A spiral galaxy with a secret The NASA/ESA Hubble Space Telescope – with a little help from an amateur astronomer – has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years away, practically a neighbour by cosmic standards, Messier 106 is one of the brightest and nearest spiral galaxies to our own. Despite its appearance, which looks much like countless other galaxies, Messier 106 hides a number of secrets. Thanks to this image, which combines data from Hubble with observations by amateur astronomers Robert Gendler and Jay GaBany, they are revealed as never before. At its heart, as in most spiral galaxies, is a supermassive black hole, but this one is particularly active. Unlike the black hole at the centre of the Milky Way, which pulls in wisps of gas only occasionally, Messier 106’s black hole is actively gobbling up material. As the gas spirals towards the black hole, it heats up and emits powerful radiation. Part of the emission from the centre of Messier 106 is produced by a process that is somewhat similar to that in a laser – although here the process produces bright microwave radiation.^[1] As well as this microwave emission from Messier 106’s heart, the galaxy has another startling feature – instead of two spiral arms, it appears to have four. Although the second pair of arms can be seen in visible light images as ghostly wisps of gas, as in this image, they are even more prominent in observations made outside of the visible spectrum, such as those using X-ray or radio waves. Unlike the normal arms, these two extra arms are made up of hot gas rather than stars, and their origin remained unexplained until recently. Astronomers think that these, like the microwave emission from the galactic centre, are caused by the black hole at Messier 106’s heart, and so are a totally different phenomenon from the galaxy’s normal, star-filled arms. The extra arms appear to be an indirect result of jets of material produced by the violent churning of matter around the black hole. As these jets travel through the galactic matter they disrupt and heat up the surrounding gas, which in turn excites the denser gas in the galactic plane and causes it to glow brightly. This denser gas closer to the centre of the galaxy is tightly-bound, and so the arms appear to be straight. However, the looser disc gas further out is blown above or below the disc in the opposite direction from the jet, so that the gas curves out of the disc — producing the arching red arms seen here. Despite carrying his name, Messier 106 was neither discovered nor catalogued by the renowned 18th century astronomer Charles Messier. Discovered by his assistant, Pierre Méchain, the galaxy was never added to the catalogue in his lifetime. Along with six other objects discovered but not logged by the pair, Messier 106 was posthumously added to the Messier catalogue in the 20th century. Amateur astronomer Robert Gendler retrieved archival Hubble images of M 106 to assemble a mosaic of the centre of the galaxy. He then used his own and fellow astrophotographer Jay GaBany’s observations of M 106 to combine with the Hubble data in areas where there was less coverage, and finally, to fill in the holes and gaps where no Hubble data existed. The centre of the galaxy is composed almost entirely of Hubble data taken by the Advanced Camera for Surveys, Wide Field Camera 3, and Wide Field and Planetary Camera 2 detectors. The outer spiral arms are predominantly HST data colourised with ground-based data taken by Gendler’s and GaBany’s 12.5-inch and 20-inch telescopes, located at very dark remote sites in New Mexico, USA. Gendler was a prizewinner in the recent Hubble’s Hidden Treasures image processing competition. Another prizewinner, André van der Hoeven, entered a different version of Messier 106, combining Hubble and NOAO data.

The centre of M106 harbours a similar phenomenon called a maser (short for microwave amplification by the stimulated emission of radiation), in which microwave radiation, which is at longer wavelengths than visible light, is emitted. Note that unlike man-made lasers, which are designed to produce a narrow beam, astronomical masers shine in all directions.

Mitchell Herbert Ellis (August 4, 1921 – March 28, 2010) was an American jazz guitarist. Perhaps best known for his 1950s membership in the trio of pianist Oscar Peterson, Ellis was also a staple of west-coast studio recording sessions, and was described by critic Scott Yanow as “an excellent bop-based guitarist with a slight country twang to his sound.”

Born in Farmersville, Texas and raised in the suburbs of Dallas, Ellis first heard the electric guitar performed by George Barnes on a radio program. This experience is said to have inspired him to take up the guitar. He became proficient on the instrument by the time he entered North Texas State University. Ellis majored in music, but because they did not yet have a guitar program at that time, he studied the string bass. Unfortunately, due to lack of funds, his college days were short-lived. In 1941, Ellis dropped out of college and toured for six months with a band from the University of Kansas.

Louis Daniel Armstrong (August 4, 1901 – July 6, 1971), nicknamed Satchmo, Satch, and Pops, was an American trumpeter, composer, singer and occasional actor who was one of the most influential figures in jazz. His career spanned five decades, from the 1920s to the 1960s, and different eras in the history of jazz. In 2017, he was inducted into the Rhythm & Blues Hall of Fame.

Armstrong was born and raised in New Orleans. Coming to prominence in the 1920s as an “inventive” trumpet and cornet player, Armstrong was a foundational influence in jazz, shifting the focus of the music from collective improvisation to solo performance. Around 1922, he followed his mentor, Joe “King” Oliver, to Chicago to play in the Creole Jazz Band. In the Windy City, he networked with other jazz musicians, reconnecting with his friend, Bix Beiderbecke, and made new contacts, which included Hoagy Carmichael and Lil Hardin. He earned a reputation at “cutting contests”, and moved to New York in order to join Fletcher Henderson‘s band.

