Scientists Warn of Impending Solar Storm After Recent Sun Eruptions

Scientists have issued a warning about a potent solar storm expected to strike Earth this week following powerful eruptions from the Sun. With a 60 percent chance of impact on Tuesday, the storm could cause geomagnetic disruptions and pose risks to power grids and astronauts in space. Despite concerns, no major disruptions have been reported so far. Recent eruptions from the Sun have raised concerns among scientists about the potential impact of an upcoming solar storm on Earth. The National Oceanic and Atmospheric Administration (NOAA) has issued a warning, indicating a 60 percent likelihood of the solar storm hitting Earth on Tuesday, with a lower possibility on Wednesday. The X handle of NASA Sun and Space also confirmed the occurrence of a M6.6-class solar flare on May 13, although ...

FU Orionis Star System’s Violent Eruptions Explained After Decades of Speculation

Breaking News, Space

In the serene expanse of the Milky Way, most stars go about their business quietly, but one star refuses to conform to the norm. Enter FU Orionis, a binary system that has been erupting dramatically since 1936, puzzling astronomers with its erratic behavior. Now, after 88 years of speculation, a breakthrough has been made. Astronomers, led by Antonio Hales of the National Radio Astronomy Observatory, have finally uncovered the secret behind FU Orionis' relentless outbursts. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA), they have directly imaged a stream of material being devoured by the star – a crucial piece of the puzzle that has eluded scientists for decades. "This discovery provides the first direct observational evidence of the material fueling...

NASA Explains Phenomenon Behind Spectacular Auroras Illuminating Earth’s Skies

Breaking News, Climate Actions, Environment, Space

Auroras, the mesmerizing celestial light shows, have once again graced the skies across several regions, captivating spectators with their vibrant hues of pink, green, and purple. This dazzling display, commonly known as the "northern lights," is a result of a powerful solar storm that has swept across the planet. The phenomenon, triggered by eruptions on the Sun, has been elucidated by the National Aeronautics and Space Administration (NASA) in a recent thread on X (formerly Twitter), shedding light on the intricate interplay between solar activity and Earth's atmosphere. According to NASA, solar eruptions manifest in two primary forms: solar flares and coronal mass ejections (CMEs). Solar flares, intense bursts of light, occur when the Sun's magnetic fields undergo abrupt rearrange...

Discovery of Atmospheric Richness on Exoplanet Janssen

Breaking News, Environment, Space

For the first time, astronomers have uncovered evidence of a substantial atmosphere surrounding a rocky world beyond our Solar System. Although not suitable for human habitation, this remarkable finding marks a significant advancement in planetary astronomy and our understanding of exoplanetary diversity. The world in question, known as Janssen or 55 Cancri E, is classified as a super-Earth exoplanet. Situated in close proximity to its host star, Janssen's surface is believed to be engulfed in a vast ocean of molten lava, rendering it inhospitable to life as we know it. Janssen orbits a star named Copernicus, or 55 Cancri A, one of the binary pair of dwarf stars located approximately 41 light-years away from Earth. Since its discovery in 2004, astronomers have been captivated by the ...

Earth Braces for Impact as Sun Unleashes Consecutive Flare To Threatening Technological Infrastructure

Breaking News, Disasters, Space

In a dramatic display of solar activity, the Sun has unleashed a series of powerful flares, posing potential risks to Earth's technological infrastructure and space exploration efforts. The recent surge in solar eruptions, occurring on consecutive days, has heightened concerns among scientists and space agencies worldwide. The first flare, categorized as an X-class flare, the most intense classification, occurred on May 2, originating from sunspot region AR3663. This eruption, lasting approximately 25 minutes, resulted in shortwave radio blackouts across regions including Australia, Japan, and parts of China. Solar physicist Keith Strong described it as an "impulsive flare," indicative of its sudden and intense nature. Barely a day later, on May 3, another significant eruption was ob...

Solar Flare Triggers Radio Blackouts Across Pacific Region

Breaking News, Disasters, Space

A recent powerful solar flare originating from sunspot region AR3654 caused widespread radio blackouts across the Pacific region. The eruption, which lasted for 12 minutes on April 30, released near X-class solar flares, the most potent type. Solar flares are associated with sunspots, where magnetic fields are strongest. According to NASA, solar flares occur when powerful magnetic fields in and around the Sun reconnect, releasing magnetic energy that builds up in the solar atmosphere. These flares are classified based on their strength, with X-class flares being the most powerful, followed by M-class, C-class, and B-class flares. The April 30 flare, measuring M9.53, was just below an X-class solar flare, ionizing the upper atmosphere upon hitting Earth. Mariners and ham radio operato...
