The first picture of a black hole The EHT telescope, a terrestrial telescope network that combines data from electromagnetic interference stations located on the Earth, just gave the first picture of a black hole: the supermassive black hole in M87 *, mass estimated between 5,8000000000 7,2 billion times greater than the Sun and located in the heart of the elliptical galaxy M87.- Travel the milky way The Canadian Dave Chuck used thousands of photos from NASA's Spitzer Space Telescope, to create this amazing video that allows us to go in our Galaxy.
- A detailed picture of the Andromeda Galaxy from the Hubble telescope On January 5, the NASA pulled with the Hubble space telescope the largest photo by Andromeda Galaxy. The photo contains over 100 million stars, not only is the best view of the Andromeda galaxy that have until now, but the larger picture that has ever taken with Hubble. Despite the fact that the galaxy is 2,5 million light years away, spans an area larger than the full moon we see in the sky, and to create such a detailed picture should be pulled 7,398 photos. The analysis of the final image was 1,5 million pixels (69.536 x 22.230) and had a size of 4,3 GigaBytes.

- The book with three-dimensional images David Minkin collects antiques. Here he presents his latest acquisition, a book-tunnel dating from the 19th century.
