Solar storm March 2012: OUR SOLAR SYSTEM

 

'It's hitting us right in the nose': Largest solar flare in six years to hit Earth today - and could 'jolt' everything from flights and GPS systems to entire power grids

  • 'X-class' flare is most powerful kind of solar flare
  • Two years of violent solar storms predicted

 

The largest solar flare in six years is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and aeroplane flights.

The sun erupted Tuesday evening, and the effects should start smacking Earth around 7 a.m. EST Thursday, according to forecasters at the federal government's Space Weather Prediction Center. They say the flare is growing as it speeds outward from the sun.

'It's hitting us right in the nose,' said Joe Kunches, a scientist for the National Oceanic and Atmospheric Administration. He called it the sun's version of 'Super Tuesday'.

The X1 solar flare in a new active region on the sun, region 1429. It has let loose two M-class flares and one X-class so far. Material erupted from the sun with each flare, though due to the fact that this active region is still off to the side of the sun, they will likely have a weak effect on Earth's magnetosphere

The solar storm is likely to last through Friday morning, but the region that erupted can still send more blasts our way, Kunches said. He said another set of active sunspots is ready to aim at Earth right after this.

But for now, scientists are waiting to see what happens Thursday when the charged particles hit Earth at 4.5 million mph.

NASA solar physicist Alex Young added, 'It could give us a bit of a jolt.' But he said this is far from a super solar storm.

The storm is coming after an earlier and weaker solar eruption happened Sunday, Kunches said. This newer blast of particles will probably arrive slightly later than forecasters first thought.

That means for North America the 'good' part of a solar storm — the one that creates more noticeable auroras or Northern Lights — will peak Thursday evening. Auroras could dip as far south as the Great Lakes states or lower, Kunches said, but a full moon will make them harder to see.

The explosions on the sun created a 'coronal mass ejection' which sent a large amount of charged particles into space, but they are expected to avoid Earth because the sun spots are off to the side of our star

Auroras are 'probably the treat we get when the sun erupts,' Kunches said.

But there is the potential for widespread problems. Solar storms have three ways they can disrupt technology on Earth: with magnetic, radio and radiation emissions. This is an unusual situation when all three types of solar storm disruptions are likely to be strong, Kunches said.

That means 'a whole host of things' could follow, he said.

The magnetic part of the storm has the potential to trip electrical power grids. Kunches said power companies around the Earth have been alerted for possible outages. The timing and speed of the storm determines whether it will knock off power grids, he said.

This flare was categorized as an X5.4, making it the second largest flare -- after an X6.9 on August 9, 2011 -- since the sun's activity segued into a period of relatively low activity called solar minimum in early 2007

In 1989, a strong solar storm knocked out the power grid in Quebec, causing 6 million people to lose power.

Solar storms can also make global positioning systems less accurate, which is mostly a problem for precision drilling and other technologies, Kunches said. There also could be GPS outages.

The storm also can cause communication problems and added radiation around the north and south poles, which will probably force airlines to reroute flights. Some already have done so, Kunches said.

Satellites could be affected by the storm, too. NASA spokesman Rob Navias said the space agency isn't taking any extra precautions to protect astronauts on the International Space Station from added radiation from the solar storm.

 

The giant black hole at the centre of the Milky Way may be devouring asteroids, creating flares that can be observed from Earth around once a day.

Nasa scientists detected X-ray flares from the supermassive black hole known as Sagittarius A* - the flares last a few hours, and can be 100 times brighter than the black hole's normal energy output.

The black hole is surrounded by a cloud of trillions of asteroids and comets, say the scientists - and asteroids passing within 100 million miles of Sagittarius A*, the distance between Earth and the sun, will be pulled in and vapourised.

The panel on the left shows a very long Chandra observation of the region around the Sgr A*, the black hole at the centre of the Milky Way

'People have had doubts about whether asteroids could form at all in the harsh environment near a supermassive black hole,' said Kastytis Zubovas of the University of Leicester in the United Kingdom. 'Our study suggests that a huge number of them are needed to produce these flares.'

