Einstein was the first person to propose that ‘empty space’, which does not contain matter or radiation, is not actually empty and in fact has a residual energy. This empty space is also capable of creating more space from itself. (Credit: benmoat/Shutterstock)

The Rosetta spacecraft is scheduled to rendezvous with Comet 67P/Churyumov-Gerasimenko on Wednesday. If all goes according to plan, Rosetta will become the first probe ever to orbit a comet — and, in November, the first to drop a lander onto the surface of one of these icy wanderers. (Credit: ESA)
The room that exposed a laboratory technician to a massive dose of radiation, which led to him being known as the “Atomic Man”, is to be entered for the first time since the incident in 1976. (Credit: AP)

This is an illustration of the physical, spatial and temporal picture for the outflows emanating from the vicinity of the super massive black hole in the galaxy NGC 5548. The behavior of the emission source in five epochs is shown along the time axis. The obscurer is situated at roughly 0.03 light years (0.01 parsecs) from the emission source and is only seen in 2011 and 2013 (it is much stronger in 2013). Outflow component 1 shows the most dramatic changes in its absorption troughs. Different observed ionic species are represented as colored zones within the absorbers.
