The Cosmos with NGC 1052-DF2

March 31, 2018

An international team of researchers using the NASA/ESA Hubble Space Telescope and several other observatories have, for the first time, uncovered a galaxy in our cosmic neighbourhood that is missing most — if not all — of its dark matter. This discovery of the galaxy NGC 1052-DF2 challenges currently-accepted theories of and galaxy formation and provides new insights into the nature of dark matter. The results are published in Nature.

Astronomers using Hubble and several ground-based observatories have found a unique astronomical object: a galaxy that appears to contain almost no dark matter. Hubble helped to accurately confirm the distance of NGC 1052-DF2 to be 65 million light-years and determined its size and brightness. Based on these data the team discovered that NGC 1052-DF2 larger than the Milky Way, but contains about 250 times fewer stars, leading it to be classified as an ultra diffuse galaxy.

“I spent an hour just staring at this image,” lead researcher Pieter van Dokkum of Yale University says as he recalls first seeing the Hubble image of NGC 1052-DF2. “This thing is astonishing: a gigantic blob so sparse that you see the galaxies behind it. It is literally a see-through galaxy.”

Further measurements of the dynamical properties of ten globular clusters orbiting the galaxy allowed the team to infer an independent value of the galaxies mass. This mass is comparable to the mass of the stars in the galaxy, leading to the conclusion that NGC 1052-DF2 contains at least 400 times less dark matter than astronomers predict for a galaxy of its mass, and possibly none at all . This discovery is unpredicted by current theories on the distribution of dark matter and its influence on galaxy formation.

Red Norvo Day

March 31, 2018

Red Norvo (born Kenneth Norville, March 31, 1908 – April 6, 1999) was one of jazz‘s early vibraphonists, known as “Mr. Swing”. He helped establish the xylophone, marimba, and vibraphone as jazz instruments. His recordings included “Dance of the Octopus”, “Bughouse”, “Knockin’ on Wood”, “Congo Blues”, and “Hole in the Wall”.

Red Norvo was born in Beardstown, Illinois. His career began in Chicago with a band called “The Collegians” in 1925. He played with many other bands, including an all-marimba band on the vaudeville circuit, and the bands of Paul Whiteman, Benny Goodman, Charlie Barnet, and Woody Herman. He recorded with Mildred Bailey (his wife), Billie Holiday, Dinah Shore and Frank Sinatra. Norvo and his wife were known as “Mr. and Mrs. Swing.” He appeared as himself in the film Screaming Mimi (1958) and in Ocean’s 11, accompanying Dean Martin while he sang “Ain’t That a Kick in the Head?“.

Freddie Green Day

March 31, 2018

Frederick William Green (March 31, 1911 – March 1, 1987) was an American swing jazz guitarist who played rhythm guitar with the Count Basie Orchestra for almost fifty years.

Green was born in Charleston, South Carolina on March 31, 1911. He was exposed to music from an early age, and learned the banjo before picking up the guitar in his early teenage years. A friend of his father by the name of Sam Walker taught a young Freddie to read music, and keenly encouraged him to keep up his guitar playing. Walker gave Freddie what was perhaps his first gig, playing with a local community group with whom Walker was an organizer. Another member of the group was William “Cat” Anderson, who went on to become an established trumpeter, working with notable figures such as Duke Ellington.

The Cosmos with NGC 247

March 30, 2018

About 70,000 light-years across, NGC 247 is a spiral galaxy smaller than our Milky Way. Measured to be only 11 million light-years distant it is nearby though. Tilted nearly edge-on as seen from our perspective, it dominates this telescopic field of view toward the southern constellation Cetus. The pronounced void on one side of the galaxy’s disk recalls for some its popular name, the Needle’s Eye galaxy. Many background galaxies are visible in this sharp galaxy portrait, including the remarkable string of four galaxies just below and left of NGC 247 known as Burbidge’s Chain. Burbidge’s Chain galaxies are about 300 million light-years distant. The deep image even reveals that the two leftmost galaxies in the chain are apparently interacting, joined by a faint bridge of material. NGC 247 itself is part of the Sculptor Group of galaxies along with the shiny spiral NGC 253.

Eric Clapton Day

March 30, 2018

Eric Patrick Clapton, CBE (born 30 March 1945), is an English rock and blues guitarist, singer, and songwriter. He is the only three-time inductee to the Rock and Roll Hall of Fame: once as a solo artist and separately as a member of the Yardbirds and of Cream. Clapton has been referred to as one of the most important and influential guitarists of all time. Clapton ranked second in Rolling Stone magazine’s list of the “100 Greatest Guitarists of All Time and fourth in Gibson’s “Top 50 Guitarists of All Time”. He was also named number five in Time magazine’s list of “The 10 Best Electric Guitar Players” in 2009.

