A scientist who claims waning solar activity in the next 15 years will trigger what some are calling a mini ice age has revived talk about the effects of man-made versus natural disruptors to Earth's ...

A sunspot is a relatively dark, sharply defined region on the solar disc – marked by an umbra, dark area, which is 2000 degrees cooler than the effective photospheric temperature. The average diameter ...

Aurora records in royal chronicles from Korea show that during the 'Maunder Minimum' between 1645 and 1715, the sun's solar cycles became several years shorter than they are today. When you purchase ...

The Northern Lights are normally seen in various high-latitude parts of the world, including polar regions and in the skies over Britain, but according to new research from the University of Reading, ...

In 1645, something strange happened with our sun. Galileo was one of the first astronomers to document temporary blemishes on the solar surface, called “sunspots.” But in the mid 17th century they ...

A new ice age is not actually coming. But you wouldn't know that based on headlines from places like The Telegraph. The "reasoning" behind the headlines is that a new study suggests the Sun is headed ...

The Sun's activity is at its lowest for 100 years, scientists have warned. They say the conditions are eerily similar to those before the Maunder Minimum, a time in 1645 when a mini ice age hit, ...

With each passing season, the weather seems stranger and more extreme. Who can argue with a sudden outbreak of the “polar vortex” phenomenon; unprecedented winter drought in California; and summer ...

A relatively quiet stretch for the sun in recent years does not necessarily herald an impending solar activity low of historic proportions, a new study reports. The sun was quiescent from 2005 to 2010 ...
