It feels like every time black holes are discussed and studied by the scientific community, there are new findings that blow our tiny minds. It’s been revealed that black holes actually regurgitate or “burp up” the stars that they eat years after the event. Experts made the discovery by studying tidal disruption events (TDEs). These events take place when stars are close enough to supermassive black holes, to be destroyed by the process of spaghettification. Studying these moments over a number of years after the black holes seemingly swallowing stars with no trace, the experts found that up to 50 per cent of them "burp up" the remains. Yvette Cendes is a research associate at the Havard and Smithsonian Center for Astrophysics and head author on the study. Speaking to Live Science, she said: "If you look years later, a very, very large fraction of these black holes that don’t have radio emission at these early times will actually suddenly 'turn on' in radio waves. "I call it a 'burp' because we’re having some sort of delay where this material is not coming out of the accretion disk until much later than people were anticipating." The material was re-emitted between two and six years from 10 out of 24 black holes which were studied by Cendes and the team. It has the potential to change the way the scientific community thinks about black holes. "There was a second peak, the two black holes re-brightened, and that's completely new and unexpected," Cendes said. "People were thinking that you'd have one outflow, and then it's kind of done. So this observation means these black holes can 'turn on' and then 'turn on' again." Meanwhile, a low intergalactic grumbling is emanating from deep space, according to scientists – and again, it’s black holes that are providing us with new discoveries. Astronomers say they detected the first-of-their-kind low frequency ripples, described as a “cosmic bass note” of gravitational waves, which is thought to be caused by supermassive black holes merging across the universe.

BROOMFIELD, Colo.--(BUSINESS WIRE)--Aug 2, 2023--

A South Korean firm has announced the world’s first production line for perovskite-silicon tandem solar cells, which promise an increase in efficiency of between 50-75 per cent compared to standard solar panels. The commercialisation of solar cells that use perovskite follows years of breakthroughs with the mineral, which has been hailed as a ‘miracle material’ for its potential to transform various industries, including renewable energy. Seoul-based Qcells said it will invest $100 million to roll out the next-generation solar cell technoloy, which until now has been limited to lab tests and academic research. The investment will fund a pilot production line at a factory in Jincheon, which is projected to be operational by late next year. “This investment in Jincheon will mark an important step in securing technological leadership,” said Qcells CEO Justin Lee. “With a global R&D network spanning from Korea, Germany and the US, Qcells will ramp up its efforts to produce high-efficiency advanced tandem cells.” Tandem solar cells are able to improve the efficiency of standard solar panels by splitting the light spectrum and optimising the harvesting of energy from each section into electricity. The current world record for solar cell efficiency is 32.5 per cent – meaning nearly a third of solar radiation is converted into eletrical energy – which was achieved with a perovskite-silicon tandem cell in December. By comparison, traditional silicon-based solar cells are currently only capable of reaching around 22 per cent efficiency. Qcells has so far succeeded in developing a tandem perovskite solar cell with a 29.3 per cent efficiency, which was achieved earlier this year in collaboration with German research centre Helmholtz-Zentrum Berlin.

Footage has claimed to show an odd figure knocking about on the surface of the Moon. In a video first shared in 2014, which has now accrued almost 7 million views, one YouTube user claimed there was a shadow caused by an "odd figure" on the surface, The video was made using Google Moon, a collection of millions of NASA images made public. Odd figure on the Moon? www.youtube.com The "figure" looks like a shadow created by any number of geological formations on the moon's surface. It certainly looks like a person, but the reason why people are seeing a figure is because of pareidolia, our tendency to see faces or other recognisable shapes in random formations. We have this trait as evolution has made us conscious of potential threats from dangerous animals. Either this, or the power of suggestion really is that powerful. So it probably isn't an alien, or some space tourist that has got up there without us knowing. But still, it is pretty freaky.
