PIX4612348: Galaxy of Hunting Dogs (M51) seen in X - The Whirlpool Galaxy seen in X - ray - The spiral galaxy M51 (NGC 5194) is located about 31 million years ago - light from Earth. This galaxy is double; two galaxies interact: the largest, NGC 5194, the smallest NGC 5195. X-ray image obtained by the Chandra space telescope on June 20, 2000. The Whirlpool Galaxy lies approximately 31 million light years from earth. This spectacular galaxy is paired with a smaller, more distant companion whose matter is being disrupted by the larger spiral in a gravitational tug of war. Eventually, the shape of both will be altered over many more millions of years. Image taken in X - ray by the Chandra space telescope on June 20, 2000 / Bridgeman Images

PIX4612954: Galaxy NGC 6670 in the Peacock - Galaxy NGC 6670 in Pavo - The galaxy NGC 6670, is about 400 million light years away from Earth in the southern constellation of Peacock. This system consists of two collision galaxies seen by the slice. Their nuclei are approximately 50,000 light years away. Image obtained by the Hubble Space Telescope on 30 October 2001. NGC 6670 is a gorgeous pair of overlapping edge - on galaxies. Scientists believe that NGC 6670 has already experienced at least one close encounter and is now in the early stages of a second. The nuclei of the two galaxies are approximately 50,000 light - years apart. NGC 6670 glows in the infrared with more than a hundred billion times the luminosity of our Sun and is thought to be entering a starburst phase. The pair is located some 400 million light - years away from Earth / Bridgeman Images

PIX4614997: Mars seen by the Hubble Space Telescope - 2016 - Mars in opposition 2016 - Image obtained on 12 May 2016 a few days before the opposition of Mars when the planet was only 80 million km away from Earth. This image shows planet Mars, as it was observed shortly before opposition in 2016, taken when the planet was 50 million miles from Earth on May 12, 2016. by the NASA/ESA Hubble Space Telescope. The photo reveals details as small as 20 miles to 30 miles across. This observation was made just a few days before March opposition on May 22, when the sun and Mars will be on exact opposite sides of Earth. Mars also will be 47.4 million miles from Earth. On May 30, Mars will be the closest it has been to Earth in 11 years, at a distance of 46.8 million miles. Some prominent features of the planet are clearly visible: the ancient and inactive shield volcano Syrtis Major; the bright and oval Hellas Planitia basin; the heavily eroded Arabia Terra in the centre of the image; the dark features of Sinus Sabaeous and Sinus Meridiani along the equator; and the small southern polar cap / Bridgeman Images
