Usually, like our not-so-environmentally conscious galaxy, star formation occurs in clumps, where large clouds of gas collect along spiral galaxies' elegant spiral arms. This leaves a lot of gaseous leftovers that are strewn throughout interstellar space that may never be used to birth stars.
It appears SDSSJ1506+54 is different; it has a mechanism that funnels all the available gas throughout the galactic structure into the galactic core, where a maelstrom of star formation is constantly being fed. In effect, it has optimized its production line, using all available gas for the construction of stars. There appears to be little wasted in this supercharged galaxy.
"We are seeing a rare phase of evolution that is the most extreme - and most efficient - yet observed," said Geach.
"While this galaxy is forming stars at a rate hundreds of times faster than our Milky Way galaxy, the sharp vision of Hubble revealed that the majority of the galaxy's starlight is being emitted by a region with a diameter just a few percent that of the Milky Way," he added.
