16 super-Earths found including one that may have the ability to sustain life.

Somewhat interesting... the one that is most likely of any to sustain life is fairly close (in relative terms) at 35 light years away.

Dinosaur Bird Feathers found in Amber. John Hammond intrigued.

Nice. Was mildly surprised to see that the actor that played John Hammond is still kicking at 88

if an alien race is that violent AND is capable of harnessing the amount of energy required for intergalactic travel, it would have blown its own planet up long ago.

I'm glad we are funding studies with conclusions like "they will come to eat or enslave us."

wow. awesome.

it took them quite some time to release the findings from when they first saw this. makes me wonder what other, "unofficial" stuff they've found so far.

Rebooting the Cosmos: Is the Universe the Ultimate Computer?

Full 90-minute program: As computers become progressively faster and more powerful, they’ve gained the impressive capacity to simulate increasingly realistic environments. Which raises a question familiar to aficionados of The Matrix—might life and the world as we know it be a simulation on a super advanced computer? “Digital physicists” have developed this idea well beyond the sci-fi possibilities, suggesting a new scientific paradigm in which computation is not just a tool for approximating reality, but is also the basis of reality itself. In place of elementary particles, think bits; in place of fundamental laws of physics, think computer algorithms. But is this a viable approach? Is the universe the ultimate computer running some grand cosmic code? A discussion among the brightest minds in digital physics to explore math, computer science, theories of consciousness, the origin of life, and free will—and delve into a world of information that may underlie everything.

But who is the programmer?
I've often thought about this, that we may all just be computer code executing, or something like it. It was also on one of the through the wormhole episodes. Scientists do like to talk about particles having information associated with them.

Image

This image of the Crab Nebula combines visible light (green) and radio waves (red) emitted by the remnants of a cataclysmic supernova explosion in the year 1054, and the X-ray nebula (blue) created inside the optical nebula by a neutron star (the collapsed core of the massive star destroyed in the explosion).


Not really sure what this all means, but that's pretty spectacular.

Can't imagine what that supernova must have looked like 1000 years ago...would love to see something like that in my lifetime.

I'm trying to picture what something like that would look like by the naked eye here on earth. Does it look like the picture?

The Crab Nebula is NOT visible to the naked eye from here on Earth. With a pair of binoculars, you can definitely make it out faintly in Taurus. I've grabbed a few telescopic views of it and it's pretty dang cool.

The supernova that formed it was most definitely visible 1000 years ago. It was easily visible even during the day.
