What kind of orbit does comets have?
Comets typically have elliptical orbits, meaning they follow a path that is elongated and can bring them close to the sun at one point in their orbit and then far away at another point. This results in significant changes in their speed and distance from the sun during their journey.
What is a scientific context for comet?
In a scientific context, comets are icy celestial bodies that originate from the outer regions of the solar system, such as the Kuiper Belt and the Oort Cloud. Comets are composed of a mixture of water ice, frozen gases, dust, and rocky materials, and they become prominently visible when they approach the Sun, causing the ice to vaporize and form a glowing coma and tail. Studying comets provides insights into the early solar system's conditions and the building blocks of planets, as they are considered to be remnants from its formation over 4.6 billion years ago. Additionally, comets may carry organic compounds and water, which are of interest in the search for the origins of life on Earth and beyond.
What is Comet hunting?
= Comet Hunting = by William A. BradfieldSome new comets have been discovered accidently by amateur astronomers whilst making variable star or deep sky observations. Surprisingly a few bright comets displaying tails have been discovered with the naked eye by observant members of the general public (including for example farmers and in-flight airline pilots). However, the vast majority of visually discovered comets are found by comet hunters carrying out systematic telescope searches of selected areas of the night sky. As the motion of all comets is directed around the Sun and because these bodies brighten as they move towards the Sun, there is a greater potential for the visual discovery of a new comet in the skies towards the Sun rather than away from the Sun's direction. This means that searches should be concentrated on the western sky after evening twilight and on the eastern sky before morning twilight. From the astronomical viewpoint there is no particular time during the year which favours the discovery of new comets. A search can be undertaken at any time providing there is no bright Moon above the horizon. Searches of the prime sky areas should be made twice a month, the first being early in the Moon free period and the second towards the end of that period. The first search is often rewarding because it could reveal a comet which could have been brightening substantially in a sky covered by bright moonlight. Furthermore, the first search could show a comet which has moved out from the Sun's direction. Some comets may normally never brighten sufficiently to be detected in small telescopes even when they are inside the Earth's orbit. However, if they undergo an outburst of brightness they could become easily seen. Thus, the twice-a-month search provides an increased chance to discover these outburst comets. Studies undertaken by various investigators on the discovery circumstances of previously discovered comets show that more comets have been discovered in the morning sky than in the evening sky. Thus the prospective comet hunter should ensure that morning activity receives as much as if not more attention than evening effort. In recent times, the application of advanced CCD technology to discover very faint near Earth orbit objects will in the future severely limit the opportunities for new comets to be found visually with small telescopes. A prime example of the new technique is the very successful LINEAR program operating in New Mexico, described in the magazine "Astronomy" April 1999, pages 60 to 61. However, until a similar system is based in the southern hemisphere there will continue to be opportunities for the visual discovery of new comets which come from the south. William Bradfield is one of the most prolific comet hunters of the 20th Century, having been credited with the discovery of 17 comets visually between 1972 and 1995. William still actively seeks comets today, having recently discovered his 18th comet in April 2004
Which wavelength range in the electromagnetic spectrum has been the most fruitful in the search for organic molecules in space?
The radio wavelength range has been the most fruitful in the search for organic molecules in space. Radio telescopes have detected complex organic molecules in regions such as star-forming regions, comets, and interstellar clouds, providing valuable insights into the presence and chemistry of organic molecules in space.
How long had astronomers been searching for Pluto?
Astronomers had been searching for Pluto since the early 20th century, particularly after the discovery of Neptune in 1846, which led to speculation about an additional planet due to irregularities in Uranus's orbit. The search intensified in the 1920s, culminating in the discovery of Pluto by Clyde Tombaugh on February 18, 1930, after extensive observations and calculations. Thus, the search spanned several decades, driven by the quest to find the elusive ninth planet of our solar system.
Did Little Milton record went running to the end of the rainbow?
I believe little Milton did make a version of it. Ive been looking for that version too but for some reason it seems elusive, even when you search under his songs.

The Great Gatsby was written for what reason?
The Great Gatsby was written by F. Scott Fitzgerald to critique the American Dream and the pursuit of wealth and social status in 1920s America. It also explores themes of love, class, and the corruption of the American Dream.