With his instantly recognizable gravelly voice, Armstrong was also an influential singer, demonstrating great dexterity as an improviser, bending the lyrics and melody of a song for expressive purposes. He was also very skilled at scat singing. Armstrong is renowned for his charismatic stage presence and voice almost as much as for his trumpet playing. Armstrong’s influence extends well beyond jazz, and by the end of his career in the 1960s, he was widely regarded as a profound influence on popular music in general. Armstrong was one of the first truly popular African-Americanentertainers to “cross over,” that is, whose skin color became secondary to his music in an America that was extremely racially divided at the time. He rarely publicly politicized his race, often to the dismay of fellow African Americans, but took a well-publicized stand for desegregation in the Little Rock crisis. His artistry and personality allowed him access to the upper echelons of American society, then highly restricted for black men.

Armstrong often stated that he was born on July 4, 1900. Although he died in 1971, it was not until the mid-1980s that his true birth date, August 4, 1901, was discovered by Tad Jones by researching baptismal records. At least three other biographies treat the July 4th birth date as a myth.

Thin, red veins of energized gas mark the location of one of the larger supernova remnants in the Milky Way galaxy in this image from NASA’s Spitzer Space Telescope.

A supernova “remnant” refers to the collective, leftover signs of an exploded star, or supernova. The red filaments in this image belong to a supernova remnant known as HBH 3 that was first observed in 1966 using radio telescopes. Traces of the remnant also radiate optical light. The branches of glowing material are most likely molecular gas that was pummeled by a shockwave generated by the supernova. The energy from the explosion energized the molecules and caused them to radiate infrared light.

The white, cloud-like formation also visible in the image is part of a complex of star-forming regions, simply named W3, W4 and W5. However, those regions extend far beyond the edge of this image. Both the white star-forming regions and the red filaments are approximately 6,400 light years away and lie inside our Milky Way galaxy.

HBH 3 is about 150 light-years in diameter, ranking it amongst the largest known supernova remnants. It is also possibly one of the oldest: Astronomers estimate the original explosion may have happened anywhere from 80,000 to one million years ago.

In 2016, NASA’s Fermi Gamma-Ray Telescope detected very high-energy light — called gamma rays — coming from the region near HBH 3. This emission may be coming from gas in one of the neighboring star-forming regions, excited by powerful particles emitted by the supernova blast.

Roscoe Mitchell (born August 3, 1940) is an American composer, jazz instrumentalist, and educator, known for being “a technically superb – if idiosyncratic – saxophonist”. The Penguin Guide to Jazz described him as “one of the key figures” in avant-garde jazz; All About Jazz states that he has been “at the forefront of modern music” for the past 35 years. Critic Jon Pareles in The New York Times has mentioned that Mitchell “qualifies as an iconoclast”. In addition to his own work as a bandleader, Mitchell is known for cofounding the Art Ensemble of Chicago and the Association for the Advancement of Creative Musicians (AACM).

Mitchell was born in Chicago, Illinois. He also grew up in the Chicago area, where he played saxophone and clarinet at around age twelve. His family was always involved in music with many different styles playing in the house when he was a child as well as having a secular music background. His brother, Norman, in particular was the one who introduced Mitchell to jazz. While attending Englewood High School in Chicago, he furthered his study of the clarinet.

Charles James Shavers (August 3, 1920 – July 8, 1971) was an American swing era jazz trumpeter who played with Dizzy Gillespie, Roy Eldridge, Johnny Dodds, Jimmie Noone, Sidney Bechet, Midge Williams, and Billie Holiday. He was an arranger and composer, and one of his compositions, “Undecided“, is a jazz standard.^[2]

Charlie Shavers’ father (a distant relative of Fats Navarro) was from the prominent Shavers family of Key West, Florida, and Charlie was a cousin of heavyweight boxer Earnie Shavers. Born in New York City, he took up piano and banjo before switching to trumpet.

Eddie Jefferson (August 3, 1918 – May 9, 1979) was a jazz vocalist and lyricist. He is credited as an innovator of vocalese, a musical style in which lyrics are set to an instrumental composition or solo. Jefferson himself claims that his main influence was Leo Watson. Perhaps his best-known song is “Moody’s Mood for Love“, though it was first recorded by King Pleasure, who cited Jefferson as an influence. Jefferson’s songs “Parker’s Mood” and “Filthy McNasty” were also hits.

Jefferson was born in Pittsburgh, Pennsylvania. One of his most notable recordings, “So What“, combined the lyrics of artist Christopher Acemandese Hall with the music of Miles Davis to highlight his skills, and enabled him to turn a phrase, into his style he calls jazz vocalese.

World Music on Flamenco Fridays with Paco de Lucia and Ricardo Modrego

Ricardo Modrego (19 October 1934 – 17 January 2017) was a Spanish flamenco guitarist from Madrid. He was the brother of Spanish-Flamenco dancer Nana Lorca. They both started their careers in Madrid in the early 1950s.

