Solar flares and other phenomena can have a surprising effect on our Earthly activities.
The sun’s phenomena, like flares, can cause solar particles to enter the Earth’s atmosphere, with material effects.
The low solar corona as viewed in extreme ultraviolet light. Bright regions are where the most energetic solar storms are born. An eruption in action can be seen in the bottom-left.

Scientists spend years preparing for the two-minute window of a total solar eclipse.

It's true that here on Earth, if you want to burn something you need oxygen. But the Sun is different. It is not burning with the same kind of flame you would have on Earth if you burned a candle.
Solar flares captured on the Sun.
When dozens of US mines planted in waters off the Vietnam coast detonated almost simultaneously in 1972, all eyes turned to the Sun for an explanation.
A huge solar flare flashes in the middle of the sun on Sept. 6, 2017. A separate image of the Earth provides scale.
At a time in the sun's cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal mass ejections. What effects will Earth feel?
A gamma ray burst close to Earth could be devastating.
If we survive for another 7.59 billion years, our planet will spiral into the outer layers of the dying sun and melt away forever.
Coronal mass ejections can play havoc with Earthbound communications.
There's a disturbing history of solar flares taking out the technology we depend on. As tech becomes more and more vital, knowing what is happening in space is growing ever more crucial.

Our growing dependency on satellites for all forms of communication has made the problem of space weather even more acute.

Life on Earth may have started with a bit of sunshine and showers, followed with a light breeze of laughing gas and a sprinkle of hydrogen cyanide.
An artist’s illustration of Kappa Ceti whose stellar winds are 50 times stronger than our sun’s. Any Earth-like planet would need a magnetic field to protect its atmosphere if it was to stand a chance of hosting life.
In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.

Researchers have found out how to predict solar flares up to ten times faster than previous methods.
Tempestuous times on the solar surface.
It's the windiest place in the entire solar system – and these storms can be felt here on Earth.
Ain’t half hot: but where’s it heading?
Astrophysicists found out after the January 2014 solar flare that their predictions of solar weather were not very accurate. Here's the fix (kind of).
GPS is used in many devices to help us navigate.
It’s well known that severe space weather events – which are quite rare – can have a negative impact on our use of Global Positioning System (GPS) enabled devices. But our research, published in Geophysical…
Ten Earths could be laid across the diameter of the gigantic sunspot in AR2191 during its previous rotation – captured on October 23, 2014.

The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger. Last month, the solar active region known as AR12192 (also known as AR2192 to some of its…
During the early hours of this morning (3:42am AEST) our sun released a strong solar flare. It follows right on the heels of a more moderate flare that was released from the same region of the sun on Tuesday…
Like Icarus, passengers on aircraft during solar flares can cop the effects of flying close to the sun.
Space weather impacts many modern-day technologies. But one of the most concerning – and least reported – space weather effects is the increased radiation exposure to passengers on commercial long-distance…
New source of water?
Water ice is the most abundant solid material in the universe. Much of it was created as the byproduct of star formation…
Less than 10 % of global warming during the 20th century was due to changes in solar activity, new research has found. It…
How will Earth weather solar storms while the sun flips its magnetic field?
NASA Goddard Photo and Video
You may have read the sun’s magnetic field is heading for a change in field polarity - meaning it will flip upside down - and could have ripple effects throughout the entire solar system. So what does…
