... Observers looking at an object that is moving away from them see light that has a longer wavelength than it had when it was emitted (a redshift), while observers looking at an approaching source see light that is shifted to shorter wavelength (a blueshift). ... By measuring the amount of the shift to the red, we can determine that the bright galaxy is moving away at 3,000 km/sec, which is 1 percent of the speed of light, because its lines are shifted in wavelength by 1 percent to the red. ...

... Magnetic Storms . ... Cosmic Rays . ... Energetic Particles . ... Solar fast Particles . We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. ... Should we be concerned about solar energetic radiation? ...

... My mother had a 'star named for me' with the International Star Registry (henceforth ISR) as a gift for this Christmas. ... On the back of the chart, a sticker described the precise location and visual magnitude of the star, taken from the Hubble Guide Star Catalog. The first thing I noticed, was the chart was Epoch 1950. ... The coordinates were also exactly those on the ISR sticker, so I now knew that even though the ISR chart was epoch 1950, the coordinates on the sticker were epoch 1983. ...
