Some 4 billion light-years away, massive galaxy cluster Abell 370 is captured in this sharp Hubble Space Telescope snapshot. The cluster of galaxies only appears to be dominated by two giant elliptical galaxies and infested with faint arcs. In reality, the fainter, scattered bluish arcs, along with the dramatic dragon arc below and left of center, are images of galaxies that lie far beyond Abell 370. About twice as distant, their otherwise undetected light is magnified and distorted by the cluster’s enormous gravitational mass, overwhelmingly dominated by unseen dark matter. Providing a tantalizing glimpse of galaxies in the early universe, the effect is known as gravitational lensing. A consequence of warped spacetime, lensing was predicted by Einstein almost a century ago. Far beyond the spiky foreground Milky Way star at lower right, Abell 370 is seen toward the constellation Cetus, the Sea Monster. It was the last of six galaxy clusters imaged in the Frontier Fields project.

Neil Ellwood Peart OC (/pɪərt/; September 12, 1952 – January 7, 2020) was a Canadian and American musician, best known as the drummer and primary lyricist of the rock band Rush. Peart earned numerous awards for his musical performances, including an induction into the Modern Drummer Readers Poll Hall of Fame in 1983 at the age of thirty, making him the youngest person ever so honoured. He was known to fans by the nickname ‘The Professor’. His drumming was renowned for its technical proficiency and his live performances for their exacting nature and stamina.

Peart was born in Hamilton, Ontario, and grew up in Port Dalhousie (now part of St. Catharines). During adolescence, he floated between regional bands in pursuit of a career as a full-time drummer. After a discouraging stint in England, Peart returned home to concentrate on music where he joined Rush, a Toronto band, in mid-1974, six years after its formation. Together they released nineteen studio albums, with ten exceeding a million copies sold in the United States. Billboard lists the band third in “most consecutive gold or platinum albums by a rock band”.

Early in his career, Peart’s performance style was deeply rooted in hard rock. He drew most of his inspiration from drummers such as Keith Moon, Ginger Baker, and John Bonham, players who at the time were at the forefront of the British hard rock scene. As time passed, he began to emulate jazz and big band musicians Gene Krupa and Buddy Rich. In 1994, Peart became a friend and pupil of jazz instructor Freddie Gruber. It was during this time that Peart revamped his playing style by incorporating jazz and swing components.

In addition to serving as Rush’s primary lyricist, Peart published several memoirs about his travels. His lyrics for Rush addressed universal themes and diverse subjects including science fiction, fantasy, and philosophy, as well as secular, humanitarian, and libertarian themes. Peart wrote a total of seven nonfiction books focused on his travels and personal stories. He also coauthored with Kevin J. Anderson three steampunk fantasy novels based on Rush’s final album, Clockwork Angels. The two also wrote a dark fantasy novella, Drumbeats, inspired by Peart’s travels in Africa.

Peart announced his retirement from touring in an interview with Drumhead Magazine in December 2015. In January 2018, bandmate Alex Lifeson confirmed that Rush had disbanded also due to Peart’s health issues. During his last years Peart lived in Santa Monica, California, with his wife, Carrie Nuttall, and daughter. After a three and a half year illness, Peart died of glioblastoma on January 7, 2020, at age 67.

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.
