Earth to be hit as Sun erupts with most powerful explosion of 2025
A powerful coronal mass ejection (CME) is heading straight for Earth, with both NASA and NOAA models in rare agreement that the solar storm will strike our planet on June 1.The impact is expected to spark a severe (G4-class) geomagnetic storm, raising the possibility of dazzling auroras visible across much of Europe and numerous US. states — potentially making it one of the most significant space weather events of Solar Cycle 25 if the storm reaches its predicted intensity.advertisementThe source of this solar eruption is sunspot 4100, which erupted in dramatic fashion on May 31.
Earth-orbiting satellites detected an M8.2-class solar flare that lasted more than three hours, an unusually long and powerful event. While technically just shy of the X-class threshold, the flare's slow, sustained energy release provided ample force to launch a massive CME from the Sun's atmosphere.Shortly after the flare, SOHO coronagraphs recorded a bright, fast-moving halo CME barreling directly toward Earth.Type II radio emissions from shock waves within the eruption indicate a velocity of about 1,938 kmps — among the fastest recorded this cycle. The CME's arrival is anticipated between midday and early evening on June 1, though exact timing remains uncertain due to fluctuating solar wind conditions.Upon impact, the CME is expected to trigger immediate geomagnetic disturbances, with G4-class storm conditions possible through June 2. The storm's severity will depend on the orientation and strength of the CME's magnetic field as it interacts with Earth's magnetosphere.advertisementIf conditions align, auroras could be visible at unusually low latitudes, offering a rare spectacle for skywatchers well beyond the polar regions.While this event is not expected to rival the legendary May 2024 storm, it could still be one of the most powerful of the current solar cycle.In addition to auroras, severe geomagnetic storms can disrupt power grids, satellite operations, and GPS systems, prompting infrastructure operators to remain on alert.As the world watches the skies, scientists and space weather forecasters emphasize that each event like this provides critical data for understanding and preparing for the Sun's unpredictable moods.

Northern lights set to shine over Canada tonight; Millions could witness rare solar storm display
A powerful solar storm is set to light up the skies over Canada on Monday night(June 2), offering a rare opportunity for millions to witness the mesmerizing aurora borealis . Cities where you can watch the northern lights tonight The US National Oceanic and Atmospheric Administration ( NOAA ) has forecasted that the northern lights will be visible directly overhead across nearly all of British Columbia, Alberta, Saskatchewan, Manitoba, Yukon , and the Northwest Territories, including cities like Victoria, Vancouver, Calgary, Edmonton, Regina, Saskatoon, Winnipeg, Yellowknife, and Whitehorse. Large parts of Ontario, Quebec, and Atlantic Canada may also catch a glimpse of the lights overhead or on the northern horizon. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Access all TV channels anywhere, anytime Techno Mag Undo Timings and conditions The celestial display is expected to peak overnight between 11 p.m. and 2 a.m. EDT. However, viewing conditions will depend on clear and dark skies, away from city lights. In areas near the southern edge of the aurora's visibility, such as parts of Newfoundland, Nova Scotia, and southwestern Ontario, an unobstructed view of the northern horizon will be essential. This heightened aurora activity is due to a coronal mass ejection (CME) that occurred on May 31, originating from the highly active sunspot region AR4100. Live Events The CME reached Earth on June 1, leading to a G4-class geomagnetic storm, one of the more severe classifications. Such storms can cause disruptions in satellite operations, communication systems, and power grids, but they also produce spectacular auroras, with the northern lights potentially visible at lower latitudes than usual. While the northern lights are typically confined to regions like Alaska and Northern Canada, stronger solar activity in recent years has extended visibility farther south. In 2024, the lights were visible as far south as Texas, a rare occurrence. Although the current forecast does not confirm if Texas is included this year, past events raise the possibility that the state could again witness the aurora. Places away from city lights are ideal For those hoping to catch a glimpse of this natural wonder, it's advisable to find a location away from city lights with a clear view of the northern horizon. Even in areas where the lights could be visible directly overhead, avoiding light pollution and having clear conditions will provide the best viewing experience. The northern lights will also be visible on Tuesday night(June 3), but with a more limited range. As always, the best viewing conditions depend on clear, dark skies and minimal light pollution.

Rare gas detected on distant exoplanet sheds light on planet formation: study
Sydney, June 2 (UNI) Astronomers have detected silicon monoxide gas in the atmosphere of a planet 850 lightyears from Earth, the first time the gas has ever been observed on any planet, including those in the solar system. According to a press release from the University of Newcastle in Australia on Monday, the research offers unprecedented insight into the formation and atmospheric chemistry of exoplanet WASP-121b, also known as Tylos. The planet, discovered in 2015, is an ultra-hot gas giant similar in size to Jupiter but far hotter, with temperatures exceeding 2,500 degrees Celsius, the release said. The international team, led by Tom Evans-Soma from the University of Newcastle and involved 18 institutions across Australia, Germany, the United States, Britain and India, used NASA's James Webb Space Telescope to observe Tylos continuously for 40 hours, which is the most comprehensive observation ever made of an exoplanet completing a full orbit, it said. Over 3,500 exposures, about one every minute, were captured, allowing researchers to analyze both the dayside and nightside atmospheres, said the study published in Nature Astronomy. While expected molecules like water vapor and carbon monoxide were found, the surprising detection of silicon monoxide and methane, rare on such hot planets, challenges existing atmospheric models, Evans-Soma said. The study suggests Tylos formed in a cold, distant region rich in ice and rocky material before migrating closer to its star, where intense heat vaporized the rocks into silicon monoxide, a planet born in ice and forged in fire, he said. Though Tylos is uninhabitable, the study advances the search for Earth-like planets by improving techniques to detect potential signs of life in distant atmospheres, he added. UNI XINDUA AKT SSP

