The blue of the jet contrasts with the yellow glow from the combined light of billions of unseen stars that make up the galaxy, which lies 50 million lightyears away.<\/p>\n

The yellow blobs in these images are giant elliptical galaxies roughly 2 to 4 billion lightyears away, each outlined with the blue light of a background galaxy twice as distant.<\/p>\n
The gravity of the closer galaxy has deflected the background light into Einstein rings.<\/p>\n

This picture is one of Hubble\u2019s most striking examples of gravitational lensing<\/a>.<\/p>\n
Here, the gravitational field of a yellow foreground galaxy cluster<\/a> 5 billion lightyears away has bent the light of a background galaxy 10 billion lightyears away into a graceful blue arc.<\/p>\n

Data from Hubble and the Chandra X-ray observatory combine in this image of galaxies colliding in the Bullet Cluster.<\/p>\n
It shows that most of the mass of galaxies is separate from the cluster\u2019s hot gas, which is shown in pink. From this astronomers infer the presence of dark matter<\/a> in the areas coloured blue.<\/p>\n

As well as Einstein rings, Hubble has also spotted Einstein crosses.<\/p>\n
Here a yellow supernova<\/a> 9.3 billion lightyears away has been repeated four times around the edge of a closer galaxy due to the latter\u2019s immense gravitational field.<\/p>\n

Astronomers believe a huge black hole lies at the centre of the dwarf galaxy M60-UCD1.<\/p>\n
Located 54 million lightyears away, it\u2019s one of the smallest known galaxies with a supermassive black hole.<\/p>\n

This doughnut shape is an 800 lightyear-wide disc of dust fuelling a black hole at the centre of galaxy NGC 4261.<\/p>\n
The doughnut is calculated to be 1.2 billion times the mass of the Sun while the black hole\u2019s gravity<\/a> is capable of pulling in enough surrounding material to make 100,000 stars like our Sun.<\/p>\n

This is Hubble\u2019s deepest-ever view of the Universe, revealing the shape of thousands of galaxies as they would have appeared 13.2 billion years ago, just 500 million years after the Big Bang.<\/p>\n
It shows that form and structure have existed for a very long time.<\/p>\n

The dark cross across the core of the nearby spiral galaxy M51, the Whirlpool Galaxy<\/a>, is due to dust and marks the position of a black hole.<\/p>\n
The two arms of the dark X are edge-on dust rings 100 lightyears in diameter.<\/p>\n
