. A number of NASA instruments captured detailed images of this coronal mass ejection (CME) on August 31, 2012. Although CMEs can damage sensitive technological systems, this one just struck a glancing blow to Earth's atmosphere. New research has identified quasi-annual variations in solar activity, which may help experts better forecast CMEs and potentially damaging space weathers. NASA Goddard Space Flight Center

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...
