The central region has been given the name «Spiderweb» though it was previously known as MRC 1138 - 262, because it seems to consist of tiny galaxies trapped by gravity, rather like flies in a spider's web.

New observations show that tiny galaxies in the early universe could have triggered the epoch of reionization — a period when harsh radiation tore apart hydrogen atoms — which astronomers consider key to understanding how stars and galaxies arose from the universe's early dark void.

First proposed 6 years ago, this notion maintains that tiny galaxies, not massive ones, should arise last because it takes gravity so long to assemble the sparse bits of matter in voids.

While a typical galaxy contains billions of stars, a number of tiny galaxies have been found in recent years that do not fit the classic picture and instead resemble the groups of stars known as star clusters.

Because dwarf galaxies contain so few stars, this suggests that whatever is responsible for FRB 121102 has a better chance of forming in tiny galaxies than large, spiral ones.

As a result, moving in, around, and through such a tiny galaxy is quite easy to do, making them far more likely to be filled with streams and outflows of speedy charged particles known as galactic winds, which can flood such galaxies with little effort.

Astronomers have discovered something equally puzzling while surveying a group of tiny galaxies that neighbor the Milky Way: No matter how many stars they contain, every galaxy has the same mass.

An international team of astronomers, led by Hakim Atek of the Ecole Polytechnique Fédérale de Lausanne, Switzerland, has discovered over 250 tiny galaxies that existed only 600 - 900 million years after the Big Bang [1]-- one of the largest samples of dwarf galaxies yet to be discovered at these epochs.

Although this may seem low, Zitrin said that given its small size and low mass, the tiny galaxy is in fact rapidly evolving and efficiently forming stars.

Thuan said the data indicates that the tiny galaxy is rapidly producing new stars at a quarter of the rate of the Milky Way — yet its mass in stars is 30,000 times smaller.

«It is rare for such a tiny galaxy to still contain gas and be forming stars when it is in close proximity to a much larger galaxy, so this is a great opportunity to see just how this process works.

And if, as current models suggest, the universe should be teeming with very small halos of it, then where are all the tiny galaxies?

My opinion is that the cleanest sites are the teeniest, tiniest galaxies we know about — dwarf galaxies.

Their low metallicity allows these tiny galaxies to produce more massive stars, and, probably because massive stars have stronger magnetic fields, their explosive deaths can leave behind highly magnetized neutron stars, or magnetars.

The universe is a wild and weird place, and two recent findings from orbiting space telescopes illustrate just how bewildering it can be: a monster - sized black hole in one of the tiniest galaxies known and a huge -LSB-...]
