Huge blasts of sun’s plasma hurtling toward Earth

A huge mass of magnetically charged material ejected from the sun is racing across space toward our planet, where it is expected to arrive on Tuesday. When it strikes the Earth’s magnetic field, it could produce spectacular auroras.

A blast of violent space weather could hit the Earth tomorrow following two massive explosions on the Sun. NASA astronomers witnessed a huge flare above a giant sunspot the size of our planet and linked to an even larger eruption across the surface of Sun.

Experts estimate a wave of supercharged gas called plasma will reach us this Tuesday when it will buffet the natural magnetic shield protecting Earth. It could trigger spectacular displays of the aurora or northern and southern lights.

The solar outbursts on Sunday August 1 were recorded by several satellites including NASA’s new Solar Dynamics Observatory which watched its shockwave rippling outwards. The flare over the sunspot was swiftly followed by an eruption 250,000 miles (400,000 km) away in a feature called a filament.

UK solar expert Dr Lucie Green, of the Mullard Space Science Laboratory, in Surrey, followed the flare-ups using Japan’s orbiting Hinode telescope.

She said last night: “What wonderful fireworks the Sun has been producing! This was a very rare event – not one, but two almost simultaneous eruptions from different locations on the sun were launched toward the Earth.

“These eruptions occur when immense magnetic structures in the solar atmosphere lose their stability and can no longer be held down by the sun’s huge gravitational pull. Just like a coiled spring suddenly being released, they erupt into space.

“It looks like the first eruption was so large that it changed the magnetic fields throughout half the Sun’s visible atmosphere and provided the right conditions for the second eruption. Both eruptions could be Earth-directed but may be travelling at different speeds. This means we have a very good chance of seeing major and prolonged effects, such as the northern lights at low latitudes.”

. . .

Scientists have warned that a really big solar eruption, like the Carrington Event witnessed from Surrey in 1859, could destroy satellites and wreck power and around the globe if it happened today.

Such an event would be the biggest disaster ever to hit mankind, preventing the production of essential supplies including food, water and medicines. Other eruptions have been observed directed towards us but thankfully less severe.

Self destructing Supernova explosion may wipe out earth

A STAR is primed to explode in a blast that could wipe out the Earth, according to American astronomers.

A new study shows the star, called T Pyxidis, is much closer than previously thought at 3,260 light-years away – a short hop in galactic terms.

It is set to self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT.

The blast from the thermonuclear explosion could strip away the Earth’s ozone layer that keeps out deadly space radiation, scientists said.

The doomsday scenario was described today by astronomers from Villanova University in Philadelphia.

They said the International Ultraviolet Explorer satellite has shown them that T Pyxidis is really two stars, one called a white dwarf that is sucking in gas and steadily growing. When it reaches a critical mass it will blow itself to pieces.

It will become as bright as all the other stars in the galaxy put together and shine like a beacon halfway across the universe.

The experts said the Hubble space telescope photographed the star gearing up for its big bang with a series of smaller blasts or “burps”, called novas.

These explosions came regularly about every 20 years from 1890, but stopped after 1967.

So the next blast is very overdue, said scientists Edward M Sion, Patrick Godon and Timothy McClain at the American Astronomical Society in Washington.

Robin Scagell, vice-president of the UK’s Society for Popular Astronomy, said, “The star may certainly became a supernova soon – but soon could still be a long way off so don’t have nightmares.”
