Our understanding of the Sun may have completely changed after astronomers calculated that it might not be quite as big as we thought it was. The Sun is so powerful that it can disrupt the Earth’s magnetic field giving us the Northern Lights. It also continually baffles scientists, as one recent discovery found that part of the Sun is broken. Now, experts have discovered that the Sun may be a bit smaller than everyone thought, which could alter how we think of the star at the centre of our universe. Two astronomers made the calculation that the radius of the Sun is smaller, by a few hundredths of a per cent, than originally believed. The results, which are being peer-reviewed, are based on evidence gathered from sound waves that are made and trapped inside the burning hot sun. These sound waves are known as p-modes and they make noise like a growling stomach, suggesting a pressure change in the Sun’s interior. Analysing p-mode oscillations offers a “dynamically more robust” understanding of the Sun’s insides, according to astrophysicists Masao Takata from the University of Tokyo and Douglas Gough from Cambridge University. According to their research using evidence from p-modes, the solar photospheric radius is fractionally smaller than calculations made using the traditional reference model for the Sun’s seismic radius that analyses waves called f-modes. The reason for this difference is not very well understood. Astrophysicist Emily Brunsden told New Scientist: “To understand the reason for their difference is tricky because there’s just a lot of things going on.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.

A new, minimalistic £10 phone with features like digital payments and streaming unveiled by Indian billionaire Mukesh Ambani’s Reliance Jio could help expand internet services to a wider audience in the country. The affordable feature phone, priced at Rs 999 (about £10), can help bridge India’s “digital divide” by introducing 4G internet for the first time to scores of users, experts said. “Reliance Jio’s persistence to bridge the ‘digital divide’ by putting 4G internet-capable phones in hands of 2G feature phone users or first-time users continues!” industry analyst Neil Shah from the research firm Counterpoint said. Jio said in a press release earlier this week that the beta trial for its first million Jio Bharat phones would begin this week on Friday. The low-cost 4G-enabled phone with a 2-inch display comes with a number of pre-installed features. These include mobile payments through the United Payments Interface (UPI) – a form of instant digital payments that are widely used in India – as well as access to Jio’s own on-demand video and music streaming services JioCinema and JioSaavn. The low cost of the new phone may also bring the internet further within the reach of women in households. In low-income households in India, mobile phones remain a shared device with internet access shared on an individual mobile phone, explained digital rights activist Nikhil Pahwa, founder of tech policy analysis website MediaNama. “Typically, there is one person in the household whose mobile phone has internet access because devices are expensive and internet access prices have increased of late,” Mr Pahwa told The Independent. “So, a low-cost device means it will become affordable for low-income households to have more than one handset. This is great for women because typically it is the men in the house that have access to the internet,” he said. Reliance Jio said the phone will also come with a Rs 123 (£1.2) data plan valid for 28 days, offering 14GB of internet access (0.5 GB or 500 MB per day) – a price the company claims is 30 per cent cheaper than plans offered by competitors. This move may lead to other network operators in India such as Bharti Airtel reducing their tariffs too. “Bharti recently raised 2G prices from Rs99 to Rs155 across all circles while Vi [Vodafone Idea] took this in one circle. This disruptive step can halt incremental tariff increases for 2G and help JIO gain share in that segment,” JP Morgan said in a report on Tuesday. Following Jio’s announcement, shares for Bharti Airtel and Vi slipped by 2 to 3 per cent in early trading on Tuesday. The move also brings internet-enabled phones within the reach of the masses, and as more people understand the utility of the internet, it may lead to the further conversion of featurephone users to adopt smartphones, industry experts said. “There are still 250 million mobile phone users in India who remain ‘trapped’ in the 2G era, unable to tap into basic features of the internet at a time when the world stands at the cusp of a 5G revolution,” Reliance Jio Chairman Akash Ambani said. Telecom analyst Tarun Pathak tweeted that the featurephone-to-smartphone conversion in India has slowed down due to some “upgrade barriers”, adding that “Jio Bharat aims to bridge that gap”.

Vodafone customers say they are struggling to make calls, seemingly after technical issues at the network. Users said they were experiencing an array of unusual problems. Some said they were able to call other people on Vodafone – but not speak to people on other networks, for instance. Data connections appeared to be working as normal, however. On Twitter, Vodafone responded to affected users by apologising and asking for more information, and its online service checker indicated there were problems in some areas. The company did not immediately respond to a request for comment. Tracking website Down Detector also showed problems at Vodafone, starting on Monday afternoon. Other networks were also flagged as having issues – but that may be simply because Vodafone calls to those on other providers were failing to connect.
