This dream-like Picture of the Week features the galaxy known as NGC 3156. It is a lenticular galaxy, meaning that it falls somewhere between an elliptical and a spiral galaxy. It lies about 73 million light-years from Earth, in the minor equatorial constellation Sextans.

Sextans is a small constellation that belongs to the Hercules family of constellations. It itself is a constellation with an astronomical theme, being named for the instrument known as the sextant. Sextants are often thought of as navigational instruments that were invented in the 18th century. However, the sextant as an astronomical tool has been around for much longer than that: Islamic scholars developed astronomical sextants many hundreds of years earlier in order to measure angles in the sky. A particularly striking example is the enormous sextant with a radius of 36 metres that was developed by Ulugh Beg of the Timurid dynasty in the fifteenth century, located in Samarkand in present-day Uzbekistan. These early sextants may have been a development of the quadrant, a measuring device proposed by Ptolemy. A sextant, as the name suggests, is shaped like one-sixth of a circle, approximately the shape of the constellation.

Sextants are no longer in use in modern astronomy, having been replaced by instruments that are capable of measuring the positions of stars and astronomical objects much more accurately and precisely. NGC 3156 has been studied in many ways other than determining its precise position — from its cohort of globular clusters, to its relatively recent star formation, to the stars that are being destroyed by the supermassive black hole at its centre.

[Image Description: A large elliptical galaxy. It appears to be formed of faint, grey, concentric ovals that grow progressively brighter towards the core, where there is a very bright point, and fade away at the edge. Two threads of dark red dust cross the galaxy’s disc, near the centre. The background is black and mostly empty, with only a few point stars and small galaxies.]

Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this 1/3 degree wide field of view spans over 30 light-years. The sharp composite, color image highlights faint details of the region’s gas and dust clouds against a backdrop of central Milky Way stars. Stellar winds and energetic light from hot, massive stars formed from M17’s stock of cosmic gas and dust have slowly carved away at the remaining interstellar material, producing the cavernous appearance and undulating shapes. M17 is also known as the Omega Nebula or the Swan Nebula.

Comet Nishimura is growing. More precisely, the tails C/2023 P1 (Nishimura) are growing as it nears the Sun. Discovered only last month, the comet is already near naked eye brightness as it now moves inside the Earth’s orbit. The comet will be nearest the Earth next week, but nearest the Sun the week after — on September 17. Speculation holds that expelled ice and dust from Comet Nishimura‘s last visit to the inner Solar System may have created the Sigma Hydrids meteor shower which peaks yearly in December. If so, then this meteor shower may become more active, refreshed with new comet debris. Pictured, Comet Nishimura was captured from Edgewood, New Mexico, USAfour nights ago, showing a long ion tail structured by interactions with the Sun’s wind. Look for this comet near your eastern horizon just before sunrise for the next few mornings, but very near your western horizon just after sunset next week — as its coma continues to brighten and its tails continue to grow.

Otis Ray Redding Jr. (September 9, 1941 – December 10, 1967 Dawson, GA) was an American singer and songwriter. He is regarded as one of the greatest singers in the history of American popular music and a seminal artist in soul music and rhythm and blues. Nicknamed the “King of Soul“, Redding’s style of singing gained inspiration from the gospel music that preceded the genre. His singing style influenced many other soul artists of the 1960s.

Redding was born in Dawson, Georgia, and at age two, moved to Macon. Redding quit school at age 15 to support his family, working with Little Richard‘s backing band, the Upsetters, and by performing in talent shows at the historic Douglass Theatre in Macon. In 1958, he joined Johnny Jenkins‘s band, the Pinetoppers, with whom he toured the Southern states as a singer and driver. An unscheduled appearance on a Staxrecording session led to a contract and his first hit single, “These Arms of Mine“, in 1962.

Stax released Redding’s debut album, Pain in My Heart, two years later. Initially popular mainly with African-Americans, Redding later reached a wider American pop music audience. Along with his group, he first played small shows in the American South. Redding later performed at the popular Los Angeles night club Whisky a Go Go and toured Europe, performing in London, Paris and other major cities. He also performed at the Monterey Pop Festival in 1967.

Shortly before his death in a plane crash, Redding wrote and recorded his iconic “(Sittin’ On) The Dock of the Bay” with Steve Cropper. The song became the first posthumous number-one record on both the BillboardHot 100 and R&B charts. The album The Dock of the Bay was the first posthumous album to reach number one on the UK Albums Chart. Redding’s premature death devastated Stax. Already on the verge of bankruptcy, the label soon discovered that the Atco division of Atlantic Records owned the rights to his entire song catalog.

Redding received many posthumous accolades, including two Grammy Awards, the Grammy Lifetime Achievement Award and induction into the Rock and Roll Hall of Fame, the Black Music & Entertainment Walk of Fame, and the Songwriters Hall of Fame. In addition to “(Sittin’ On) The Dock of the Bay”, “Respect” and “Try a Little Tenderness” are among his best-known songs. On December 9th 1967 Redding died in a plane crash near Madison, WI at age 26.
