The Milky Way bar is made of nougat, topped with caramel and covered with milk chocolate. It was created in 1923 by Frank C. Mars and originally manufactured in Minneapolis, Minnesota. The name and taste derived from a then-popular malted milk drink ( milkshake) of the day, not after the astronomical galaxy.
To compare the relative physical scale of the Milky Way, if the Solar System out to Neptune were the size of a US quarter (24.3 mm (0.955 in)), the Milky Way would be approximately at least the greatest north–south line of the contiguous United States.
The Sculptor Galaxy (NGC 253) is an example of a disc galaxy. A galactic disc (or galactic disk) is a component of disc galaxies, such as spiral galaxies, lenticular galaxies, and the Milky Way. Galactic discs consist of a stellar component (composed of most of the galaxy's stars) and a gaseous component (mostly composed of cool gas and dust).
Galactic Center. 17 45 40.04, −29° 00′ 28.1″. The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center. The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy.
The X-shape makes up 45% of the mass of the bulge in the Milky Way. The boxy/peanut bulges are in fact the bar of a galaxy seen edge-on. Other edge-on galaxies can also show a boxy/peanut bar sometimes with an X-shape. Central compact mass ESO 495-21 may host a supermassive black hole, an unusual feature for a galaxy of its size.
Galactic bulge. Rich pioneered the modern study of the central bulge/bar stellar population of the Milky Way galaxy, obtaining the first spectroscopy and metal abundances for stars in the Galactic bulge, showing an average metal content similar to that of the Sun and an abundance distribution following the "simple" closed box model of chemical evolution; this required the central bulge of the ...
The rotation curve of a disc galaxy (also called a velocity curve) is a plot of the orbital speeds of visible stars or gas in that galaxy versus their radial distance from that galaxy's centre. It is typically rendered graphically as a plot, and the data observed from each side of a spiral galaxy are generally asymmetric, so that data from each ...
According to research published in August 2015, very large galaxies may favor the birth and development of habitable planets more than smaller galaxies such as the Milky Way. In the case of the Milky Way, its galactic habitable zone is commonly believed to be an annulus with an outer radius of about 10 kiloparsecs (33,000 ly) and an inner ...
8.5 g. Carbohydrate. 35.3 g. Mars, commonly known as Mars bar, is the name of two varieties of chocolate bar produced by Mars, Incorporated. It was first manufactured in 1932 in Slough, England by Forrest Mars, Sr. [2] The bar consists of caramel and nougat coated with milk chocolate . An American version of the Mars bar was produced which had ...
The thin disk is a structural component of spiral and S0-type galaxies, composed of stars, gas and dust. It is the main non-centre (e.g. galactic bulge) density, of such matter. That of the Milky Way is thought to have a scale height of around 300–400 parsecs (980–1,300 ly) in the vertical axis perpendicular to the disk, [1] and a scale ...
