[UPDATED: Dec. 5, 2013 – see note, below] This thrilling, deep space video of comet ISON (aka the newest ‘comet of the Century’) passing Earth and Mercury on its way … [Read full article]
We’re trying to get more solar energy stories going here on Planetsave. To catch readers up, I’m doing a short series on the top 50 solar energy stories of 2013 so … [Read full article]
The Earth’s magnetic field, or magnetosphere, protects life down on the surface from excess radiation (in the form of high-energy particles and waves) that originate from the solar wind. But … [Read full article]
Two hundred thousand miles (322,000 km) above the earth, the Interstellar Boundary Explorer (IBEX) drifts in space, quietly “sniffing” the interstellar wind that continuously streams into our solar system from … [Read full article]
Active Region (AR) 1302 is slowly coming into position where it directly faces the Earth. The region contains a “behemoth” sunspot — several times larger than the Earth — named sunspot 1302.
The sunspot has already been the source of two ‘X-class’ solar flares (‘X’ signifying the most extreme known); the first, measuring an X1.4, on September 22, and the second, an X1.9, coming just three days later on Sept. 24. Are more X-class flares on the way, and on their way towards Earth?
This Spring has been pretty exciting for solar activity…Following the ending of the longest ‘solar minimum’ in more than a century, our sun’s activity (solar cycle 24) picked up considerably over the course of the month of May, culminating in an impressive M-2 class (medium size) solar flare and “spectacular” coronal mass ejection (CME) on June 7.
