Lawrence Hugh Aller: The Twinkle Behind the Stars

-


Hello, friends of all ages! Today, let's embark on an amazing journey through the universe as we explore the life and works of a very special scientist, Lawrence Hugh Aller. You may be wondering, "Who is Lawrence Aller?" Well, buckle up! By the end of our journey, you'll know all about this brilliant star-gazer and his significant contributions to the world of astronomy.

1. Who Was Lawrence Hugh Aller?
Lawrence Hugh Aller was a star - not the kind you see on television, but the kind that studies the stars in the sky! He was an astronomer, which means he spent his life trying to understand the secrets of the universe. Born on September 24, 1913, in Tacoma, Washington, USA, he was passionate about the stars and the sky from a very early age.

2. Educational Journey:
Lawrence's journey towards becoming a star-gazer started with his education. He attended the University of California, Berkeley, where he earned his bachelor's degree in 1936 and his Ph.D. in 1943. These degrees were like his 'training missions' before he launched into his career as an astronomer.

3. Stellar Career:
After completing his education, Lawrence joined the University of Michigan in 1945 as an instructor, where he began his real journey among the stars. He moved to UCLA (University of California, Los Angeles) in 1948, where he spent the rest of his career, eventually becoming a full professor.

4. Major Contributions:
Lawrence made many exciting discoveries throughout his career. Here are some of the most important ones:

  • Nebulae: Lawrence was famous for his work on nebulae - these are big, colorful clouds of gas and dust in space. He used special tools to study the light coming from these nebulae, which helped us understand what they're made of and how they behave.
  •  Abundance of Elements in Stars: Lawrence also studied how much of each element (like hydrogen, helium, and others) there are in stars. This is like figuring out the ingredients in a star-recipe!
  •  Stellar Atmospheres: He made significant contributions to understanding stellar atmospheres - that's like the 'skin' of a star!

 

5. Books:Lawrence was not only a great scientist but also a fantastic writer. He shared his knowledge and love for the stars through several books:

  •  "Atoms, Stars, and Nebulae" (1956):** This book is like a cookbook for stars! It explains how stars and nebulae are made from atoms.
  •  "Nebulae and Galaxies" (1961):** In this book, Lawrence took his readers on a tour of nebulae and galaxies - like a space travel guide!
  • "The Galaxy" (1971):This book is all about our home in space - the Milky Way galaxy.
  •  "Astrophysics: The Atmospheres of the Sun and Stars" (1963):** This book explains the atmospheres of the sun and stars, much like learning about the skin of these celestial bodies.


6. Honors and Awards:
Lawrence's work was so amazing that he received many awards. He was awarded the Henry Norris Russell Lectureship by the American Astronomical Society in 1976. This is one of the highest honors an astronomer can receive!

7. A Lasting Legacy:
Lawrence passed away on March 16, 2003, but his legacy still shines bright. His dedication to observation, theory, education, decency, and kindness has left a lasting mark on the world of astronomy. His journey started from humble beginnings, and with determination and a love for learning, he became one of the world's finest astronomers


His diverse research projects included stellar spectroscopy, solar research, nebular theory, nebular observations, and even the Mie scattering theory to explain the zodiacal light! He was engaged in an impressive array of simultaneous research projects that kept him busy and productive

Discover of comet C/1946 P1 : Albert Francis Arthur Lofley Jones

 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.

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.

Sir Isaac Newton:History of Astronomy

  Today is the anniversary of the birth, at Woolsthorpe, near Grantham, Lincolnshire on 25 Dec 1642, of the English physicist, mathematician and astronomer Sir Isaac Newton .     Although his achievements were many, he is probably best remembered for his ‘Philosophiæ Naturalis Principia Mathematica’ (Mathematical Principles of Natural Philosophy). Often referred to as ‘The Principia’ and widely considered as being one of the most important works in the history of science, its contents i ncluded details of Newton's laws of motion (which went on to form the basis of classical mechanics) together with his famous law of universal gravitation. The 79 km diameter lunar crater Newton, located in the south polar region close to the southern limb of the Moon, and seen here with the satellite crater Newton D overlying its north-northeastern rim, is named in his honour.  Credit: societyforthehistoryofastronomy.com
