Black holes are the sources of the strongest gravitational fields that can be found today in the Universe and are ideal laboratories for testing Einstein’s theory of general relativity in the strong field regime. In his article, Professor Bambi shows that the possibility of an interstellar mission to send a small spacecraft to the nearest black hole, although very speculative and extremely challenging, is not completely unrealistic.

This Hubble image shows of the outer arms of NGC 45, a spiral galaxy some 22 million light-years away in the constellation of Cetus. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) instrument. It is based on data obtained through seven filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.
