Sun unleashes jaw-dropping filament eruption — but Earth dodges the blast (photo)
A massive solar filament erupted today (May 7), producing a stunning display that spanned the sun's eastern limb and reached deep into the solar disk.
Filaments are cooler, dense ribbons of solar plasma that can hang suspended above the sun's surface by magnetic fields, according to NOAA. When these become unstable, they can erupt dramatically, sometimes launching coronal mass ejections (CMEs) into space — powerful blasts of solar plasma and magnetic fields that can trigger geomagnetic storms here on Earth. However, in today's eruption, the filament was oriented away from Earth, meaning it will have no direct impact on our planet.
"The sun is doing just enough to show that it still has what it takes to produce activity while also dodging Earth at all costs," space weather forecaster Sara Housseal wrote in a post on X.
The image was captured in remarkable detail by NOAA's GOES-19 spacecraft using its extreme ultraviolet (EUV) telescope called the Solar Ultraviolet Imager (SUVI) between around 6:30 a.m. EDT and 9:50 a.m. EDT (1030 and 1350 GMT). SUVI watched as the eruptive prominence showcased the sun's dynamic behavior in incredible detail.
Although this eruption won't affect Earth, forecasters are still keeping a close eye on solar activity this week. According to the UK Met Office, a combination of a weakening high-speed solar wind stream and possible glancing blows from previous CMEs could trigger auroras at high latitudes late Wednesday (May 7) or early Thursday (May 8), with another chance on Friday (May 9) when another high-speed solar wind stream is expected to strike.
Together, these space weather events could produce Minor Geomagnetic Storm (G1) conditions, meaning the aurora could become visible in northern parts of Canada, Alaska, Scandinavia, and other high-latitude regions.

BAE Systems delivers NOAA's SWFO-L1 and NASA's Carruthers Geocorona Observatory satellites for launch
The NASA and NOAA satellites will launch this fall from Kennedy Space Center in Florida to study and monitor space weather and its impacts on Earth BROOMFIELD, Colo., July 25, 2025 /PRNewswire/ -- BAE Systems (LON: BA) has successfully delivered two spacecraft in support of National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA) missions from its Boulder, Colorado campus to Kennedy Space Center in Florida. NASA's Carruthers Geocorona Observatory and NOAA's Space Weather Follow On – L1 (SWFO-L1) are scheduled to launch together this fall, providing scientists and forecasters with powerful new tools to increase our understanding of space weather and its impacts on Earth. BAE Systems designed and built both spacecraft and conducted extensive observatory-level testing to ensure they can withstand the harsh environment of space and safely operate at Lagrange point 1, an orbit approximately 1.5 million kilometers from Earth. "This new generation of satellites will extend our knowledge of the Sun and its impacts on Earth," said Bonnie Patterson, vice president and general manager of Civil Space for BAE Systems Space & Mission Systems. "The successful delivery of the SWFO-L1 and Carruthers Geocorona Observatory satellites marks a new era of discovery and space weather data that holds exciting promise, and we are proud to support these missions." Both the SWFO-L1 and Carruthers Geocorona Observatory were designed and built using BAE Systems' heritage Evolve spacecraft platform, which uses a common bus and standard payload interfaces to reduce cost and minimize delivery time. BAE Systems has trained the flight operations teams and will support mission operations. The SWFO-L1 observatory will track coronal mass ejections and measure solar wind. Through the collection and delivery of continuous observations, this mission will provide early warnings of potentially disruptive space weather events to protect infrastructure on Earth and in space. The Carruthers Geocorona Observatory mission will study the Sun's influence on the Earth's exosphere during both quiet solar periods and times of intense solar activity. Carruthers Geocorona Observatory is a collaboration with the University of Illinois, Urbana-Champaign, with Dr. Lara Waldrop serving as the mission's principal investigator; the University of California, Berkeley; and NASA's Goddard Space Flight Center. The SWFO-L1 mission is a collaboration with NOAA's National Environmental Satellite Data and Information Service (NESDIS) and NASA's Goddard Space Flight Center. SWFO-L1 and Carruthers Geocorona Observatory will launch alongside NASA's Interstellar Mapping and Acceleration Probe (IMAP). Through the delivery and launch of the satellites, BAE Systems continues its longstanding support of NASA's and NOAA's missions and goals. This includes work for NASA on the Hubble Space Telescope, Chandra X-ray Observatory, James Webb Space Telescope and the Nancy Grace Roman Space Telescope, among others. Support of NOAA weather science missions include work on the NOAA-20 and NOAA-21 satellites, the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite, and the upcoming Space Weather Next L1 Series satellite.

