//Into The Universe//

[Maestro]

same here! its one of my favorite classes i've taken so far...

dammit everyone who has taken the class has said that. I've had multiple opportunities to take the class but I always shrugged it off.

I'll have to try to fit it in my schedule in the spring I guess.......

Met too!

Intro to Astronomy was easily one of the most interesting classes I took in college.

Yeah completely recommend it, as long as you have a professor that know's what he or she is talking about, it's a great class.

[Skunk]

I'm taking an Intro to Astronomy class right now too. I love astronomy, but I'm not enjoying the class too much. The teacher sucks at teaching and is annoying, but luckily I already understand most of the stuff being taught in the class. Plus most of the kids in the class are ****ing retarded. So I basically just day dream in class. Wished the teacher was better...

Astronomy was an awesome class, but sht son it got difficult at times with parallax angles

What were some of the things you learned about? The astronomy class I took was a high school course so i'm interested in the differences. In my class it first talked about Aristotle's and Ptolemy's geocentric universes and when and who invented the first telescope and some more around that area, Tycho Brahe and Johannes Keplers, and Galileo, and everything that contributed / studied. newtons law, light year, celestial sphere, constellations of stars, describing the different telescopes out there and what are used, for example reflecting and refracting, ummmm all the types of radiation, seasonal changes, how clocks work, properties of the sun and all the other planets, Jovian and terrestrial, stellar distances, stellar luminosity, classifying stars, HR diagram, main sequence, high-mass and low-mass stars, stellar evolution, star clusters, galaxys, dark matter, dark energy, and a lot of other stuff.

Is that some of the stuff you learned also in the college course? Currently taking a more advanced class.

More tidbits on the universe.

-There are more stars than all of the grains of sand on earth.

-Stars come in different colors; hot stars give off blue light, and the cooler stars give off red light.

-All of the stars comprising the Milky Way galaxy revolve around the center of the galaxy once every 200 million years or so.

-Our galaxy has approximately 250 billion stars and it is estimated by astronomers that there are 100 billion other galaxies in the universe.

-A galaxy of typical size, about 100 billion suns produces less energy than a single Quasar.

-A Comet's tail always points away from the sun.

-Pulsar is a small star made up of neutrons so densely packed together that if one the size of a silver dollar landed on earth, it would weigh approximately 100 million tons.

I thought about this....under some "influence" yesterday while watching Through the Wormhole about time travel. They said that it wasn't possible unless there was a time machine, at which point once one was made, we could travel back to then only. I thought this was a little short sided.

All we would need to go back in time is to find an alien civilization that has discovered time travel. Since we are very young, it's plausible that someone somewhere in the universe has discovered time travel already. To find this probability, you'd have to modify the Drake Equation to civilizations who could have developed time travel and the probability that we will discover them. OK misc mathematicians, go to work.

clarify:

Sand on earth's surface?

Sand on the beach?

Sand under water count as well?

What about different soil types?

I think its sand on beaches

still an insane amount son

Its every grain of sand on the entire Earth,But then again its just speculation.I personally think the number of stars in the universe are so unimaginably high that you cant even compare it to anything.

Oh wait, even deserts?


sheeeeeet neegah


I also think its impossible to 'compare' because the human brain just cant picture quantities of that size, especially with something like stars.


'A billion squillion stars' just means nothing. You cant picture you can only appreciate its a huge number.


You really need a universe zoom out vid to make any sense of it

[MontelWilliams]

yeah it's mind blowing how many star there are

250 billion alone in our galaxy

and there are 100 billion more galaxies each which probably hundreds of billions of stars in them

[HereToLul]

God, I love this stuff so much, it mind fukks the hell out of me every single time.

Which is exactly why I want to major in physics, possible concentration in astronomy?

I have no idea what I should do, particle physics, theoretical physics, astrophysics, it's all so CRAZY.

Just read a book on string theory that completely blew my mind too. So much potential to describe the universe on scales that were previously unimaginable.

[styken]

I have reading about this stuff since I have been very little. And still when I see images from the deep universe and facts about space I get a strange feeling in my stomach.

Two years ago Axel Mellinger went on a mission. He set out to create a massive photographic panorama of all the stars in the night sky. He is now finished -- having created an image with something like 25 million stars in it.

you can zoom and pan around, pretty sweet.

And this is what.....? not even a quarter of a percentage of the stars in ouw own galaxy:?

Done



For future reference, all you need to do is put [ youtube ] [ /youtube ] (without the spaces both in between the brackets and in the brackets) and then the combination of letters and numbers, in this case a15KgyXBX24, after the = sign in the youtube url in between the blocks.

Hope that made sense (or just quote my post to figure out what I meant).

some pics of our local star!

NASA's twin STEREO spacecraft caught this image of a comet impacting the sun. The comet apparently survived the intense heat of the sun's outer atmosphere — called the corona — and disappeared in the chromosphere, which is a thin layer of plasma found between the visible surface of the sun and the corona.

A full-disk multiwavelength extreme ultraviolet image of the sun taken by the Solar Dynamics Observatory on March 30, 2010. This is one of the 1st images released from the new probe. False colors trace different gas temperatures. Reds are relatively cool (about 60,000 Kelvin, or 107,540 F); blues and greens are hotter (greater than 1 million Kelvin, or 1,799,540 F).

A solar tsunami seen by the twin STEREO spacecraft. A movie showing this event helped convince scientists that this phenomenon is real, and not a visual illusion

[Maestro]

When do we see Haileys Comet again?

lets see, If I recall, he last time Haileys comet was visible was in the 1970's and it only comes around every 80 years so..... somewhere along the lines of 2050......

I'm assuming it's speculative, but you get the general idea. Even if it were only beach sand, just try and imagine how many grains only a mile of beach would contain.

Universe is the truth and in universe you can found Everthing in this world.
The Universe is commonly defined as the totality of everything that exists, including all physical matter and energy, the planets, stars, galaxies, and the contents of intergalactic space, although this usage may differ with the context. The term Universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or nature.

The Story of Everything

I don't know about you guys,But the music at the intro of this series is awesome, Somehow it just adds to the mysteries of the cosmos. It's hard to explain, But i get an awesome feeling when i hear it(no homo).

Last time was 1986. next time we will see it is 2061.

[KillDowzer]

Last time was 1986. next time we will see it is 2061.

I rememeber seeing this when I was like 15...I was born in 86, and I think it left like 10 years ago?


Either way, I wish I could go back to it now and see it with a whole new perspective!

Prepare to be humbled.

Even the narrator in the video seems extremely amazed.
