- JAN H. OORT DIES AT 92; CHARTED SOLAR SYSTEM'S PLACE IN THE MILKY WAY
-
- By John Noble Wilford - New York Times News Service
-
- Jan H. Oort, the Dutch astronomer who made major discoveries about the
- dynamics of the Milky Way galaxy, the mass of the cosmos, and the
- origin of comets, died last Thursday in Leiden, the Netherlands. He
- was 92 and lived in Leiden.
-
- He died of complications from a broken hip, Dr. Tyeerd Van Albada, an
- astronomer at the University of Groningen in the Netherlands, said
- yesterday. "He was the father of Dutch astronomy," Van Albada said of
- Oort.
-
- As an astronomy professor at the University of Leiden and for years
- director of its observatory, Oort established a reputation as one of
- the century's foremost explorers of the universe. One of his earliest
- and most important achievements was to establish the rotation of the
- Milky Way and to chart the solar system's place in that galaxy.
-
- Soon after he joined the Leiden faculty in 1926, Oort obtained the
- first direct evidence of the Milky Way's rotation. Through complex
- calculations, he measured the relative velocities of star moving with
- the rotating galaxy and deduced their distances from the galactic
- center. In this way, he determined that the sun and its planets were
- not even close to the galaxy's center but 30,000 light-years away, in
- the galactic hinterland.
-
- "Like a modern Copernicus, Oort showed that our position in nature's
- grand scheme was not so special," said Dr. Seth Shostak, an astronomer
- at the SETI institute in Mountain View, Calif., who worked for many
- years at the University of Groningen.
-
- Oort was elected to lead several international astronomical groups,
- was awarded the Vetlesen Prize by Columbia University and received
- many honorary degrees, including ones from Oxford, Cambridge, and
- Harvard universities.
-
- Oort is survived by his wife, two sons and several grandchildren and
- great-grandchildren.
