Where is Everybody?

 •  Filed under Space, Links

Last week my wife Jennifer was looking for something to read during her lunch break. She stumbled across this piece on reasons why we appear to be so alone in the universe. Read at your peril. The numbers are mind boggling.

As many stars as there are in our galaxy (100 – 400 billion), there are roughly an equal number of galaxies in the observable universe—so for every star in the colossal Milky Way, there’s a whole galaxy out there. All together, that comes out to the typically quoted range of between 1022 and 1024 total stars, which means that for every grain of sand on every beach on Earth, there are 10,000 stars out there.

The Vastness of Space

 •  Filed under Links, Space

It's stuff like this that just boggles my mind.

Compared with the overall vastness of space, the moon is very close to us: it's just 238,900 or so miles away. But compared with our daily experience, absolutely everything in space is absurdly far apart. In the gap between us and the moon, you could neatly slide in all seven of the other planets — with a bit of room to spare. That includes Saturn and Jupiter, which are about nine and 11 times as wide as Earth, respectively.

Flying Over Pluto

“These close-up images, showing the diversity of terrain on Pluto, demonstrate the power of our robotic planetary explorers to return intriguing data to scientists back here on planet Earth,” said John Grunsfeld, former astronaut and associate administrator for NASA’s Science Mission Directorate. “New Horizons thrilled us during the July flyby with the first close images of Pluto, and as the spacecraft transmits the treasure trove of images in its onboard memory back to us, we continue to be amazed by what we see."

Miniature Space

Tilt shifting is the effect used in photography to simulate a miniature scene, but I've never seen it done on such a scale with these tilt shifted photographs of galaxies and nebulae.

Black Holes & Clones

 •  Filed under Space, Science

The BBC earth mini-site aims to explain what happens when you fall into a black hole.

After all, the event horizon is not like a brick wall floating in space. It's an artefact of perspective. An observer who remains outside the black hole can't see through it, but that's not your problem. As far as you're concerned there is no horizon.

Sure, if the black hole were smaller you'd have a problem. The force of gravity would be much stronger at your feet than at your head, stretching you out like a piece of spaghetti. But lucky for you this is a big one, millions of times more massive than our Sun, so the forces that might spaghettify you are feeble enough to be ignored.

I had to read this a couple of times to get it. Well worth the time to read though!
