Solar storms can be far more powerful than previously thought. A new study has found evidence for the third known case of a massive solar storm in historical times. The researchers believe that society might not be sufficiently prepared if a similar event were to happen now.

The Earth's magnetic shield booms like a drum when it is hit by strong impulses, according to new research.

On Jan. 4, 2019, at 4:37 a.m. EST the CAPER-2 mission launched from Norway. The rocket flew through active aurora borealis, or northern lights, to study the waves that accelerate electrons into our atmosphere.

Climate change could have devastating effects on vulnerable residents in the Andes mountains and the Tibetan plateau, according to researchers who have been studying glaciers in those areas for decades.

Scientists have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the sun's past and future as well as whether solar activity plays a role in climate change.

New research describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space.

A new study has uncovered the history of bleaching on a reef in the epicenter of El Nino, revealing how some corals have been able to return after facing extreme conditions.

Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently.

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping.

School students have successfully identified sounds caused by a solar storm in the Earth's magnetic shield. The group of students identified a series of waves whose pitch decreased over the course of several days. They found that this event occurred after a Coronal Mass Ejection or 'solar storm' caused a great disturbance to Earth's space environment.

Pioneering new research has given a new perspective on the crucial role that 'natural factors' play in global warming.

Satellites are more likely to be at risk from high-speed solar wind than a major geomagnetic storm according to a new study.

Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research.

A new study isolates key mechanisms that cause El Niño events to differ. Researchers found that the complexity and irregular occurrence of El Niño and La Niña events can be traced back to the co-existence of two coupled atmosphere-ocean oscillations, with different spatial characteristics and different frequencies.

We know heatwaves over land have been increasing, but now new research reveals globally marine heatwaves have also been increasing in length, number and intensity over the past century. More intriguing still, this trend has accelerated markedly since 1982.

A major hurricane struck the islands of Hawai'i and Maui on Aug. 9, 1871, and wrought widespread destruction from Hilo to Lahaina. A recent study revealed how historical Hawaiian-language newspapers expand knowledge of this and other natural disasters of the past.

Ocean conditions off most of the US West Coast are returning roughly to average, after an extreme marine heat wave from about 2014 to 2016 disrupted the California Current Ecosystem and shifted many species beyond their traditional range, according to a new report from NOAA Fisheries' two marine laboratories on the West Coast. Some warm waters remain off the Pacific Northwest, however.

A new study reveals that strong El Nino events can cause significant ice loss in some Antarctic ice shelves while the opposite may occur during strong La Nina events.

Researchers have addressed an international environmental problem by developing a model that can predict how certain chemicals amplify the effects of pesticides and other chemical compounds. Pesticide expert hopes that it will make environmental legislation easier.