India's First Gaganyatri To Taste Moong Dal Halwa, Rajma Chawal In Space
The Axiom-4 mission is scheduled for launch on June 8 at 6:41 pm (IST), aboard a SpaceX Falcon 9 rocket with the Crew Dragon capsule. The mission will last approximately 14 days, with splashdown expected around June 22. The crew includes Group Captain Shubhanshu Shukla (India) - Mission Pilot, Peggy Whitson (USA) - Mission Commander, Slawosz Uznanski-Wisniewski (Poland), and Tibor Kapu (Hungary). The Ax-4 crew completed eight months of intensive training at NASA's Johnson Space Center in Houston, including simulations, emergency protocols, and microgravity adaptation. Group Captain Shukla also trained in Russia and India prior to this, and his preparedness has been praised by Dr V Narayanan, Chairman, ISRO. ISRO has selected seven microgravity experiments for Ax-4, spanning agriculture, food, and human biology. Highlights include microalgae radiation impact, sprouting salad seeds in space, tardigrade survival and transcriptomics, and muscle regeneration under microgravity. These experiments are designed by Indian institutions and mark a significant step in India's space biology research. In a cultural first, Group Captain Shukla will carry moong dal halwa, rice, and mango 'nectar', rajma-chawal, and Jaipuri mixed vegetables to the ISS. This echoes the culinary legacy of astronaut Sunita Williams, who had fish curry and samosas during her missions. This mission is a joint effort by ISRO, NASA, and Axiom Space, with India reportedly investing $60-70 million for the seat, or about Rs 550 crore. It is also a diplomatic milestone, with decisions coordinated at the PMO level. The mission also strengthens India's ties with the European Space Agency (ESA). ESA astronaut Slawosz Uznanski-Wisniewski will fly alongside Group Captain Shukla, and both agencies are exploring future collaborations, including India's proposed Bharatiya Antariksh Station (BAS). Ax-4 is a precursor to India's indigenous human spaceflight program, Gaganyaan, targeted for late 2026. The mission will provide Group Captain Shukla with critical hands-on experience in orbital operations, teamwork, and emergency preparedness skills vital for Gaganyaan's success. Dr V Narayanan, Chairman, ISRO, shared insights into the mission and the Gaganyaan program during an interview with Pallava Bagla. "Right now, we are working on our Indian Gaganyaan program. For this, we have already selected four astronauts. They have undergone a set of training, both theoretical training and experimental training," he said. "Now we have the opportunity to send one of the astronauts to ISS. And this will bring a lot of expertise, knowledge, advantage, working with the other astronauts, carrying out a couple of experiments," Dr Narayanan added. "That is why Prime Minister Narendra Modi approved that entire program. Right now, the training part is going on at NASA." On being asked, as ISRO Chairman, if he's happy with Group Captain Shukla's performance, if he will make a good astronaut to the International Space Station, and if he must learn newer things that will come in handy in Gaganyaan, Dr Narayanan responded, "I am extremely happy. ISRO is a teamwork. Our Gaganyaatri is doing extremely well, that is what is my understanding is. These are all exceptional people with great devotion and single-minded devotion." With the SpaceX Falcon 9 Crew Dragon with astronaut Sunita Williams and Butch Wilmore executing a great mission, does that make them confident that Axiom 4 mission with the same rocket type and crew module would also do well? Dr Narayanan replied, "To be frank, I consider myself a born optimist. And when we are working in this type of space program, you know, we always believe that this will be a successful program. And I am having full confidence that things will go well because this experience will also help handle the situation. It will be a very-very fantastic mission." "Because one of the Gaganyatri is going, he understands physically, of course, a lot of training is there. But then this is a hands-on experience going with other astronauts and then getting the direct experience and trying to work with them as a teamwork," he explained. Asked about the progress of the Gaganyaan program, he said there is a series of tests that need to be done. On when to expect the first uncrewed flight and the first human flight, Dr Narayanan elaborated, "For Gaganyaan program, we must develop major systems. One is a human rating of the launch vehicle... improving the reliability, enhancing the redundancy aspect wherever possible and required... I will say 90% work is completed." "We are targeting 2026-end. That's the commitment we have given to the government. But we are working in accelerated mode," he added. Dr Narayanan also agreed when asked if safe landing is the most important thing. "This is the first time a human interface is involved. The life, precise life of our own citizen is the key there. And we cannot have any compromise on that." "The key is the successful mission. That is the key. So, towards that, we are all working," he concluded. This mission marks a significant milestone in India's space exploration journey, showcasing the nation's growing capabilities and international collaborations. As Group Captain Shubhanshu Shukla prepares for his journey to the ISS, the world watches with anticipation, eager to witness India's leap into private spaceflight and the promising future of the Gaganyaan program.
