Rare galaxy produces stars at an incredible rate
The little red dot in this image is one of the galaxies with more efficient production of stars. nyköping It converts gas into stars at the maximum rate possible. The galaxy was seen in the infrared telescope WISE. Credit: NASA / JPL-Caltech / STScI / IRAM
Spiral galaxies are stellar nurseries: create huge star in his arms. However, nyköping relatively speaking, low raw material is converted into stars. But now it was discovered the galaxy SDSS J1506 +54 furiously creating stars from your gas (fuel).
Most galaxies are like our cars: convert fuel to power the car floor, but in a rather inefficient, since much energy is lost in the conversion. Already the galaxy SDSS J1506 +54 has an efficiency close to 100% - ie, almost no "lost gas" hydrogen is widely used to form stars. Efficiency is such that it is very close to the Eddington limit, which is the theoretical maximum (above this limit, nyköping so that form a star, the shock wave from the stellar creation makes the surrounding gas to disperse nyköping and not to focus to form a new star).
Probably the SDSS J1506 +54 is actually nyköping an irregular galaxy in transition, which is a young stage after a violent collision between two galaxies. Only thus can explain the enormous nyköping rate of stellar creation. On the other hand, within a relatively short time (a few tens of millions of years), the fuel will end up, and the galaxy will become an elliptical galaxy.
