The data gathered from Hubble Telescope revealed secret of massive halo of Andromeda galaxy. Researchers found that the halo is nearly 100 times heavier than the moon.
Andromeda is the nearest largest galaxy present in the Milky Way. It is commonly known as Messier 31 or M31. It is around 2.5 million light years away from the galaxy. Hence, it can be easily observed on the night sky with naked eyes. It emits 25 percent more bright as compared to the Milky Way
With the help of data, scientists estimate that Andromeda’s halo is about to meet the halo of Milky Way. As per the predictions, the merger will give birth to an enormous elliptical. However, it will take more than four billion years for the completion of the process.
Nicholas Lehner, the main author of the study, explains Halos in detail. He informs that halos are the gaseous atmosphere of galaxies. The features of gaseous halos control the speed of formation of stars. Currently, scientists are unable to figure out whether any kind of halo is present around Earth or not.
Researchers are pretty optimistic that the new findings can provide significant details regarding Milky Way. It can inform about the structure and development of spiral galaxies like Andromeda.
