Ursa Major is a large sprawling constellation, the third largest in fact. It's mainly known as the home of the Big Dipper (UK: the Plough), certainly the best known asterism in all the heavens.
Ursa Major, the Big Bear, is one of the most familiar constellations. For those of us at northern latitudes, it can be seen all year as the constellation is circumpolar.
Ursa Major as depicted on the Uranographia of Johann Bode (1801). The familiar shape popularly known as the Plough or Big Dipper is made up of seven stars in the rump and tail of the bear.

Ursa Major represents the Great Bear as well as the Wagon. That later connection dates bact to Mesopotamia, where Enlil, god of weather, was depicted riding it as chariot pulled by a winged dragon (Draco).

According to Burnham, Alcor is part of a star cluster including at least 16 other stars from the Ursa Major area of the sky, as well as Alioth, Merak, Mizar, Phecda, and Megrez in the Big Dipper.

SU Ursa Majoris stars -- the secondary (normal) star is massive enough that its gravitational field makes the accretion disk around the white dwarf precess, which triggers a "superoutburst" -- an extended period of high brightness.

The Ursa Major Moving Group is one prominent naked-eye visible moving group in the night sky. (Except for α Ursae Majoris and Î- Ursae Majoris, all the stars in the Plough/Big Dipper are part of this group).

Part of URSA MAJOR forms the easily spotted Big Dipper.
By the way, the Big Dipper isn't a true constellation. It's a "pseudo-constellation" (and that is why I only capitalize the first letters).
The stars of the Big Dipper are very bright.

Definition: constellation: One of the stellar patterns identified by name, usually of mythological gods, people, animals and objects. Also the region of the sky containing that star pattern.
Constellation Ursa Major is only visible from the northern hemisphere. The seven stars of the Big Dipper in this constellation are famous as the traveller's guide to Polaris, the North Star.

A classification of stellar spectra according to luminosity, devised by Morgan, Keenan and Kellman (see Luminosity Class).
The constellation Ursa Major is the site of a spiral galaxy called M109. It is classified as a barred spiral. The elongated shape of its central core can be seen even in small instruments.

Some common constellations are the Big Dipper which is actually part of a larger constellation called Ursa Major (the Great Bear) and the Little Dipper, part of Ursa Minor. Ursa Major is among the largest of the constellations.
Mythology: Camelopardalis is a modern constellation created to fill a vast region of faint stars surrounded by the brighter and more famous constellations of Ursa Major, Auriga, Perseus, Cassiopeia, and others.
The second-last star in the handle of the Big Dipper and the 4th brightest star in Ursa Major. With good eyesight one can make out a faint companion just to the east of Mizar, called Alcor or 80 Ursae Majoris.
In 1996 the Hubble Space Telescope team released an image of a part of the sky in the constellation of Ursa Major. This deep (long) exposure revealed galaxies at immense distances from our own Milky Way.
Arcturus takes its name from its nearness to the sky Bears, Big and Little Bears, Ursa Major, and Ursa Minor. From Arktouros or Arctophilax, "the Bear Guard" and also called "the Bear Watcher". The "Herdsman", or "driver of oxen" are other titles.
The Chandra observation traced a patch of sky known as the Lockman Hole in the constellation Ursa Major (containing the Big Dipper).
Lying in Ursa Major just over five degrees north-west of Alkaid (eta UMa), the end star of the Plough, M101 is circumpolar from the UK. In late August, M101 is about 50 degrees up around 9.
Alkaid, the end star of the Big Dipper handle is also the tail star of Ursa Major, the Big Bear. By drawing a line from the tail star of the Big Bear to the tail star of Leo, the Lion, you can find Canes Venatici's place in the sky everytime.
12 million light-years from us, the galaxy lies in the constellation Ursa Major; this image covers approximately 7.9 arcminutes across (28,000 light-years). The image is combined from data taken March 27-29, 2006, for a total of 13.7 hours.

The stars most often used on these instruments are either the 'guards' of the Little Bear (Ursa Minor) or the 'pointers' of the Great Bear or Plough (Ursa Major). These are known as the Little Dipper and Big Dipper, respectively, in the USA.

New works were also written, and even the name of algebra tells us about its origin. In astronomy, Arab scholars also left a legacy, that is easily seen in the names still used for most of the brilliant stars in the sky (see, e.g. Ursa Major) ...
