In its early stages of development, LIVESTREAM television employed a combination of optical, mechanical and electronic technologies to capture, transmit and display a visual image. By the late 1920s, however, those employing only optical and electronic technologies were being explored. All modern television systems relied on the latter, although the knowledge gained from the work on electromechanical systems was crucial in the development of fully electronic television.

According to a report from the International Centre for Radio Astronomy Research (ICRAR), astronomers have found a powerful black hole, named MQ1, in the nearby galaxy M83. Previously, astronomers have located several compressed objects that are as powerful as MQ1, but have not been able to determine the size of the black hole contained within them until now.
Using several telescopes, the astronomers found that the MQ1 system is a standard-sized small black hole, as opposed to a somewhat larger version that was hypothesized to account for all its power.
“MQ1 is classed as a microquasar - a black hole surrounded by a bubble of hot gas, which is heated by two jets just outside the black hole, powerfully shooting out energy in opposite directions, acting like cosmic sandblasters pushing out on the surrounding gas,” noted team leader Dr. Roberto Soria, who is part of ICRAR, in a statement.
“The significance of the huge jet power measured for MQ1 goes beyond this particular galaxy: it helps astronomers understand and quantify the strong effect that black hole jets have on the surrounding gas, which gets heated and swept away,” he added.
According to astronomers, the most powerful microquasar in the Milky Way, called SS433, is approximately 10 times less powerful than MQ1.
With the help of NASA’s Hubble Space Telescope, astronomers determined that the jets around the MQ1 structure extend approximately 20 light years from either side of the black hole.
MQ1 is a stellar-mass black hole, meaning that it is less than approximately 70 times the mass of our Sun, and was likely formed when a star died, collapsing to leave behind a compact mass. NASA notes that stellar-mass black holes usually weigh between five and ten times the mass of our Sun.
The finding of MQ1 and its features is just one of the discoveries of the exhaustive study of galaxy M83.

WHAT DO YOU KNOW ABOUT MANCHESTER UNITED?
Manchester United Football Club is an English professional football club, based in Old Trafford, Greater Manchester, that plays in the Premier League. Founded as Newton Heath LYR Football Club in 1878, the club changed its name to Manchester United in 1902 and moved to Old Trafford in 1910.
The 1958 Munich air disaster claimed the lives of eight players. In 1968, under the management of Matt Busby, Manchester United was the first English football club to win the European Cup. The current manager, Sir Alex Ferguson, has won 24 major honours since he took over in November 1986.
Manchester United has won many trophies in English football, including a record 19 league titles, a record 11 FA Cups, four League Cups and a record 19 FA Community Shields. The club has also won three European Cups, one UEFA Cup Winners' Cup, one UEFA Super Cup, one Intercontinental Cup and one FIFA Club World Cup. In 1998-99, the club won a Treble of the Premier League, the FA Cup and the UEFA Champions League, an unprecedented feat for an English club.
The club crest is derived from the Manchester City Council coat of arms, although all that remains of it on the current crest is the ship in full sail. The devil stems from the club's nickname "The Red Devils"; it was included on club programmes and scarves in the 1960s, and incorporated into the club crest in 1970, although the crest was not included on the chest of the shirt until 1971 (unless the team was playing in a Cup Final).
A photograph of the Newton Heath team, taken in 1892, is believed to show the players wearing red-and-white quartered jerseys and blue shorts. Between 1894-96, the players wore distinctive green and gold jerseys which were replaced in 1896 by white shirts, which were worn with blue shorts.[After its name change 1902, the club colours were changed to red shirts, white shorts, and black socks, which has become the standard Manchester United home kit. Very few changes were made to the kit until 1922 when the club adopted white shirts bearing a deep red "V" around the neck, similar to the shirt worn in the 1909 FA Cup Final. They remained part of their home kits until 1927. In 1934, players sported cherry and white hooped shirts, but the following season the red shirt was recalled after the club's lowest ever league placing of 20th in the Second Division. The black socks were changed to white from 1959 to 1965, where they were replaced with red socks up until 1971, when the club reverted to black. The current home kit is a red gingham-pattern shirt with dark red checks and a black v-neck collar, worn with white shorts and black socks.
