Evolution marches on, and sometimes its adorable

all-white-penguin

  Well, maybe not evolution per se, but the stuff of evolution, i.e., genetic diversity manifested as morphological variance, and this is a pretty cute example if indeed it’s a product of heritable genotype. Click image for the skinny on this adorable little guy from Nat’l Geo.

antarctic_vents

The thing about Antarctica is it’s cold. Really cold. As in an average temperature of about 15 F on the warmer coastline and even more frigid in the interior. So maybe it’s no surprise that warm seeps and hydrothermal vent communities in that neck of the woods would march to their own beat. That’s exactly …

The most magical time of the year

Solar noon marked voder the course of a single year as seen from the Urkraine. The figure is called an Analemma, featured on APoD

Believe me, if you grew up in Texas, where summer heat tops the century mark for weeks on end and even the morning lows offer little relief, you’d feel December was pretty damn magical. This month dawn and dusk stretch out, as the sun marches steadily to the Winter Solstice. The solstice was  a magical time for …

An amateur astronomer using a homemade 25 cm (10 inch) telescope has recorded an exquisite image of a nearby star and surrounding planetary disk. Beta Pictoris is 63 light-years away and resembles a slightly more massive, hotter version of our sun and primeval solar system in the early stages of planetary formation. The New Zealand star-gazer, named Rolf …
