Comet Hale-Bopp

Comet Hale-Bopp (formally designated C/1995 O1) was probably the most widely observed comet of the 20th century, and one of the brightest seen for many decades. It was visible to the naked eye for a record 18 months, twice as long as the previous record holder, the Great Comet of 1811. Hale-Bopp was discovered on 23 July 1995 at a very large distance from the Sun, raising expectations that the comet could become very bright when it passed close to the Sun. Although comet brightnesses are very difficult to predi ...

Comet Hale-Bopp was observed intensively by astronomers during its perihelion passage, and several important advances in cometary science resulted from these observations. Comet Hale-Bopp - Sodium tail. One of the most remarkable discoveries was that the comet had a third type of tail. In addition to the well-known gas and dust tails, Hale-Bopp also exhibited a faint sodium tail, only visible with powerful instruments with dedicated filters. Sodium emission had been previously observed in other comets, but ...

In the early 90's, Dr. Brown was instructed in Remote Viewing (RV), a psychic technique originally developed for the CIA through Stanford Research Institute. According to proponents, Remote Viewing can be used to access information from any geographic or temporal location; however, it is generally considered a pseudoscience by mainstream scientists. After his training, Dr. Brown then developed a methodology he calls Scientific Remote Viewing (SRV). In 1995, he founded the Farsight Institute, a non-profit organization whose purpose is to conduct and disseminate research of the remote ...

In ancient times, only the Sun and Moon, a few hundred stars and the most easily visible planets had names. Over the last few hundred years, the number of identified astronomical objects has risen from hundreds to over a billion, and more are discovered every year. Astronomers need to be able to assign systematic designations to unambiguously identify all of these objects, and at the same time give names to the mo ...

Atland, or Aldland as it is sometimes spelt, is the name applied to Atlantis by the Oera Linda Book. Said to have been destroyed in a conflagration of nature in 2194 BCE, it was allegedly located in what is now the North Sea. All dates in the Oera Linda Book are reckoned from this event. Note: some early researchers gave the year as 2193 BCE, but this is based on an erroneous calculation that assumes the existence of a 'Year Zero' between ...

Comet Hyakutake (pronounced /ħʝakutake/ or /ħʃakutake/; formally designated C/1996 B2) was a comet that was discovered in January 1996, passed very close to the Earth in March of that year, and was dubbed The Great Comet of 1996. It was one of the closest cometary approaches to the Earth in the last 200 years, which resulted in the comet becoming very bright, and it was seen by a large number of people around the world. The comet temporarily upstaged the long-awaited Comet Hale-Bopp which was approaching the inner solar system at the time, althou ...

A comet (denoted by ☄) is a small body in the solar system that orbits the sun and (at least occasionally) exhibits a coma (or atmosphere) and/or a tail — both due primarily to the effects of solar radiation upon the comet's nucleus, which itself is a minor planet composed of rock, dust, and ices. Due to their origins in the outer solar system and their propensity to be highly affected by relatively close approaches to the major planets, comets' orbits are constantly evolving. Some are moved into sungrazing orbits that destroy the comets when they near the sun, while others ...

Comet - Early observations and thought. Historically, comets were thought to be unlucky, or even interpreted as attacks by heavenly beings against terrestrial inhabitants. Some authorities interpret references to "falling stars" in Gilgamesh, Revelation and the Book of Enoch as references to comets, or possibly bolides. In the first book of his Meteorology, Aristotle propounded the view of comets that would hold sway in Western thought for nearly two thousand years. He rejected the ideas of several ...

The vast majority of comets are never bright enough to be seen by the naked eye. They generally pass through the inner solar system unseen by anyone except astronomers. However, occasionally, a comet may brighten to naked eye visibility, and even more rarely it may become as bright or brighter than the brightest stars. How bright a comet becomes depends on three main factors. Great comet - Size and activity of the nucleus. Cometary nuclei vary in size from a few hundreds of metres across or less to many ki ...

The brightest members of the Kreutz Sungrazers have been spectacular objects, easily visible in the daytime sky. The three most impressive have been the Great Comet of 1843, the Great Comet of 1882 and Comet Ikeya-Seki. Another very notable Kreutz Sungrazer was the Eclipse Comet of 1882. Kreutz Sungrazers - The Great Comet of 1843. The Great Comet of 1843 was first noticed in early February of that year, just over three weeks before its perihelion passage. By February 27 it was easily visible in the daytim ...

The most famous sungrazers are the Kreutz Sungrazers, which all originate from one giant comet which broke up into many smaller comets during its first passage through the inner solar system. An extremely bright comet seen by Aristotle and Ephorus in 371 BC is a possible candidate for this parent comet. The Great Comets of 1843 and 1882, and Comet Ikeya-Seki in 1965 were all fragments of the original comet. Each of these three was briefly bright enough to be visible in the da ...

According to the IAU, apart from a limited number of bright stars with historic names, stars do not have proper names. Where historic names exist, these names are, with a few exceptions, taken from the Arabic language: this reflects the leading role of Arab culture in astronomy while Europe was experiencing the Middle Ages. See List of traditional star names for a list of some of these names. There are no more than a few thousand stars that appear sufficiently bright in the Earth's sky to be visible to the naked eye, so this represent ...

The comet was discovered on January 30, 1996 by Yuji Hyakutake, an amateur astronomer from southern Japan. He had been searching for comets for some years, and had moved to Kagoshima partly for the dark skies in the nearby rural areas. He was using a powerful set of binoculars with six-inch objective lenses to scan the skies on the night of the discovery. The comet he found was actually the second Comet Hyakutake, the first being comet C/1995 Y1, which Hyakutake had discovered just a few weeks earlier. While he was re-observing h ...

A study by Brian Marsden in 1967 was the first attempt to trace back the orbital history of the group to identify the progenitor comet. All known members of the group up until 1965 had almost identical orbital inclinations at about 144°, as well as very similar values for the longitude of perihelion at 280–282°, with a couple of outlying points probably due to uncertain orbital calculations. A greater range of values existe ...
