APOD: Palomar 12 (2015 Feb 19) Image Credit: ESA/Hubble, NASA http://apod.nasa.gov/apod/ap150219.html Explanation: Palomar 12 was not born here. The stars of the globular cluster, first identified in the Palomar Sky Survey, are younger than those in other globular star clusters that roam the halo of our Milky Way Galaxy. Palomar 12's position in our galaxy and measured motion suggest its home was once the Sagittarius Dwarf Elliptical Galaxy, a small satellite of the Milky Way. Disrupted by gravitational tides during close encounters the satellite galaxy has lost its stars to the larger Milky Way. Now part of the Milky Way's halo, the tidal capture of Palomar 12 likely took place some 1.7 billion years ago. Seen behind spiky foreground stars in the sharp Hubble image, Palomar 12 spans nearly 60 light-years. It lies about 60,000 light-years away, toward the constellation Capricornus. http://www.spacetelescope.org http://www.nasa.gov/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=150219 #APOD

OK, don't read this article about passive-aggressive behaviour. Honestly, it's fine

Many people encounter passive aggressive-behaviour on a regular basis. Many people even use it, perhaps unknowingly. How can something seemingly self-contradicting become so common?
