There’s a lot of evidence mounting that solar cycle 25 will usher in a new grand solar minimum. Since about October 2005, when the sun’s magnetic activity went into a sharp fall, solar activity has been markedly lower, with solar cycle 24 being the lowest in over 100 years. Cycle 24 is part of a…
UNH researchers find space radiation is increasingly more hazardous From the UNIVERSITY OF NEW HAMPSHIRE DURHAM, N.H. – It might sound like something from a science fiction plot – astronauts traveling into deep space being bombarded by cosmic rays – but radiation exposure is science fact. As future missions look to travel back to the…
NASA Powers on New Instrument Staring at the Sun NASA has powered on its latest space payload to continue long-term measurements of the Sun’s incoming energy. Total and Spectral solar Irradiance Sensor (TSIS-1), installed on the International Space Station, became fully operational with all instruments collecting science data as of this March. “TSIS-1 extends a long data record that…
By Javier So, you still don’t believe small changes in solar activity can significantly affect climate? You know a very cold period during the Little Ice Age coincided with the Maunder Minimum, but you have heard that the Little Ice Age could have had other causes, like volcanoes. You have been told repeatedly that since…
UPDATE: 3/13/18 After review of comments, data sources, and the article itself, I have concluded that because some old and faulty data was used in the article, the premise and conclusions are not accurate, and therefore this article should be ignored due to the use of the faulty data. If at such time the article is…
The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the Sun — an effort made possible only by combining data from three NASA satellites to produce a much more robust mapping of a CME than any one could do alone.…
Guest essay by David Archibald’ Many good things come to an end and that includes the Modern Warm Period. Mild winters and early springs are now spoken of in the past tense. The peak of the Modern Warm Period was 2006 as shown by the oceanic lead indicator, the Gulf Stream, also called the North Atlantic…
