... 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. ...

... Comet Ikeya-Zhang, designated C/2002 C1 (Ikeya-Zhang), is named after Kaoru Ikeya of Shizuoka prefecture, Japan, and Daqing Zhang of Henan province, China, who independently discovered it on the night of 1 February 2002.

... Although they all formed from similar material, it is a mystery why the planets closest to the Sun Mercury, Venus and Earth are so different.

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. ...
