Black Holes are messy eaters

New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.

Record-breaking fast radio burst offers path to weigh the Universe

Scientists report on their discovery of the most ancient and distant fast radio burst located to date, about eight billion years old. The discovery smashes the team's previous record by 50 per cent. It confirms that fast radio bursts can be used to measure the 'missing' matter between galaxies.
