Spiral Galaxy NGC 772 and Elliptical Galaxy NGC 770, aka Arp 78, are a physically close pair of galaxies in the Constellation of Aries NGC 772, the host of Supernovae 03 hl and 03 iq, is a Spiral Galaxy with a small, very bright, diffuse nucleus It has many weak, tightly coiled arms, one abnormally strongWithout a defined structure, elliptical galaxies can be oval shaped, and tend to consist of stars that orbit around a loosely formed center of gravity These elliptical star clusters can also be formed by the collision between two galaxies, which disrupts the regular spiral form into an elliptical mass of starsMessier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy with several trillion stars in the constellation VirgoOne of the most massive galaxies in the local universe, it has a large population of globular clusters—about 15,000 compared with the 150–0 orbiting the Milky Way—and a jet of energetic plasma that originates at the core
Elliptical galaxies and Spiral Galaxy have one thing in common apart from stars is that they both have a Supermassive black hole at the centre of the galaxy Stars in a spiral galaxy orbit round the central point, the Supermassive Black Hole but with elliptical galaxies, there is no order, stars orbits can be randomElliptical galaxies also constitute some of the smallest galaxies in the universe These galaxies are called dwarf elliptical galaxies and dwarf spheroids Relative to normal ellipticals they are very faint, and are often found in galaxy clusters or near large spiral galaxiesTo make your task easier, you will be presented with four buttons Spiral Galaxy, Elliptical Galaxy, Star/Don't Know, and Mergers The spiral galaxy button will be subdivided into Clock (for clockwise spirals), Anti (for anticlockwise spirals), and Edge On (for edgeon spirals) You will need to click on the most appropriate button
The notation for elliptical galaxies is E Unlike the additional spiral tightness classification of barred and typical spiral galaxies, elliptical galaxies have a more specific classification of the numbers 0 through 7 The 0 represents the most round elliptical galaxy and 7 means that the galaxy is very ovular Irregular GalaxiesElliptical galaxies appear typically yellowred, as opposed to spirals which have spiral arms that appear quite blue Much speculation continues on how each type of galaxy can form, on whether ellipticals can evolve from colliding spirals, or spirals can be created from colliding ellipticals, or both Besides the spiral galaxy on the right, all other images in this picture are of galaxies that lie well behind the Coma Cluster APOD 04 June 16 Elliptical Galaxy M87 ExplanationSpiral galaxies are twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars Most of the galaxies that scientists have discovered so far are spiral

How Are Elliptical Galaxies Different From Spiral Galaxies Quora
The Milky Way is thought to be a barred spiral galaxy, as are about 2/3 of all observed spiral galaxies Spiral and barred spiral galaxies are subclassified by how tightly wound the spiral arms appear Elliptical galaxies don't show any structure, but have a smooth ellipsoidal shape, appearing as a large spherical or elliptical ball of stars Elliptical galaxies can be classified in terms of how long and thin they appear Elliptical galaxies don't actively create new stars, but usuallyA spiral galaxy consists of a spinning, flattened disk with arms that rotates very fast An elliptical galaxy is the most common type of galaxy, has a roundish shape, and demonstrates little or no star formation An irregular galaxy is a galaxy with no defined shape that has very young stars Learning OutcomesThe result of the survey showed that the galaxies observed by Hubble, the spiral and the elliptical galaxies are linked together evolutionarily

Elliptical Galaxies Elliptical galaxies consist almost entirely of old stars and have shapes that are spheres or ellipsoids (somewhat squashed spheres) (Figure 4) They contain no trace of spiral arms Their light is dominated by older reddish stars (the population II stars discussed in The Milky Way Galaxy )The nucleus of a spiral galaxy is a sharppeaked area of smooth texture, which can be quite small or, in some cases, can make up the bulk of the galaxy Both the arms and the disk of a spiral system are blue in colour, whereas its central areas are red like an elliptical galaxy The normal spirals are designated S and the barred varieties SBA spiral galaxy is a galaxy that has a spiral shape Most of the galaxies in the universe observed by astronomers are spiral galaxies (about 77%) They are divided into two Barred spiral galaxy (classified as "SB") Unbarred spiral galaxy (classified as "SA") NGC 1300 and NGC 1672 are examples of barred spiral
