According to Nasa scientists a recent spate of furious eruptions on the surface of the sun hurled a huge amount of heat toward Earth. This is the biggest dose our planet has received from our closest star in seven years. Although the influx of solar energy puffed up the atmosphere, increasing drag on low-orbiting satellites, it caused fewer disruptions to electronic infrastructure such as electronic grids than some expected.View More Solar Storm Blasted Earth With Powerful Dose of Energy
Two new solar flares erupted from the sun on March 10, blasting streams of plasma and charged particles into space. The outbursts were both categorized as M-class solar flares, and exploded from the surface of the sun at 12:27 a.m. EST(0527 GMT) and 12:44 p.m. EST (1744 GMT), respectively, according to NASA’s Goddard Space Flight Center in Greenbelt, Md.
These two flares came from the same Active Region (AR) on the sun, designated number 1429, that has already produced three X-class and numerous M-class flares over the past week.
Outbursts from the sun over the past week gave the best opportunity for skywatchers to catch an amazing views of auroras recently. The glowing auroras, also called the northern and southern lights, are caused when charged particles from the sun collide with Earth’s magnetic field. These charged particles are in abundance lately in the wake of a series of super-charged solar eruptions that began on March 6.View More Skywatchers Catch an Amazing Views of Auroras
The European Space Agency’s Venus Express probe, which is located much closer to the sun than Earth, experienced high doses of radiation from the recent solar storm, and on Tuesday (March 6) at 8:40 p.m. EST (0140 GMT March 7), spacecraft operators reported that Venus Express’ onboard startracker cameras had become blinded. According to Octavio Camino, the Venus Express spacecraft operation manager at ESA’s European Space Operations Center in Darmstadt, Germany after being bombarded by solar radiation Tuesday, the cameras were unable to pick up any stars.View More Solar Storm Blinds Venus Spacecraft
As scientists say powerful solar storm that slammed into Earth on March 8 triggered weaker than expected disruptions, but may still have a few more tricks up its sleeve. Two huge X-class solar flares that are the most powerful type of sun storm erupted from the sun late on March 6, hurling a wave of plasma and energetic particles toward Earth. This blast, called a coronal mass ejection, reached Earth at around 5:45 a.m. EST (1045 GMT) on March 8, according to officials at the Space Weather Prediction Center, which is jointly managed by the National Oceanic and Atmospheric Administration (NOAA) and the National Weather Service.View More Powerful Solar Storm Triggered Weaker than Expected Disruptions
A most powerful solar flare erupted from the sun on March 4 sending an explosion of plasma and charged particles hurtling toward Earth. Flares occur when accelerated charged particles, mainly electrons, interact with the plasma medium. Solar flares, depending on the power of X-ray, are classified as A, B, C, M or X. According to the Space Weather Prediction Center operated by the National Weather Service the latest flare was an X1.1-class solar flare and exploded from the surface of the sun at 11:13 p.m. EST (0413 GMT March 5).View More Sun Major Solar Flares
Sun unleashed five solar eruptions in only two days last week. The solar storms flared up between February 23 and 24 and exploded from nearly all areas of the star, including the top, bottom, left and right sides of the solar disk as seen by space-based observatories, according to NASA scientists. In fact, four of these outbursts came within a single 24-hour period. One of the eruptions churned out an impressive magnetic filament in the early hours of February 24. This triggered the first of two coronal mass ejections (CMEs) that were blasted toward Earth.View More Sun Unleashed 5 Solar Eruptions in 2 Days
Astronauts aboard the International Space Station are on a quest to snap photos of the northern lights. The space station crew has already beamed home dazzling photos and videos of Earth’s auroras, including a series of movies released by NASA last week. Now, the astronauts are teaming up with Canadian scientists on Earth in a coordinated campaign to track the northern aurora displays. Throughout February and March, NASA astronauts Don Pettit and Dan Burbank will be on the lookout for flare-ups of the northern lights, also known as the aurora borealis, over Canada.View More Astronauts Track Northern Lights
A powerful solar eruption is expected to blast a stream of charged particles toward Earth on January 24, as the strongest radiation storm since 2005 rages on the sun. The solar flare spewed from sunspot 1402, a region of the sun that has become increasingly active lately. Several NASA satellites, including the Solar Dynamics Observatory, the Solar Heliospheric Observatory (SOHO), and the Stereo spacecraft observed the massive sun storm. According to NOAA, this is the strongest solar radiation storm since May 2005. A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth’s magnetic field on January 24-25 as it sails mostly north of our planet.View More Strongest Solar Radiation Storm in 7 Years
