Distant Cousins: Kepler-186f

Big Eyed Beans from Venus – Captain Beefheart and his Magic Band! Cool. Literally Comparable to Mars in effective temperature, bit larger than Earth, probably slightly more massive than Earth (mean density could be lower), atmosphere unknown. Might well have extensive surface regions with persistent liquid water.

Backreactions

A frightening fraction of my open tabs are some of Bee’s posts at Backreaction – so to save my browsers, I dump them here for further future perusal: Are irreproducible scientific results okay and just business as usual?

(the following is in part shamelessly cribbed from a colleague’s previous freshman seminar for our majors): Do you like stars and…

So, now you’re at university, and you’re thinking about heading for grad school … A seasonal revisit of some old rumblings* *NB: this discussion should not be construed to be anything but hypothetical ramblings, they do not reflect in any way the official position of any academic institution, department or graduate program, especially not the…

What should a high school student do to get on a track to become an astrophysicist?

Augmented Reality Layar at AAS

An interesting new twist for the 223rd meeting of the American Astronomical Society will be the “Augmented Reality” poster – an instantiation of the very rapidly growing augmented reality features appearing everywhere through smartphone apps or google glass. V838 Mon poster by Vogt et al will have a layar augmentation: using layar creator, tags are…

Although many moons have passed, we once again approach The Mighty iPod One, and we once again ask the impossible: Oh, Mighty iPod, is there indeed invasive terrestrial scum on Europa, transmitted through the mystery of lithopanspermia? Woosh goes the Mighty iPod. Woosh. The Covering: Peace On Earth/Little Drummer Boy – Bowie and Crosby The…
