Milky Way Sucks Out all Star Forming Hydrogen from Nearby Dwarf Galaxies

Astronomers discovered that dwarf galaxies surrounding the Milky Way Galaxy apparently don't have the appropriate and sufficient quantity of gases needed to form stars.

Scientists believe the Milky Way has been sucking out the gases from these dwarf galaxies.

Data from the Green Bank Telescope of the National Science Foundation in West Virginia shows new radio observations as proof specific boundary galaxies near the Milky Way classified as dwarf spheroidal galaxies don't have hydrogen. Across the boundary, however, other galaxies are awash in hydrogen.

The Milky Way Galaxy is considered the largest in a compact group of galaxies. Several dwarf galaxies surround the Milky Way.

The smallest ones are described as spheroidal galaxies believed to be remnants left over from the early stages of the formation of galaxies.

There are other smaller and irregularly shaped galaxies, as well, but they aren't within the reach of the gravitational pull of the Milky Way. These irregular shaped galaxies are located on the outskirts of the Milky Way and contain massive amounts of neutral hydrogen gas pivotal to the formation of stars and galaxies.

The Green Banks Telescope is the largest fully steerable radio telescope in the world., This new data confirms those nearby dwarf galaxies don't contain hydrogen needed for the birth of stars.

According to Kristine Spekkens, lead author of the study from the Royal Military College of Canada, scientists have found solid evidence the Milky Way is surrounded by dwarf galaxies absolutely devoid of any neutral atomic hydrogen.

This hydrogen lacking galaxy boundary is estimated to be 1,000 light years away. All the dwarf galaxies are gravitating towards the Milky Way and its halo of hydrogen plasma.

Scientists believe the dense plasma halo of the Milky Way is affecting the composition of surrounding dwarf galaxies.

This study was published in the journal, Astrophysical Journal Letters.
