This composite image shows the superbubble DEM L50 (a.k.a. N186) located in the Large Magellanic Cloud about 160,000 light years from Earth. Superbubbles are found in regions where massive stars have formed in the last few million years. The massive stars produce intense radiation, expel matter at high speeds, and race through their evolution to explode as supernovas. The winds and supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. X-rays from NASA’s Chandra X-ray Observatory are shown in pink and optical data from the Magellanic Cloud Emission Line Survey (MCELS) are colored in red, green and blue. The MCELS data were obtained with the University of Michigan’s 0.9-meter Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory (CTIO). The shape of DEM L50 is approximately an ellipse, with a supernova remnant named SNR N186 D located on its northern edge.
Like another superbubble in the LMC, N44, DEM L50 gives off about 20 times more X-rays than expected from standard models for the evolution of superbubbles. A Chandra study published in 2011 showed that there are two extra sources of the bright X-ray emission: supernova shock waves striking the walls of the cavities, and hot material evaporating from the cavity walls.
The Chandra study of DEM L50 was published in the Astrophysical Journal in 2011 and was led by Anne Jaskot from the University of Michigan in Ann Arbor. The Chandra study of DEM L50 was led by Anne Jaskot from the University of Michigan in Ann Arbor. The co-authors were Dave Strickland from Johns Hopkins University in Baltimore, MD, Sally Oey from University of Michigan, You-Hua Chu from University of Illinois and Guillermo Garcia-Segura from Instituto de Astronomia-UNAM in Ensenada, Mexico.

Born in Chicago, Illinois, Ammons studied music with instructor Walter Dyett at DuSable High School. Ammons began to gain recognition while still at high school when in 1943, at the age of 18, he went on the road with trumpeter King Kolax‘s band. In 1944, he joined the band of Billy Eckstine (who bestowed on him the nickname “Jug” when straw hats ordered for the band did not fit), playing alongside Charlie Parker and later Dexter Gordon. Performances from this period include “Blowin’ the Blues Away,” featuring a saxophone duel between Ammons and Gordon. After 1947, when Eckstine became a solo performer, Ammons then led a group, including Miles Davis and Sonny Stitt, that performed at Chicago’s Jumptown Club. In 1949, Ammons replaced Stan Getz as a member of Woody Herman‘s Second Herd, and then in 1950 formed a duet with Sonny Stitt.

Located in the picturesque southern constellation of Centaurus, the Gum 41 nebula takes up most of this image brought to you by the VLT Survey Telescope, hosted at ESO’s Paranal Observatory in Chile. Let’s take a closer look at this intricate structure.
Set against a colorful backdrop of stars, Gum 41 is a pleasantly symmetric example of a Strömgren sphere: a shell of hydrogen gas atoms glowing in rosy hues due to the radiation of the dazzling central star. While this star, called HD 100099, may appear to be one very bright object, it is actually thought to be two young, massive stars orbiting in such a tight embrace that they cannot be separated at the scale of this image.
This romantic region is home to many pairs like this, including the luminous object on the lower right outskirts of the nebula, HD 99944. Sadly, the love story in these stellar couples will have a tragic ending: unlike our Sun, these hot and massive stars tend to have short lifetimes of only a few million years, and eventually there will be no young stars left to make the nebula glow. One day, Gum 41 will fade into transparency and be lost to future astronomers forever.
Gum 41 is also a member of a much larger region, affectionately called the Running Chicken Nebula. Whether Gum 41 forms the foot or the head of the chicken is surprisingly controversial.

He shortly thereafter joined the Miles Davis Quintet, where he helped to redefine the role of a jazz rhythm section and was one of the primary architects of the post-bop sound. In the 1970s, Hancock experimented with jazz fusion, funk, and electrostyles, using a wide array of synthesizers and electronics. It was during this period that he released perhaps his best-known and most influential album, Head Hunters.
Hancock’s best-known compositions include “Cantaloupe Island“, “Watermelon Man“, “Maiden Voyage“, and “Chameleon“, all of which are jazz standards. During the 1980s, he enjoyed a hit single with the electronic instrumental “Rockit“, a collaboration with bassist/producer Bill Laswell. Hancock has won an Academy Award and 14 Grammy Awards, including Album of the Year for his 2007 Joni Mitchell tribute album River: The Joni Letters.
Since 2012, Hancock has served as a professor at the University of California, Los Angeles, where he teaches at the UCLA Herb Alpert School of Music. He is also the chairman of the Herbie Hancock Institute of Jazz (known as the Thelonious Monk Institute of Jazz until 2019).
Hancock was born in Chicago, the son of Winnie Belle (née Griffin), a secretary, and Wayman Edward Hancock, a government meat inspector. His parents named him after the singer and actor Herb Jeffries.He attended Hyde Park High School. Like many jazz pianists, Hancock started with a classical education. He started playing piano when he was seven years old, and his talent was recognized early. Considered a child prodigy, he played the first movement of Mozart‘s Piano Concerto No. 26 in D Major, K. 537 (Coronation) at a young people’s concert on February 5, 1952, with the Chicago Symphony Orchestra (led by CSO assistant conductor George Schick) at age 11.

James D. Harris was born in Earle, Arkansas, and relocated with his family to Chicago, Illinois, at the age of seven. He played in several Chicago blues ensembles in the late 1940s. He also worked as a mechanic and as a professional gambler (his nickname came from a dice players’ expression, “shake ’em”). His debut recording was the single “Call Me if You Need Me”, backed with “Roll Your Moneymaker”, released by Artistic Records in 1958, featuring Magic Sam and Syl Johnson on guitar and produced by Willie Dixon. Harris was not paid for the session, but he won $700 shooting craps with label owner Eli Toscano.
more...Theodore Roosevelt “Hound Dog” Taylor (April 12, 1915 – December 17, 1975) was an American Chicago blues guitarist and singer.
Taylor was born in Natchez, Mississippi, in 1915, though some sources say 1917. He first played the piano and began playing the guitar when he was 20. He moved to Chicago in 1942.
Taylor had a condition known as polydactylism, which resulted in him having six fingers on both hands. As is usual with the condition, the extra digits were rudimentary nubbins and could not be moved. One night, while drunk, he cut off the extra digit on his right hand using a straight razor.
He became a full-time musician around 1957, but remained unknown outside the Chicago area, where he played small clubs in black neighborhoods and at the open-air Maxwell Street Market. He was known for his electrified slide guitar playing (roughly styled after that of Elmore James), his cheap Japanese Teiscoguitars, and his raucous boogie beats. In 1967, Taylor toured Europe with the American Folk Blues Festival, performing with Little Walter and Koko Taylor. Taylor died of lung cancer in 1975. He was buried at Restvale Cemetery, in Alsip, Illinois.
