From sparking powerful solar storms to causing forest fires, know the dangers of solar winds

[ad_1] Solar winds have been part of the reason behind the recent series of solar storms that have struck the Earth in the last couple of weeks. They either sparked solar storm incidents or amplified an active storm. But often, we tend to overlook its potential to cause damage when compared to solar flares and coronal mass ejections (CME). However, as per NASA officials and research papers, these stellar winds are capable of not only sparking solar storms but also triggering forest fires, and damaging spacecraft, potentially putting the lives of astronauts in danger.What are solar winds?Solar winds are not winds since space is entirely vacuum and air does not exist there. These ‘winds' are powerful waves of plasma that are created in the corona of the Sun. They contain both solar partic...

Aditya-L1 mission set to unlock solar mysteries as it approaches target position

[ad_1] India's space agency, ISRO, is making significant strides with its Aditya-L1 mission, aimed at advancing our understanding of the Sun. Equipped with seven cutting-edge instruments, the spacecraft is not only observing the Sun from a distance but also measuring high-energy particles emitted as it travels. This data is crucial for monitoring space weather and gaining insights into dynamic solar processes, still shrouded in mystery.The Chromosphere ConundrumA key focus of the mission is to unravel the Sun's enigmatic heating process, from the chromosphere to the corona. Recent research suggests that fine structures on the chromosphere hold the answers to why the outer atmosphere is hotter than the surface, akin to a campfire getting hotter as one moves away from it. We are now on Wh...

What is Aditya-L1 mission’s HEL1OS? ISRO explains

[ad_1] In a remarkable milestone for India's space exploration efforts, the Aditya-L1 mission, the nation's maiden solar observation mission, set its course for the Sun-Earth L1 point (L1) on September 2. On Tuesday, the Indian Space Research Organisation (ISRO) unveiled the success of the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) payload, which recorded the impulsive phase of solar flares during its inaugural observation period on October 29.What is Aditya-L1 mission HEL1OSHEL1OS, an innovative hard X-ray spectrometer, is part of the Aditya-L1 mission designed to study the Sun's activities and notably, it is capable of capturing the early impulsive phases of solar events. This instrument operates within the wide X-ray energy band of 10- 150 keV, presenting a revolutionary app...

Aditya-L1 mission update: First high-energy X-ray of solar flares captured by ISRO spacecraft!

[ad_1] Aditya-L1 mission spacecraft is now in its trajectory towards a point where the Sun-Earth system is at equilibrium to study various phenomena. In a recent update, the Aditya-L1 spacecraft has captured the first-ever high-energy X-ray of solar flares during its monitoring phase. Till now, the spacecraft has made successful manoeuvres including a Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre and now it will be placed at the halo orbit of Lagrange Point 1. Know what ISRO uncovered with the X-ray image of the Sun.Aditya-L1 mission findingsISRO shared an update about the Aditya-L1 mission through their official X (Formerly Twitter) handle saying that the HEL1OS spectrometer captured the first high-energy X-ray of solar flares along with GOES X-ray light curves.

Solar flares, blackouts, to solar storms: Know how space weather has affected Earth in the last 24 hours

[ad_1] The last 24 hours have been quite a ride for Earth, owing to the Sun nearing the peak of its solar cycle. On November 2, two M-class solar flares erupted on the Earth-facing side of the Sun. Both the flares released extreme ultraviolet radiation directed towards our planet that sparked short-wave radio blackouts. The effects of these blackouts were seen in the American and African continent. Additionally, reports have confirmed that two separate coronal mass ejections (CME) will strike the Earth tomorrow, November 4, and can trigger a minor solar storm.Solar storm can strike tomorrowAccording to a report by SpaceWeather.com, “One and perhaps two CMEs could graze Earth's magnetic field on Nov. 4th. Individually, neither CME is particularly significant, but together they could spar...

Aditya-L1 mission: Massive data coming, here is how ISRO is preparing for it

[ad_1] The Aditya L-1 mission spacecraft is well on its way to the L-1 point from where it will constantly watch the Sun. ISRO expects it to generate massive amounts of data and for that, it will require huge manpower. The Indian Institute of Technology Kanpur (IITK) recently hosted the fifth Aditya-L1 Mission workshop in collaboration with the Aryabhatta Observational Science Research Institute (ARIES), Nainital. This three-day workshop was organised by the Department of Physics at IIT Kanpur and the Aditya-L1 Support Cell. These efforts are expected to yield great results derived from the information provided by Aditya L-1.Bridging Theory and PracticeThe Aditya-L1 Mission, undertaken by ISRO, marks India's inaugural journey to study the Sun, its atmosphere, and its influence on Earth....

Solar flare eruptions likely soon, but solar storms not seen hitting Earth over the weekend

[ad_1] This weekend promises a stark contrast to the geomagnetic fireworks we witnessed last week. Unlike the previous weekend, there are no looming Coronal Mass Ejections (CMEs) threatening Earth's magnetic field. Our planet's magnetosphere is expected to remain serene and undisturbed from any solar storm.According to a report by spaceweather.com, forecasters at the National Oceanic and Atmospheric Administration (NOAA) have revealed details of the sunspot AR3451, a newcomer on the solar stage, which has suddenly sprung to life. It has rapidly grown over the past 24 hours, boasting more than a dozen dark cores, two of which are larger than Earth itself. While magnetic observations of this sunspot are not conclusive due to its orientation away from Earth, it seems to possess a complex '...

Solar storm warning: NASA’s Mars rover snaps Sun turning, spies dangerous sunspot facing Earth

[ad_1] In an intriguing celestial observation, NASA's Perseverance Rover on Mars has captured a striking view of a massive sunspot, signalling a region of heightened solar solar activity on the far side of the Sun. This sunspot is rotating to face the Earth and the likelihood of a solar storm has just increased manifold.Early Solar WarningAccording to a blog post on spaceweather.com, the unique positioning of Mars on the opposite side of the sun allows Perseverance to provide advanced notice of approaching sunspots, sometimes more than a week before they become visible from our planet. This early alert has been issued: A significant sunspot has been seen and a solar storm could be enroute.
