Shaheed worked with TOLOnews, one of Afghanistan’s largest broadcasters, for more than a decade. “Where in the Islamic countries do journalists work like that? This is very painful and upsetting.” “I hope these difficult days pass,” said Shaheed. In an interview with VOA’s Dari service, Shaheed said the Taliban mandate that women cover their faces when reporting is “not acceptable.”
Source: Do Kepler Superflare Stars Really Include Slowly Rotating Sun-like Stars?-Results Using APO 3.An award-winning journalist who fled from Afghanistan last August says the international community must not remain silent on Taliban restrictions for female journalists.Īnisa Shaheed, a former TOLOnews broadcaster who on May 23 was named as an International Center for Journalists’ Knight awardee, says she is troubled by orders that impact the ability of female journalists to work. Now, it’s a much bigger problem because of our electronics.īottom line: New research suggests a superflare could happen on our sun. If a superflare occurred 1,000 years ago, it was probably no big problem. Still, that could give humans time to prepare, protecting electronics on the ground and in orbit from radiation in space. But he said that it’s a matter of when, not if. Notsu can’t be sure when the next big solar light show is due to hit Earth. For the sun, it’s once every few thousand years on average. Young stars have superflares once every week or so. But older stars like our sun, at 4.6 billion years old, aren’t off the hook.
Based on the team’s calculations, younger stars tend to produce the most superflares. To find out, Notsu and an international team of researchers turned to data on superflares from the European Space Agency’s Gaia spacecraft and from the Apache Point Observatory in New Mexico. But we didn’t know if such large flares occur on the modern sun with very low frequency. When our sun was young, it was very active because it rotated very fast and probably generated more powerful flares. And, Notsu said, that data raised an obvious question: Could a superflare also occur on our own sun? Notsu said: But what the Kepler data was showing seemed to be much bigger, on the order of hundreds to thousands of times more powerful than the largest flare ever recorded with modern instruments on Earth. Notsu explained that normal-sized flares are common on the sun. In rare events, the light from distant stars seemed to get suddenly, and momentarily, brighter. The spacecraft, which looks for exoplanets circling distant stars, also found something odd about those stars themselves. Scientists first discovered superflares via NASA’s Kepler Space Telescope. But there is some possibility that we could experience such an event in the next 100 years or so.
Our study shows that superflares are rare events. Such a blast could disrupt electronics across the globe, causing widespread blackouts and shorting out communication satellites in orbit. That’s because if a superflare erupted from the sun, he said, Earth would likely sit in the path of a wave of high-energy radiation. Notsu said the study results should be a wake-up call for life on our planet. University of Colorado researcher Yuta Notsu is the lead author of the peer-reviewed study, published May 3, 2019, in The Astrophysical Journal. Now, new research suggests superflares can also occur on older, quieter stars like our own sun, albeit more rarely, perhaps once every few thousand years. Until recently, researchers assumed that such explosions occurred mostly on stars that, unlike Earth’s sun, were young and active. Superflares happen when stars – for reasons that scientists still don’t understand- eject huge bursts of energy that can be seen from hundreds of light years away. In recent years, astronomers probing the edges of the Milky Way have observed very strong explosions on stars, which they’ve dubbed “ superflares,” that have energies up to 10,000 times that of typical solar flares.