'Disabling' Chronic Illness in Children Not Taken Seriously: Experts
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A new study by Rutgers University has highlighted that a significant number of young children are experiencing ongoing symptoms after COVID-19 infection, signifying that greater research needs to be poured into evaluating the risk and treatment of long COVID in children. The study, released on July 23, coincides with Pediatric Long COVID Awareness Week, running from July 21 to 25, run by the advocacy group Long Covid Families. Over the course of the week, the group has been bringing together families, clinicians, researchers, and advocates to raise more awareness on the wide-reaching impact of long COVID in children. "This is a public health crisis for children. And it demands action," Long Covid Families said in its promotion of the condition's awareness week. "Because people operate under the false assumption that if you are young and healthy, like kids, COVID is an inconsequential nothingburger and we should not worry about it," Dr Ziyad Al-Aly, a professor of medicine at Washington University in St. Louis, told Newsweek. "Of course, this is not accurate at all," he added. Long COVID in children "always demanded more attention and seriousness." File photo: a young girl is unwell lying in bed with a teddy bear. File photo: a young girl is unwell lying in bed with a teddy The Study Found The study assessed 1,011 children, of whom 472 were aged 2 or younger, and 539 were aged between 3 and 15. It was found that 101, or 15 percent, of the 677 children who had previously tested positive for SARS-CoV-2 infection were identified as likely having long COVID. Long COVID is recognized as symptoms and health complications following COVID infection that persist for several weeks or months after the initial infection. It can result in a wide range of symptoms, affecting multiple systems in the body. Co-author of the study, Lawrence Kleinman, who is also chair of the Department of Pediatrics at Rutgers University, told Newsweek that he was not "surprised by these findings and would not be surprised to learn in the future that they understate the prevalence of long COVID." Previous studies estimated the prevalence of long COVID in children to be between 10 and 20 percent—suggesting it has become one of the most common chronic illnesses in children. Asthma, often described as the most common chronic illness in children, affects 16 percent. "Our methods were designed to be conservative, that is to maximize the likelihood that we distinguished long COVID from other causes," Kleinman said. "That means that our estimates are likely to be lower than the actual rate of long COVID." "At the beginning of the pandemic, no one knew that long COVID existed," he added. The first reports from China included" inaccurate reports" that children were spared COVID, he said, adding that the reports "grew into a myth which in turn created a mindset that COVID in kids didn't matter." As a result, there "was a misconception that children could not get COVID - but we know that's not true," Melissa Stockwell, another author of the study and chief of the Division of Child and Adolescent Health at Columbia University, told Newsweek. "We are still very behind in raising awareness about long COVID in children," she added. Another reason why long COVID was not taken seriously in children is that "the symptoms associated with long COVID in children were not properly defined," Dr. Akiko Iwasaki, director of the Center for Infection and Immunity at the Yale School of Medicine, told Newsweek. She added that the study underscored "the need for the society to take long COVID in children seriously." However, Dr. Gerald Teague, a professor of pediatrics at the University of Virginia School of Medicine, told Newsweek that the study's investigators "did not confirm COVID infection with diagnostic tests nor did they measure antibodies to COVID in the participants," which would have provided a more accurate screening of the condition. He also noted that children not flagged as having COVID in the study may have had "asymptomatic infection." Although, despite some concerns, he said, with the study, that it was a "proof of concept that long COVID may be a bigger problem than we thought." The Impact Of Long COVID On Children "There is great concern for the younger generation, both about the long-term impacts of the pandemic itself, but also for those with Long Covid," Stockwell said. Long COVID in children can manifest in a number of different symptoms, ranging from "annoying to disabling," Kleinman said. The chronic illness can cause "pain, distress, or disability" in children, directly impacting the child's interaction with their family and friends, and may "hurt school performance, athletic performance, or even the capacity of children to conduct normally routine activities," he added. These factors are of great concern, Al-Aly said, as "we worry about kids' educational attainment, forming friendships, sports, and others, and all of these facets of normal development could be impaired in long COVID." "This may negatively affect kids in their most formative years—leaving them scarred for a lifetime," he added. Long COVID can leave some children bedbound for years, Iwasaki said. "If you have ever spoken to a parent of a child with long COVID, you quickly learn how devastating it can be to the lives of the children and their family," she added. What Experts Think Should Be Done One key part of tackling the issue is down to "improving vaccine uptake," Al-Aly said. However, the Trump administration has recently removed COVID vaccines from the Centers for Disease Control and Prevention (CDC) recommendation for healthy children and pregnant women, as part of Health Secretary Robert F. Kennedy Jr's "Make America Healthy Again" (MAHA) campaign. Kennedy Jr, a well-known vaccine sceptic, said, when announcing the update on X: "It's common sense and it's good science." Another important step is increasing understanding, Stockwell said. "We really need pediatricians to understand what long COVID looks like in children and understand that symptoms are actually different in different-aged children as well," she added. Treatments are the next vital step, Kleinman said. "We need to develop and identify effective treatments for long COVID in a rapidly iterative and long-term approach to quickly identify promising treatments and to evaluate their effectiveness and safety in practice." That treatment, though, needs to "get at the root causes of the disease," Iwasaki said. She added that long COVID is a disease "driven by the virus and the host responses to the virus involving the immune, neurological, cardiovascular, gastrointestinal and pulmonary systems." From a policy perspective, "flexible attendance at school, proper training of teachers and pediatricians, insurance coverage and more funding for research" would all help tackle the issue, Iwasaki added. More broadly, supporting children with long COVID and preventing further cases will require "investment in health and health care services, physical and occupational rehabilitation, and mental health services," Kleinman added, saying this "will be critical for the population health of our children for the foreseeable future."

