Latest Comets Stories
Comet 67P/Churyumov–Gerasimenko has five basic but diverse categories of terrain type, as well as 19 distinct geomorphological boundaries, according to early data obtained by the ESA’s Rosetta mission and published in a special edition of the journal Science.
A special issue of the journal Science, to be published Jan. 23, 2015, reveals details about the shape, evolution and lifespan of comet 67P-Churyumov/Gerasimenko.
The closest planet to the sun appears to get hit by a periodic meteor shower, possibly associated with a comet that produces multiple events annually on Earth.
Terrestrial water most likely did not come from comets like 67P/Churyumov-Gerasimenko, meaning that the H2O found on Earth was most likely brought here by asteroids.
The release of the first color image of Comet 67P/Churyumov-Gerasimenko, the comet upon which the ESA’s Philae probe landed last month, suggests that it may not be steel gray or charcoal black as previously believed.
A set of instruments on the European Space Agency's Rosetta spacecraft has picked up a mysterious "song" from Comet 67P/Churyumov-Gerasimenko. The sounds are thought to be oscillations in the magnetic field around the comet.
If recent chemical signatures detected from 67P/Churyumov–Gerasimenko are any indication, then it’s a good thing the forthcoming attempt to land a probe on the surface of the comet is an unmanned mission, because the astronauts might not be able to handle the odor.
A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved.
After a journey of more than six billion kilometers through the Solar System, the ESA’s Rosetta probe is closing in on comet 67P/Churyumov–Gerasimenko.
Amateur astronomers anxiously await the mid-August Perseid meteor shower every year. Typically occurring on 11th, 12th and 13th of August, the meteor shower is one of the treats of the summertime sky.
Jean Elias Benjamin Valz was born on May 27, 1787 in Nimes in France. He was formally trained as an engineer, but he became intrigued with astronomy, specifically comets, after witnessing the return of the Comet Encke. Before leaving his home to become the Director of the Marseille Observatory, he built a private observatory in it. He theorized that abnormalities in the orbit of Halley's Comet could be explained by a planet beyond Uranus. Scientist would later discover this planet and...
Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
Halley's Comet -- Comet Halley, more generally known as Halley's Comet after Edmond Halley, is the best-known and the brightest of the "short-period" comets from the Kuiper belt that visit the inner solar system in years or decades-long orbits rather than the millennia of comets from the Oort Cloud. Early History Having perceived that the elements of the comet of 1682 were nearly the same as those of two comets which had appeared respectively in 1531 and 1607, Halley concluded that...
Comet Encke -- Because of its proximity to the Sun and its stable orbit, comet Encke is probably one of the most evolved comets that still remains active. It may represent a transition object between an active comet and the defunct comets that are thought to make up a significant percentage of the near-Earth asteroid population. The orbit of comet Encke is very stable both in its size and orientation because it can pass no closer to Jupiter than about 0.9 AU. This orbital stability...
