The 2004 October Lunar eclipse, when the Earth's shadow cuts off sunlight from the face of the full Moon. The red colour is due to refraction of sunlight through the Earth's atmosphere, effectively a projection of all the sunsets on Earth.

A close up view of a group of sunspots (cool holes associated with magnetic activity). The dark umbra and surrounding penumbra are easily seen as is the granulation or mottled 'surface' of the photosphere of the Sun caused by convection currents. The larger spots are tens of thousands of Kilometres across. (Swedish 1m Solar telescope, La Palma) A close up view of a group of sunspots (cool holes associated with magnetic activity).

A large spiral galaxy (M104) in Virgo. The thick dust lanes in the spiral disc are most obvious in this well known view. (NASA, Hubble) A large spiral galaxy (M104) in Virgo. The thick dust lanes in the spiral disc are most obvious in this well known view. (NASA, Hubble)

The multiple ring structure is clearly seen with the dark Cassini Division two thirds of the way out. Th rings are made up of billions of small rocks and dust and form a plane only a matter of Kilometres thick, whereas they are over a hundred thousand Kilometres wide.

Vast pillars of dust and gas in M16, the Eagle Nebula in Serpens. Gravitational collapse of tiny 'drops' of these pillars will give birth to new stars.

Image taken by the Cassini spacecraft from the far side of Saturn. The Sun is hidden behind the planet and illuminates the ring system allowing new faint rings to be seen. The small blue dot seen between the rings at about 10 o'clock is the distant Earth. (NASA-Cassini) Image taken by the Cassini spacecraft from the far side of Saturn.
