Scientists have found a new planet they shouldn’t exist, after it seemed to miraculously survived the violent death of its star. Many planets, including our own, face almost certain doom when their stars reach the end of their lives and engulf them. When our own Sun dies, for instance, it will expand to 100 times and swallow the Earth. But the new study offers hope that at least some of those planets are able to survive. The newly discovered world, a Jupiter-like planet known as Halla, managed to survive the demise of its star Baekdu, in what should have been certain death. Astronomers found the planet and discovered through follow-up observations that Baekdu had previously expanded into a red giant. When it did, it would have inflated up to 1.5 times the distance between it and Halla, engulfing the star, and then shrunk back down to its current size. Despite that dramatic and violent event, Halla has managed to persist, sticking around so that astronomers could see it using telescopes in Hawaii. “Planetary engulfment has catastrophic consequences for either the planet or the star itself - or both. The fact that Halla has managed to persist in the immediate vicinity of a giant star that would have otherwise engulfed it highlights the planet as an extraordinary survivor,” said Marc Hon, the lead author of the study. The findings are published in a new paper, ‘A close-in giant planet escapes engulfment by its star’, in the journal Nature today. Halla was found in 2015, using what scientists call the “radial velocity method”, which monitors how stars move and uses that to understand how they might be tugged around by the planets that orbit them. In the years since, scientists found that the planet must have been engulfed by the star, and conducted follow-up observations to better understand the planet. Those observations confirm that the planet had been in its stable orbit for over a decade, and that it really existed. “Together, these observations confirmed the existence of the planet, leaving us with the compelling question of how the planet actually survived,” said IfA astronomer Daniel Huber, second author of the study. But scientists still do not know how it survived. One possibility is that it started on a larger orbit before moving closer to its star, but astronomers believe that is unlikely. Another is that Baekdu was actually once two stars. They may have merged during their death, sparing Halla from being merged at all, by stopping them getting big enough to engulf it. And a separate possibility is that Halla was actually born out of the collision of the two stars. That might have produced a gas cloud that actually gave birth to Halla, and so it may be the result of the demise of its star rather than a survivor of it.

Former Tory leader Sir Iain Duncan Smith has warned the merger between Vodafone and Three is “dangerous” and risks giving a company with its roots in Communist Party-ruled China a more prominent place in the UK’s mobile network. The former work and pensions secretary and MP for Chingford and Woodford Green said the proposed deal raised serious questions about national security and competition within the UK telecommunications market. Vodafone and Three, both of which have millions of customers in the UK and Ireland, announced earlier this month that they were joining forces in a multibillion-pound deal they said would create one of Europe’s biggest 5G networks. “This is a dangerous deal, which it seems is yet another example of how the Communist Party is trying to create a Western dependency on China,” Sir Iain told The Independent. “Not only does it raise important questions about competition, but it poses risks to our communication networks and personal data.” Three is owned by CK Hutchison, a Hong Kong-listed conglomerate that has been accused of supporting repression in the former British territory, where thousands of residents fled after China’s implementation of a sweeping national security law used by authorities to crack down on dissent against the regime in Beijing. Sir Iain is among a number of cross-party MPs to raise concerns about the growing influence of China in the West, and in particular, telecoms companies who have their headquarters there and are operating in the UK. “The government still doesn’t seem to understand that Chinese companies can be mandated to hand over their data to Beijing at the drop of a hat,” Sir Iain said. “We should be really worried about that. I also think we need to be taking a closer look at who owns these companies, the links between them and the Chinese government and the origins of the money flowing through them.” Last autumn the government announced that Shenzen-based Huawei technology must be removed from the UK’s 5G public networks by the end of 2027, It followed advice from the National Cyber Security Centre and pressure from Washington, which banned equipment made by the company because it posed an “unacceptable risk” to US national security. In March, prime minister Rishi Sunak warned that China plans to “reshape the world” in plans that posed an era-defining challenge for the UK and its allies in the West but dismissed calls for Beijing to be categorised as a threat, something his predecessor Liz Truss pushed for. The union Unite, which has 1.4 million members, is also campaigning against the merger, which some analysts say could result in job losses and higher prices for consumers who are already being squeezed by the cost of living crisis. The deal has triggered an initial investigation by the Competition and Markets Authority and will be subject to approval under the new National Security and Investment Act. Gail Cartmail, Unite’s executive head of operations, said: “Instead of idly watching the CK Group cream profits from UK businesses, the government should ask if they are a suitable custodian of British assets.” Charlotte Nichols, the Labour MP for Wigan North who sits on the Department for Business and Trade sub-committee on national security, said: “Unite the Union has shared research with me that shows this merger would leave sensitive government contracts and the data of millions of UK consumers in the hands of Three, a company whose key leadership have supported repression in Hong Kong and worked hand-in-hand with the Chinese state for decades. “This will be dangerous deal for the UK and I fully support Unite’s campaign against it.” Other MPs – both Labour and Conservative – have tabled questions to government departments asking what security assessments ministers have made of the proposed merger deal. Both Three and Vodafone refused to comment but have previously dismissed concerns about security, saying that they work closely with security bureaus in what is a regulated industry. The Cabinet Office has said it welcomes foreign trade and investment “where it supports growth and jobs in the UK, meets our stringent legal and regulatory requirements, and does not compromise our national security. “However, we will not hesitate to use our powers to protect national security where we identify concerns.” Read More Vodafone and Three to merge in multibillion-pound deal Vodafone and Three merger: What the huge deal actually means for you Cleverly defends China visit plans and pledges to use UK’s global ‘influence’ Three and Vodafone are merging.
