The scientists have discovered 11 different runaway galaxies that had been flung far away from their original homes, allowing to wander into deep space.
The latest discovery has thrown light on a substantial amount of knowledge about such strange features.
The astronomers explain an object is known as a “runaway” when it is able to travel faster than escape velocity. This makes it leave the home and never return back. According to the scientists, runaway stars perfectly fit to this description when they speed more than one million miles per hour. A runaway galaxy should move even faster, i.e. at approximately six million miles per hour.
When the researchers began their exploration, they initially sought to discover new members that belong to a class of galaxies called the compact ellipticals. According to the researchers, these tiny star blobs are larger than the clusters of star. However, they are smaller than typical galaxies. If compared, our Milky Way galaxy is 100,000 light-years across.
Totally, the astronomers have spotted nearly 200 new compact galaxies. Approximately 11 of these galaxies had been completely isolated did not seem to be lying near any large galaxy or any particular cluster of galaxy. The million dollar question here arises is what force led to the creation of these galaxies.
According to the scientists, they have likely developed from a classic three-body interaction. A compact elliptical is expected to have been paired along with a large galaxy which has likely robbed it of all its stars. Then the impact of a third galaxy could interrupt this pair, causing it to fling in a compact elliptical direction. The larger galaxy could then absorb the complete third galaxy.
The findings of the study were published in the journal Science.
