Solar orbiter reveals plasma jets as potential source of Solar Wind

[ad_1] The ESA/NASA Solar Orbiter has uncovered a series of brief material jets emerging from the sun's outer layer, each lasting 20 to 100 seconds and expelling plasma at 100 km/s. These jets hold the potential to be the elusive source of the solar wind. The solar wind, a stream of charged particles, continuously escapes the sun and interacts with celestial bodies. Upon colliding with Earth's magnetic field, it produces auroras. Understanding the solar wind's origin near the sun has been a longstanding challenge. However, the Solar Orbiter's advanced instruments have made significant progress. Data from the spacecraft's Extreme Ultraviolet Imager (EUI) reveals faint, transient features at the sun's south pole associated with small plasma jets. Lakshmi Pradeep Chitta from the Max Plan...

Shocking! CME with SEVERE solar storm potential hits Solar Orbiter satellite at 1500 km per second

[ad_1] After the Earth was struck by two different coronal mass ejection (CME) clouds in successive days, many believed this was the end of the Sun's assault during the week at hand. But another event has shocked the astronomy community. On July 26, a farside flare eruption released an extremely powerful CME and it hit the European Space Agency (ESA) operated Solar Orbiter satellite. Luckily, the CME cloud delivered a glancing blow as it was moving in a different direction, but if it was Earth-directed it could have sparked a severe solar storm event owing to its incredible intensity.According to a report by SpaceWeather.com, “Two days ago, a bright CME rocketed away from the farside of the sun. Its plane-of-sky speed in SOHO coronagraph images exceeded 1,500 km/s. If this CME had hit E...

Astonishing! ESA Solar Orbiter captures stunning visuals of the Sun

[ad_1] The European Space Agency’s space laboratory has captured the Sun in stunning detail. The Sun has been an object of scientific interest for hundreds of years with the first observations of the Sun dating back to 2300 B.C. by Chinese astronomers. However, with the advancement of technology, it has become relatively easy to collect and study data about this bright star at the center of our solar system. The European Space Agency had sent a complex space laboratory called the Solar Orbiter with a mission to capture close-up images of the Sun and collect important data which could help unravel the mysteries of this highly luminous object.The Solar Orbiter has captured extremely detailed stunning visuals of the Sun. The space laboratory made its latest close approach to the Sun on O...

Sun’s solar switchback mystery solved, courtesy this tech marvel

[ad_1] European Solar Orbiter, has unveiled the mystery of the origin of a solar switchback. The European Solar Orbiter, has solved the mystery of the origin of a magnetic phenomenon called a solar switchback i.e, sudden and large deflections of the solar wind's magnetic field. The findings reveal their physical formation mechanism that might help accelerate the solar wind. The spacecraft provides a full view of the structure, which appears to have an S-shaped character as predicted in the past.The data provided by the orbiter suggest that the rapidly changing magnetic fields can have their origin near the surface of the Sun. The sudden change in the magnetic field around the Sun was first observed in the 1970s by the German-...

ALERT! ESA Solar Orbiter spacecraft HIT by Coronal Mass Ejection from the Sun

[ad_1] ESA’s Solar Orbiter was hit by a recent Coronal Mass Ejection which erupted from the surface of the Sun. Here’s what ESA said regarding the incident. Coronal Mass Ejections (CMEs) have been a frequent occurrence these past few days with nearly 32 CMEs erupting from the surface of the Sun in the last week alone. Our Sun is nearing its peak in its 11-year solar cycle which has resulted in increasing solar activity these past few months. As the Sun enters the peak of the solar cycle around 2025, solar activity is expected to further increase substantially.A recent CME which erupted from the surface of the Sun hit the European Space Agency's (ESA) Solar Orbiter which flew by Venus for a gravity-assist manoeuvre in the earl...
