This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core, known as an active galactic nucleus (AGN), so it is referred to as an active galaxy. Even more specifically, it is categorised as a Type-2 Seyfert galaxy. Seyfert galaxies host one of the most common subclasses of AGN, alongside quasars. Whilst the precise categorisation of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby ones where the host galaxy remains plainly detectable alongside its central AGN, while quasars are invariably very distant AGNs whose incredible luminosities outshine their host galaxies.
There are further subclasses of both Seyfert galaxies and quasars. In the case of Seyfert galaxies, the predominant subcategories are Type-1 and Type-2. These are differentiated from one another by their spectra — the pattern that results when light is split into its constituent wavelengths — where the spectral lines that Type-2 Seyfert galaxies emit are particularly associated with specific so-called ‘forbidden’ emission. To understand why emitted light from a galaxy could be considered forbidden, it helps to understand why spectra exist in the first place. Spectra look the way they do because certain atoms and molecules will absorb and emit light very reliably at very specific wavelengths. The reason for this is quantum physics: electrons (the tiny particles that orbit the nuclei of atoms and molecules) can only exist at very specific energies, and therefore electrons can only lose or gain very specific amounts of energy. These very specific amounts of energy correspond to certain light wavelengths being absorbed or emitted.
Forbidden emission lines, therefore, are spectral emission lines that should not exist according to certain rules of quantum physics. But quantum physics is complex, and some of the rules used to predict it use assumptions that suit laboratory conditions here on Earth. Under those rules, this emission is ‘forbidden’ — so improbable that it’s disregarded. But in space, in the midst of an incredibly energetic galactic core, those assumptions don’t hold anymore, and the ‘forbidden’ light gets a chance to shine out towards us.
[Image Description: A spiral galaxy. It appears to be almost circular and seen face-on, with two prominent spiral arms winding out from a glowing core. It is centred in the frame as if a portrait. Most of the background is black, with only tiny, distant galaxies, but there are two large bright stars in the foreground, one blue and one red, directly above the galaxy.]

His songwriting partnership with the band’s lead vocalist Mick Jagger is one of the most successful in history. His career spans over six decades, and his guitar playing style has been a trademark of the Rolling Stones throughout the band’s career. Richards gained press notoriety for his romantic involvements and illicit drug use, and he was often portrayed as a countercultural figure. First professionally known as Keith Richard, by the early 1970s he had fully asserted his family name.
Richards was born in and grew up in Dartford, Kent. He studied at the Dartford Technical School and Sidcup Art College. After graduating, Richards befriended Jagger, Bill Wyman, Charlie Watts, and Brian Jones and joined the Rolling Stones. As a member of the Rolling Stones, Richards also sings lead on some Stones songs. Richards typically sings lead on at least one song a concert, including “Happy“, “Before They Make Me Run“, and “Connection“. Outside of his career with the Rolling Stones, Richards has also played with his own side-project, The X-Pensive Winos. He also appeared in three Pirates of the Caribbeanfilms as Captain Teague, father of Jack Sparrow, whose look and characterisation was inspired by Richards himself.
In 1989, Richards was inducted into the Rock and Roll Hall of Fame and in 2004 into the UK Music Hall of Fame with the Rolling Stones. Rolling Stone magazine ranked him fourth on its list of 100 best guitarists in 2011. In 2023, Rolling Stone’s ranking was 15th. The magazine lists fourteen songs that Richards wrote with Jagger on its “500 Greatest Songs of All Time” list.

Smith was born in Leland, Mississippi, United States. He started out playing drums, mellophone, and French horn before he settled on the trumpet. He played in various R&B groups and, by 1967, became a member of the AACM and co-founded the Creative Construction Company, a trio with Leroy Jenkins and Anthony Braxton. In 1971, Smith formed his own label, Kabell. He also formed another band, the New Dalta Ahkri, with members including Henry Threadgill, Anthony Davisand Oliver Lake.

Land developed his hard bop playing with the Max Roach/Clifford Brown band into a personal, modern style, often rivalling Clifford Brown’s instrumental ability with his own inventive and whimsical solos. His tone was strong and emotional, yet hinted at a certain introspective fragility.
Land was born in Houston, Texas, United States and grew up in San Diego, California. He started playing at the age of 16. He made his first recording as the leader of the Harold Land All-Stars, for Savoy Recordsin 1949. In 1954, he joined the Clifford Brown/Max Roach Quintet, with whom he was at the forefront of the hard-bop/bebop movement. The Land family moved from San Diego to Los Angeles, in 1955. There he played with Curtis Counce, led his own groups, and co-led groups with Bobby Hutcherson, Blue Mitchell, and Red Mitchell. From the 1970s onwards, his style showed the influence of John Coltrane.

He was nicknamedCleanhead after an incident in which his hair was accidentally destroyed by lye contained in a hair straightening product, necessitating shaving it off; enamoured of the look, Vinson maintained a shaved head thereafter. Music critic Robert Christgau has called Vinson “one of the cleanest—and nastiest—blues voices you’ll ever hear.”
Vinson was born in Houston, Texas. He was a member of the horn section in Milton Larkin‘s orchestra, which he joined in the late 1930s. At various times, he sat next to Arnett Cobb, Illinois Jacquet, and Tom Archia, while other members of the band included Cedric Haywood and Wild Bill Davis. After exiting Larkin’s employment in 1941, Vinson picked up a few vocal tricks while on tour with bluesman Big Bill Broonzy. He then moved to New York and joined the Cootie Williams Orchestra from 1942 to 1945, recording such tunes as “Cherry Red”. Vinson struck out on his own in 1945, forming his own large band, signing with Mercury Records, and enjoying a double-sided hit in 1947 with his R&B chart-topper “Old Maid Boogie”, and the song that would prove to be his signature number, “Kidney Stew Blues”.

