... 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. ... Part 2...

... It is found that the correlation coefficients between these two parameters calculated separately inside and outside the sunspot formation zone ±30 have cyclic variation and occur in anti-phase. This suggests different mechanisms of formation of the corona in the fields of small, medium, and large scales. ... The relationship between the coronal green line brightness (CGLB) and the magnetic field strength (MFS) has been investigated by constructing the corresponding synoptic maps for the 1977-2001. ...

Solar Eclipses Notice that both the Sun and the Moon appear in the sky to be about the same size: half of a degree. ... The Earth would cast a shadow on the Moon when they were all three lined up. When the Moon blocks the Sun, we call it a solar eclipse. The other eclipse is when the Sun-EarthMoon lineup is in effect, and the Earth blocks the Moon. ... Lunar eclipses, however, are easier to see, since the shadow of the Earth on the Moon is quite large. ...

Each image was taken through a different colour filter. From left to right, the images show how Betelgeuse appears in red (a wavelength of 700 nanometres), very near-infrared (905 nm), and near-infrared (1290 nm) light. To show this, we have coloured the images different shades of orange and red. 700 nm . ...
