Scientists discover centuries old 'echo' from supermassive black hole
Scientists discover centuries old 'echo' from supermassive black hole
The universe appears to be speaking to us, after a centuries old “echo” from a supermassive black hole was detected by scientists. The black hole located inside the Milky Way became active around 200 years ago and produced a sound that is now being studied. The research was published in Nature and focuses on the black hole named Sagittarius A* (Sgr A*) found 26,000 light-years away from Earth. The noise was triggered when the object consumed gas and dust, with particles moving into the event horizon. The findings could teach us more about the activity of supermassive black holes, which continue to intrigue and confound scientists.

These results can further constrain the past activity of the galactic centre.” By their very nature, black holes are difficult to study as they absorb light around them, and these new findings offer insight into a fascinating part of space. Dr Marin said: “To get an idea of the increase in intensity of the X-ray emission when the black hole emerged from its quiescent state, it is as if a single glow-worm hidden in a forest suddenly became as bright as the Sun. “These findings explain why galactic molecular clouds near Sgr A* are shining more brightly than usual. It is because they are reflecting the X-rays emitted by Sgr A* 200 years ago.” Have your say in our news democracy.

UFO hunter claims a giant spacecraft is being hidden under a major landmark
UFO hunter claims a giant spacecraft is being hidden under a major landmark
A UFO hunter claims there is a huge spaceship hidden beneath one of the world’s major landmarks because it is “too big to move”. Ross Coulthart, an investigative journalist and UFO expert, said a “non-human” spacecraft is being stashed beneath a purpose-built structure – though he won't tell us where it is. Speaking in an interview, he said: “Some of these objects are not capable of being moved because they’re too bloody big.” Sign up to our free Indy100 weekly newsletter “I know exactly where it is. I thought it was b*****ks when I heard it, too.” Coulthart was previously a reporter on the news and current affairs program 60 Minutes on Channel Nine in Australia and has since gone on to write a number of books including In Plain Sight: An investigation into UFOs and Impossible Science. The UFO hunter community’s response to his claims has been a mixture of disbelief and desperation to find out where the landmark is. Some people seem to think it’s in South Korea, while others think it’s likely to be in an air defence military base. Coulthart has already made headlines this year after interviewing a whistleblower, who claimed that the US military had several crashed spacecraft in its possession, along with alien bodies. The Pentagon has said it hasn't discovered any information to substantiate this claim – but Congress is taking it seriously. In a twist that would have made even fans of The X Files raise an eyebrow, the Congressional House Oversight Committee is to hold a hearing on the issue next week after Republican congressmen and women promised to look deeper into the issue. House Speaker Kevin McCarthy was asked on Monday if he believes in aliens, in light of the hearing. "I will continue to see," McCarthy said. "But I think if we had found a UFO, I think the Department of Defense would tell us because they would probably want to request more money." "I'd love to see whatever facts and information we have," McCarthy added. "I'm very supportive of letting the American people see what we have, where we go." Have your say in our news democracy.

Flooding Sahara desert to create a brand new sea proposed as radical climate change solution
Flooding Sahara desert to create a brand new sea proposed as radical climate change solution
It might sound more like the kind of idle daydream billionaires like Elon Musk would have, but could flooding the Sahara actually be the best way of tackling climate change in the future? The idea of creating a new “sea” in Africa is being discussed, and it’s not the first time that the notion of a great oasis in the Sahara has been discussed among the scientific community. As the ongoing climate crisis continues to worsen, the notion of flooding vast areas of the desert is being returned to once again [via IFL Science]. A new “sea” was first proposed following the study of the Messinian salinity crisis – which saw a dried-out area of the Mediterranean rejuvenated by the Zanclean flood, reconnecting the Mediterranean Sea to the Atlantic Ocean around 5.33 million years ago. Sign up to our free Indy100 weekly newsletter Given how the Mediterranean was transformed by the flood, the idea of flooding the Sahara to achieve similar results has been thrown around in the scientific community as far back as 1877, the Scottish engineer Donald McKenzie suggested flooding the El Djouf basin in Western Africa. The idea is now returning to popularity as the world looks for solutions to the climate crisis. One proposal centres on the Middle East’s Dead Sea and flooding the area using water from the Red Sea to the Dead Sea Depression. A vast sea in Africa could represent a hugely innovative step towards tackling climate change and fostering a new hub of life – but even the people suggesting work such a project acknowledge just how expensive and dangerous it is. Even Y Combinator is a US startup accelerator who has described “desert flooding” as “risky, unproven, even unlikely to work”. Only time will tell whether the notion of a new sea in the Sahara coud ever work, or whether it’ll remain the stuff of dreams. Have your say in our news democracy.
