Inspiration & Wonders

Regarding the recent NASA Kepler discovery of what is being dubbed the closest “Earth-like” or “Earth twin” planet…

"This planet Kepler-186f orbits a star that’s cooler and dimmer than the sun. So while we may have found a planet that’s the same size as Earth, and receives the same amount of energy to what Earth receives, it orbits a very different star. So, perhaps, instead of an Earth twin, we have discovered an Earth cousin," said NASA Ames Research Scientist Thomas Barclay, of BAERI.

Not to downplay this hype, however. There’s no mistaking it…THIS IS A MAJOR MOMENT IN HUMAN HISTORY.

Astronomers have discovered planets that reside in the Goldilocks or Habitable Zone of solar systems outside of our own. This, however, is the first confirmed find of a planet as close in size (10% larger) to that of Earth.

"This is the best case for a habitable planet yet found. The results are absolutely rock solid. The planet itself may not be [rocky], but I’d bet my house on it. In any case, it’s a gem," Geoff Marcy, Astronomer at the University of California Berkeley told Space.com.

Kepler-186f’s potential for liquid water and perhaps, life, is what make its existence that much more intriguing. [view larger]

"Some people call these habitable planets, which of course we have no idea if they are, we simply know that they are in the habitable zone, and that is the best place to start looking for habitable planets," San Francisco State University astronomer and study co-author Stephen Kane said in a statement to Space.com.

"The four companion planets — Kepler-186b, Kepler-186c, Kepler-186d and Kepler-186e — whiz around their sun every four, seven, 13 and 22 days, respectively, making them too hot for life as we know it. These four inner planets all measure less than 1.5 times the size of Earth," noted in an official statement from NASA.

Geoff Marcy said, "This planet is modestly illuminated by its host star, a red dwarf. This planet basks in an orange-red glow from that star, much [like what] we enjoy at sunset."


Kepler-186f is 1 of 5 planets around its host star, which is a red dwarf, taking 130 days to orbit. As seen in the comparison-worthy artistic rendering above, Kepler-186f and our Earth would share similar views at dawn and dusk.


Whether or not Kepler-186f does contain life, one thing is for certain, there’s a whole lot more space to explore. If Carl were here to share in these continued findings, I believe he’d revert to a self-quoted suggestion from his novel-turned-motion-picture, Contact

“The universe is a pretty big place. If it is just us, seems like an awful waste of space.”

Stay curious. This is just the beginning.

First Track on Incongruent: “I Fucking Love Science.” I think this will also be the first music video…if all goes according to plan.

Obviously, this is the explicit version. If you like it please share! And high five to Rob Scallon for that SICK DRUM SOLO!

God I’m excited about this.

So proud of Hank’s excellent new album.

Eyes: The Windows to Your Health

Your eyes are tiny spheres of wonder. A doctor can find warning signs of high blood pressure, diabetes, and a whole range of other systemic health issues, just by examining your eyes. Ophthalmologist Neal Adams explains why the eye’s tissues and blood vessels make such a good barometer for wellness.

Consider that you can see less than 1% of the electromagnetic spectrum and hear less than 1% of the acoustic spectrum. As you read this, you are traveling at 220 km/sec across the galaxy. 90% of the cells in your body carry their own microbial DNA and are not ‘you’. The atoms in your body are 99.9999999999999999% empty space and none of them are the ones you were born with, but they all originated in the belly of a star. Human beings have 46 chromosomes, 2 less than the common potato. The existence of the rainbow depends on the conical photoreceptors in your eyes; to animals without cones, the rainbow does not exist. So you don’t just look at a rainbow, you create it. This is pretty amazing, especially considering that all the beautiful colors you see represent less than 1% of the electromagnetic spectrum.
