"Festival Fireworks-like gorgeous sight" Comet "sparkling" … "shelling" Comet that may occur after the wonderful scene attracts global enthusiasts. When observing? what are the tools? observing? CAs Purple Mountain Observatory Wang thought a researcher for a public offer advice.
Wang thought introduction, it is expected that the artillery shelling the comet will occur at Beijing time 4 July 13: 52 am, shelled 6 months after half an hour the comet will begin to enter our night vision. This is beneficial to the public on shelling out a lot after Jet "Storm" and the observation of the gas clouds of dust. But the bombardment of observation before it is also important. From 26 January, Moonlight effect has waned, the comets observation.
26 June – 9 July, a temple, comets will appear after dark sky, is located in the South and the Jupiter constellation corner Markab nearby. Each night the best observation time from days to just start black to black after two hours. The brightness of a comet impact before about 11, Star, strike the brightness may increase after light up dozens of times, becomes a star 7, etc. Observations of Comet before shelling, preferably with a diameter of 30 cm above the high-quality telescope. If you want to observe shelling were raging everywhere "after", with 10 cm of Comet more aperture telescope it is possible to observe this Comet. But to take this historic event of the lens, CCD with flexible (electronic detector) is also available on digital cameras, etc.
Observation in addition to the requirements of the clear night sky and without blocking the obstacles, but also to avoid the urban lights and the influence of the moon. Observations should be prepared before a suitable star, star's magnitude is best able to 10 and other stars, and familiar with the star map looking for the comet. In the telescope, the Comet and the star shape is different, stars, star-shaped Comet is a little Dim fog. Astronomers in early June on the comet's observation that it seems like a fog of Western pumpkin shape shaped, Comet tail back into the Sun, and enthusiasts in the observation of half an hour later, will see the Comet is relative to the sky background, this is the difference between moving Comet and river-Nebula.
Wang thought reminder, to obtain good observations need to practice, first with locatingan alignment and to find out after the comet's field of view, with a guide star mirror or primary mirror of patience to find the comet.
"Bombard" Comet
12 January 2005, the depth value 3.3 million "hits", the spacecraft was successfully launched in 4.31 billion kilometers of space flight, will be held on 3 July launch a strike. If successful, the 370 kg of giant "ammunition" will be held on 4 July to 10.2 km of Cosmic Velocity fieriness Temple, Comet Comet nucleus, its power is equal to 4.5 tons of TNT high explosive power of the explosion, the possibility of Comet nuclei knocked out a surface of 20 meters deep, the football field that large circular big pit. This brass tank in a moment of impact is high temperature melting and evaporation will produce Festival Fireworks-like gorgeous spectacle, and the impact of large numbers of comets sputtered dust and gases will make the Temple a, Comet sparkling, earth it possible through a small telescope saw this unprecedented Singularity sky. This is the first time in human history of the artificial sky "bombard" Comet space experiment.
"Bombard" Comet 4 possible after
Chinese Purple Mountain Observatory Wang thought introduction, Temple, a researcher at a number of comets Center is a diameter of about 6 km of Comet nuclei, Comet nucleus consists of large amounts of water ice and carbon dioxide ice, methane ice substance and material composition of rock dust. July 4, depth impact there will be various possibilities after.
The first possibility is missed Comet nucleus, the reason for this is that the impact is considerable difficulty, because the spaceship "ammunition" and comets are moving quickly to cosmic velocity, and sport routes and not on the same line, it can be compared to ride horses at dizzying speed, would like to use arrow flying eagle, it is very difficult;
The second possibility is although hit Comet nuclei, but since Comet nucleus hard than expected, the type of impact craters and not substance, sputtering out less, Comet zengliang not obvious;
A third possibility is impinging upon explosion pits of no less than 30 metres deep, a football field. Impact is high temperature melts instantly vaporized material produces the Festival Fireworks-like gorgeous spectacle, a large number of the sputtering out dust gas substances so that the Temple a, Comet sparkling and continuous days and even weeks long.
A fourth possibility is that Comet Comet nucleus rather loosely, in intense shelling of disintegration, turned into a few major nuclear, or even all collapsed.
"Bombard" important hyesung
"Both from a scientific perspective, or from the public appreciation of perspective, 7 4 upcoming ' shelling ' Comet space experiments are of great significance. "Wang thought introduction, this incident was the 1994 collision between the" Comet wood "another astronomical hotspot event, the difference is that the last human on passively observing Jupiter was hit by the" heroic era ", this is humanity go defensive into offensive, take the initiative to Comet. This is the human initiative in full embodiment in the universe.
From a scientific perspective, impact, impact class will carry your camera to the Comet nucleus, take these wonderful photos until "martyred" before the 2 seconds. In the "before" their lives, it has images and data back to the spacecraft. The spacecraft itself also comes with a high-resolution camera and infrared spectrometer and precise observation device, a comet is the safe distance of 500 km-range shooting impingement cupola of the mushroom cloud, record the size of impact craters, depth, shape and internal structure, analysis from Comet nucleus injection material components inside and observed valuable images and data back to Earth.
As the Comet with the solar system's most original material, these images and data to help mankind first unveiled the Comet inner secrets, but also will help uncover the Earth and the origin of the solar system and the mystery of the universe and the origin of life. In addition, these data also to prevent comet impact Earth provides valuable information.
/P>From the public appreciation of perspective, this is the first time the beauty of his own invention, ornamental Theatre is very high. At present, the astronomical event has attracted a large number of amateur astronomers. The world of amateur astronomers have already begun to telescope the Temple a number of comets, the famous "Hubble Space Telescope", "", "Spitzer Space Telescope," Chandra, "space telescope is ready in this unprecedented astronomical events in a thirst.
