Name: Albert Francis Arthur Lofley Jones Birthdate: 9 Aug 1920 Birthplace: Christchurch, New Zealand Today is the anniversary of the birth of amateur astronomer Albert Francis Arthur Lofley Jones. His achievements include the discovery (on 6 Aug 1946 while observing the variable star U Puppis) of comet C/1946 P1 (Jones) and the co-discovery on 18 Nov 2000 (with astronomer Syogo Utsunomiya of Kumamoto, Japan) of the long-period comet C/2000 W1 (Utsunomiya-Jones) (pictured here on 18 Jan 2001). He was also the co-discoverer of supernova SN 1987A (seen here as the bright star to right of centre of image) in the Large Magellanic Cloud. However, Albert Francis Arthur Lofley Jones is perhaps best remembered for his remarkable skills as a variable star observer. He was also the co-discoverer of supernova SN 1987A (seen here as the bright star to right of centre of image) in the Large Magellanic Cloud. However, Albert Francis Arthur Lofley Jones is perhap...
Name: Laurent Cassegrain Birth: around 1629 Birthplace: Chartres,France Today is the anniversary of the Birth of the French Catholic priest and instrument maker Laurent Cassegrain. Although this image may be a likeness of Laurent Cassegrain, no verifiable portrait of him is known to exist. he is best known to astronomers as being the probable inventor of a type of reflecting telescope which uses a combination of a primary concave mirror and a secondary convex mirror . Now known as the Cassegrain reflector, Cassegrain’s design first appeared in the 25 Apr 1672 issue (pictured) of Le Journal des Sçavans (established by French writer Denis de Sallo in 1665 and the earliest academic journal published in Europe). The 55 km diameter lunar crater Cassegrain, located to the south east of the larger crater Lebedev on the far side of the Moon and seen here immediately to the lower right of image centre, is named in his honour.
Name: Christoph Scheiner Birth: 25 Jul 1573 place: in Wald,Mindelheim,Germany Today is the anniversary of the birth of the German Jesuit scholar, astronomer and mathematician Christoph Scheiner. One of the first to use the newly-invented telescope for astronomical observations Scheiner is probably best remembered for the co-discovery of sunspots in 1611 and for being one of the first astronomers to carry out systematic observation of sunspot activity. The 110 km diameter lunar crater Scheiner, located in the densely cratered region west of the walled plain Clavius, is named in his honour.
