WebOne of the most interesting observation areas in this context is the center of the Milky Way, where the black hole with the largest angular diameter as seen from Earth is located. The compact radio source Sagittarius A* (SgrA*) at the very center of the Milky Way has been observed over more than five decades (see Genzel et al. [ 1 ] and ...
WebThe center panel shows the measured positions and the right panel has the proper motion removed to better show the parallax effect. This data gives a distance to the Galactic Center of 7.9 +/- 0.8 kpc. Hopefully in few years the distance to the center of the Milky Way can be measured to very high accuracy with this simple and elegant technique. WebMilky Way is a flattened disk ~15 kpc across & ~3 kpc thick The Sun is located slightly off-center. Sketch based on Kapteyn's paper. Harlow Shapley (1915 thru 1921) ... Shapley & Kapteyn thought it was smaller than it actually is, and so overestimated the size of the Milky Way. Robert Trumpler (1930) showed that interstellar dust absorption was ...
WebThe centre of the Milky Way is more than 8 kiloparsecs (26,000 ly) from the Earth, and the Milky Way is roughly 34 kiloparsecs (110,000 ly) across. The Andromeda Galaxy is about 780 kpc (2.5 million ly) away from the Earth. Megaparsecs and gigaparsecs WebBased on the D 25 isophote at the B-band (445 nm wavelength of light), the Large Magellanic Cloud is about 9.86 kpc (32.2 kly) across. It is roughly one-hundredth the mass of the Milky Way and is the fourth-largest galaxy in the Local Group, after the Andromeda Galaxy (M31), the Milky Way, and the Triangulum Galaxy (M33).
WebThe center of our disk galaxy, the Milky Way, is dominated by a boxy/peanut-shaped bulge. Numerous studies of the bulge based on stellar photometry have concluded that the bulge stars are exclusively old. The perceived lack of young stars in the bulge strongly constrains its likely formation scenarios, providing evidence that the bulge is a ...
