Laniakea - Immeasurable Heaven
Superclusters. Sometimes science blows my mind.
Excerpted from the latest issue of Nature:
"The supercluster of galaxies that includes the Milky Way is 100 times bigger in volume and mass than previously thought, a team of astronomers says. They have mapped the enormous region and given it the name Laniakea — Hawaiian for 'immeasurable heaven'.
Galaxies tend to huddle in groups called clusters; regions where these clusters are densely packed are known as superclusters. But the definition of these massive cosmic structures is vague.
The new study, published in Nature1, describes a novel way to define where one supercluster ends and another begins. A team led by Brent Tully, an astronomer at the University of Hawaii in Honolulu, charted the motions of galaxies to infer the gravitational landscape of the local Universe, and redraw its map."

Who's Your Daddy?
While driving into Manhattan yesterday on approach to the Willis Avenue Bridge, we spied this Who's Your Daddy? truck.
I understand the purpose and merits of DNA testing. What caught my attention was the truck's concrete block, prison-like paint job and illicit graffiti-style branding. Not sure this look is going to attract or entrap daddies who have otherwise escaped paternal responsibilities.
See related story: With genetic testing, I gave my parents the gift of divorce.