It is a H II region of notable extension with an oval shape and crossed in a northwest-southeast direction by a dark band that divides it apparently in two equal parts: the eastern part is dominated by the presence of a small open cluster, known as Berkeley 90, with which it is physically associated, while the western part lies in the direction of the star variable α2 CVn a> is just 148 Sun however, the distance of this star from the equal to 5.63;average apparent magnitude HD 196178 (V2015 Cyg), of (481 light years), significantly lower than that estimated for the nebula, about 2300 parsec (7500 light years). The stars responsible for the ionization of gases are LS III +46 12, of spectral class O6III, DM46 2972, of class O9.5V, and DM46 2978, of class B0III; the first of these dominates the Berkeley 90 cluster. The star BD+46 2972 also appears in the same field, whose distance is however larger than the nebula, therefore a physical relationship with it would be excluded.

Recognized for his innovative style, which featured a highly syncopated, broken triplet pattern on the hi-hat, and for his dazzling drum introductions, Barrett’s prolific recordings with Marley have been internationally celebrated. He is credited with popularising the One Drop rhythm.
Carlton Barrett was born in Kingston, Jamaica in 1950, the son of Wilfred and Violet Barrett. As a teenager, he built his first set of drums out of empty paint cans he found on the street. Along with his contemporaries, drummers Sly Dunbar, Leroy “Horsemouth” Wallace, Style Scott and Carlton “Santa” Davis, Barrett was heavily influenced by Lloyd Knibb of The Skatalites.
In the 1960s, Barrett began performing with his brother Aston “Family Man” Barrett, under the names The Soul Mates, The Rhythm Force and eventually The Hippy Boys, a line-up that featured Max Romeo on vocals, Leroy Brown, Delano Stewart, Glen Adams and Alva Lewis. In 1969, the brothers joined The Wailers (later Known as Bob Marley and The Wailers). During his years with Marley, Barrett continued to record for many of Jamaica’s most well known artists and is featured on solo albums by Bunny Wailer (Blackheart Man) and Peter Tosh(Legalize It and Equal Rights) as well as many others. On 17 April 1987, a gunman shot and killed Barrett outside his home at 12 Bridgemount Park Avenue in Kingston, Jamaica. He was 36.

After early training as a classical flautist, he developed an interest in blues harmonica. He explored the blues scene in his native Chicago, where he met Muddy Waters and other blues greats, who provided encouragement and opportunities for him to join in jam sessions. He soon began performing with fellow blues enthusiasts Nick Gravenites and Elvin Bishop.
In 1963, he formed the Paul Butterfield Blues Band, which recorded several successful albums and was popular on the late-1960s concert and festival circuit, with performances at the Fillmore West in San Francisco, the Fillmore East in New York City, the Monterey Pop Festival, and Woodstock. The band was known for combining electric Chicago blues with a rock urgency and for their pioneering jazz fusionperformances and recordings. The band was also among the first racially integrated blues groups. After the breakup of the group in 1971, Butterfield continued to tour and record with the band Paul Butterfield’s Better Days, with his mentor Muddy Waters, and with members of the roots-rock group the Band. While still recording and performing, Butterfield died in 1987 at age 44 of an accidental drug overdose.
Music critics have acknowledged his development of an original approach that places him among the best-known blues harp players. In 2006, he was inducted into the Blues Hall of Fame. Butterfield and the early members of the Paul Butterfield Blues Band were inducted into the Rock and Roll Hall of Fame in 2015. Both panels noted his harmonica skills and his contributions to bringing blues music to a younger and broader audience. On May 4, 1987, at age 44, Paul Butterfield died at his apartment in the North Hollywood district of Los Angeles. An autopsy by the county coroner concluded that he was the victim of an accidental drug overdose, with “significant levels of morphine (heroin), … codeine, the tranquilizer Librium and a trace of alcohol.

James Carroll Booker III (December 17, 1939 – November 8, 1983) was an American New Orleans rhythm and blues keyboardist. Flamboyant in personality and style, and possessing extraordinary technical skill on the piano, he was dubbed “the Black Liberace“.
His 1960 recording “Gonzo” reached No. 43 on the Billboard magazine record chart and No. 3 in R&B, and he toured internationally in the 1970s. After being mainly a rhythm and blues artist, Booker later fused this genre with jazz and with popular music such as that of the Beatles, playing these in his signature backbeat. His influence is profound in the New Orleans music scene, where his renditions and originals are most often performed. Booker died aged 43 on November 8, 1983, while seated in a wheelchair in the emergency room at New Orleans’ Charity Hospital, waiting to receive medical attention. The cause of death, as cited in the Orleans Parish Coroner’s Death Certificate, was renal failure related to chronic abuse of heroin and alcohol.

The distance to the galaxy was previously believed to be only 2.4 Mpc (7.8 Mly). However, in 2008 scientists studying images from Hubble calculated the galaxy’s distance at nearly 11 million light-years away, about 4 million light-years farther than previously thought, meaning it is a member of the IC 342 group of galaxies.
