The results presented by Lockman suggest that, as some astronomers have predicted, the hot gas in the halo slowly cools and condenses into hydrogen clouds along with wispy filaments that connect them.

Together with star - formation histories and halo gas, these observations will dissect the past evolution and current activity of nearby galaxies.

The Milky Way (like other spiral galaxies) is surrounded by a large halo region which contains globular clusters, large clouds of hydrogen gas, and a huge mass of the mysterious dark matter.

Beyond the star - filled disk of the Milky Way, there exists an extensive yet diffuse halo of hydrogen gas.

Evidence for a halo of the Milky Way was originally provided by data collected by the Chandra X-ray Observatory and it is estimated that the halo of gas, which is several times larger than the galaxy itself, has a mass comparable to the mass of all the stars in the galaxy.

«To reach the Milky Way, it must survive its journey through the Galactic halo, which is a low - density environment of million - degree gas that surrounds our galaxy, Antwi - Danso said.

On September 24, 2012, astronomers using NASA's Chandra X-Ray Observatory announced that our Milky Way Galaxy and some of its satellite galaxies are surrounded by an enormous halo of extremely hot gas at a temperature of one to 2.5 million kelvins.

«The latest data confirm these results and show that instead of trailing away smoothly from the Galactic plane, a significant fraction of the hydrogen gas in the halo is concentrated in discrete clouds.

They are now moving through an extended halo of hot, diffuse gas that envelops the Milky Way.

According to the researcher, the ubiquitous nature and dynamics of these newly discovered clouds support the theory that they are condensing out of the hot gas that is lifted into the halo through supernova explosions.

Using the exquisite sensitivity of the National Science Foundation's Green Bank Telescope, astronomer Jay Lockman of the National Radio Astronomy Observatory in Green Bank, West Virginia, has produced the best cross-section ever of the Milky Way Galaxy's diffuse halo of hydrogen gas.

That shouldn't be too surprising: Much of a halo's gas has a scorching temperature of a million degrees Celsius (1.8 million degrees Fahrenheit) or more.

But haloes also contain much cooler gas that's only about 10,000 ºC (or about 18,000 ºF).
