 Hubble assist  Scientists  to Investigate Andromeda Galaxy Halo

Andromeda Galaxy has recently been examined by a team lead by University of
Notre Dame astrophysicist Nicolas Lehner. It was gathered that descriptions and
images from NASA’s Hubble Space Telescope improve yet more new data to aid
modern astronomers get an improved understanding of the origins of our

Based on the newfangled research indicates the galaxy has a massive halo
surrounding it and the team approximations  covers that the mass of this halo is undoubtedly
equal to the mass of half of the stars in the whole of the Andromeda galaxy.

“Halos are the gaseous atmospheres made up of galaxies,” University of Notre
Dame astrophysicist Nicolas Lehner elucidates. “The chattels and features of these
gaseous halos rheostat and regulate the rate at which stars form in galaxies.”And learning this one is significant because researchers now guesstimate it
is six times larger than they originally believed.

In addition, co-investigator J. Christopher Howk—who is also from the
University of Notre Dame—shares “As the light from the quasars travels toward
Hubble, the halo’s gas will absorb some of that light and make the quasar
appear a little darker in just a very small wavelength range.”  Howk, adds that “This is a new milestone since
typically only one quasar is used to probe the halos of galaxies beyond the
Local Group.  Here we have accumulated
and assembled a large sample of quasars that unswervingly validate the true
extent of the halo of a single massive galaxy.”

He continues, “By measuring the dip in illumination in that range, we can
tell how much halo gas from M31 there is, flanked by us and that quasar.”

In conclusion, Lehner says, “When we perceive and detect huge egg-shaped  assemblies and galaxies, we discover a lot of
cold gas around these galaxies that should fall onto the galaxy, but doesn’t.”
