Observations of “Jellyfish galaxies” with ESO’s Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly.

Any Earth sized world would most likely be unable to hold onto an atmosphere -- leaving its surface exposed to harmful stellar radiation and reducing its potential for habitability. *New clues in determining the size of a black hole Astronomers have discovered what could be an easy way to determine the size of a spiral galaxy’s supermassive black hole. They’ve found a direct relationship between the geometry of some types of spiral galaxies and the hidden super massive black hole at their centres. *Calm seas on Titan could mean smooth landing for future space probes Astronomers have determined that the lakes and seas on the Saturnian moon Titan have few waves higher than a centimetre. The findings mean the giant moon probably has little wind – the primary driving force for waves on the oceans of Earth. *Huge storm on Neptune Astronomers have detected a massive storm as big as the Earth on the ...

A new analysis of data from ESO’s Very Large Telescope and other telescopes suggests that the orbits of stars around the supermassive black hole at the centre of the Milky Way show the subtle effects predicted by Einstein’s general theory of relativity.
