place.
smaller-protogalaxies shows how it should be obscured by dust during the most rapid phases of star-formation. For the first time, a team of astronomers may have discovered the missing link between the earliest and the later, more massive galaxies that we see.One of the greatest challenges for a scientist is that every time you make a new advance, it only raises more questions. When we look out at our Universe today, we see galaxies with all sorts of different properties.
web to galaxy clusters to individual galaxies, all require dark matter to explain what we observe. The large scale structure requires it, but the seeds of that structure, from the Cosmic Microwave Background, require it too.As the Universe expands and cools, the regions that have slightly more matter than others will begin to preferentially attract more and more of the matter from surrounding regions towards it.
After a total of 550 million years, the Universe finally becomes fully reionized, and light can freely travel without being absorbed. Yet we continue to see only these bright but low-mass galaxies for some time, until about a billion years after the Big Bang, when enormous galaxies even more massive than our Milky Way appear in our telescopes. The big puzzle here is the missing link between these two populations.
imaged at high resolution and in multiple instruments, even without next-generation technology. This galaxy's light comes to us from 530 million years after the Big Bang, but the stars within it are at least 280 million years old. How we go from tiny galaxies like this to the massive ones we see a few hundred million years later is a mystery in galaxy evolution.
