The outer solar system: Something new under the sun 2014-03-27T15:58:21Z At about the same time, Kuiper's countryman Jan Oort hypothesized that those widely scattered objects would have formed a spherical cloud of proto-comets orbiting as much as a light-year away from the sun. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z In 2003, Trujillo and several other scientists found the first object in this part of the solar system, known as the inner Oort cloud. Planet-like object nicknamed Biden could help explain solar system’s origins 2014-03-27T00:05:00Z Comet Siding Spring is especially interesting because of its formation in the Oort cloud during the early days of the solar system, making it a “long period” comet with an orbit of millions of years. Celestial Traveler, Closing on Mars 2014-08-04T04:00:00Z Lead researcher Chad Trujillo favors the idea that a sibling star forming in the same stellar nursery as the sun gravitationally elbowed some Oort Cloud residents inward as it flew by.

The outer solar system: Something new under the sun 2014-03-27T15:58:21Z Some would have ended up in the Oort cloud. Kuiper Belt Missions Could Reveal the Solar System’s Origins 2014-10-15T04:00:00Z Another possibility is that a massive rogue planet passed through at some point, kicking objects from the Kuiper belt outwards into the inner Oort cloud. New Dwarf Planet Has Most Distant Trajectory Known 2014-03-26T21:00:00Z As described by NASA, Comet Siding Spring spent billions of years in the Oort cloud, named for the 20th-century Dutch astronomer Jan Oort, who first predicted its existence. Celestial Traveler, Closing on Mars 2014-08-04T04:00:00Z In theory, such comets originate in a vast comet reservoir known as the Oort Cloud, which forms a kind of spherical halo around the Solar System. The Hunt for Super Pluto Comes Up Empty—For Now 2014-03-10T15:24:59Z It hailed directly from the Oort cloud, the icy reservoir of comets beyond the orbit of Pluto. Astronomy: Death of a comet 2014-02-19T18:50:49.140Z Admittedly, there's an even farther frontier out in the Kuiper belt, not to mention the Oort cloud beyond, but ... Me and my flying saucer 2014-01-29T18:51:59.174Z Most scientists believe it was not a comet with a nucleus, but rather a collection of pebbles and dust — the rocky remains of the comet from the Oort cloud. No light show expected from Comet ISON 2013-12-06T16:41:45Z Detected comets from the Oort cloud are rare, probably only a handful per century, Green said. Comet ISON, if it survives trip around the sun, could bring spectacular sky show 2013-11-24T23:10:45Z The Oort Cloud is made of the solar system’s leftover ingredients. Comet from the Oort Cloud Careens toward the Sun 2013-11-04T12:45:00.417Z The probe remains short of the Oort cloud, a reservoir of comets that is still part of the Solar System. Seven days: 13–19 September 2013 2013-09-18T17:20:41.640Z Stone said the spacecraft will pass through the far side of the Oort cloud in about 30,000 years. After 36 years, Voyager 1 goes interstellar 2013-09-13T01:09:00Z Scientists believe the comet hails from the Oort Cloud, a cluster of icy rocks that circle the sun about 50,000 times farther away than Earth's orbit. 'Comet of the Century' already may have fizzled out 2013-07-30T00:35:17Z In the fall, Van Oort was scouting for an event prospect for her friend Kalisz. The Rail: Horse Rescue Success Story: Philotimo 2013-06-10T20:07:44Z The only two things that completely surround Earth that way are the outer reaches of the Solar System—where the Oort Cloud of comets lives—and the cosmos itself. Universe's Biggest Gamma Ray Burst 2013-05-09T07:40:00Z Not coincidently this is also the speculated outer edge of the Oort cloud – a vast structure consisting of trillions of icy chunks of detritus flung outwards while our planets formed some 4.5 billion years ago. Voyager's Exit To The Stars...In 17,000 Years 2013-04-08T16:15:28.010Z That’s because of the Oort cloud — a region of comets in orbit around the sun. After 36 years, Voyager 1 goes interstellar 2013-09-13T01:09:00Z Others fall inwards from a still mysterious region beyond all known major and minor planets – the Oort cloud. Will This Be The Comet Of The Century? 2013-02-06T17:15:00.737Z Van Oort and Kalisz shared the care and the boarding costs for Timo for the first five months of his recovery. The Rail: Horse Rescue Success Story: Philotimo 2013-06-10T20:07:44Z “We wanted to run Windows 8 Apps across multiple monitors but it wasn’t possible without spending hundreds of dollars for specialized hardware,” said Don Van Oort -CTO. RetroUI Pro 3 Brings The Efficiency And Simplicity Of Windows 7 To Windows 8 PCs 2013-02-05T21:03:01Z “I've met somebody else, while you were working on the Oort Cloud project.” Glass future 2012-10-24T17:21:17.170Z “We’ll get to the inner edge of the Oort cloud in about 300 years,” Stone said. After 36 years, Voyager 1 goes interstellar 2013-09-13T01:09:00Z Oort cloud objects are also intriguing because they may represent material stolen from our stellar siblings. Will This Be The Comet Of The Century? 2013-02-06T17:15:00.737Z I dove closer to the sun than even she did at perihelion, and flew as far away as the Oort cloud at aphelion. Celestial bodies 2012-06-27T17:51:08.497Z Drs. Oort, Hookyaas, and Xuenen, German Christian writers of great repute, in the Bible for Learners declare the passage to be “certainly spurious” and “inserted by a later and a Christian hand.” The Eliminator; or, Skeleton Keys to Sacerdotal Secrets 2012-03-27T02:00:23.077Z They start out in the Oort Cloud, a vast collection of perhaps trillions of small, icy chunks that hover at the very outer edges of the Solar System.

Celestial bodies 2012-06-27T17:51:08.497Z The Alert was directed to all planets, satellites, stations, outposts, and all ships in space from Mercury to deep within the Oort Cloud far beyond the Slingshot construction sites. The Universe — or Nothing Perhaps we might speak about an �Oort Cloud� in economics too: big misconceptions and misunderstandings flying about in professorial minds, occasionally hitting Earth to great disaster. Definition & Reality in the General Theory of Political Economy For a very plain and honest statement of this view in our own sacred books, see Oort, Hooykaas, and Kuenen, The Bible for Young People, English translation, chap. v, p. History of the Warfare of Science with Theology in Christendom Captain Van Oort was a man of his inches in length, but in breadth about one-third more, being thickened and spread by the years that do this to a body containing a Christian mind. Springhaven : a Tale of the Great War My favorite reading at this period was the "Bible for Learners," a book most thoughtfully edited by three of the foremost scholars of modern Europe—Hooykaas, Oort, and Kuenen. Autobiography of Andrew Dickson White — Volume 2 Explorers studied and charted the surfaces, depths and atmospheres of each of the Solar System's bodies, and scrutinized the dynamics and constituents of space matter out to the Kuiper Belt and Oort Cloud. The Universe — or Nothing Captain Van Oort had picked up some English, and his wife could use tongue and ears in French, while Scudamore afforded himself and them some little diversion by attempts in Dutch. Springhaven : a Tale of the Great War Captain Van Oort would have lent him 500 guilders with the greatest pleasure, but Scudamore would not take more than fifty, to support him until he could obtain a ship.
