The Doppler shift is the effect of sound increasing or decreasing in pitch as an object moves towards or away from you. ... Light works the same way, except light is shifted to redder colours when an object is moving away, and to blue colours when an object is travelling towards us. ... Almost every object he observed had its light stretched to redder colours, indicating essentially everything in the Universe was moving away from us. ... So the Hubble constant tells us how old the Universe is. ...

... 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. ...
