NASA’s Parker Solar Probe (PSP) has flown close enough to the sun to detect the fine structure of the solar wind close to where it is generated at the sun’s surface, revealing details that are lost as the wind exits the corona as a uniform blast of charged particles.

It’s like seeing jets of water emanating from a showerhead through the blast of water hitting you in the face.

In a paper to be published in the journal Nature, a team of scientists led by Stuart D...

Is Earth slowly heading for a new ice age? Looking at the decreasing number of sunspots, it may seem that we are entering a nearly spotless solar cycle which could result in lower temperatures for decades. “The solar cycle is starting to decline. Now we have less active regions visible on the sun’s disk,” Yaireska M. Collado-Vega, a space weather forecaster at NASA’s Goddard Space Flight Center

Maunder Minimum is also known as the “prolonged sunspot minimum”, which was a period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time.

But does it really mean a colder climate for our planet in the near future? In 1645, the so-called Maunder Minimum period started, when there were almost no sunspots...
