An X-Class solar flare — the most dangerous kind — erupted from the sun toward Earth today at 1:46 p.m. EDT from Active Region 2158. It's still unclear whether and to what extent the flare will affect power grids, satellites, or radio transmissions on Earth. But whether it wreaks havoc or not, it will be stunning to behold.
An X-Class solar flare — the most dangerous kind — erupted from the sun toward Earth Wednesday from Active Region 2158.
It’s still unclear whether and to what extent the flare will affect power grids, satellites, or radio transmissions on Earth. But whether it wreaks havoc or not, it will be stunning to behold.
But either way, on Thursday we will be able to see the flare in action, live on the Internet. The Slooh Space Telescope will be transmitting video of the sun from Prescott, Arizona, beginning on Thursday afternoon at 1:00 p.m. EDT.
Fierce solar blasts that could have badly damaged electrical grids and disabled satellites in space narrowly missed Earth in 2012, U.S. researchers said on Wednesday.
The bursts would have wreaked havoc on the Earth’s magnetic field, matching the severity of the 1859 Carrington event, the largest solar magnetic storm ever reported on the planet. That blast knocked out the telegraph system across the United States, according to University of California, Berkeley research physicist Janet Luhmann.
Global positioning system and radio transmissions may be degraded through Saturday as two solar eruptions strike Earth and affect its magnetic field.
The U.S. Space Weather Prediction Centre is tracking two two coronal mass ejections, “huge expulsions of magnetic field and plasma” that shot out of an area near the centre of the sun’s disc.
WASHINGTON — Northerners thawing out from a bitter freeze may get rewarded with shimmering northern lights over the next couple of days.
U.S. space weather forecaster Joe Kunches said the sun shot out a strong solar flare late Tuesday. It should shake up Earth’s magnetic field and expand the Aurora Borealis south. He said best viewing would probably be Thursday evening, weather permitting.
Gamma-ray bursts are the brightest and most powerful explosions that happen in the entire universe. And German researchers are now saying one may have hit Earth in the 8th century.
This would be a rarity, as gamma-ray bursts once every 10,000 to one million years per galaxy. According to V. V. Hambaryan and R. Neuhauser’s research on this electromagnetic event, “this is the first evidence for a short gamma-ray burst in our galaxy.”
NASA's Solar Dynamics Observatory has been keeping an eye on the sun for three years now, and in honor of that achievement, they have released this video of the changes our star has been through during the last three years. The video shows the increase in solar flares and coronal mass ejections (which send rivers of matter and radiation out into the solar system). The sun is reaching its 11-year solar maximum and the frequency of these events have been increasing.
