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...

[T]hough this proximity happens to be 20 times closer than the average long gamma-ray burst, it poses absolutely no danger to life on Earth. Rather, it's tremendously exciting – an event that could These bursts mark the end of the life of a massive star – a supernova or hypernova. They can also emerge from a collision between two neutron stars. Different gamma-ray burst profiles mean different kinds of explosions, which fade in different ways. When astronomers observed a collision between two neutron stars in 2017, it produced a...

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 first is that they cause electric currents to flow in Earth's upper atmosphere, heating the air...These geomagnetic storms can create beautiful auroras to appear over polar regions, but they can also disrupt radio signals and GPS. What's more, as...

The solar flare, classified as M8 in the second-most energetic category of flares, departed from the sun at 5:49 a.m. EDT (0949 GMT) on Friday, disrupting shortwave radio communications in the sun-facing parts of the world. According to Spaceweather.com(opens in new tab), amateur radio operators in Africa and the Middle East could have experienced signal distortion for up to one hour after the flare. The U.K. space weather forecaster Met Office predicts there is a chance of further flares today before the sunspot AR3098 disappears behind the sun's limb (the edge of the sun's visible disk). Space weather forecasters think...

The Sun has been up to some pretty intense shenanigans lately, but a recent eruption on the far side looks to be absolute science gold. On the evening of September 5 GMT, an enormous coronal mass ejection (CME) was recorded exploding on the far side of the Sun, sending a radiation storm out across the Solar System. It was a type known as a halo CME, in which an expanding halo of hot gas can be seen spewing out around the entire Sun. Sometimes this means that the CME is headed straight for Earth. However, this eruption was on the...

Heartwarming footage shows a three-month-old baby girl smiling after she was revived by an off-duty nurse when the infant stopped breathing on a plane. Tamara Panzino was a passenger on Spirit Airlines Flight 1691 on Thursday night from Pittsburgh, Pennsylvania, to Orlando, Florida, when a three-month-old infant called Anjelé suddenly became unresponsive about 30 minutes after takeoff, Fox35 reported. Panzino said she quickly reacted to the medical emergency on the aircraft by massaging the baby's chest and legs. Soon after, the baby was heard breathing again, much to the relief of her terrified parents.

A HUGE sunspot which doubled in size over a 24-hour period is now directly facing Earth, meaning a large solar flare could strike the planet. The sunspot, known as AR3038, doubled in size between Sunday and Monday night. Now, it has turned to face the Earth, sparking concerns that rapid solar winds could pelt towards the Blue Planet. And stunning footage from NASA's Solar Dynamics Observatory on Sunday shows how the huge sunspot has been evolving. Experts at Spaceweather.com explained: "Yesterday, sunspot AR3038 was big. "Today, it's enormous. The fast-growing sunspot has doubled in size in only 24 hours. "AR3038...

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...

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...

NASA satellites have observed a large sunspot forming on the surface of the Sun. The sunspot is twice as wide as Earth and it is facing away from us, for now. However, as Earth moves around the host star, the sunspot could fire a solar flare right at us. Astronomy site Space Weather said: “A new sunspot is emerging over the sun’s northeastern limb, and it’s a big one. “The sunspot’s primary core is twice as wide as Earth, and it is accompanied by two Moon-sized companion spots – dimensions which make it an easy target for amateur solar telescopes....

Amateur astronomer and Florida resident Howard Eskildsen snapped an image of the "light bridge"—which has a length that's roughly equal to the diameter of Mars—in a recently formed sunspot dubbed AR2770, spaceweather.com reported. These phenomena are caused by strong magnetic field concentrations, which inhibit convection—the transfer of heat from one place to another within gases and liquids. This process heats the solar surface. Hot "bubbles" of plasma—charged particles that are one of the four fundamental states of matter—are transported from deeper, hotter layers to the surface, whereas cooler plasma is transported back to the interior... According to Felipe, light bridges...

A massive sunspot on the Sun is turning towards our planet and this could result in strong solar flares. The sunspot AR2770 was detected earlier this week and is expected to grow in size in the upcoming days. A report by SpaceWeather.com - a space weather forecasting website - said that multiple minor flares have been emitted by the sunspot already as it faced towards the earth. These flares have caused "minor waves of ionization to ripple through Earth's upper atmosphere" but nothing major yet. A clear picture of the AR2770 has also surfaced that gives a better idea into...

Yet another series of solar flares(opens in new tab) series shimmied out from the sun on Friday (Aug. 26) after a dazzling show of green-hued auroras(opens in new tab) crashed through the atmosphere just days ago. "Sunspot AR3089 is crackling with a series of intensifying M-class [moderate] solar flares," SpaceWeather.com(opens in new tab) said in a Friday update. NASA's Solar Dynamics Observatory captured an especially powerful flare at 7:16 a.m. EDT (1116 GMT) as populations in Europe and Africa experienced a brief radio blackout.

The sunspot, known as AR3085, has also been shooting off several minor solar flares, though nothing strong enough to be disruptive on Earth. 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...

The Daocheng Solar Radio Telescope (DSRT) is under construction on a plateau in Sichuan province, southwest China. When completed, it will consist of 313 dishes, each with a diameter of 19.7 feet (6 meters), forming a circle with a circumference of 1.95 miles (3.14 kilometers). The telescope array will image the sun in radio waves to study coronal mass ejections (CMEs), large eruptions of charged particles from the sun's upper atmosphere, the corona. The project also includes the Chinese Spectral Radioheliograph for monitoring solar activity, which is being constructed (opens in new tab)in Inner Mongolia. The radioheliograph will consist of...

One of those bursts, called a coronal mass ejection, or CME, is expected to collide and consume another, creating what's called a cannibal CME event. According to The Weather Channel, these events can spark strong geomagnetic storms — and in this case, it's headed in our direction. NOAA expects that the CMEs will hit on Thursday, but before they do, the agency said that Earth will also be blasted on Wednesday with relatively fast solar winds, known as a recurrent coronal hole high speed stream. The solar winds alone could trigger a minor geomagnetic storm on Wednesday, but those conditions...

Acloud of "dark plasma" erupted from the sun on Sunday and is predicted to make contact with Earth on Wednesday, giving rise to the possibility of a minor geomagnetic storm. The eruption of material is known as a coronal mass ejection (CME)—a cloud of charged solar gas and magnetic fields. It was launched toward Earth on August 14 from a region of the sun known as AR3076. Solar activity news site spaceweather.com stated on Monday morning that the "plume of dark plasma" was traveling at over 1.3 million miles per hour. At that speed, it's expected to take a few...
