Last weekend, the NASA Solar and Heliospheric Observatory (SOHO) satellite detected that a massive sunspot lurked on the farside of the Sun which was big enough to change the way the Sun vibrates. On its way to turning and facing the Earth, it exploded on Tuesday and released a nearly X-class solar flare that sparked radio blackouts in North America. Now, the gigantic sunspot is finally facing the Earth and researchers are concerned about the possibility of yet another major solar storm spell.As per a SpaceWeather.com…

After a relatively low period of solar activity, the Sun sprung back into action yesterday, May 16. A near-X-class solar flare eruption occurred on the southeastern limb of the Sun. Even as the explosion was on the horizon of the Sun and a part of it was eclipsed due to its edge, the solar flare had a major impact on the Earth. Ultraviolet radiation ionized the upper atmosphere and caused a shortwave radio blackout over North America and the northern parts of South America. And now, fears are rising over another major…

After days of warnings for a G3-class geomagnetic storm, yesterday the coronal mass ejection (CME) finally hit the Earth and it turned out to be a dud. The impact only sparked minor G1-class storms briefly before being dispersed by the planet's magnetosphere. While the Earth was lucky in this encounter, soon a far bigger problem is coming its way. Researchers have spotted a huge sunspot group on the farside of the Sun and it is big enough to change the way the Sun vibrates. It is expected to face our planet the next week…

Yesterday, we were discussing the possibility of a solar storm this week as a result of a solar flare eruption on the sunspot AR3288. The early projections revealed that not enough coronal mass ejection (CME) had been released to spark a solar storm on Earth. However, something interesting happened. With the sunspot being in a constant state of instability, multiple flares occurred, all of which released faint CMEs, not capable of causing a solar storm by themselves. However, some of them have merged together to form a…

On April 30, the forecasters from the National Oceanic and Atmospheric Administration (NOAA) warned about a sunspot, named AR3288, which was growing at an exponential rate and contained unstable delta-class magnetic fields. Just a day after the warning, the sunspot exploded, blasting a powerful solar flare in the direction of the Earth. As per NASA, it was an M7-class flare eruption and it sparked a radio blackout over the Atlantic Ocean region. The bigger question now is whether a solar storm is coming for the Earth.A…

In just a few hours, the Earth is expected to witness a G1-class geomagnetic storm. This minor storm will be triggered by a coronal mass ejection (CME) cloud which is going to deliver glancing blows to the Earth. The storm is not expected to be intense. And one of the reasons behind that is the CME cloud is not a cannibal CME. This particular subtype of CME is considered one of the most dangerous solar phenomena when it comes to triggering solar storms. Recently, the NASA Solar and Heliospheric Observatory (SOHO)…

It has been just over 24 hours since the severe solar storm struck Earth, but looking at things today, there appears to be no relief for our planet. Forecasters have predicted that another coronal mass ejection (CME) cloud is expected to strike the Earth tomorrow, April 27, sparking a geomagnetic storm. Another major storm just days later could lead to a series of radio blackouts, GPS disruptions, and more. As scientists continue to assess the full impact of the previous G4-class geomagnetic storm, this one can add to…

A terrifying X-class solar flare has erupted on the Sun in the early hours today, March 29. The solar flare eruption occurred on the Earth-facing sunspot AR3256 and has caused strong shortwave radio blackouts in large regions of Australia, southeast Asia and New Zealand. This came after it was reported yesterday that as many as 9 sunspot groups have appeared on the Earth-facing side of the Sun. Forecasters had claimed that the sunspots seemed to be stable, but one of them unexpectedly exploded.The incident was reported…

Last month, NASA made a remarkable discovery when it recorded the sound coming from RS Puppis, a Cepheid variable star which is located about 6,500 light-years away. But that's not all the sound we can hear from space. Our own star, The Sun, also makes a really eerie sound that is so loud it could even deafen everyone on Earth. This would happen if sound could propagate through space. But because it doesn't, we have never heard it before. But the NASA Solar and Helioscopic Observatory, a spacecraft tasked with monitoring…

A strange incident occurred in the early hours of yesterday, March 13. The NASA Solar and Heliospheric Observatory (SOHO) detected that after a huge explosion, a powerful wave of coronal mass ejection (CME) escaped from the surface of the Sun. This event should not have concerned the Earth under normal circumstances since the event took place on the farside of the Sun (the side of the Sun opposite to the Earth). However, the CME blast was deemed extremely rare as it was traveling at a mind-numbing speed of 3000…
