Nasa scientists have found a planet they believe is covered by active volcanoes. In a study published in the journal Nature, scientists said they found the planet, which is the size of Earth about 90 light-years from Earth in the Crater constellation. They called it LP 791-18 d and one part is constantly scorched by sunlight, while the other is always in darkness. “The day side would probably be too hot for liquid water to exist on the surface. But the amount of volcanic activity we suspect occurs all over the planet could sustain an atmosphere, which may allow water to condense on the night side,” Björn Benneke, one of the astronomers who studied the planet, told NASA’s Jet Propulsion Laboratory. Sign up to our free Indy100 weekly newsletter The LP 791-18 system contains at least two other planets, called LP 791-18 b and c. The latter is two-and-a-half times larger than Earth and more than seven times its mass. It also affects the orbit of LP 791-18 d, making it travel along an elliptical path around the system’s sun. That path means LP 791-18 d is deformed every time it completes an orbit. “These deformations can create enough internal friction to substantially heat the planet’s interior and produce volcanic activity at its surface,” according to NASA. “A big question in astrobiology, the field that broadly studies the origins of life on Earth and beyond, is if tectonic or volcanic activity is necessary for life,” study co-author Jessie Christiansen said. “In addition to potentially providing an atmosphere, these processes could churn up materials that would otherwise sink down and get trapped in the crust, including those we think are important for life, like carbon.” Have your say in our news democracy.

OpenAI has launched a ChatGPT app for iPhone users amid a surge in fake versions of its hugely popular AI chatbot. The free app is the first official OpenAI product to appear in app stores, though dozens of imitation versions seeking to mislead or scam users are currently available for iOS and Android users. The new ChatGPT app is available immediately in the US and will roll out to other countries in the coming weeks, OpenAI said, with an Android version of the ChatGPT app also under development. “With the ChatGPT app for iOS, we’re taking another step towards our mission by transforming state-of-the-art research into useful tools that empower people, while continuously making them more accessible,” OpenAI wrote in a blog post detailing the new app. “We’re eager to see how you use the app. As we gather user feedback, we’re committed to continuous feature and safety improvements for ChatGPT.” Users who download the app will have access to their ChatGPT account history from the web, as well as access to OpenAI’s open-source speech-recognition system Whisper. This will allow people to speak to the artificial intelligence tool for the first time. Subscribers to ChatGPT Plus will also get access to the more advanced GPT-4 tool, as well as faster response times compared to free users. Last month, researchers noted an “alarming” number of scam apps had appeared within the MacOS App Store, while Google’s Play Store is still inundated with unofficial ChatGPT apps. “Most of these apps are nothing but cheap imitations or outright scams that fail to deliver on their promises,” privacy researcher Alex Kleber wrote in a report published in April. “These scams not only deceive users but also tarnish the reputation of legitimate developers and hinder the growth of the app ecosystem on the MacOS platform.” OpenAI has applied to patent the GPT acronym in an effort to crackdown on the concerning trend, however the US Patent and Trademark Office refused to fast-track the request last month.
