... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...

... SPACE.com) -- Streams of glittering stellar gems on the outer edges of Andromeda are remnants of an ancient galactic collision that helped shape the spiral galaxy. Astronomers using the DEIMOS spectrograph on the Keck II Telescope in Hawaii determined this by surveying Andromeda, our galaxy's nearest large galactic neighbor, and discovered a trail of stars which they believe were part of a different galaxy that merged with Andromeda some 700 million years ago. ...

Next: The Echelle Relation Up: Wavelength Calibration Previous: Wavelength Calibration . A preliminary step to the wavelength calibration consists of extracting the orders of the WLC image which can then be used to determine the dispersion relation in two steps: . ... Both methods are based on the echelle relation and therefore are not applicable if the disperser is not an echelle grating, as it is the case for EFOSC which involves a grism disperser. ...