'An asteroid’s orbit can change if it ventures too close to a star or planet near Sgr A*,' said co-author Sergei Nayakshin, also of the University of Leicester. 'If it’s thrown toward the black hole, it’s doomed.'

The flares - which have also been detected in infrared by the European Southern Observatory's Very Large Telescope in Chile - are thought to be created by space rocks above twelve miles in diameter.

The black hole may also be 'eating' smaller rocks, but the flares would be more difficult to spot.

Asteroids passing too close to the black hole - a huge object with a mass estimated to be at least half a million Suns - would be vaporized by friction as they pass through the hot, thin gas flowing into Sgr A*, similar to a meteor heating up and glowing as it falls through Earth’s atmosphere.

A flare is produced as the asteroid is swallowed eventually by the black hole.

A new study suggests that there is a cloud around Sgr A* containing trillions of asteroids and comets, stripped from their parent stars. The flares occur when asteroids of six miles or larger in radius are consumed by the black hole

Zubovas and his colleagues suggest there is a cloud around Sgr A* containing trillions of asteroids and comets, stripped from their parent stars.

These results agree with theories of how many asteroids are likely to be in this region, assuming that the number around stars near Earth is similar to the number surrounding stars near the center of the Milky Way.
'As a reality check, we worked out that a few trillion asteroids should have been removed by the black hole over the 10-billion-year lifetime of the galaxy,' said co-author Sera Markoff of the University of Amsterdam in the Netherlands. 'Only a small fraction of the total would have been consumed, so the supply of asteroids would hardly be depleted.'
Planets thrown into orbits too close to Sgr A* also should be disrupted by tidal forces, although this would happen much less frequently than the disruption of asteroids, because planets are not as common.

Such a scenario may have been responsible for a previous X-ray brightening of Sgr A* by about a factor of a million about a century ago. While this event happened many decades before X-ray telescopes existed, Chandra and other X-ray missions have seen evidence of an X-ray 'light echo' reflecting off nearby clouds, providing a measure of the brightness and timing of the flare.
“This would be a sudden end to the planet’s life, a much more dramatic fate than the planets in our solar system ever will experience,”

An enormous flare which erupted from the remnants of an exploded star in a faraway constellation has left Nasa scientists baffled.

Last month, the famous Crab Nebula supernova, first observed in 1731, gave off a flare five times more powerful than any previously seen from the object.

On April 12, Nasa's Fermi Gamma-ray Space Telescope first detected the outburst, which lasted six days.

The nebula is the wreckage of an exploded star that emitted light which reached Earth in the year 1054.

It is located 6,500 light-years away in the constellation Taurus. At the heart of an expanding gas cloud lies what is left of the original star's core, a superdense neutron star that spins 30 times a second.

With each rotation, the star swings intense beams of radiation toward Earth, creating the pulsed emission characteristic of spinning neutron stars, known as pulsars.

Apart from these pulses, astrophysicists believed the Crab Nebula was a virtually constant source of high-energy radiation.

But in January, scientists associated with several orbiting observatories, including NASA's Fermi, Swift and Rossi X-ray Timing Explorer, reported long-term brightness changes at X-ray energies.

'The Crab Nebula hosts high-energy variability that we're only now fully appreciating,' said Rolf Buehler, a member of the Fermi Large Area Telescope (LAT) team at the Kavli Institute for Particle Astrophysics and Cosmology, a facility jointly located at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University.

Since 2009, Fermi and the Italian Space Agency's AGILE satellite have detected several short-lived gamma-ray flares at energies greater than 100 million electron volts (eV) -- hundreds of times higher than the nebula's observed X-ray variations. For comparison, visible light has energies between 2 and 3 eV.

