LBY4572739: Les Catacombes, Paris 14th arrondissement. The origin of the catacombs dates back to the end of the 18th century, and collected all the bones found in the soil of Paris until around 1950. Anonymity is complete. It is estimated that six million of the individuals whose remains were collected in the catacombs. / Bridgeman Images
PIX4572892: Binary pulsar and gravitational waves - Artist's impression of the pulsar PSR J0348+0432 and its white dwarf companion - Artist's view of a gravitational wave generated by a system of a neutron star associated with a white dwarf, spreading on the fabric of space - time. This artist's impression shows the exotic double object that consists of a tiny, but very heavy neutron star that spins 25 times each second, orbited every two and a half hours by a white dwarf star. The neutron star is a pulsar named PSR J0348+0432 that is giving off radio waves that can be picked up on Earth by radio telescopes. Although this unusual pair is very interesting in its own right it is also a unique laboratory for testing the limits of physical theories. This system is radiating gravitational radiation, ripples in spacetime. Although these waves cannot be detected directly by astronomers on Earth they can be detected indirectly by measuring the change in the orbit of the system as it loses energy. As the pulsar is so small the relative sizes of the two objects are not drawn to scale / Bridgeman Images
PIX4573224: Exoplanets around 70 Virginis - A jovian planet orbiting 70 Virginis - Artist's view of the extrasolar planet 70 Vir B, a giant gas planet orbiting around a solar star, about 78 years old - light from the Sun. This exoplanet has about 6 times the mass of Jupiter and its distance from its star 70 Virginis is almost the same as that of Mercury from the Sun. A ringed 70 Vir B presides over the hot and airless terrain of a hypothetical moon. While it is not known if 70 Vir B has rings, it is certainly possible. 70 Vir B's rings would have no ice in them due to is proximity to its sun. Such rings would likely be less than 100 million years old and could have been formed from the shattered remnants of an asteroid that wondered too close to this giant planet. 70 Vir B's eccentric orbit would increase the likelihood of its encountering other objects in orbit around 70 Virginis. About 78 light years from the Earth astronomers believe that there is a large planet orbiting 70 Virginis, a type G5V star (similar to our own sun). Designated 70 Vir B, this planet is believed to have over six times the mass of the planet Jupiter and orbits around its sun in an eccentric orbit once every 116 days. 70 Vir B's average distance from its sun is about the same as that of the planet Mercury from our own sun / Bridgeman Images
PIX4572330: Variable star Mira Ceti view in ultraviolet - Star Mira Ceti seen in ultraviolet - Ultraviolet view of the star Mira of the Whale revealing a long train of material ejected by the large red star. This trail extends over 13 years - light. Mosaic of images obtained by the Galex satellite in November and December 2006. Ultraviolet image of the star Mira taken with the Galex satellite in November and December 2006. In this image, Mira is moving from left to right. It is visible as the small white dot in the bulb shape at right. The shed material can be seen in light blue. The dots in the picture are stars and distant galaxies. The large blue dot at left is a star that is closer to us than Mira. Mira is traveling so fast (130 kilometers per second) that it's creating a bow shock, or build - up of gas, in front of it, as can be seen here at right / Bridgeman Images

PIX4588652: Comet 67P/Churyumov-Gerasimenko and Philae - Comet 67P/Churyumov-Gerasimenko nucleus with Philae: Detail of the surface of the nucleus of Comet 67P/Churyumov-Gerasimenko as seen on September 2, 2016 by the Rosetta probe. The Philae lander appears pose on the comet - Rosetta's lander Philae has been identified in OSIRIS narrow-angle camera images taken on 2 September 2016 from a distance of 2.7 km. The image scale is about 5 cm/pixel - Philae's 1 m-wide body and two of its three legs can be seen extended from the body. The images also provide proof of Philae's orientation - A Rosetta Navigation Camera image taken on 16 April 2015 is shown at top right for context, with the approximate location of Philae on the small lobe of Comet Churyumov-Gerasimenko marked / Bridgeman Images
