PIX4583964: Inhabited mission to an asteroid - Artist's view - The MPCV spacecraft approaches an asteroid - This capsule should be able to take a crew of six astronauts to an asteroid, the Moon or to take men to Mars. Here, the vehicle is connected to an additional housing module for a duration of more than three months, as well as to a module for extravehicular outputs equipped with two MVs (Manned Maneuvering Vehicles). The Multi-Purpose Crew Vehicle (MPCV) is a spacecraft project currently being developed by Lockheed Martin for NASA. Based on specifications and tests already performed for the Orion spacecraft. It was announced by NASA on 24 May 2011. A Deep Space Vehicle (DSV) with an Extended Stay Module (ESM) and Manned Maneuvering Vehicles (MMVs) approaches a small asteroid / Bridgeman Images

PIX4584039: Inhabited mission to an asteroid - Artist's view - Asteroid Lander EVA egress - Astronauts leave a spaceship on the surface of an asteroid. A pair of explorers in space suits exit an Asteroid Lander in preparation for exploring the asteroid's surface. The surface gravity is so low that in terms of moving about the experience is more akin to exploring the floor of an ocean than the airless surface of a celestial body. The explorers' space suits include miniaturized manned maneuvering units to, i.e., tiny reaction control thrusters, to propel them across the asteroid's surface / Bridgeman Images

PIX4584755: Stellar black hole - Artist view - Stellar black hole - Artist view - A stellar black hole is born from the gravitational collapse of a massive star. The stellar black holes have a mass of some solar masses. A black hole is a region of space whose gravitation is so strong that it will prevent any form of material or radiation from escaping. A stellar black hole is a black hole formed by the gravitational collapse of a massive star; it is also a region of space in which the gravitational field is so powerful that nothing can escape / Bridgeman Images

The meridian line and the obelisk - Established in 1744 by Claude Langlois under the direction of astronomer Pierre Charles Le Monnier, the meridian consists of a 40.3 m long copper band, which starts from a marble slab in the south transept and joins the obelisque in the north transept. A lens placed in the stained glass window of the south transept allows the Sun to illuminate the Meridian. At the summer solstice, a bright spot illuminates the marble slab; at the winter solstice, the light spot illuminates the obelisque / Bridgeman Images

PIX4585211: Equatorial sundial - Equatorial Sundial - The equatorial sundial has the particularity of having its graduation table located in the plane of the Earth's equator. As a result, the style (the metal stem that gives the shade) is perpendicular to the table, although always directed towards the polar star. In an equatorial sundial, the planar surface that receives the shadow, is exactly perpendicular to the gnomon's style. This plane is called equatorial, because it is parallel to the equator of the Earth / Bridgeman Images

This dial shows the local solar time, numbered at the bottom in Roman numerals. The declination lines are drawn in dots and bear the signs of the Zodiac at their extremity. Some lines have a chaotic trace, the effect of the unfortunate restoration of 1988. This dial dates from the construction of the tower, around 1679.