In the mid-1960s Clapton left the Yardbirds to play with John Mayall & the Bluesbreakers. Immediately after leaving Mayall, Clapton formed the power trio Cream with drummer Ginger Baker and bassist Jack Bruce, in which Clapton played sustained blues improvisations and “arty, blues-based psychedelic pop”.After Cream broke up, he formed blues rock band Blind Faith with Baker, Steve Winwood, and Ric Grech. Clapton’s solo career began in the 1970s, where his work bore the influence of the mellow style of J. J. Cale and the reggae of Bob Marley. His version of Marley’s “I Shot the Sheriff” helped reggae reach a mass market. Two of his most popular recordings were “Layla“, recorded with Derek and the Dominos; and Robert Johnson‘s “Crossroads“, recorded with Cream. Following the death of his son Conor in 1991, Clapton’s grief was expressed in the song “Tears in Heaven“, which was featured on his Unplugged album.

The Cosmos with NGC 2023

March 29, 2018

Carved by a bright young star in Orion’s dusty molecular clouds, NGC 2023 is often overlooked in favor of the nearby dramatic silhouette of the Horsehead Nebula. In its own right it is seen as a beautiful star forming emission and reflection nebula though, a mere 1500 light-years distant. Surprisingly colorful and complex filaments are detailed in this rare NGC 2023 portrait. Scattered points of emission are also from the region’s Herbig-Haro objects, associated with the energetic jets from newborn stars. The sharp telescopic view spans about 10 light-years at the estimated distance of NGC 2023. Off the right edge of the frame lies the more familiar cosmic Horsehead.

Michael Brecker Day

March 29, 2018

Michael Leonard Brecker (March 29, 1949 – January 13, 2007) was an American jazz saxophonist and composer. He was awarded 15 Grammy Awards as both performer and composer. He was awarded an Honorary Doctorate from Berklee College of Music in 2004, and was inducted into the Down Beat Jazz Hall of Fame in 2007.

Michael Brecker was born in Philadelphia and raised in Cheltenham Township, a local suburb. His father Bob (Bobby) was a lawyer who played jazz piano and his mother Sylvia was a portrait artist. Michael Brecker was exposed to jazz at an early age by his father. He grew up as part of the generation of jazz musicians who saw rock music not as the enemy but as a viable musical option. Brecker began studying clarinet at age 6, then moved to alto saxophone in eighth grade, settling on the tenor saxophone as his primary instrument in his sophomore year. He graduated from Cheltenham High School in 1967 and after a year at Indiana University he moved to New York City in 1969, where he carved out a niche for himself as a dynamic and exciting jazz soloist. He first made his mark at age 20 as a member of the jazz-rock band Dreams–a band that included his older brother, trumpeter Randy Brecker, trombonist Barry Rogers, drummer Billy Cobham, keyboardist Jeff Kent and bassist Doug Lubahn. Dreams was short-lived, lasting only from 1969 through 1972, but Miles Davis was seen at some gigs prior to his recording Jack Johnson.

The Cosmos with NGC 7252

March 28, 2018

NGC 7252 is a peculiar galaxy resulting from an interaction between two galaxies that started a billion years ago. It is located 220 million light years away in the constellation Aquarius. It is also called Atoms for Peace galaxy, a nickname which comes from its loop-like structure, made of stars, that resembles a diagram of an electron orbiting an atomic nucleus.

NGC 7252 is located in the southern part of Aquarius. With an apparent magnitude of 12.7, it is bright enough to be seen by amateur astronomers as a faint small fuzzy blob. Large loops of gas and stars around it makes the galaxy quite peculiar. Thus, it is also Arp 226 (the 226th entry in Arp’s list of peculiar galaxies).

In December 1953, U.S. President Dwight D. Eisenhower gave the “Atoms for Peace” speech. The speech was concerned about promoting nuclear power for peaceful purposes instead of nuclear weapons. Significant to the scientific community, the name of the speech was given to this peculiar galaxy. The two galaxies merging also resembles nuclear fusion and the galaxies giant loops resemble a diagram of electrons orbiting the nucleus of an atom.

The galaxy is the result of a collision of two galaxies. This collision is an opportunity for astronomers to study such mergers and to predict the future of our Milky Way after its expected collision with the Andromeda galaxy.

X-ray emissions were observed in NGC 7252. This suggests the existence of nuclear activity or an intermediate-mass black hole in the galaxy.
