Black Holes and Astronomical Distances.

1.] 1. Saturn.

  • In visible light it looked like it does in every picture you see of it.
  • In radio waves it was a red circle with blue rings.
  • In x-rays you couldn't really tell what it was anymore, it just had white blotches where the planet was in normal view with other colors blotched around it.


2. NGC 7027 (planetary nebula).

  • In visible light, it looks kind of like when you put little drops of dye into watr and watch it swirl itself around. Its purplish in the midde with yellow, purple, then red surrounding it.
  • In radio waves it has a yellow center with two red spots in it lined with green then blue.
  • In x-rays it kind of looks like fire with red, yellow, and oranges mixed.

3. M33 (extragalactic binaries).

  • In visible light it looks like a swirled star cluster.
  • In radio waves it looks like a swirl of reds and yellows, like a circle of fire.
  • In x-rays it looks like christmas tree lights, all different colors with a large bright white star in the middle.

4. Milky Way Center.

  • In visible light it looks like the typically remake of the night sky. stars everywhere.
  • In radio waves it has a red center with yellows and greens surrounding it and a blue outline that sort of runs further from the center in one spot.
  • In x-rays it looks like there's blue and reddish smoke surrounding a white cluster of dots.

5. The Crab Nebula.

  • In visible light it looks kind of like green smoke with yellowish sand falling around it. It reminds me of the toys where you drag the lead ovre the guys face to give him hair in certain places.
  • In radio waves it looks like white smoke swirling with a tealish smoke.
  • In x-rays it kind of looks like when you have perfect timing to capture the picture of a drop of water hitting a pool of water and you see it spray up, except its kind of surrounded by dark blue smoke.

2.] 1. Cygnus-X1.

To leave the earth's gravitational pull you had to gain more speed and go to 25,000 mph, then you had to gain more speed to get to pluto from the moon by getting 1,000 billion times more energy, then you had to gain ten million times more energy to make it to Cygnus-X1 without it taking a forever. When I got to it, it was a black hole that looked just like it was a black planet with different shades of blue rings and it had a long trail of what looked like miny stars but when i read about it it said it was gas being sucked from a nearby star that orbits it.

2. Andromeda

To leave the earth's gravity you had to go 25,000 mph, then you had to get 1,000 billion times more energy to make it to Pluto, then you had to gain 100 million times more energy to get to the edge of our galaxy, and then it took 100 times more energy to make it to Andromeda. The galaxy is a black hole that has stars swirling around it that get sucked up by it. Scientists found that the black hole is thirty million times heavier than our sun.

3.]

  • How many black holes are there? There's so many, it's impossible to count.
  • What happens when two black holes collide? There gravity drags them together and they form one big black hole.
  • Do black holes live forever? Due to research, we know that they evaporate.

What I want to learn in Global Science.

I signed up for global science because i love the night sky. Stars are way pretty. I figured, if i thought they were pretty I'd probably think that this class would be good for me. No one likes being in a class they hate the subject of. Plus I'm curious about our universe. What all is in it and how it got there.

I did this assignment once, but i guess my blog didn't save or something. But here ya go ! =]
