Brett Smith for redOrbit.com - Your Universe Online Our Sun is constantly cycling between periods of low activity and high activity – known as solar minimum and solar maximum, or Solar Max, respectively. In 2008 and 2009, NASA’s solar experts reported they were surprised to see the Sun descend into one of its deepest solar minimums in recorded history. But now, NASA observers are saying that the solar minimum is almost over. [ Watch the Video: ScienceCasts: Solar Mini-Max ]...

Twin Peaks For Solar Cycle?
2013-03-02 07:29:34

redOrbit Staff & Wire Reports - Your Universe Online While 2013 is supposed to be the year of Solar Max - the peak of the 11-year sunspot cycle - the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks. According to NASA, sunspot numbers during the months of January and February 2013 were well below values recorded back in 2011. Furthermore, they report that...

Comet Corpses In The Solar Wind
2012-01-21 04:13:51

[ Watch the Video ] A paper published in the Jan. 20th issue of Science raises an intriguing new possibility for astronomers: unearthing comet corpses in the solar wind.  The new research is based on dramatic images of a comet disintegrating in the sun's atmosphere last July. Comet Lovejoy grabbed headlines in Dec. 2011 when it plunged into the sun's atmosphere and emerged again relatively intact.  But it was not the first comet to graze the sun. Last summer a smaller comet...

Last week, on Feb. 11th, the Solar Dynamics Observatory (SDO) lifted off from Cape Canaveral on a five-year mission to study the sun. Researchers have called the advanced spacecraft the "crown jewel" of NASA's heliophysics fleet. SDO will beam back IMAX-quality images of solar explosions and peer beneath the stellar surface to see the sun's magnetic dynamo in action. SDO is designed to amaze"”and it got off to a good start. "The observatory did something amazing before it even left the...

The sunspot cycle is behaving a little like the stock market. Just when you think it has hit bottom, it goes even lower. 2008 was a bear. There were no sunspots observed on 266 of the year's 366 days (73%). To find a year with more blank suns, you have to go all the way back to 1913, which had 311 spotless days: plot. Prompted by these numbers, some observers suggested that the solar cycle had hit bottom in 2008. Maybe not. Sunspot counts for 2009 have dropped even lower. As of March 31st,...

Astronomers who count sunspots have announced that 2008 is now the "blankest year" of the Space Age. As of Sept. 27, 2008, the sun had been blank, i.e., had no visible sunspots, on 200 days of the year. To find a year with more blank suns, you have to go back to 1954, three years before the launch of Sputnik, when the sun was blank 241 times. "Sunspot counts are at a 50-year low," says solar physicist David Hathaway of the NASA Marshall Space Flight Center. "We're experiencing a deep minimum...
