16 Aug 2017, 17:00 UTC 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.

The findings reported in the Astrophysical Journal represent one of the deepest ever observations into the 13.8 billion year old universe. *Cassini begins its final orbits around Saturn NASA's Cassini spacecraft has entered new territory in its final mission phase, the grand finale, as embarks on a set of ultra-close passes through Saturn's upper atmosphere with its final five orbits around the ringed world. Cassini completed the first of these five passes over Saturn on Monday. *The ancient Earth was a water world A new analysis of mineral grains indicates that the ancient Earth was most likely a water world -- barren, flat, and almost ...

11 Aug 2017, 06:31 UTC Stream episodes on demand from www.bitesz.com (mobile friendly) * An Earth-like atmosphere may not survive Proxima b's orbit Proxima B -- the nearest known exoplanet to our solar system is probably a dead world despite being in the habitable zone of its host star Proxima Centauri. 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 ...

9 Aug 2017, 10:00 UTC 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.

The study based on evidence of the iron 60 isotopes in meteorites indicate that a supernova shock wave is still the most-plausible origin story for explaining the short lived radioactive isotopes in our Solar System *A new window in the hunt for molecular signatures in deep space Astronomers have begun using one of the precursor radio telescopes for the Square Kilometre Array project to study molecular signatures which could lead to the detection of complex molecules that are precursors to life. The team are using the Murchison Widefield Array to undertake the observations focusing on the molecular gas and dust clouds from which new generations of stars are born. *New clues about superluminous supernovae Astronomers have detected an extraordinarily bright supernova in a surprising location. ...
