Galileo discovers Jupiter's moons
Galileo Galilei's telescopic discovery of Jupiter's moons proved that not all celestial bodies orbit Earth, supporting heliocentrism and opening the question of other worlds. Source — Wikipedia:
Galileo Galilei (1564-1642) A half-length portrait, in old age, of the Italian mathematician, philosopher and astronomer, who was appointed court mathematician to the Medici dukes of Tuscany at Florence in 1610. He is dressed in black, wears a white beard and is seated in a chair holding a telescope in his right hand. His left hand rests on the arm of the chair and he wears a ring with a clear stone on his fourth finger. He faces forward towards the viewer. Galileo, though not first inventor of the refracting telescope in 1609, enhanced its power, which enabled him to see that the Moon had mountains and that Jupiter had satellites. His championship of the Copernican (Sun-centred) planetary system brought him into serious conflict with the Roman Catholic church, which forced him to make a public recantation and put him under restriction in later life, as noted by the poet John Milton, who met him in Florence in 1638 and recorded in his 'Areopagitica': 'There it was I found the famous Galileo, grown old, a prisoner to the Inquisition for thinking in astronomy otherwise than the Franciscan and Dominican licensers thought.' The artist was a Flemish painter and draughtsman who worked in Florence as court painter to the Medici. He was considered the foremost portrait painter in Italy, with a strong interest in Venetian Renaissance art. This is one of the last portraits of Galileo and several versions and/or copies were made. This one, painted for the Florentine Pandolfini family, may be the original, though there are other contenders. The principal evidence is the inscription on the back of the original canvas: 'No 51. / Galileo / da Giusto Sustermans / della Casa Pandolfini / a Firenza', while an old English label on the stretcher adds that it is 'the best known' portrait and 'That in the Pitti Palace is without hands and has all the appearances of a copy'. The longstanding Pitti version (no. 2397), which is otherwise the best known and often assumed to be the original is cut down all round, just showing the rim of the telescope at the bottom. NMM inspection in 1971 also concluded it was more likely to be a copy. The present painting has a near-intact provenance since 1833. It was purchased in Florence on 26 April that year for 534 pauli (£12 10s) including its fine Florentine frame, from the Marchesa Nimini: its previous history is not known, or whether the Marchesa had a family connection with the Pandolfini. The buyer was a long-resident English collector, the Revd John Sanford (d. 1855). He returned with his large collection to England in 1837 and subsequently put much on the market. The Galileo appears as no.51 (as added above the Italian inscription) in an 1838 printed catalogue of Yates, the dealer, with a reserve of £200 but it did not sell. It was exhibited at the British Institution in 1849 and passed with Sanford's remaining collection to his only daughter, who in 1844 married Frederick Methuen (later second Lord Methuen) of Corsham Court, Wiltshire, the whole becoming part of the larger Methuen collection. It was sold from Corsham at Christie's on 14 May 1920 (lot 38, for 58 guineas), the buyer being the 'Art Collections Association' and probably quickly passed to George H. Gabb, though exactly how is unknown. His collection - mainly of scientific instruments - was purchased and presented to the Museum by Sir James Caird early in 1937. At another Christie’s sale in 1920 he also purchased directly, again for 58 guineas, a pear-wood bust of Galileo from the Sanford holdings at Corsham (SCU0023) and was the immediate source of both the Museum’s other two Galileo oil portraits (BHC2699 and BHC2701), and another bust of him in bronze (SCU0022). The good 19th-century catalogues of the Sanford and Methuen collections are still at Corsham and the Sustermans is no 18. in Sanford’s manuscript catalogue raisonnee of 1847. Like much of his collection it was also recorded in a watercolour copy, also still at Corsham, made in Florence about 1835 by Giovanni Gozzini. The oil features in all three printed catalogues of the Methuen collection (c.1876-1903) and hung near the bust in the lower corridor at Corsham for over 45 years preceding its sale. Waagen, who also saw it in the house, briefly described the Sanford collection origins and noted the painting as 'From the Pandolfini family, for whom it was painted. Of lively conception and broad treatment'. ('Galleries and Cabinets of Art in Great Britain', 1857, p. 397). A more complete account is Benedict Nicolson’s well-illustrated 'The Sanford Collection', in the ‘Burlington Magazine’ (vol. 97, no. 628, July 1955, pp. 207-14), though neither he nor Corsham then knew where the painting was and the image included is from the Gozzini watercolour. NMM notes made in Florence in 1971 mention the Pitti having recently acquired another version of BHC2700 from the Rosselli del Turco collection (only then seen as a photograph in the German Art Institute there), but no further mention of this has been found and it may be a misunderstanding: a third was also noted as existing in Frankfurt. A fourth (exhibited at the B.I. in 1854) was in the Lansdowne sale at Christie's on 7 March 1930 and may be the same as that recorded on the RKD database as again passing through Christie's on 7 May 1995 though, curiously, also from the 'Marquis of Lansdowne, Meikleour House'. The last appears to be early and good, with a fragmentary Latin inscription. Nicholson in 1955 also noted one in the Torre al Gallo, Florence, but the present status and relationship of all these is not yet known to the Museum. The Bodleian Library, Oxford, also has an early copy (omitting the left hand) presented by Galileo's disciple, Vincenzo Viviani, in 1661. Confusion is not helped by the fact that two separate Sustermans portraits of Galileo are sometimes treated as versions of each other, whereas they are somewhat different. The earlier one of 1636, in the Uffizi and of which BHC2701 is a copy, is more dynamic in pose, and probably shows him standing, compared to this later seated ‘Pandofini’ one. For the most modern Italian commentary see Federico Tognoni in 'Iconografia Galileiana' (Le Opere di Galileo Galilei': Appendice, vol 1, Florence, 2013) in which it is item D22, pp.70-71, as by 'Justus Suttermans(?)'.

The 12 inch gold-plated copper discs contain greetings in 60 languages, samples of music from different cultures and eras, and natural and man-made sounds from Earth. They also contain electronic information that an advanced technological civilization could convert into diagrams and photographs. The cover of each gold plated aluminum jacket, designed to protect the record from micrometeorite bombardment, also serves a double purpose in providing the finder a key to playing the record. The explanatory diagram appears on both the inner and outer surfaces of the cover, as the outer diagram will be eroded in time.

This artist's concept of NASA's Mars Reconnaissance Orbiter features the spacecraft's main bus facing down, toward the red planet. The large silver circular feature above the spacecraft bus is the high-gain antenna, the spacecraft's main means of communicating with Earth. The long, thin pole behind the bus is the antenna for the Shallow Subsurface Radar instrument (SHARAD). Seeking liquid or frozen water, this instrument will probe the subsurface using radar waves at frequencies of 15 to 25 megahertz, "seeing" in the first few hundred feet (up to 1 kilometer) of Mars' crust. The large instrument covered in black thermal blanketing in the center is the High Resolution Imaging Science Experiment camera (HiRISE). It will provide the highest-resolution images ever taken from Mars orbit. The Electra telecommunications package is the gold-colored instrument directly left of the high-resolution camera. It will act as a communications relay and navigation aid for Mars spacecraft. To the right of the high-resolution camera is the Context Imager (CTX).

Original caption: "A portion of the far side of the Moon looms large just beyond the Orion spacecraft in this image taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays. The spacecraft entered the lunar sphere of influence Sunday, Nov. 20, making the Moon, instead of Earth, the main gravitational force acting on the spacecraft. On Monday, Nov. 21, it came within 80 miles of the lunar surface, the closest approach of the uncrewed Artemis I mission, before moving into a distant retrograde orbit around the Moon."
