When It Comes to Solar Storms, We Don t Even Know How Bad It Might GetJohn Matson
Previously, NASA’sParker Solar Probefound thatthese switchbackswere common throughout the solar wind. Parker, which became the first craft toenter the Sun’s magnetic atmospherein 2021, allowed scientists to determine that switchbacks become more distinct and more powerful close to the Sun. Up to...
Common symptoms include a fever, a dry cough and tiredness but you may experience a loss of taste or smell, a headache, a sore throat, aches and pains, nasal congestion, red eyes, diarrhoea, or a skin rash. If you have any of these symptoms, even if they are mild, you...
This week has seen one of the most dramatic solar storms in decades, leading toviews of auroras seen around the worldas charged particles from the sun interacted with Earth’s atmosphere. But the events weren’t only notable for the gorgeous colors seen in the sky — they are also a way...
These planetary auroras help scientists study space weather across the solar system and better understand how magnetic fields and solar activity interact on different worlds. Common northern lights questions answered by an aurora scientist We asked Dr. Elizabeth MacDonald a few frequently asked questions...
Whether you are a casual observer who simply appreciates the beauty of the heavens, or a serious, science-oriented observer, the night sky has plenty to offer. On the next page, we'll learn about some common telescope features. Telescope Features Once you have decided that you want to ...
Historically, large solar flares and geomagnetic storms are more common in the declining phase after solar maximum. For instance, Solar Cycle 24 saw its largest solar flares (X13.3 and X11.9) three years after its 2014 maximum, in 2017. As of mid-December 2024, the strongest solar flare...
Devastating floods are becoming more and more common around the world. The warming climate is leading to heavier rainfall, but could the way that cities are growing be making things worse? Could we design cities in a different way to reduce the risk of flooding? 毁灭性的洪水在世界各地变得越来...
To really stem the emission of greenhouse gases, we need to developnon-fossil fuel energy sources.Hydro-electric power,solar power,hydrogen enginesandfuel cellscould all create big cuts in greenhouse gases if they were to become more common. ...
