The Milky Way galaxy has several components, such as the bulge, disk and halo. Unravelling the assembly history of these stellar populations is often restricted because of difficulties in measuring accurate ages for low-mass, hydrogen-burning stars. Unlike these progenitors, white dwarf stars, the...

Earth 16,000 MPH Faster, 2000 Light-Years Closer to Supermassive Black Hole in the Center of the Milky Way Milky Way Is Being Twisted and Deformed With Extreme Violence by the Gravitational Force of the LMC’s Dark Matter Halo Astronomers Discover New “Fossil Galaxy” Buried Deep Within the...
s Chandra X-ray Observatory was used to estimate that the mass of the halo is comparable to the mass of all the stars in the Milky Way galaxy. If the size and mass of this gas halo is confirmed, it could be the solution to the “missing-baryon” problem for the Galaxy. Credit: ...
In addition, we recover the Sagittarius dwarf galaxy (Sgr) leading-arm material and the Virgo Over-Density. The derived distances, together with the number of sub-giant stars associated with each substructure, enables us to derive the integrated luminosity for the features. The tenuous, low ...
Forerunner name for the Milky Way galaxy. PINCH FUSION Covenant shipboard and station fusion reactors that use focused gravity generators to replicate conditions inside the core of stars. PLASMA TORPEDO Command link-guided projectile surrounded by a superheated plasma sheath. ...
We present the first measurements of the outermost edges of the Milky Way (MW) halo in terms of the depletion and turnaround radii. The inner depletion radius, $r_\mathrm{id}$, identified at the maximum infall location, separates a growing halo from the draining environment, while the turn...
A galactic disk in a spiral galaxy is generally believed to be embedded in an extended dark matter halo, which dominates its dynamics in the outer parts. However, the shape of the halo is not clearly understood. Here we show that the dark matter halo in the Milky Way Galaxy is prolate ...
