Observations show that when they were bursting into life, the majority of these galaxies were small, just a few hundred light-years across--comparable to the size of individual star-forming regions in the Milky Way and its companions, such as 30 Doradus
(Tarantula Nebula; S&T: Nov.

Nebula, a vast, sculpted landscape of gas and dust where thousands of stars are being born.
The researchers who published the report examined observations made in the star-forming region 30 Doradus
The discovery, made in the gigantic star-forming region 30 Doradus
in the Large Magellanic Cloud galaxy, has 'far-reaching' consequences for our understanding of how stars transformed the pristine Universe into the one we live in today.
Also known as 30 Doradus
, the Tarantula Nebula is a raucous region of star birth that resides 170,000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way.
Some astronomers believe that 30 Doradus
is the nucleus of this neighbourhood galaxy, but on the other hand it is not very centrally placed.
But the star 30 Doradus
016 was born in a rough neighborhood.
Some of the New Zealand observations include mapping 30 Doradus
, or the Tarantula Nebula, in the nearby Large Magellanic Cloud.
Within it is the extraordinary H II region 30 Doradus
, better known as the Tarantula Nebula.
The massive binary star R144 can be found in an outer area of the star-forming region 30 Doradus
in the Large Magellanic Cloud.
What at first was thought to be only one cluster in the core of the massive star-forming region 30 Doradus
(also known as the Tarantula Nebula) has been found to be a composite of two clusters that differ in age by about one million years.
We now know that in many star-forming regions, such as 30 Doradus
, you find such pillars," Livio adds.
