Sun Unleashes Most Powerful Solar Flare Since 2017

On the 14th of December our star unleashed an X-class solar flare. Solar physicists classify strong flares into three categories, with C being the weakest, M the middling group and X the most potent.

A Gigantic Hole Just Opened Up in the Sun

A massive hole opened up in the Sun's atmosphere over the weekend, measuring more than 60 times the diameter of the Earth across at its peak.

Largest ever solar storm identified in a 14,300-year-old tree rings

A similar solar storm today would be catastrophic for modern technological society—potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions of pounds.

NASA Probe Sails Directly Through Sun's Intense Plasma Burst

The intrepid little spacecraft flew through a coronal mass ejection, helping scientists understand space weather.

Scientists discover the highest-energy light coming from the sun

The international team behind the discovery also found that this type of light, known as gamma rays, is surprisingly bright. That is, there's more of it than scientists had previously anticipated.

Meteor-Like 'Shooting Stars' Discovered in The Sun's Atmosphere

Meteor-like fireballs in the atmosphere of the Sun rain down like showers of shooting stars during the phenomenon of coronal rain, scientists have found.

NASA supercomputer makes predictions to give time to prepare for solar storms

The model uses AI to analyze spacecraft measurements of the solar wind and predict where an impending solar storm will strike, anywhere on Earth, with 30 minutes of warning. This could provide just enough time to prepare for these storms.

Second 'Giant Hole' Appears on Sun

  • 30 Mar 2023

A giant 'hole' has appeared on the surface of the Sun, and it could send 1.8 million-mph solar winds toward Earth by Friday.

A Powerful Solar Eruption on Far Side of Sun

A massive eruption of solar material, known as a coronal mass ejection or CME, was detected escaping from the Sun at 11:36 p.m. EDT on March 12, 2023. Even though the CME erupted from the opposite side of the Sun, its impacts were felt at Earth. 

Water From The Sun Has Been Found on The Moon

A new analysis of dust retrieved from the Moon suggests that water bound up in the lunar surface could originate with the Sun.

For the very first time, a spacecraft has "touched" the sun

NASA has sent a spacecraft, the Parker Solar Probe to the outer reaches of the sun’s atmosphere – the corona – where it spent five hours. This is the first time a spacecraft has come so close to the sun. 

Total solar eclipse plunges Antarctica into darkness

Totality was visible only in Antarctica on early Saturday, experienced by a small number of scientists experts and adventure tourists.

Parker solar probe becomes fastest object ever built

Nothing built by human hands has ever traveled faster than NASA's Parker Solar Probe. In late April, it smashed two wild space records. It was clocked at over 531,000 km/hour as it zipped through the sun's outer atmosphere.

The Solar System has a second plane

Almost all the objects orbiting the sun live in a particular plane. But a recent analysis of long-period comets reveals a second plane and it may be populated with comets.

Solar Cycle 25 has arrived. Here's what to expect

The sun goes through a regular 11-year cycle, swinging between periods of dormancy and periods of activity. Scientists have just announced that the sun will be ramping up in activity over the next few years.
