A new study published in Nature’s Scientific Reports by researchers at the Danish National Space Institute at the Technical University of Denmark (DTU) and The Hebrew University of Jerusalem suggests that the Sun’s activity in screening cosmic rays affects clouds and, ultimately, the Earth's energy budget with concomitant climatic effects. Science editor David Whitehouse interviews Professor Henrik Svensmark, one of the study's authors.

Our sun has been behaving very strangely, and this unusual behavior is really starting to affect our weather patterns. There have been virtually no sunspots in 2018 as solar activity has dropped to alarmingly low levels. As a result, our atmosphere has been cooling and shrinking, and experts are warning that we are heading for a bitterly, bitterly cold winter. And even though the official start of winter is well over a month away, winter weather is already sweeping the nation. As you will see below, a giant winter storm is about to slam into the east coast, but what...

As you can see, the low sunspot activity of the past two months continued in January. November 2017 remains the most inactive month for sunspots since the middle of 2009. January is now the second most inactive month, with December a very close third...Regardless, the low activity, this soon, continues to suggest that the next maximum will also be weak, and might even not come at all, as some solar scientists have proposed. Instead, we might be heading toward another Grand Minimum, with no significant sunspots for decades.

Astonishing images from NASA reveal no visible sunspots are currently visible on its surface. This has caused the star to go into "cue call" mode having entered its quietest period for more than a century, Vencore Weather claims. Decreased activity is not unusual as solar activity changes the volatile star's surface in 11-year cycles, astronomers say. But researchers are warning this current cycle could have a devastating impact on Earth's atmosphere, possibly ushering in a second ice age, similar to the one which began in 1645. Paul Dorian of Vencore Weather says the blank Sun is a sign that the...

'Something unexpected' is happening on the Sun, Nasa has warned. This year was supposed to be the year of 'solar maximum,' the peak of the 11-year sunspot cycle. But as this image reveals, solar activity is relatively low.

Even small changes in solar activity can impact Earth's climate in significant and surprisingly complex ways, researchers say. The sun is a constant star when compared with many others in the galaxy. Some stars pulsate dramatically, varying wildly in size and brightness and even exploding. In comparison, the sun varies in the amount of light it emits by only 0.1 percent over the course of a relatively stable 11-year-long pattern known as the solar cycle. Still, "the light reaching the top of the Earth's atmosphere provides about 2,500 times as much energy as the total of all other sources combined,"...

A major solar flare erupted from the sun late last night (March 4) sending an explosion of plasma and charged particles hurtling toward Earth. The 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), according to the Space Weather Prediction Center operated by the National Weather Service. X-class flares are the most powerful type of solar storm, with M-class eruptions falling within the mid-range, and C-class flares being the weakest.

GENEVA (AP) -- A senior official at the U.S. National Oceanic and Atmospheric Administration says solar storms pose a growing threat to criticial infrastructure such as satellite communications, navigation systems and electrical transmission equipment. NOAA Assistant Secretary Kathryn Sullivan says the intensity of solar storms is expected to peak in 2013 and countries should prepare for "potentially devastating effects." Solar storms release particles that can temporarily disable or permanently destroy fragile computer circuits. Sullivan, a former NASA astronaut who in 1984 became the first woman to walk in space, told a U.N. weather conference in Geneva on Tuesday that "it...

The risk of a devastating space storm wreaking havoc like a "global Katrina" and costing the world trillions of pounds should be taken "seriously", claims Britain's top scientist. Professor Sir John Beddington, the Government's chief scientist, said that the Sun was waking up from a quiet period and was likely to throw a lot more "space weather" at the Earth. Also, the world was increasingly vulnerable to damage because of our dependence on satellites, communication networks and computer devices. If a solar storm hit the Earth, it could throw out navigation systems, crash stock markets, ground aircraft and cause power...

The sun unleashed a powerful flare Thursday (Feb.24) that – while not the strongest solar storm ever seen – let loose a massive wave of magnetic plasma in a dazzling display. The solar flare kicked up a huge, twisting tendril of plasma that scientists call a solar prominence. NASA's Solar Dynamics Observatory recorded the flare in an eye-catching video, with mission scientists calling the eruption a "monster prominence."

