Using 10 years of data from NASA's Hubble Space Telescope, the team of astronomers concluded that there is more gas coming into our galaxy than leaving it. Rather than an equilibrium of gas entering and escaping, there is a significant imbalance, though the team behind this finding has not yet found the source for this gaseous disparity.

The researchers used data from Hubble's Cosmic Origins Spectrograph (COS), which allows the space telescope to study objects that absorb or emit light and determine aspects such as their temperature, chemical makeup, velocity and density. With COS, the team could observe and track the movement of gases in the galaxy: the gases appear redder as they move away from our galaxy, and bluer as they get closer through the phenomena known as redshift and blueshift.