By 1953 the well known brother and sister were under contract to tour South America with Spanish dancer Hurtado de Cordoba. In October 1954 the Cordoba Company debut at the 48th Street Theatre in New York to good reviews and poor ticket sales. The four-week contract played out for only two weeks. The brother and sister team found temporary work in the US but soon returned to Spain. In Madrid they auditioned for Pilar Lopez and joined her company touring in Spain and internationally. Ricardo recorded three albums with a young Paco de Lucia, his first albums, Dos guitarras flamencas (1964), 12 canciones de García Lorca para guitarra and 12 éxitos para 2 guitarras flamencas (1965). In between the records the brother and sister team toured with the Jose Greco Spanish Dance Company. Nana later married Jose Greco and both Greco’s toured the world as famous Spanish-Flamenco dancers. Ricardo also toured with Mariemma and Antonio Ruiz, he joined the Greco’s on tour from time to time. Jose and Nana had one son Paolo Greco, a film music composer. The Greco’s divorced leaving both Nana Lorca and Paolo Greco to live in Madrid.

Juvenal de Holanda Vasconcelos, known as Naná Vasconcelos (2 August 1944 – 9 March 2016), was a Brazilian percussionist, vocalist and berimbau player, notable for his work as a solo artist on over two dozen albums, and as a backing musician with Pat Metheny, Don Cherry, Jan Garbarek, Egberto Gismonti, Gato Barbieri, and Milton Nascimento.

Carl Saunders (born August 2, 1942) is a jazz trumpeter, composer, and educator who has worked with Stan Kenton, Buddy Rich, Bill Holman, and Clare Fischer, in addition to Frank Sinatra, Ella Fitzgerald, Mel Tormé, and Paul Anka.

Born in Indianapolis, Indiana, his first five years were mostly spent on the road. His uncle was trumpeter Bobby Sherwood, who was led the popular Sherwood Orchestra, having hits with “Elks Parade” and “Sherwood’s Forest.” Saunders’s mother Gail (Bobby’s sister) sang for the Sherwood Orchestra and Stan Kenton. When Saunders was five, he and his mother settled in Los Angeles, living with his aunt Caroline and her husband, saxophonist Dave Pell. He heard the records of the Dave Pell Octet and was influenced by the style and phrasing of trumpeter Don Fagerquist.

Bright stars and colorful nebulas glow in one of the galactic arms of Messier 66, an intermediate spiral galaxy located 36 million light-years away in the constellation Leo. Also known as NGC 3627, this galaxy’s structure is somewhere between a barred and unbarred spiral galaxy. Citizen scientist Kevin Gill processed this image using data from the Hubble Space Telescope.

Robert William Cray (born August 1, 1953) is an American blues guitarist and singer. He has led his own band and won five Grammy Awards.

One music journalist noted “If you define ‘blues’ by the rigid categories of structure rather than the flexible language of feeling allusion, Robert Cray… Larry Garner, Joe Louis Walker and James Armstrong are a new and uncategorizable breed, their music blues-like rather than blues, each of them blending ideas and devices from a variety of sources – soul, rock, jazz, gospel – with a sophistication beyond the reach of their forerunners”.

Robert Cray was born on August 1, 1953, in Columbus, Georgia, while his father was stationed at Fort Benning. Cray’s musical beginnings go back to when he was a student at Denbigh High School in Newport News, Virginia. While there, he played in his first band, The One-Way Street. His family eventually settled in the Tacoma, Washington, area. There, he attended Lakes High School in Lakewood, Washington.

Jerome John Garcia (August 1, 1942 – August 9, 1995) was an American singer-songwriter and guitarist, best known for his work as the lead guitarist and as a vocalist with the band Grateful Dead, which came to prominence during the counterculture era in the 1960s. Although he disavowed the role, Garcia was viewed by many as the leader or “spokesman” of the group.

One of its founders, Garcia performed with the Grateful Dead for their entire thirty-year career (1965–1995). Garcia also founded and participated in a variety of side projects, including the Saunders–Garcia Band (with longtime friend Merl Saunders), the Jerry Garcia Band, Old and in the Way, the Garcia/Grisman acoustic duo, Legion of Mary, and the New Riders of the Purple Sage (which Garcia co-founded with John Dawson and David Nelson). He also released several solo albums, and contributed to a number of albums by other artists over the years as a session musician. He was well known for his distinctive guitar playing and was ranked 13th in Rolling Stone‘s “100 Greatest Guitarists of All Time” cover story.

Later in life, Garcia was sometimes ill because of his diabetes, and in 1986, he went into a diabetic coma that nearly cost him his life. Although his overall health improved somewhat after that, he continued to struggle with obesity, smoking, and longstanding heroin and cocaine addictions. He was staying in a California drug rehabilitation facility when he died of a heart attack in August 1995 at the age of 53.

Jerry Garcia’s ancestors on his father’s side were from Galicia in northwest Spain. His mother’s ancestors were Irish and Swedish. He was born in the Excelsior District of San Francisco, California, on August 1, 1942, to Jose Ramon “Joe” Garcia and Ruth Marie “Bobbie” (née Clifford) Garcia, who was herself born in San Francisco.
