I saw the moon and took a picture of it.
I wonder if it'd have been clearer at 200 mm, since my objective isn't really that good.
And Mars, but it's blurry as hell.
Anyone know the status of the prohibition of nuclear weapons in space? reading this thread reminded me of the orion project, wondered what the status was.
On Monday in general relativity we showed how the Schwarzschild solution to Einstein's equation gives gravitational potential, centrifugal potential, and a third term which goes as r[sup]3[/sup] that explains the precession of Mercury's perihelion. It was quite interesting.
I saw Venus and Mars and Jupiter tonight.
Too bad light pollution is making it limiting the visible stars at night.
Mercury isn't visible all times of the year
Jupiter is the best for observations, you can easily see the 4 moons with a pair of binoculars
I've never been so impressed by black holes. Sure they're incredibly massive, so massive that their gravity is so great that even light cannot escape them. That's pretty damn dope actually. But I'm fascinated by this:
There are five of these in heliocentric orbit. Five man-made planets in an orbit similar to our Earth's. Artifacts from the first (and potentially the only) interplanetary voyages ever undertaken by humans. And they're probably going to still be there billions of years after we will. Also they say USA on them, that's pretty cool. We as a nation used to be the shit.
My favorite thing about space are the great clusters of galaxies, it's just so amazing that each on in the Virgo super cluster is an entire galaxy each with around 500 billion stars.
Also I'm buying a table top telescope, Orion SkyScanner 100mm TableTop Reflector. It's cheap and it's pretty good quality if you want to look at planets and messier objects. And I really like that I can take it anywhere.
any thoughts on a better one at the same price?
I just found out that I will be able to do my masters within the Aerospace Engineering field even though I'm studying Computer Science and Engineering. It's still ~2 years until the day I make my choice, but knowing it right now is making me feel so damn happy.
And also the fact that there's so much crazy shit in space.
A star that has a surface rotational velocity of 1/7 the speed of light?
Giant clouds of antimatter?
Stars that have a surface temperature that you could survive at?
Hell, every fictional planet ever imagined probably exists in some fashion out there.
There are nowhere near enough hard sci-fi movies about realistic colonization efforts.
Aliums are sceery?
Don't get me wrong, I love and welcome and look forward to any further attempts with great excitement. I'm just saying that there is the possibility that those five objects will remain in a class of their own. Societies track record so far has been each one collapsed before it got to a point comparable to where we are now.
I think China would be down for a space race. If after the election, whoever's in office makes a great speech and we're officially off to other worlds again, and with meaningful pace, I think China would at least try and get in on that.
The thing about SLS and all the other is that it's all so long-term. You can read about all this in Dr. Neil Tyson's book 'Space Chronicles: Facing the Ultimate Frontier', but basically, what made the Apollo program what it was is the fact that it was immediate. It was we're going to the moon, and with a deadline that was only a few years out from the sitting president's potential term. That's crucial because what it means is that it's not like the Bush or Obama space plan where it's an unconfirmed plan with an unallocated budget to be managed by a future administration whose goals and concerns will most assuredly be very different.
So after this debacle of an election, whoever gets it needs to say we're going back to the moon by the end of the decade and do the other things, not because they are easy, but because they are hard, etc, but this time with permanence, and in preparation for manned missions to other worlds beyond our own. The gist I get from the book is that Dr. Tyson postulates that sending humans to worlds beyond our own, while seemingly impractical, directly benefits society in many ways, far more than robotic exploration. It elevates the consciousness of the people and motivates them to dream and think positively about the future because their awareness of the adventures and voyages of other people opens them up to new ideas. Just like in the Age of Discovery, when men were sailing ships to distant and foreign lands, it was an enlightened period. It also happens to supercharge an economy. This change in society as a whole and the space program itself then begins to change technology in unexpected and catastrophic ways. Every electronic device in existence today owes its existence to the Apollo program's effort to miniaturize computing to save weight.
AND the event horizon is a false singularity. Certain quantities seem to diverge as you reach the event horizon, but they disappear if your reference frame is free falling into black hole.
Either way here's a photograph I took of the moon last June, after a total lunar eclipse. It turned a nice redish color.
400mm, but on a full frame camera.
Here's a fascinatingly beautiful photograph I stumbled across;
It's Saturn back-lit by the sun.
You know, whenever I see the planets in CGI images or painted pictures I'm always like, "That's so amazing they look really cool", but when I see pictures of how they actually look like in space, these for example, they just look so incredibly surreal and awesome.
Guess the planet.
Well, it's in the URL.
But even if it wasn't, here's the clues. It's clearly a barycenter. It's also spatially close to the Earth Moon system, as evidenced by the clearly early photography, related to the fact that interplanetary missions hadn't flown very far at that point.
And I can think of only one barycenter in the general area of the Earth Moon system.
The probe MESSENGER leaving Earth. Same probe that took that photo.
