Awesome. I hope he gets to making one for Europe too, though.

Angry Fork said:This thread is depressing because of how little it feels like we're doing on the space front. Everything we're doing is from the comfort of earth =/. Present day space lovers were born in the wrong era =(. I envy those in the future who'll see Mars landing and beyond (unless we blow ourselves up before then).

Eventually the particles that currently reside in/on our body will be reabsorbed by the earth and they'll find their way into another being, and that life will have its chance at advancing its species, and so on. Eventually some particle that is currently housed in or on your body will find its way to another planet. Which means that while your current conscience may not 'witness' it, you'll be there anyway.

Not necessarily. Some particles have resided in one place for millions upon millions of years! While the general trend of particles in the universe is chaotic diffusion, some states are pretty 'final', like if your shit ends up in iron in a stable part of space. So there you are, floating in an iron core for uncountable years, eventually dying with the universe in some manner.PantherLotus said:Oh settle down.

I love this video of Buzz Aldrin punching that conspiracy nut in the face. 72 Years old, but one hell of a punch.
If I would have stepped on the moon, and people would say I'm a liar and a thief, I would punch them too.

Would you be blinded if you look at the sun in space? (with those astronaut visors)
And how close can you get to the sun and still be able to look at it without being blinded or burnt?
Kyaw said:You will be blinded without them though right?
The earth's atmosphere acts like the visors, doesn't it?
nah man, it's totally safe to look at the sun from the surface of Earth. You can stare at it for hours at a time without damaging your eyes. fight your instinct to squint or look away.KarmaCow said:...you shouldn't look directly at the Sun, even on Earth.
cluto said:I heard staring at the sun raises your sperm count.
Ethereal clouds of dust and gas are illuminated by stars in the giant elliptical galaxy Centaurus A, captured in unprecedented detail by the Hubble space telescope. The photograph was taken with Hubble's most sophisticated instrument, the Wide Field Camera 3. It combines images from multiple wavelengths to reveal a dusty region of the galaxy.
Visible as a bright jewel in southern skies, Centaurus A lies a mere 11m light years from Earth and has at its heart a supermassive black hole that weighs 55m times as much as the sun. The black hole drives powerful jets of particles to within a whisker of the speed of light, releasing intense bursts of radio waves and x-ray radiation.

cluto said:Hey, some of you guys probably remember that this image was posted a while ago. I swear I remember someone posting a super high res version (in .pdf format most likely), but I cannot find it anywhere. I would really love to print this image out, but this is the highest res version I can find, and it has a bunch of .jpg artifacts anyway, so it's useless.

It is widely accepted that there is a super massive black hole at the center of our galaxy (and at the center of most/all galaxies). We can't however see this back hole due to thick dust clouds along the galactic plane.lo escondido said:Isn't it a black hole? (don't know why it would be bright though) But that isn't a real picture of the milky way anyways since we can't take a picture of something we're inside of.

As for why it is bright, that has been confusing me for a while too. I thought black holes are, well, black, i.e. invisible. But I recently watched in interview with Micho Kaku (spelling?) who said if weren't for the dust clouds obscuring our view, then the black hole at the center of our galaxy would appear brighter than the full moon at night to the naked eye! That caught me off guard and I still don't know the explanation (didn't try to look it up)...
Perhaps it has to do with the massive amounts of matter (including nearby stars) that are being constantly sucked in by the black hole? All that tearing and compressing of matter and space time around the event horizon must be releasing insane amounts of energy (and thus glows?)... Also don't objects going into the black hole apprear (for a distant observer) to be continually slowing down as they approach the event horizon but never fully reach it (relativity)? Which might explain the intense brightness, as all that mass would appears to be accumilating in ever growing quantities around the black hole since an observer can never see something "go inside".
I wrote all that from bed on my phone as I struggle to sleep at 6 in the morning. Phone web browser doesn't support tabs so I can't look up any of that to verify it. So might all be wrong
Really layman's explanation: Because black holes emit a lot of radiation and stuff as they consume matter.Naked Snake said:It is widely accepted that there is a super massive black hole at the center of our galaxy (and at the center of most/all galaxies).
