http://hubblesite.org/newscenter/archive/releases/2002/24/image/a/ A composite image of the Crab Nebula showing the X-ray (blue), and optical (red) images superimposed. The size of the X-ray image is smaller because the higher energy X-ray emitting electrons radiate away their energy more quickly than the lower energy optically emitting electrons as they move.

... Submitted by Al Takeda on 11/06/2013 09:00:23 . Nova Delphinus 2013 (Nova Del 2013) - Dimming . This classical nova is getting dimmer. ... Notice that the star has turned to a reddish color. The energy from the nova is being absorbed by the surrounding material and is being re-emitted in the Hydrogen-alpha wavelength. This energy is also being spread out over a larger area and it is causing a temperature drop. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...
