This photo shows the size of our teeny weeny little Sun compared to a few other stars. From the excellent web page, "The Scala of the Universe 2".
A team of researchers have created this photograph showing the entanglement of photons. Business Insider has a nice little story about their work.
From NASA.gov: As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.
The conundrum is that the disk shouldn't be there, based on current astronomical theories. However, the unexpected presence of a disk so close to a black hole offers a unique opportunity to test Albert Einstein's theories of relativity.
I’ve seen five rattlesnakes since I moved to Colorado, four dead and one that was quite upset with me. As I was walking yesterday I wondered, can snakes see? Here’s an answer from animals.howstuffworks.com.
LiveScience.com adds this information: “With the exception of a few species that have adapted to daytime hunting, most snakes do not see well. Generally they can see shapes but not details. Snakes called pit vipers can see well at night by an amazing trick. Their pits (one on each side of the head) sense heat (infrared light) like night vision goggles. These pits, not eyes, actually are thought to render images of prey in the snakes’ brains.”
I remember when the only wind turbines I had ever seen were the ones off of I-65 in Indiana, part of an experiment at Purdue. Now there are over 59,000 of them. I’m not sure why the southeast isn’t participating, but this U.S. wind turbine database is cool.
