Jan Oort Cloud

Jan Hendrik Oort ForMemRS (/ˈɔːrt/ or /ˈʊərt/; 28 April 1900 – 5 November 1992) was a Dutch astronomer who made significant contributions to the understanding of the Milky Way and who was a pioneer in the field of radio astronomy. His New York Times obituary called him “one of the century’s foremost explorers of the universe”; the European Space Agency website describes him as “one of the greatest astronomers of the 20th century” and states that he “revolutionised astronomy through his ground-breaking discoveries. ” In 1955, Oort’s name appeared in Life magazine’s list of the 100 most famous living people. He has been described as “putting the Netherlands in the forefront of postwar astronomy. ”



Moon Boots are convenient in that they cater for both genders and all ages. Adults, adolescents and teenagers can look warm and trendy while newborns and kids can look cosy and cute. They are extremely versatile in this regard. Going to the moon again is causing far more controversy today than it could have back in the sixties. Some Americans doubt we can afford it and others are not sure they have seen the "giant leap for mankind" that the first moon shot promised. It depends on who you ask but don't dare ask me. I didn't think the first moon landing had much significance for reasons that few people share with me. Life as we know it depends on the presence of three ingredients: liquid water; a source of energy for metabolism; and the right chemical ingredients, mainly carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. With this new discovery of the existence of hydrogen, in the tattle-tale plume shooting out from the surface of Enceladus, Cassini has revealed to the prying eyes of curious astronomers, that this small, icy moon has almost all of these ingredients important for habitability. At this point, Cassini has not detected the presence of phosphorus and sulfur in the hidden subsurface ocean of this distant small world, but many planetary scientists suspect that they will eventually be detected because the rocky core of Enceladus is believed to be similar to certain meteorities that contain these two critical elements.
