1. Solar activity hits a new low
... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation".

10. Minnesota Lecture
... Most of the spirals discussed in the following are well-known starburst galaxies (M 82, NGC 253, etc.) In addition to their nuclear activity, which makes them so popular, the selected galaxies have several other phenomena in common, such as bars, gas outflow, and possibly nuclear rings. ... I compare the group of nearby starburst galaxies with distant ultra-luminous galaxies (Arp 220, NGC 6240, etc.), in which strong tidal interactions cause the radial gas inflow. ...
