    Billions of light years away, there is a giant ball of hot gas that is brighter than hundreds of billions of suns. It is hard to imagine something so bright. So what is it? Astronomers are not really sure, but they have a couple theories. They think it may be a very rare type of supernova — called a magnetar — but one so powerful that it pushes the energy limits of physics, or in other words, the most powerful supernova ever seen as of today. This object is so luminous that astronomers are having a really difficult time finding...

    More than 2,600 years ago, strange red clouds over Mesopotamia drew the attention of soothsayers across the land. Their royal reports have now helped confine the date of a severe solar storm that washed over the planet. Based on readings of carbon isotopes trapped in tree rings deposited around that time, astronomers already suspected there was a period of intense solar activity around the middle of the 7th century BC... And it seemed like it had pretty far-ranging effects. Earlier in the year, geologists reported similar signs of a storm from around this period in traces of radioactive particles buried...

    A mysterious shock wave in a gust of solar wind has sent a barrage of high-speed material smashing into Earth’s magnetic field, opening up a crack in the magnetosphere. The barrage of plasma could lead to a geomagnetic storm today (Dec. 19), according to spaceweather.com. The shockwave’s origins aren’t exactly known, but scientists think it could have come from a coronal mass ejection launched by the sunspot AR3165, a fizzing region on the sun’s surface that released a flurry of at least eight solar flares on Dec. 14, causing a brief radio blackout over the Atlantic Ocean. Sunspots are areas...

    In December 2021, a massive blast of energy hit the Earth’s atmosphere. Its source was a gamma-ray burst – one of the most powerful explosions in the universe – but not just any gamma ray burst. One scientist said at the time that the event – named GRB 211211A – “looks unlike anything else we have seen before The event was detected in December 2021 by NASA’s Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope. The gamma-ray burst was significantly longer than average, which might normally suggest it had been produced by the collapse of a massive star...

    The coronal hole is a gigantic solar gulf stretching across the sun’s center. Coronal holes are areas in the sun's upper atmosphere where our star's electrified gas (or plasma) is less hot and dense than in other regions, which makes them appear black in contrast. Around these holes,the sun's magnetic field lines, instead of looping back in on themselves, point outward into space, beaming solar material outwards at up to 1.8 million mph (2.9 million km/h)... This barrage of energetic solar debris, mostly consisting of electrons, protons and alpha particles, is absorbed by Earth’s magnetic field, which becomes compressed, triggering...

    On Nov. 3 a solar storm caused a temporary crack in Earth's magnetic field. The resulting hole enabled energetic particles to penetrate deep into the planet's atmosphere and set off extremely rare pink auroras. An explosion of extremely rare pink auroras recently lit up the night sky above Norway after a solar storm slammed into Earth and ripped a hole in the planet's magnetic field. The breach enabled highly energetic solar particles to penetrate deeper into the atmosphere than normal, triggering the unusual colored lights. The stunning light show was spotted Nov. 3 by a tour group led by Markus...

    A medium-intensity solar flare hit the Earth's magnetosphere in the early hours of Monday, Spaceweather.com reported. It is unlikely that a coronal discharge will follow the solar activity, and if it does, whether will head toward Earth. The recent solar flare came from the sunspot AR 3141, which has grown in size in the past 24 hours, EarthSky.org said in its report. The eruption was classified as an M5.2, even where M denotes the class of solar flares and is a medium-intensity eruption. In comparison, classes A, B, and C are low-intensity events, while Class X flares are wildly the...

    Named Miyake events after the lead author of the first study to describe them, the spikes occur roughly once every 1,000 years or so and are recorded as sudden increases in the radiocarbon levels of ancient tree rings. The leading theory among scientists is that Miyake events are solar flares that are 80 times more powerful than the strongest flare ever recorded. But a new study...suggests that the origin of the radiation bursts could be even more mysterious than first thought. Scientists have spotted six Miyake events in tree rings so far, indicated by sudden, single-year leaps in the concentrations...

    Yes, it could happen, but it would take a giant solar storm... Solar storms...occur when the sun releases an intense burst of electromagnetic radiation. This disturbance throws off waves of energy that travel outward, impacting other bodies in the solar system, including Earth. When the wayward electromagnetic waves interact with Earth's own magnetic field, they have a couple of effects.

    The sunspot that has been growing in size recently is known as AR3038. Footage from NASA's Solar Dynamics Observatory on Sunday shows how the sunspot has evolved over the past day or so, twisting and contorting. "Yesterday, sunspot AR3038 was big. Today, it's enormous," reads the SpaceWeather.com website. "The fast-growing sunspot has doubled in size in only 24 hours." The magnetic field associated with the sunspot means it could potentially send an M-class solar flare at Earth—the second-strongest type. However, it is not known whether this will be the case. As of Monday morning the National Oceanic and Atmospheric Administration's...

    The explosion comes courtesy of a dead sunspot called AR2987.... The sunspot explosion released loads of energy in the form of radiation, which also led to a coronal mass ejection (CME) — explosive balls of solar material — both of which could spur more intense northern lights in Earth's upper atmosphere. The material in that CME is likely to impact Earth on April 14...

    Just days after the Sun blasted Earth with an M-Class solar flare which created an unexpected G1-Class Geomagnetic Storm, the sun erupted another M-class solar flare towards the Earth earlier today. Today’s flare blasted the Earth with X-rays and UV radiation, triggering a shortwave radio black out over portions of the globe. On Saturday, NOAA forecasters said there was a risk of additional solar flares through today and as predicted, it occured. While Saturday’s solar flare erupted from sunspot Active Region-2911; today’s flare came from Active Regions 2908. In a statement released by NOAA’s Space Weather Prediction Center today, they...

The sunspot, known as AR3085, has also been shooting off several minor solar flares, though nothing strong enough to be disruptive on Earth. Sunspots are regions on the sun where magnetic fields are so intense that some heat is prevented from reaching the sun's surface. As such, sunspots may appear as dark patches. Due to the intense magnetic fields, sunspots are known sources of solar activity. When these magnetic field lines suddenly shift, a vast amount of...
