Gart Westerhout facts for kids
Gart Westerhout (born June 15, 1927 – died October 14, 2012) was a famous Dutch-American astronomer. Even before finishing college, he was already known around the world as a "radio astronomer" in the Netherlands. He studied things like radio waves coming from space and special signals from hydrogen gas in the space between stars. Later, he moved to the United States, became a citizen, and held many important jobs in science and at universities.

Gart Westerhout's Career
Gart Westerhout was born in The Hague, a city in the Netherlands. He studied at the University of Leiden with two very important astronomers, Hendrik van de Hulst and Jan Hendrik Oort. Many of his friends and colleagues in the Netherlands also became famous scientists.
Early Discoveries
Gart Westerhout earned his Ph.D. in Astronomy and Physics in 1958. He made several big discoveries. One was the "Westerhout Catalog." This catalog lists many radio sources in space, which are still called "W" numbers today, like Westerhout 49. He created this catalog using the new Dwingeloo telescope.
He also mapped out the neutral hydrogen gas in the outer parts of our Milky Way Galaxy. His work helped scientists see the first hints of spiral shapes in the gas. It also showed how our galaxy rotates differently in different places. He even helped create a new system for mapping locations in our galaxy, which is still used today.
Leading Astronomy Programs
While still at Leiden University, he worked as an assistant and then as a chief scientist. In 1962, he moved to the University of Maryland in the United States. He became the first director of their new astronomy program. He helped this program grow into a major department where students could earn advanced degrees.
At Maryland, he led a big project using a large radio telescope. This project helped us learn more about the structure of our galaxy. It also trained many students who went on to become successful astronomers themselves. He stayed at the University of Maryland until 1977. During that time, he also visited the Max-Planck-Institut in Germany.
From 1977 to 1993, Gart Westerhout was the Scientific Director at the U.S. Naval Observatory in Washington, DC. Here, he helped the observatory use new ways to collect astronomical data. This included using telescopes in Flagstaff and new techniques with radio and optical waves.
Family Life and Recognition
Gart Westerhout had five children with his wife, Judith: Magda Cathleen, Gart, Brigit, Julian, and Anthony. An asteroid was named 5105 Westerhout in his honor by the astronomer who discovered it, Edward L. G. Bowell.
Memberships and Awards
Gart Westerhout was a member of many important scientific groups. These included the International Astronomical Union (IAU) and the American Astronomical Society (AAS). He shared his knowledge with many organizations, like the National Science Foundation (NSF).
He also received several awards and special recognitions. These included a NATO Fellowship, a Humboldt Prize, and being listed in "Outstanding Educators of America."
