A bright meteor (shooting star) originating from the 'Radiant' in Leo captured during the Leonid storm of 2001. Here a tiny (mm) dust particle left by Comet Temple-Tuttle vapourises at around 80km altitude. In the background is Orion's belt (top) and the Orion Nebula (M42). (Brown) 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. (Venturin) The storm clouds and Great Red Spot, a 2000mph hurricane, larger than the Earth which survives as 'order' among the chaotic flow of Jupiter's belts of rotating gas. (NASA, Hubble)
Also known as the Northern Lights, this picture shows the interaction of the Solar Wind and the Earth's Magnetic field. Taken in November 2004 (Venhaus). The end of a star (similar to the Sun). A White Dwarf remains at the centre of a shell of exploding gas (the original outer layers of the old star). The colours are due to the presence of different elements.(NASA,Hubble) The innermost of the Galilean moons of Jupiter, coloured due to its sulphurous, volcanic surface, crosses in front of the parent planet, preceded by its sharp black shadow. (NASA, Hubble)
Dark Matter Ring - Credit: NASA HST Detailed view at closest approach in August 2003. Showing the Southern Ice cap and many surface features. (NASA, Hubble)
An insiders panoramic projection of our own spiral galaxy the Milky Way. (NASA, Hubble) Billions of light years away Hubble glimpses a dense and different Universe full of young galaxies at an early stage of formation after the Big Bang. (NASA, Hubble) 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)
A wonderful explosion of colour (in Gemini) as an old star dies leaving a central tiny, hot, White Dwarf and several layers of exploding gas (NASA, Hubble) A spiral galaxy showing a ring of young blue stars and the pink hydrogen clouds from which they form. (NASA, Hubble)
Orion's Belt - Credit: NASA/ESA/ESO A super massive star undergoing the final convulsions of instability before exploding. Its outer layers darkenend by Carbon and heavy elements. (NASA, Hubble) 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. (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. (NASA, Hubble) A view of the very centre of our Galaxy, the Milky Way showing densely packed old highly evolved stars. The black hole Sagitarius A is in the central square surrounded by rapidly orbiting Red Giant stars. 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 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) 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. (NASA, Hubble)