On April 12, Fermi's LAT, and later AGILE, detected a flare that grew about 30 times more energetic than the nebula's normal gamma-ray output and about five times more powerful than previous outbursts.

On April 16, an even brighter flare erupted, but within a couple of days, the unusual activity completely faded out.

'These superflares are the most intense outbursts we've seen to date, and they are all extremely puzzling events,' said Alice Harding at NASA's Goddard Space Flight Center in Greenbelt, Md. 'We think they are caused by sudden rearrangements of the magnetic field not far from the neutron star, but exactly where that's happening remains a mystery.'

The Crab's high-energy emissions are thought to be the result of physical processes that tap into the neutron star's rapid spin. Theorists generally agree the flares must arise within about one-third of a light-year from the neutron star, but efforts to locate them more precisely have proven unsuccessful so far.

Since September 2010, NASA's Chandra X-ray Observatory routinely has monitored the nebula in an effort to identify X-ray emission associated with the outbursts. When Fermi scientists alerted astronomers to the onset of a new flare, Martin Weisskopf and Allyn Tennant at NASA's Marshall Space Flight Center in Huntsville, Ala., triggered a set of pre-planned observations using Chandra.

'Thanks to the Fermi alert, we were fortunate that our planned observations actually occurred when the flares were brightest in gamma rays,' Weisskopf said. 'Despite Chandra's excellent resolution, we detected no obvious changes in the X-ray structures in the nebula and surrounding the pulsar that could be clearly associated with the flare.'

Scientists think the flares occur as the intense magnetic field near the pulsar undergoes sudden restructuring. Such changes can accelerate particles like electrons to velocities near the speed of light. As these high-speed electrons interact with the magnetic field, they emit gamma rays.

To account for the observed emission, scientists say the electrons must have energies 100 times greater than can be achieved in any particle accelerator on Earth.

This makes them the highest-energy electrons known to be associated with any galactic source.

Based on the rise and fall of gamma rays during the April outbursts, scientists estimate that the size of the emitting region must be comparable in size to the solar system.

A huge tornado five times the size of Earth erupted on the sun's surface, with superheated gases whirling at more than 100,000 miles per hour.

The tornado is up to two MILLION degrees centigrade.

Dr. Huw Morgan, co-discover of the solar tornado, adds, ‘This unique and spectacular tornado must play a role in triggering global solar storms.’

Superheated gases as hot as 50,000 to 2,000,000 Kelvin were sucked from the root of a dense structure called a prominence, spiralling up into the high atmosphere

‘This is perhaps the first time that such a huge solar tornado is filmed by an imager,’ says Dr. Xing Li, of Aberystwyth University.

Superheated gases as hot as 50,000 to 2,000,000 Kelvin were sucked from the root of a dense structure called a prominence, and spiral up into the high atmosphere and travel about 200,000 kilometres for at least three hours.

The tornadoes were observed on 25 September 2011.

The hot gases in the tornadoes have speeds as high as 300,000 km per hour. Gas speeds of terrestrial tornadoes can reach 150 km per hour.

The tornadoes often occur at the root of huge coronal mass ejections. When heading toward the Earth, these coronal mass ejections can cause significant damage to the Earth’s space environment, satellites, even knock out the electricity grid.

The solar tornadoes drag winding magnetic field and electric currents into the high atmosphere. It is possible that the magnetic field and currents play a key role in driving the coronal mass ejections.

SDO was launched in February 2010. The satellite is orbiting the Earth in a circular, geosynchronous orbit at an altitude of 36,000 kilometres.

It monitors constantly solar variations so scientists can understand the cause of the change and eventually have a capability to predict the space weather.

The sun unleashed an unusually powerful solar flare yesterday, the largest in nearly five years.

The eruption launched a ten billion ton storm cloud hurtling through space at five million miles per hour.

Scientists said the event took place on the side of the sun that was not facing Earth, so there will be little impact to satellites and communication systems.

