Total Solar Eclipse 2024: Google marks Surya Grahan with special animation

[ad_1] A total solar eclipse is slated to take place today when the Moon will pass between the Sun and Earth, completely blocking out the Sun's light. It will be a treat for skywatchers to witness one of the biggest celestial phenomena of 2024. The Sun will remain cloaked for four minutes, during which its enigmatic outer layer will be illuminated. While the solar eclipse won't be visible to people in India, a partial eclipse can be witnessed by those who live in Colombia, Spain, Venezuela, Ireland, Portal, Iceland, the United Kingdom, and some Caribbean countries. Ahead of this astronomical spectacle, Google curated a special animation. When users type the search term "solar eclipse" on Google, then they can see a graphic overlay depicting the phenomena: the moment when the moon pass...

Total Solar Eclipse will not be visible in India; Aditya L1 spacecraft will ‘miss it’- ISRO chief S. Somanath explains

[ad_1] Today, several parts of the world will witness the rare Solar Eclipse. While people in North America will be able to see the event, people in other countries could witness the live stream of the event on NASA TV, Google TV, and other platforms. The event is reported to stay for several hours, therefore, it is one of the biggest celestial events which you should not miss. However, ISRO's Aditya L1 spacecraft, which is actively monitoring the Sun, will miss the Total Solar Eclipse due to its location. Know what ISRO Chairman said in a statement.

Severe G4 Geomagnetic storm hits Earth! Solar storm could spark radio blackouts, auroral displays

[ad_1] In a recent alert from the National Oceanic and Atmospheric Administration (NOAA), Earth experienced a severe G4 geomagnetic storm on Sunday, indicating potential disruptions to radio communications. The NOAA emphasised that while the storm may fluctuate in intensity, ranging from lower levels to severe conditions, there's no need for panic among the public. However, staying informed about the storm's progression via NOAA's webpage is encouraged. The NOAA's alert notifies infrastructure operators to take mitigating actions against possible impacts, including increased voltage control problems and potential effects on satellite operations. The severity of the storm, hitting the G4 level on the NOAA's 5-point scale, arrived earlier than anticipated, reaching its threshold at 16:28 ...

NASA prepares for solar storm surge as new research unravels complexity of solar phenomena

[ad_1] In anticipation of an impending solar storm set to peak by 2025, NASA is intensifying its preparations to mitigate potential impacts on Earth. Recent predictions by the National Oceanic and Atmospheric Administration (NOAA) indicate a revised forecast for Solar Cycle 25, suggesting a stronger-than-expected peak between January and October of 2024.Solar cycles, recurring roughly every 11 years, mark fluctuations in the Sun's activity, notably evident through sunspots, areas where the magnetic field is exceptionally strong. With the upcoming peak, concerns are mounting regarding the potential consequences for our planet.

Solar storm alert! Sunspot AR3590 sparks aurora anticipation amid geomagnetic storm fears

[ad_1] In a celestial dance that has both scientists and skywatchers excited, the colossal Sunspot AR3590, which recently unleashed the most potent solar flare in over half a decade towards Earth, is now beginning to wane as it rotates to the far side of the Sun. Despite its current retreat, experts warn of a potential resurgence in two weeks, reigniting concerns about a geomagnetic storm. Although a scheduled Coronal Mass Ejection (CME) predicted to interact with Earth's magnetic field on March 2nd has yet to materialize, NOAA forecasters speculate that it might be belatedly en route, possibly impacting our planet on March 3rd.

Hyperactive Sunspot Unleashes Most Powerful Solar Flare in Six Years

[ad_1] A recent surge of solar activity has captured the attention of astronomers and space weather enthusiasts alike, as a hyperactive sunspot unleashed its third X-class solar flare within a 24-hour period. This remarkable series of events marks the most potent solar eruption in six years, raising concerns about potential impacts on Earth's space environment.The latest flare, labeled X6, emerged from sunspot AR3590, a colossal dark patch on the surface of the Sun that spans several times the size of Earth. This eruption, which occurred on February 22nd, follows two earlier X-class flares recorded on February 21st, each with magnitudes of X1.8 and X1.7, respectively. However, the X6.3 flare dwarfs its predecessors, showcasing the Sun's most intense outburst since 2017. The significance...

Brightest object in Universe found: It’s “500 trillion times more luminous than the Sun”, experts say

[ad_1] Astronomers and researchers have been studying the Universe for decades with the help of advanced telescopes and equipment around the world. Now, with the help of the European Southern Observatory's (ESO) Very Large Telescope (VLT), astronomers have located the brightest object in Universe. It is a quasar. Experts believe that this is the most luminous object ever found in deep space. And the brightness does not stem from something ordinary. The quasar is said to be energized by what is reported to be the fastest-growing black hole on record. Know more about the brightest object in the Universe here.Brightest object in the Universe ever foundAccording to a study published in Nature Astronomy, the brightest quasar was spotted by ESO's Very Large Telescope (VLT) and it is said to b...

Did other stars reshape Earth’s orbit? Check out these amazing stellar encounters

[ad_1] Astronomers have uncovered a celestial revelation: stars passing near our solar system have wielded a profound influence on the orbit of Earth as well as those of its its planetary companions. This cosmic dance, detailed in a study titled "Passing Stars as an Important Driver of Paleoclimate and the Solar System's Orbital Evolution" published in The Astrophysical Journal Letters, challenges our understanding of Earth's history and even encompasses shifts in climate.Stellar Perturbations and Climate VariabilityNathan A. Kaib, Senior Scientist at the Planetary Science Institute, leading the research with contributions from Sean Raymond at the Laboratoire d'Astrophysique de Bordeaux, highlights the significance of these stellar perturbations.

Solar storm! Sun unleashes massive X-class solar flare, triggers radio blackouts on February 9

[ad_1] There is no respite from solar storms for Earth. The Sun emitted a powerful X-class solar flare on February 9, reaching its peak at 8:10 a.m. (1310 GMT), resulting in shortwave radio blackouts across regions of South America, Africa, and the Southern Atlantic. Originating from sunspot AR3576, which had previously exhibited an M-class flare and plasma eruption on February 5, this recent solar flare marked a significant event in solar activity. Fortunately, by February 8, the sunspot had moved away as the sun and Earth rotated, thereby diverting the planet from the solar storm's direct trajectory. Coronal Mass Ejection and Solar ImpactAccompanying the solar flare was a coronal mass ejection (CME), characterized by a substantial release of plasma and magnetic field from the sun. Obs...

ISRO’s Aditya L-1 Mission: A paradigm of precision and fiscal wisdom

[ad_1] The Indian Space Research Organisation's (ISRO) Aditya L-1 mission has carved out a new chapter in the annals of space exploration, exemplifying innovation and cost-effectiveness. As India's first mission to study the Sun, it has redefined what is possible with meticulous planning and execution.ISRO embarked on a mission that was unprecedented in its history: placing a satellite in a halo orbit around the Lagrange Point 1 (L1)—a position in space devoid of any physical reference, navigated purely by mathematical calculations and software algorithms. This space point offers a stable platform for monitoring solar activities, and Aditya L-1's successful insertion here is a crowning achievement that speaks to ISRO's growing capabilities in space technology. The journey began on Septe...
