  • Solar Flare Downgraded But Still Can Brew Geomagnetic Storm, Say Experts
    Solar Flare Downgraded But Still Can Brew Geomagnetic Storm, Say Experts Fri, Sep 12, 2014

    Following Wednesday's solar flare, high frequency radio communications were disturbed for an hour as the ultraviolet radiation from the explosion ionised upper layers of the earth's atmosphere. The coronal mass ejection (CME) from sunspot AR1258 consisting of charged particles travelling towards earth has since been downgraded following a reduction in speed of the cloud from 3750 km/sec to 1400 km/sec. It is the combination of the latest flare with a slower flare that erupted on Monday, which could intensify the geomagnetic storm. The unusual pair of solar flares comes as the sun nears the peak of its 11-year cycle, when sunspots and solar storms become more frequent. More »

    The sun fired off an X-class solar flare, the most powerful classification, at 1:46 pm EDT from Active Region 2158 today. According to Nasa officials, the solar flare qualifies as an X1.6 storm but confirmed that it poses no danger to anyone on Earth or the astronauts living in the International Space Station. National Weather Service's Space Weather Prediction Center (SWPC) wrote in an online update, "Impacts to HF [high-frequency] radio communications on the daylight side of Earth are expected to last for more than an hour." The National Weather Service's Space Weather Prediction Center wrote on its Facebook page, "Initial information suggests that CME is likely associated with this event, but further analysis is underway at this time,"  More »

    Solar Flare Could Disrupt Power Grids And Communications Thu, Sep 11, 2014

    A blast of electrically charged particles from a solar flare is aimed at earth and could disrupt power grids, radio transmissions and orbiting satellites in the coming days. The origin of the extreme X-flare is the sunspot region in the middle of the sun and is known as AR2158, reports NBC News. X-flares are among the strongest of solar flares. Solar storms happen often, especially during peaks in the solar cycle and do not directly harm people. More »

    Update for 5:20 pm ET Sept. 11: The solar storms this week may amplify Earth's aurora displays. A big storm erupted on the sun today (Sept. 10), and Earth was in the crosshairs. Both space weather events were captured on camera by NASA's sun-watching Solar Dynamics Observatory spacecraft. Today's solar flare qualifies as an X1.6 storm but poses no danger to anyone on Earth or the astronauts living aboard the International Space Station, NASA officials told Space.com. More »

    A huge tendril of super-hot plasma that had been creeping across the face of the sun erupted Tuesday (Sept. 2) in a striking solar storm that may send a wave of charged particles in Earth's direction. Video of the solar eruption captured by NASA's sun-watching Solar Dynamics Observatory shows a cloud of solar plasma being hurled from the sun's surface during the rippling blast. More »

    Nasa: How Solar Flare From the Sun Caused 'Dazzling' Aurora Display Thu, Aug 21, 2014

    A solar flare was responsible for causing a "dazzling" aurora display above North America earlier this week. Nasa has said the northern lights, captured by International Space Station astronaut Reid Wiseman, were a result of a giant cloud of gas from the sun colliding with Earth's magnetic field. The cloud of gas from the sun, or a coronal mass ejection, collided with the magnetic fields on 19 August, setting off a geomagnetic storm, the space agency explained. The solar flare was released from the sun on 15 August. More »

    Intense Solar Storm Expected to Strike Earth on Friday 13th Thu, Jun 12, 2014

    The sun released three powerful solar flares within two days and the effects of this are expected to reach Earth tomorrow. All were X-Class flares – the most intense of all solar flares – and were around 10,000 times as powerful as normal flares from the Sun. Explaining how this will affect Earth, the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Centre said the storm will reach our planet on Friday 13. "After producing a pair of R3 (Strong) Radio Blackouts in quick succession yesterday morning, active Region 2087 produced yet another R3 event today," NOAA said in a statement. More »

  • Solar Flare Could Hit Earth On Friday 13th
    Solar Flare Could Hit Earth On Friday 13th Thu, Jun 12, 2014

    A trio of major solar flares could spell trouble for Earth on Friday 13th, scientists have warned. "Impacts from this activity were short-lived and affected high-frequency communications for the daylit side of Earth at the time of the flare," said a statement on the National Oceanic and Atmospheric Administration (NOAA) website . "A Coronal Mass Ejection associated with the activity has been observed moving at a flank from Earth and a glancing blow to Earth from this event is expected on June 13." A Coronal Mass Ejection releases vast amounts of matter and electromagnetic radiation - resulting in a threat to high-frequency communication systems used by weather stations, aviators, government time stations and international shortwave broadcasters, among others.

    Nasa Captures Sun's Dramatic Solar Flares Wed, Jun 11, 2014

    The sun put on a dramatic light show display, with a sunspot emitting two bright solar flares in quick succession. The flares were powerful enough to temporarily interfere with radio communications in Europe. A solar flare is defined as a sudden, rapid and intense variation in brightness. It occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. More »

    The solar flares were captured by Nasa's Solar Dynamics Observatory. A solar flare is a powerful burst of radiation. "An X2 is twice as intense as an X1, an X3 is three times as intense," Nasa explained. "Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground," Nasa said. More »

  • Powerful Solar Flare Sheds Light on Sun Eruption Theories
    Powerful Solar Flare Sheds Light on Sun Eruption Theories Wed, May 21, 2014

    For the first time, a massive solar flare revealed the process that created it, confirming new theories about flares and the explosive ejections of solar material often linked with them, a new study reports. Understanding how solar flares form brings scientists a step closer to predicting them, along with the dangerous space weather that has the power to damage satellites and power grids on Earth, researchers said. Captured by NASA's Solar Dynamics Observatory (SDO) spacecraft, the massive solar flare occurred on July 12, 2012 — less than a week after the publication of a new 3D model that suggested similar flares are driven by a process known as slipping reconnection, in which magnetic field lines disconnect and reconnect. "The 2D standard solar flare model captures much of the physics involved, but has the inherent limitation of being a 2D model," said study lead author Jaroslav Dudik of the University of Cambridge.

    How Big is the Universe? Astronomers Measure Rate of Expansion Using Over 140,000 … Tue, Apr 8, 2014

    Using the most precise measurements to date, astronomers have confirmed that although the universe continues to expand, it's doing so at a slower rate than they used to believe. The study, which is the latest result to come from the Baryon Oscillation Spectroscopic Survey (BOSS), used over 140,000 distant quasars to measure matter and intergalactic gas, in order to estimate the rate at which the cosmos in pushing itself apart. Dr Matthew Pieri, a BOSS team-member from Portsmouth University, told the BBC: "This is the most precise measurement that's every been done, and all I'll say at the moment is that there is a tension there. Andreu Font-Ribera, who studied the expansion using quasars at the Lawrence Berkeley National Laboratory, told Nature World News: "If we look back to the universe when galaxies were three times closer together than they are today, we'd see that a pair of galaxies separated by a million light-years would be drifting apart at a speed of 68km per second as the universe expands."
