Inside the Covert World of Bootleg X-Ray Records. For decades, Soviet Russia banned pop, jazz, and rock and roll. These music lovers devised a solution: Music 'on the bone.' "Discarded x-rays...were made of plastic soft enough to be cut by the recording machine." http://www.nationalgeographic.com/magazine/2017/05/explore-xray-records/

Interacting Galaxies NGC 3447A and NGC 3447B

In this image, taken by the Hubble Space Telescope, you can see NGC 3447A and NGC 3447B. A pair of interacting galaxies located in the constellation of Leo (The Lion, https://goo.gl/GQSoe5), about 60 million light-years away from Earth.

NGC 3447B can be seen in the right part of the image, NGC 3447A is the smaller galaxy in the top left of the image.

The two galaxies are gravitationally distorting (https://goo.gl/ipKZIe) each other, and because of that it is hard to classify which type of galaxy they are. Both galaxies show what could be interpreted as disrupted spiral arms, but some categorize NGC 3447B as an irregular galaxy (https://goo.gl/Ixntg1).

NGC 3447 was discovered on March 18th, 1836, by the English astronomer John Herschel (https://goo.gl/WCo123).
