Scientists confused after black holes 'burp up' previously destroyed stars
Scientists confused after black holes 'burp up' previously destroyed stars
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.

Bovington Tank Museum becomes unlikely YouTube hit with more views than the Louvre
Bovington Tank Museum becomes unlikely YouTube hit with more views than the Louvre
Who needs the Louvre in Paris or The Metropolitan Museum of Art in New York City when you've got Bovington Tank Museum? That's the opinion that YouTube have at least after the quaint military museum in Dorset became an unlikely hit on the video site, racking up more than 100 million views, more the the two aforementioned art institutes. The museum, simply known as 'The Tank Museum' currently has more than 500,000 subscribers to its YouTube channel. At the time of writing the channel has more than 400 videos with some of the most popular being short documentaries on the history of such tanks as 'The War Horse' and 'King Tiger' which both have more than 2 million views each. As per the New York Times, the channel is the first ever museum to achieve more than 550,000 subscribers on YouTube and the first to have more than 100 million views. The museum was founded in 1923 but much of its success in the digital age has come via viewers in the United States and Canada who have become entranced by series on the channel such as top 5 lists and 'Tank Chat.' Top 5 Tanks | Chris Copson | The Tank Museum www.youtube.com One of the stars of the channel is the museum's education officer and full-time presenter Chris Copson who told the BBC that he would never have dreamed "in a million years" that he would become an online celebrity and says that he has even been recognised in the street. Nik Wyness, the museum’s head of marketing, admitted to NY Times that the YouTube phenomenon has helped the museum financially and generated a third of their revenue last year, which helped boost merchandise sales on their online store. It's not just YouTube where things are thriving for the Tank Museum. Their TikTok account is also growing with an impressive 320,000 followers so far.
