Barred spiral galaxy

A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in approximately two-thirds of all spiral galaxies. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well. Our own galaxy, the Milky Way, is classified as a barred spiral galaxy.

Edwin Hubble classified spiral galaxies of this type as "SB" (spiral, barred) in his Hubble sequence, and arranged them into sub-categories based on how open the arms of the spiral are. SBa types feature tightly bound arms, while SBc types are at the other extreme and have loosely bound arms. SBb-type galaxies lie in between. SB0 is a barred lenticular galaxy. A new type, SBm, was subsequently created to describe somewhat irregular barred spirals, such as the Magellanic Cloud galaxies, which were once classified as irregular galaxies, but have since been found to contain barred spiral structures. Among other types in Hubble's classifications for the galaxies are: spiral galaxy, elliptical galaxy and irregular galaxy.

SBB (band)

SBB (first known as Silesian Blues Band, later as Szukaj, Burz, Buduj – Polish for "Search, Break up, Build") is a Polish progressive rock band formed in 1971 in Siemianowice, Upper Silesia by multi-instrumentalist and vocalist Józef Skrzek. It was one of the most popular super-groups in Poland in the 1970s; they also toured Czechoslovakia, East and West Germany, Finland, Sweden, Denmark, Hungary, Austria, Switzerland, the Netherlands, Belgium and the United States. The band split up in 1980 but was briefly re-activated in 1991, 1993, 1998 and finally in 2000. In the years 1971-1973 SBB performed as Niemen supporting Czesław Wydrzycki, opening the Olympic Games in Munich and recording for the CBS label.
