Hubble Sees Our Galaxy Sucking Up a Mysterious Amount of Gas

It seems that our galaxy may be absorbing an unidentified gas. The galaxy functions as to test the gases out. It first absorbs them and then releases them through supernovas and stellar winds. With good use of the data collected from the Hubble telescope, a team of astronomers have said that the galaxy may be taking more mass in than it is releasing.

Researchers have collected data from 270 different views which have been taken by the Cosmic Origins Spectrograph, a part of the Hubble. They found clouds that moved fast and orbit the Milky Way. These appear to absorb UV rays from around them. Doppler shifts permit the researchers to determine whether the gas is flowing into the galaxy or out of it.

187 such clouds have been found to be absorbing wavelengths which are shorter or longer than expected.

When calculating, these researchers found that gas was pouring into the galaxy more than it was going out. The Milky Way could possibly be in an inflow age of its life, but the idea that our galaxy uses gases to make stars and then recycles the materials, when the star dies, is quite probable.

The extra mass may be coming from an intergalactic medium and smaller satellite galaxies according to the Space Telescope Science Institute.

The calculations are made on the basis of calculations which are made at the sight of photos of the Milky Way. The rate of flow of the mass cannot be calculated, as is the case of the UV absorption. These measurements have shown that the higher rate of inflow of gas is happening in the galaxy. However, these calculations are dependant on the day’s photo and nothing more. There is no way to tell when this may accelerate or slow down.

Though the galaxy is a mystery, these studies help us to understand exactly why we have been put on this universe and how the galaxy makes stars.
