Galaxies come in three main types: ellipticals, spirals, and irregulars. A slightly more extensive description of galaxy types based on their appearance is given by the Hubble sequence. While the Hubble sequence does encompass all galaxies, it is entirely based upon visual morphological type. Hence, it may miss certain important characteristics of galaxies such as star formation rate. Our own galaxy, the Milky Way, sometimes simply called the Galaxy (with uppercase), is a large disk-shaped barred spiral galaxy about 30 kilopars ...

This account of the history of the investigation of our own and other galaxies is largely taken from [1]. In 1610, Galileo Galilei used a telescope to study the bright band on the night sky known as the Milky Way and discovered that it was composed of a huge number of faint stars. In a treatise in 1755, Immanuel Kant, drawing on earlier work by Thomas Wright, speculated (correctly) that the galaxy might be a rotating body of a huge number of stars, held together by gravitational forces akin to the solar system but on much larger scale ...

A barred spiral galaxy is a spiral galaxy with a band of bright stars emerging from the center and running across the middle of the galaxy. Spiral arms appear to emerge from the ends of the "bar" in these galaxies, whereas they appear to emerge directly from the core in ordinary spiral galaxies. Edwin Hubble classified these types of spiral galaxies as "SB" ("Spiral", "Barred"), and arranged them into three sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at ...

Andromeda Galaxy photographed in 1899 The Andromeda Galaxy (also known as Messier 31, M31, or NGC 224; older texts often call it the Andromeda Nebula) is a giant spiral galaxy in the Local Group, together with the Milky Way galaxy. It is at a distance of approximately 2.5 million light years or 770 kpc, in the direction of the constellation Andromeda. With a mass of about 1.5 times that of the Milky Way, it is the dominant galaxy of the Local Group, which consists of about 30 sma ...

An active galaxy is a galaxy where a significant fraction of the energy output is not emitted by the normal components of a galaxy: stars, dust and interstellar gas. This energy, depending on the active galaxy type, can be emitted across most of the electromagnetic spectrum, as infrared, radio waves, UV, X-ray and gamma rays Frequently, the abbreviation AGN (Active Galactic Nuclei) is used, since most active galaxies appear to be powered by a compact region in the galactic centre. Some of these compact regions emi ...

The Andromeda Galaxy was observed in 964 by the Persian astronomer 'Abd Al-Rahman Al Sufi, who described it as a "small cloud". The first description of the object based on telescopic observation was given by Simon Marius (1612), who is often wrongly credited as the discoverer of the Andromeda Galaxy. In 1885, a supernova (known as "S Andromedae") was seen in the Andromeda Galaxy, the first and so far only one observed in that galaxy. At the time, it was thought to be much less luminous and unrelated event calle ...

Abell 1835 IR1916 (also known as Abell 1835, Galaxy Abell 1835, or Galaxy Abell 1835 IR1916) is a candidate for being the most distant galaxy ever observed. It was discovered by French and Swiss astronomers of the European Southern Observatory, namely Roser Pelló, Johan Richard, Jean-François Le Borgne, Daniel Schaerer, and Jean-Paul Kneib. The astronomers used a near-infrared instrument on the Very Large Telescope to detect the galaxy; other observatories were then used to make an image of it possible. The Obse ...

The Canis Major Dwarf Galaxy is located in the same part of the sky as the constellation of Canis Major. The galaxy contains a relatively high percentage of red giant stars, and is thought to contain an estimated one billion stars in all. The Canis Major dwarf galaxy is classified as an irregular galaxy and is now thought to be the closest neighbouring galaxy to the Milky Way, being located only 42,000 light-years from the Galactic Center and approximately 25,000 light-years away from our Solar System. It has a roughly elliptic ...

Seyferts, quasars and blazars are the main types of AGNs that emit high-energy radiation (X-rays). Quasars, in particular, are thought to be the most consistently luminous objects in the known universe. Radio galaxies are a heterogeneous group of radio-emitting objects. Most of them have huge symmetrical lobes from which the greater part of the radio emission comes. Some of them show a jet or jets (the most famous example being the giant galaxy M87 in the Virgo cluster) coming directly from the nucleus and going to the lobes. T ...

The Andromeda Galaxy is approaching us at about 300 kilometres per second, so it is one of the few blue shifted galaxies. Given our motion inside the Milky Way, one finds that the Andromeda Galaxy and the Milky Way are approaching one another at a speed of 100 to 140 kilometres per second. However, this doesn't mean it will collide with the Milky Way, since the galaxy's tangential velocity is unknown. If it is on a collision course, the impact is predicted to occur in about 3 billion years. In that case the two galaxies will merge to form a giant elliptical galaxy. Such ...

The early pioneer of studies on the formation of the spiral arms was Bertil Lindblad. He realised that the idea of stars arranged permanently in a spiral shape was untenable due to the "winding dilemma". Since the speed of rotation of the galactic disk varies with distance from the centre of the galaxy, a radial arm (like a spoke) would quickly become curved as the galaxy rotates. The arm would, after a few galactic rotations, become increasingly curved and wi ...

Groups of galaxies are the smallest aggregates of galaxies. They typically contain fewer than 50 galaxies in a diameter of 1 to 2 Megaparsecs (Mpc) (see 1 E22 m for distance comparisons). Their mass are approximately 1013 solar masses. The spread of velocities for the individual galaxies is about 150 km/s. The group which contains our own galaxy, the Milky Way, is called the Local Group, and contains more than 40 galaxies. ...
