... Pluto's orbit is also highly inclined -- tilted 17 degrees to the orbital plane of the other planets. ... Ground-based observations indicate that Pluto's surface is covered with methane ice and that there is a thin atmosphere that might freeze and fall to the surface as the planet moves away from the Sun. ... This is the first image-based surface map of the solar system's most remote planet, Pluto. ... This is the first surface map of Charon, the moon of the solar system's most remote planet, Pluto....

... When the Voyager 2 spacecraft flew by the planet Uranus in January 1986, astronomers were treated to their first close-up glimpse of the satellites that orbit the seventh planet. ... But by far the most intriguing of those 15 satellites was a jigsaw-puzzle world called Miranda . ... How dark was it at Miranda? One of the Voyager scientists put it this way: Taking pictures in the Uranus system is like trying to do photography in a ballpark at night when the only light comes from a single candle. ...

Serguei NATANZON (UIM, Moscow): Klein topological field theories . It is well-known that classical two-dimensional topological field theories are in one-to-one correspondence with commutative Frobenius algebras. An important extension of classical two-dimensional topological field theories is provided by open-closed two-dimensional topological field theories. In this paper we extend open-closed two-dimensional topological field theories to nonorientable surfaces. ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

... RSS CHANNELS: ASTRONOMY February 23, 2006 Two New Moons--and Maybe Some Rings--for Pluto Adding to the growing compendium of Kuiper belt objects, astronomers have spotted two new moons orbiting Pluto. Observations with the Hubble Space Telescope from May of last year show two tiny dots revolving around the same center of gravity as the ninth planet and its largest moon, Charon. ... The moons may also be a source for dust that coalesces into rings around Pluto before dispersing. ... Or even rings. ...

... The most spectacular view however is from space, where large areas of aurora can be observed simultaneously, even the entire polar cap. ... Such pictures often show a continuous ring of aurora around the polar cap (picture above), caused mostly by electrons leaking out along magnetic field lines, from the plasma sheet of the Earth's magnetic tail. ... Field lines from the auroral oval are believed to lead to the plasma sheet. ... A near-Earth circular polar orbit has many uses. ...
