Will the Milky Way become gaseous? A new study says yes



An excessive amount of gas flowing into the Milky Way has been discovered by astronomers – though the reason for the phenomenon remains a mystery.

According to NASA's Hubblesite, data comes from about 10 years ago The Hubble Space Telescope shows more gas coming in than came out, said Andrew Fox, astronomer and lead author of an upcoming study for The Astrophysical Journal.

Using the Cosmic Origins Spectrograph (COS) technology through the telescope, gas away from the galaxy appears redder as gas approaches, blue appears. This led to the unexpected finding that the amount of gas entering the Milky Way is far greater than the amount that escapes.

"Our Milky Way is a thrifty galaxy," said Hubblesite. "Supernovae and fierce stellar winds blow gas from the galactic disk, but this gas falls back onto the galaxy to form new generations of stars."

The process itself ̵

Hubblesite said the study suggests that a theoretical source behind the "unbalanced books" of the Milky Way is the intergalactic medium – a mass of hydrogen gas that is believed to be it exists between different galaxies.

Fox, an astronomer at the Space Telescope Science Institute (which carries out scientific operations for Hubble), believes, however, that the Milky Way is able to use its magnetism to steal gas reserves from smaller, nearby galaxies.

Co-author of the study, Rongmon Bordoloi of North Carolina State University, added, "Hubble COS's original observations served to probe the universe far beyond our galaxy, but we went back to them. It's a merit of the Hubble Archive, that we can use the same observations to study both the near and the distant Universe Examine both local and remote celestial objects. "

The Hubble Space Telescope launched on April 24, 1990, and has had more since then made as a million observations. With two 25-foot solar panels, it draws its energy from the sun and sends about 120 gigabytes of data once a week.

Experts say the Milky Way is currently the only galaxy we can closely monitor with the telescope.
