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.

LOS ANGELES--(BUSINESS WIRE)--Jun 29, 2023--

Frankenstein’s monsters aren’t just for Halloween, as a team of US scientists have recently discovered. The experts at Northern Kentucky University (NKU) were tasked with analysing the remains of a supposed mummified “mermaid”, and what they found was pretty gruesome. The mummy was brought to America from Japan more than 100 years ago after being donated it to the Clark County Historical Society in Springfield, Ohio. It arrived at the society in 1906 but documents supplied alongside the strange specimen suggest it dates back to the mid-1800s. This means that for some 170 years, the true identity of the wisened, 29-cm-long creature remained a mystery. However, thanks to modern technology, the team at NKU has finally worked out that the sinister-looking “siren” is, in fact, a ghoulish hybrid of monkey, fish and lizard. Joseph Cress, who led the project, told Live Science that he and his colleagues used X-ray and CT scans to investigate the creepy cadaver. "This allowed us to see [the mummy] in almost every dimension in the hopes to see what was inside it," he explained. They determined that that the “mermaid” consists of the head and torso of a monkey sewed onto the body of a fish, and its “hands” are the clawed legs of a lizard – most likely a Komodo dragon. The scans also revealed a pair of wooden stakes hidden inside the chimeric corpse – one running from head to tail and another across the shoulder blades — which were presumably inserted to keep the monster in one piece. Cress and his colleagues are currently trying to reconstruct a more detailed model of the mermaid and its individual components, according to Live Science. Once these models are complete, they plan to send them to zoos and aquariums to help confirm the different parts on a species level. However, jaw-dropping this specimen may be, it's not the only “mermaid” to be debunked in recent times. In March 2022, researchers analysed a similar example that was found in a hidden box in a Japanese temple. They also expected the creature, which was 30.5 cm long and dated back to the mid-1700s, to be a monkey-fish hybrid. However, tests conducted in February this year revealed that it was, in fact, predominantly made of cloth, paper and cotton. It had been painted with sand and charcoal and held together by metal pins, while various animal parts, including fish skin and mammal hair, had been stuck to it. Experts believe that the two “mermaids” were made to resemble "ningyo" — hideous fish-like creatures with human heads and sharp claws from Japanese mythology. According to legend, a nun named Yaobikuni lived for 800 years and retained the youthful appearance of a young woman, after eating a ningyo. Her immortality made the creatures a symbol of longevity, so it’s likely that fraudsters tried to recreate the mermaids to sell them to wealthy seekers of immortality. Still, at least the owners of these two examples didn’t make the mistake of trying to eat them. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

TOKYO--(BUSINESS WIRE)--Jul 5, 2023--

WhatsApp is changing the way billions of users log into the messaging app, ditching passwords and two-factor authentication in favour of quicker and more secure passkeys. The move is part of a major shift within the tech industry to move away from decades-old password technology and replace it with the more modern passkey format, which combines biometric information like fingerprints with a simple numeric code in order to identify people. A similar switch was recently announced by Google, which will introduce passkeys to its apps like Maps, Search and YouTube. WhatsApp’s update will only impact Android users to begin with. “Passkeys are a new way to log back into your account,” said Will Cathcart, who heads WhatsApp. “This is a more secure way of confirming it’s really you – and gives you an added layer of security.” WhatsApp is also rolling out self-destructing voice notes to users as part of new measures to improve privacy on the world’s most popular messaging app. The update is currently only available for beta tester users who have the latest version of WhatsApp installed on their phone or computer, though it is expected to eventually be introduced for all users. With more than 2.7 billion users worldwide – the majority of which on Android devices – WhatsApp updates typically need to be introduced gradually in order to make sure any potential security bugs do not have a critical impact. The self-destructing audio messages, first spotted by WhatsApp feature tracker Wabetainfo, is compatible with both Android and iOS users, though no date has been given for when a wider roller out might be expected. WhatsApp does not comment on release schedules for feature updates unless they relate to security. “After sending the voice note with view once mode enabled, you won’t be able to listen to it and the recipient can no longer listen to the voice note after dismissing it,” Wabetainfo noted. “This mode effectively minimises the chances of unauthorised access or later listening, providing a new layer of privacy for sensitive and confidential information.” The latest update follows recently added features like ‘Channels’, which allow people to follow celebrities and companies within the app, and a ‘Create’ button that gives users the ability to make custom art on the platform. The Create feature brings generative artificial intelligence to WhatsApp for the first time, and means users do not require external tools or specific design skills to create the stickers. Instead, the custom stickers can be produced using simple text-based prompts, similar to other AI image generators like Midjourney and OpenAI’s Dall-E.
