Our world today would not manage to survive without technology, whether it is as basic as electricity or as advanced as the Internet. Businesses all across the world use these to get work done on a regular basis. So can solar storms really knock all of these out? What if our entire globe went dark, ...
What do you feel when you see an aurora, and what does this have to do with solar activity? Otherwise known as the northern or southern lights, an aurora is light emitted by upper atmospheric particles as they interact with energized ones from the magnetosphere. It’s an awe-inspiring and otherworldly event that those living at ...
The high efficiency, light weight, and flexibility of the latest solar cell technology mean photovoltaics could provide all the power needed for an extended mission to Mars, or even a permanent settlement there, according to a new analysis by scientists at the University of California, Berkeley. Most scientists and engineers who’ve thought about the logistics ...
Advancements in human technology have already pushed into the endless frontiers of the Earth and those beyond it. Almost all fields and human disciplines benefit from technology, and it would be safe to assert that human beings are hugely technology-dependent. But we are also hugely vulnerable to disruptive forces like a Carrington event, which is caused ...
Having a large quantity of aerosol particles in the atmosphere may increase the duration of large storm clouds by delaying rainfall, giving the clouds time to grow larger and live longer. Aerosols will produce more extreme storms when the rain finally falls. The research from the University of Texas at Austin, which was published in ...
The NASA/ESA Hubble Space Telescope has completed its annual grand tour of the outer Solar System. This is the realm of the giant planets — Jupiter, Saturn, Uranus, and Neptune — extending as far as 30 times the distance between Earth and the Sun. Unlike the rocky terrestrial planets like Earth and Mars that huddle close to ...
On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s ice-encrusted moon Ganymede than any spacecraft in more than two decades. Less than a day later, Juno made its 34th flyby of Jupiter, racing over its roiling atmosphere from pole to pole in less than three hours. Using the spacecraft’s JunoCam imager, the mission team has put ...
A new study led by the University of Hawai‘i (UH) at Mānoa has helped refine our understanding of the amount of hydrogen, helium, and other elements present in violent outbursts from the Sun and other types of solar “wind,” a stream of ionized atoms ejected from the Sun. Coronal mass ejections (CME) are giant plasma bursts that ...
Just released first images from the National Science Foundation’s Daniel K. Inouye Solar Telescope reveal unprecedented detail of the Sun’s surface and preview the world-class products to come from this preeminent 4-meter solar telescope. NSF’s Inouye Solar Telescope, on the summit of Haleakala, Maui, in Hawai‘i, will enable a new era of solar science and ...
Data from ESA’s Cluster mission has provided a recording of the eerie “Earth’s magnetic song” that Earth sings when it is hit by a solar storm. The song comes from waves that are generated in the Earth’s magnetic field by the collision of the storm. The storm itself is the eruption of electrically charged particles ...
