A collection of many galaxies, each consisting of hundreds of billions of stars. What is a spiral galaxy? Galaxy composed of a flattened, star-forming disk component which may have spiral arms and a large central bulge

WebThe value of D roughly ranges from 0.035 dex for O4-5 type stars to nearly 0.500 dex for A2-type stars, and then back for cooler spectral types to 0.035 dex in F9-type stars. The λ 1 − 3700 goes roughly from 70 Å for dwarfs to λ 1 − 3700 ≃ − 5 Å for supergiants, which indicates that λ 1 is a well-resolved quantity useful for the ...

WebExamples of regular spiral galaxies: ( visually) M31 (Andromeda Galaxy), M74, M81, M104 (Sombrero Galaxy), M51a (Whirlpool Galaxy), NGC 300, NGC 772 . Examples of barred spiral galaxies: M91, M95, NGC 1097, … WebAstronomers classify galaxies into three major categories: Spiral Galaxies, Elliptical Galaxies, Irregular galaxies. Galaxies come in three major types: spiral, elliptical, and irregular. Spiral Galaxies * such as our Milky Way, look like flat white disks with yellowish bulges at their centers. Scientists sometimes categorize galaxies based on their shapes and physical features. Other classifications organize galaxies by the activity in their central regions – powered by a supersized black hole – and the angle at which we view them. See more Our Milky Way is one example of a broad class of galaxies defined by the presence of spiral arms. These galaxies resemble giant rotating … See more Elliptical galaxies have shapes that range from completely round to oval. They are less common than spiral galaxies. Unlike spirals, elliptical galaxies usually contain little gas and dust and show very little organization or … See more Irregular galaxies have unusual shapes, like toothpicks, rings, or even little groupings of stars. They range from dwarf irregular galaxies with 100 million times the Sun’s mass to … See more Lenticular galaxies are a kind of cross between spirals and ellipticals. They have the central bulge and disk common to spiral galaxies but no arms. But like ellipticals, lenticular … See more ghostbusters fall out boy lyrics
