Just a few hundred million years ago, NGC 2936, the upper of the two large galaxies shown at the bottom, was likely a normal spiral galaxy — spinning, creating stars — and minding its own business. But then it got too close to the massive elliptical galaxy NGC 2937, just below, and took a turn. Sometimes dubbed the Hummingbird Galaxy for its iconic shape, NGC 2936 is not only being deflected but also being distorted by the close gravitational interaction. Behind filaments of dark interstellar dust, bright blue stars form the nose of the hummingbird, while the center of the spiral appears as an eye. Alternatively, the galaxy pair, together known as Arp 142, look to some like Porpoise or a penguin protecting an egg. The featured re-processed image showing Arp 142 in great detail was taken recently by the Hubble Space Telescope. Arp 142 lies about 300 million light years away toward the constellation of the Water Snake (Hydra). In a billion years or so the two galaxies will likely merge into one larger galaxy.

George Gershwin (/ˈɡɜːrʃ.wɪn/; born Jacob Gershwine; September 26, 1898 – July 11, 1937) was an American composer and pianist whose compositions spanned popular, jazz and classical genres. Among his best-known works are the orchestral compositions Rhapsody in Blue (1924) and An American in Paris(1928), the songs “Swanee” (1919) and “Fascinating Rhythm” (1924), the jazz standards “Embraceable You” (1928) and “I Got Rhythm” (1930), and the opera Porgy and Bess (1935), which included the hit “Summertime“.

Gershwin studied piano under Charles Hambitzer and composition with Rubin Goldmark, Henry Cowell, and Joseph Brody. He began his career as a song plugger but soon started composing Broadway theater works with his brother Ira Gershwin and with Buddy DeSylva. He moved to Paris, intending to study with Nadia Boulanger, but she refused him, afraid that rigorous classical study would ruin his jazz-influenced style; Maurice Ravel voiced similar objections when Gershwin inquired about studying with him. He subsequently composed An American in Paris, returned to New York City and wrote Porgy and Bess with Ira and DuBose Heyward. Initially a commercial failure, it came to be considered one of the most important American operas of the twentieth century and an American cultural classic.

Gershwin moved to Hollywood and composed numerous film scores. He died in 1937, only 38 years old, of a brain tumor.

His compositions have been adapted for use in film and television, with many becoming jazz standards.

This Hubble Picture of the Week includes the pithily-named galaxy SDSS J103512.07+461412.2, visible in the centre of this image as a dispersed sweep of dust and stars with a denser, brighter core. SDSS J103512.07+461412.2 is located 23 million light-years from Earth in the constellation Ursa Major. The seemingly rambling name is because this galaxy was observed as part of the Sloan Digital Sky Survey (SDSS), a massive survey that began in 2000 with the aim of observing and cataloguing vast numbers of astronomical objects. So far, it has recorded several hundred million astronomical objects.

In the early days of astronomy catalogues, astronomers painstakingly recorded individual objects one by one. As an example, the Messier catalogue includes only 110 objects, identified by the astronomer Charles Messier because they were all getting in the way of his comet-hunting efforts. As the Messier catalogue is so limited, it is sufficient to simply refer to those objects as M1 to M110. In contrast, when a survey as massive in scope as the SDSS is involved, and when huge volumes of data need to be processed in an automated manner, the names assigned to objects need to be both longer, and more informative.

To that end, every SDSS object has a designation that follows the format of: ‘SDSS J’, followed by the right ascension (RA), and then the declination (Dec). RA and Dec define the position of an astronomical object in the night sky. RA is analogous to longitude here on Earth, whilst the Dec corresponds to latitude. To be more exact, RA measures the longitudinal distance of an astronomical object from the point where the celestial equator (the mid-point between the north and south celestial poles) intersects with the ecliptic (the plane in which Earth orbits around the Sun). The entire night sky is then carved into 24 slices, known as ‘hours’, measured eastwards from that starting point (which is designated as zero hour). This means that the RA can be expressed in ‘hours’, ‘minutes’ and ‘seconds’. Dec is the angle north or south of the celestial equator, and is expressed in degrees. The RA and Dec of the objects featured in each Hubble Picture of the Week can be found on the lower right side of the webpage!

Thus, the SDSS J103512.07+461412.2 name simply tells us that the galaxy can be found 10 hours, 35 minutes and 12 seconds east of the zero-hour point on the celestial equator, and just over 46 degrees to the north of the celestial equator. So that lengthy name is really an identifier and a detailed location in one!

A wide and very flat spiral galaxy, and one star with four prominent diffraction spikes, are noticeable. The galaxy itself is a broad horizontal streak of tiny stars, extending left and right from a dense and bright core of stars in the centre.]

Dmitri Dmitriyevich Shostakovich (25 September [O.S. 12 September] 1906 – 9 August 1975) was a Soviet-era Russian composer and pianist who became internationally known after the premiere of his First Symphony in 1926 and was regarded throughout his life as a major composer.

Shostakovich achieved early fame in the Soviet Union, but had a complex relationship with its government. His 1934 opera Lady Macbeth of Mtsensk was initially a success, but eventually was condemned by the Soviet government, putting his career at risk. In 1948 his work was denounced under the Zhdanov Doctrine, with professional consequences lasting several years. Even after his censure was rescinded in 1956, performances of his music were occasionally subject to state interventions, as with his Thirteenth Symphony(1962). Shostakovich was a member of the Supreme Soviet of the RSFSR (1947) and the Supreme Soviet of the Soviet Union (from 1962 until his death), as well as chairman of the RSFSR Union of Composers (1960–1968). Over the course of his career, he earned several important awards, including the Order of Lenin, from the Soviet government.

Shostakovich combined a variety of different musical techniques in his works. His music is characterized by sharp contrasts, elements of the grotesque, and ambivalent tonality; he was also heavily influenced by neoclassicism and by the late Romanticism of Gustav Mahler. His orchestral works include 15 symphoniesand six concerti (two each for piano, violin, and cello). His chamber works include 15 string quartets, a piano quintet, and two piano trios. His solo piano works include two sonatas, an early set of 24 preludes, and a later set of 24 preludes and fugues. Stage works include three completed operas and three ballets. Shostakovich also wrote several song cycles, and a substantial quantity of music for theatre and film.

Shostakovich’s reputation has continued to grow after his death. Scholarly interest has increased significantly since the late 20th century, including considerable debate about the relationship between his music and his attitudes toward the Soviet government.
