En esa zona, el astronomo holandes Jan Oort
piensa que flotan unas cien mil millones de enormes bolas congeladas de polvo, las cuales fueron creadas al mismo tiempo que el Sol y los planetas.
has been for several decadesthe dean of the distinguished modern school of Dutch astronomers.
Astronomer Jan Oort
realized the potential of radio waves in the early 1940s.
This hypothetical region was named the Oort cloud after mid-20th century Dutch astronomer Jan Oort
, who first proposed such a twilight region to explain what seemed to be a hidden reservoir of comets.
The larger of these two storehouses, proposed by Dutch astronomer Jan Oort
, takes the form of a huge spherical cloud residing on the far fringes of the solar system.
Dutch astronomer Jan Oort
(1900-1992) inferred its existence in 1950, based on the observation that the orbits of long-period comets (those with periods greater than 200 years) are large and randomly oriented in the sky.
That same year, Dutch scientist Jan Oort
postulated a spherical cloud of comets orbiting about 100,000 AU from the sun.
Under the leadership of Jan Oort
, Dutch astronomers were at the forefront of probing and mapping our galaxy with the first generation of radio telescopes.
