  This plot compares the colours of Solar System planets to the colour of the hot Jupiter HD 189733b. With the exception of Mars, the colours are primarily determined by the chemistry of the planets' atmospheres.

  This image shows a near-infrared-light image of a brown dwarf located 170 light-years away from Earth.The object is no more than 30 times the mass of Jupiter, making it too small to sustain nuclear fusion to shine as a star

  This new image from the NASA/ESA Hubble Space Telescope captures two galaxies of equal size in a collision that appears to resemble a ghostly face.
• 

  This diagram compares observations made with the NASA/ESA Hubble Space Telescope of two 'hot Jupiter'-class planets orbiting very closely to different sunlike stars. Astronomers measured how light from each parent star is filtered through each planet's atmosphere.

  The NASA/ESA Hubble Space Telescope captures the iridescent tapestry of star birth in a neighbouring galaxy in this panoramic view of glowing gas, dark dust clouds, and young, hot stars.

  The ghostly shells of galaxy ESO 381-12 are captured here in a new image from the NASA/ESA Hubble Space Telescope, set against a backdrop of distant galaxies.
