PIX4582885: Remains of the supernova of the Sails - Detail - Vela supernova remnant. Detail - Detail of the rest of the supernova of the Sails. The supernova exploded 12,000 years ago. A supernova event marks the catastrophic end - point in the life of a massive star. The self - destruction of the star releases a huge amount of energy as radiation of all kinds, but a substantial fraction of the force of the explosion blasts the outer part of the supernova into an expanding shell of matter that travels through the almost empty space between the stars. As the rapidly moving blast wave encounters the relatively stationary interstellar medium it creates a very narrow, luminous shock front that appears as a faint nebula. Because the shock front is very convoluted the nebulosity appears to be highly structured and the various colours define different energy levels within the interaction. Although the star responsible for the Vela supernova remnant exploded 12,000 years ago, it is still affecting its environment / Bridgeman Images
PCT4295517: Cerdagne electric railway line: construction of the Gisclard bridge (or bridge of La Cassagne), crossing the Tet valley near Mont-Louis and Fontpedrouse, just after its construction: pilar and shrouds - Roussillon, Catalan country, Pyrenees-Orientales (Pyrenees Orientales) - this line opened in 1910, has been registered by UNESCO since 2002 on the indicative list of the World Heritage as “” Cerdagne Railway””. Operated by SNCF, it forms the 669 000 line of the national railway network - This cable bridge was designed by Genie Commander Albert Gisclard. A device of his invention completely avoids oscillations and allows the train to pass safely. It is the only railway suspension bridge still in operation in France. Tragic irony of fate, Commander Gisclard lost his life in a derailment of the train during a test trip near the bridge in 1909 - phototyping Labouche, early 20th century - / Bridgeman Images

PCT4295492: Cerdagne electric railway line: the small yellow train on the Gisclard bridge (or Cassagne bridge), crossing the Tet valley near Mont-Louis and Fontpedrouse - Roussillon, Catalan Country, Pyrenees-Orientales (Pyrenees Orientales) - this line opened in 1910, has been inscribed by UNESCO since 2002 on the Tentative List of World Heritage in as “” Cerdagne Railway””.

PIX4596946: Apollo 13: astronauts return - Apollo 13 crew return - Astronaut John L. Swigert Jr. is hoisted aboard a helicopter to be taken aboard the USS Iwo Jima airplane door. Astronaut Jim Lovell is still in the inflatable boat. April 17, 1970. Astronaut John L. Swigert Jr., command module pilot, is lifted aboard a helicopter in a “Billy Pugh”” net while astronaut James A. Lovell Jr., commander, awaits his turn. Astronaut Fred W. Haise Jr., lunar module pilot, is already aboard the helicopter. In the life raft with Lovell, and in the water are several U.S. Navy underwater demolition team swimmers, who assisted in the recovery operations. The crew was taken to the USS Iwo Jima, prime recovery ship, several minutes after the Apollo 13 spacecraft splashed down at 12:07:44 p.m. (CST), April 17, 1970 / Bridgeman Images
PIX4582923: Remains of the supernova of the Sails - Detail - Vela supernova remnant. Detail - Detail of the rest of the supernova of the Sails. The supernova exploded 12,000 years ago. The line that crosses the image is the trace left by the passage of a satellite during the photo shoot. Image obtained with Siding Spring's 3.9m telescope. A supernova event marks the catastrophic end - point in the life of a massive star. The self - destruction of the star releases a huge amount of energy as radiation of all kinds, but a substantial fraction of the force of the explosion blasts the outer part of the supernova into an expanding shell of matter that travels through the almost empty space between the stars.
