Dark Matter Research finds 21.000 New Galaxies!

Astronomers working on a massive attempt to finally uncover the secrets of dark energy made a surprising discovery along the way.

While they were mapping the universe as part of the Dark Energy Survey, an international team of researchers spotted nearly 21,000 extremely-dim galaxies hiding in plain sight, according to The distant objects, known as low-surface-brightness galaxies (LSBG), are particularly hard to find, so this treasure trove of new data could be a priceless tool in figuring out how they form and why.

While scientists estimate that these LSBGs make up roughly 15 percent of all the baryonic matter — that’s anything we can see and touch — in the universe, they’re still poorly understood. That’s because they can be dimmer than the surrounding night sky, making them particularly easy to overlook.

But now that the astronomers have found so many of these galaxies, they expect future models of galaxy formation — and even upcoming attempts to survey the sky — to be far more accurate than existing models, according to research shared online last week.
