MCG +07-33-027 is an isolated spiral galaxy[2] located about 330 million light-years away[3] in the constellation Hercules.[4] It has a very high rate of star formation which would make it a starburst galaxy. Normally, starburst galaxies are triggered by the collision of another galaxy. However most galaxies are in groups or clusters, while MCG +07-33-027 is solitary. Therefore, the cause of the starburst was not due to a collision or by the passing of a nearby galaxy and so the cause of the activity remains unknown.[2]