Next-Gen Breakthroughs Transform Influenza Diagnostics
Influenza diagnostics refers to methods and devices that are used to detect influenza virus infections in individuals, including rapid antigen tests, molecular assays (such as RT-PCR), and immunoassays. The market for influenza diagnostics is increasing due to increasing global awareness about infectious diseases, increasing incidence of influenza and increasing outbreaks, increasing demand for rapid and accurate testing, increasing demand for progress in clinical technologies and further emphasis on the identity of initial diseases and the identity of early diseases by governments and healthcare organizations. Key Growth Drivers and Opportunities Global Awareness about Infectious Diseases: Global awareness about infectious diseases increases the demand for increasing, accurate, accurate and comprehensive testing. Recent experiences with epidemic such as public health campaigns, media coverage, and Covid-19 have increased the importance of the general population of viral transmission and timely diagnosis. As a result, the healthcare provider and the government are prioritizing investment in clinical infrastructure, rapid testing development and monitoring systems to prevent large -scale outbreaks. This awareness leads to maximum adoption of influenza diagnostic tools in hospitals, clinics, airports and even home settings, which promotes continuous market growth. Challenges Influenza diagnostics faces the high cost of advanced testing technologies in the market, low income and clinical equipment limited to clinical equipment in rural areas and the limits of variability in test accuracy-especially with antigen tests that may be false negative. Additionally, the seasonal nature of influenza may demand ups and downs, affecting continuous revenue creation and investment. Regulatory obstacles and skilled personnel need to be widely adopted to adopt molecular diagnosis. Innovation and Expansion Quest Diagnostics Gets CDC Contracts to Create Oropouche Virus and H5 Avian Flu Tests In October 2024, leading diagnostic information services provider Quest Diagnostics announced that the U.S. Centers for Disease Control and Prevention (CDC) has awarded it multiple contracts to support testing and ongoing laboratory readiness for two newly discovered infectious diseases in the Americas. By guaranteeing that a national commercial laboratory provider may promptly augment public health laboratories in the case of an infectious disease epidemic in humans, the agreements will enhance the country's readiness for avian influenza and Oropouche viruses. The FDA Approves the First Over-the-Counter Flu and COVID-19 Test at Home In February 2023, the first over-the-counter (OTC) at-home diagnostic test that can distinguish and identify influenza A and B, sometimes referred to as the flu, and SARS-CoV-2, the virus that causes COVID-19, was granted an emergency use authorization (EUA) by the U.S. Food and Drug Administration. A single-use at-home test kit, the Lucira COVID-19 & Flu Home Test yields findings from self-collected nose swab samples in around half an hour. A single-use test for those exhibiting symptoms and indicators typical of a respiratory tract infection, including COVID-19, is the Lucira COVID-19 & Flu Home Test. The test is available without a prescription and may be done entirely at home with nose swab samples that people 14 years of age or older self-collect. Inventive Sparks, Expanding Markets Investing in major development strategies for influenza diagnostics manufacturers, investing rapidly and in multiplex test technologies, expanding at home and point-of-care test offerings, forming partnership with healthcare providers and governments, securing regulatory approval quickly and strengthening the global distribution network-in special emergence markets.