Prompted by a recent increase in solar activity, more than a hundred researchers and government officials are converging on Helwan, Egypt, to discuss a matter of global importance: storms from the sun. The “First Workshop of the International Space Weather Initiative (ISWI)” meets Nov. 6th through 10th and is convened by the United Nations, the National Aeronautics and Space Administration (NASA), and the Japan Aerospace Exploration Agency (JAXA). "Strong solar storms can knock out power, disable satellites, and scramble GPS," says meeting organizer and ISWI executive director Joe Davila of NASA's Goddard Space Flight Center. "This meeting will help us...

Scientists studying sunspots for the past 2 decades have concluded that the magnetic field that triggers their formation has been steadily declining. If the current trend continues, by 2016 the sun's face may become spotless and remain that way for decades—a phenomenon that in the 17th century coincided with a prolonged period of cooling on Earth. Sunspots appear when upwellings of the sun's magnetic field trap ionized plasma—or electrically charged, superheated gas—on the surface. Normally, the gas would release its heat and sink back below the surface, but the magnetic field inhibits this process. From Earth, the relatively cool surface...

When probing the deepest reaches of the Cosmos or magnifying our understanding of the quantum world, a whole host of mysteries present themselves. This is to be expected when pushing our knowledge of the Universe to the limit. But what if a well-known -- and apparently constant -- characteristic of matter starts behaving mysteriously? This is exactly what has been noticed in recent years; the decay rates of radioactive elements are changing. This is especially mysterious as we are talking about elements with "constant" decay rates -- these values aren't supposed to change. School textbooks teach us this from an...

Melbourne, Aug 26 (ANI): Astronomers are predicting that a massive solar storm, much bigger in potential than the one that caused spectacular light shows on Earth earlier this month, is to strike our planet in 2012 with a force of 100 million hydrogen bombs. Several US media outlets have reported that NASA was warning the massive flare this month was just a precursor to a massive solar storm building that had the potential to wipe out the entire planet's power grid. Despite its rebuttal, NASA's been watching out for this storm since 2006 and reports from the US this week...

On Sunday, NASA's Solar Dynamics Observatory detected a complex magnetic eruption on the sun. The NASA Solar and Heliospheric Observatory (SOHO) also spotted a large coronal mass ejection (CME) The eruption happened around (3:50 am EST), the SDO detected a C3 class solar flare originating from a group of sunspots (called sunspot 1092). The flare itself was not that large, but the filament located about 70,000 miles away erupted at the same time. A filament is a large, bright feature extending outward from the Sun's surface, often in a loop shape. Filament is anchored to the Sun's surface in the...

OVER THE HORIZON: Something bright and active on the far side of the sun is about to turn toward Earth. Magnetic loops towering over the eastern limb herald its approach: NASA's Solar Dynamics Observatory took this picture during the early hours of July 26th. The bright glow revealed by SDO's extreme ultraviolet camera comes from million-degree plasma trapped by overlying magnetic fields. A sunspot is likely at the bottom of it all. Or maybe two sunspots... NASA's STEREO-B spacecraft is stationed over the sun's eastern limb, and it sees a pair of active regions approaching single file. The one peeking...

Scientists have identified a massive eruption from the sun in April that reached all the way to Earth and may be responsible for knocking out a satellite, creating a so-called "zombie satellite." The huge explosion of plasma and magnetic energy, called as a coronal mass ejection, occurred on April 3 and was observed by NASA's sun-watching STEREO spacecraft, according to the U.S. Naval Research Laboratory. The laboratory released new images of the solar storm last week. The solar storm appears to have disabled the Intelsat communications satellite Galaxy 15, NRL officials said. Galaxy 15 lost contact with its ground controllers...

US Navy Physicist warns of possibly 'several decades of crushing cold temperatures and global famine' By Retired U.S. Navy Physicist and Engineer James A. Marusek 2 Apr 09 – Excerpts: “The sun has gone very quiet as it transitions to Solar Cycle 24. “Since the current transition now exceeds 568 spotless days, it is becoming clear that sun has undergone a state change. It is now evident that the Grand Maxima state that has persisted during most of the 20th century has come to an abrupt end. “(The sun) might (1) revert to the old solar cycles or (2) the...
