SpletComet tails can stream out up to 100 million km in length! However, the density of material in the tail is not very large. So while you have to prepare your spacecraft to be hit by fast … SpletGrains of size 1–100 μm are ejected at a speed of several hundred meters per second and under the action of solar radiation pressure they form the comet tail which disperses …
SpletThe Comet assay has gained increasing popularity for use in human biomonitoring or epidemiologic studies; however, one of the shortcomings of the Comet assay is a lack of agreement on a single appropriate Comet parameter that is capable of adequately describing observed DNA damages.

SpletAs a comet gets closer to the sun, the ices on the surface of its nucleus vaporize and form a cloud called a coma around the nucleus that can expand out to 50,000 miles (80,000 km). … While the solid nucleus of comets is generally less than 30 km across, the coma may be larger than the Sun, and ion tails have been observed to extend 3.8 astronomical units (570 Gm; 350×10 mi). The Ulysses spacecraft made an unexpected pass through the tail of the comet C/2006 P1 (Comet McNaught), on … Prikaži več A comet tail—and coma—are features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the … Prikaži več The observation of antitails contributed significantly to the discovery of solar wind. The ion tail is the result of ultraviolet radiation ejecting electrons off particles in the coma. Once the particles have been ionised, they form a plasma which in turn induces a Prikaži več Mercury and Venus possess similar tails caused by interaction of the solar wind with their atmospheres. On January 29, 2013, Prikaži več In the outer Solar System, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. … Prikaži več If the ion tail loading is sufficient, then the magnetic field lines are squeezed together to the point where, at some distance along the ion tail, magnetic reconnection occurs. This leads to a "tail disconnection event". This has been observed on a number of occasions, notable … Prikaži več • Comets at Curlie • Comets page at NASA's Solar System Exploration • International Comet Quarterly at Harvard.edu Prikaži več