SOLAR FLARE ‘TO HIT BRITAIN’

An enormous solar flare expected to hit Britain could blow out the national grid leaving the entire country without electricity, scientists warned in June.

Energy Secretary Chris Huhne is considering a raft of options to protect electricity supplies including switching off the national grid entirely, causing temporary blackouts.

It is believed that as the sun reaches a peak in activity over the next two years, it could unleash a ‘class 5′ flare, which might knock out computer systems and even throw satellites off course.

Scientists believe the flare would be up to five times more powerful than one which hit Quebec in 1989 and left six million people without power.

The initial blast from the solar flare could reach Earth in a matter of minutes. This would be followed by a second, potentially more dangerous wave of energy which would take up to three days to arrive.

It means the Government would have enough time to implement a contingency plan.

This could include switching off the electricity network entirely and ensuring planes are flown at lower altitudes in order to reduce their exposure to radiation.

Joe Kunches at the U.S. government’s Space Weather Prediction Center in Colorado said there were reports of brief short-wave radio disruptions in Asia, but little else.

He said: ‘We lucked out because the site of the eruption at the sun was not facing the Earth, so we will probably feel no ill-effects.’

The image was captured by Nasa’s Solar Dynamics Observatory in extreme ultraviolet light at 131 Angstroms.

The sun is transitioning from a quiet period into a busier cycle. Scientists estimate there will be a spike in the number of such solar eruptions over the next three to five years.

The last time there was such a strong solar flare was in December 2006.

 

 

 

 

Right at this moment, robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn. Several others are on their way to smaller bodies, and a few are heading out of the solar system entirely. Although the Space Shuttle no longer flies, astronauts are still at work aboard the International Space Station, performing experiments and sending back amazing photos. With all these eyes in the sky, I'd like to take another opportunity to put together a recent photo album of our solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries. This time, we have some closer views of the asteroid Vesta, a visit to the durable (if dusty) Mars rover Opportunity, some glimpses of Saturn's moons, and lovely images of our home, planet Earth.

From detailed solar flares to an amazing image of Jupiter and two of its moons, this tour of our solar system has been captured by an amateur British astronomer in his back garden.

Damian Peach, an electronic engineer from Selsey, West Sussex, has spent the last ten years documenting the changing face of our solar system.

Spending a relatively modest £10,000 on a high-speed telescope and electrical equipment, Mr Peach's crystal clear images are good enough to stand alongside those of Nasa and the European Southern Observatory in Chile.

So much so that in 2010, he became the only Briton to win the prestigious Astronomy Photographer Of The Year Award for his composite photograph of Jupiter's moons, Ganymede and Io, orbiting the stormy surface of the gas giant.

Mr Peach said: 'It's just fantastic that it's possible to do something like this from your own back garden.

'This has been made possible by recent leaps in technology. These days surprisingly good results are possible with small telescopes and low cost webcams.

'The results possible for home astronomers now were not achievable until the 1990s by even the largest telescopes on Earth.

'The resolution possible with large amateur telescopes could now be considered of a professional quality in what the images reveal on the planets.'

'The planets have dynamic changing weather patterns much as Earth does, though in most cases on a far more dramatic and grand scale.

'With Jupiter, you are seeing a world of gas littered with storms of almost every shape and size. The clouds are in constant motion and changes are easily visible from day-to-day.

'The colours you see in the images are real, and very close to how the planets would appear could you go there and visit the them.'

Mr Peach's home kit includes a 356mm reflecting telescope manufactured by Celestron USA, with a high-speed video camera called a Flea3.

Having this relatively low-cost technology available to anyone means that a network of hobbyist astronomers across Britain are constantly observing the night sky and sharing their findings.

'I am part of a larger group of astronomers involved in longer term study,' Mr Peach said.

'Detailed reports of activity are produced by organisations such as the British Astronomical Association. Our observing programs and goals have been, and continue to be, very successful.'
