Hubble’s Amazing Universe
1. Hubble orbits ____________ miles above the Earth, orbits the earth every 90 mins, it
weights 12 tones, and is as large as a __________________ ____________.
2. It only has a ________________ year life expectancy and was launched in 1990.
3. Stars evolve from clouds of _________________ and ________________.
4. The Eagle nebula is _______________ light years away, and the large tower on the
left is 4 light years high!
5. ________________ appear to be forming inside the EGGs (evaporative gaseous
globules)!
6. The orion nebula is 1500 light yearss from earth, and demonstrates protoplanetary
discs, which triggers nuclear fusion.
7. In 2005, the Corina nebula was revealed. The data comes back in ________________
and ____________________, and gasses are assigned colors. Blue is ___________, and
green is ___________________.
8. This region is _____________ light years across!
9. Hubble even showed a star about to die! As a star runs out of ______________, it
expands, and it is released into space.
10. Someday, our own star will expand and engulf the earth. Luckily, this will happen in
________________billion years.
11. Some stars are 100 times more massive that our sun. When a star explodes, it’s
called a _____________________. Our sun will not go supernova because it’s not
________________ enough.
12. The _________________ nebula is in our Milky Way galaxy, and exploded in 1054.
It was so bright, Chinese astronomers could see it during the day!
13. An exploding star spreads its materials out to be used again. _________________ in
your blood and _______________ in wedding rings is created in a super nova!
14. Eta Carina is ______________ solar masses, is young, but unstable. Its explosion
will be as bright as the full moon, and cast shadows at night!
15. Hubble provided conclusive proof that a _____________ ______________ existed.
16. The gravitational field around a Black Hole is so large, that _________________
cannot even escape.
17. Most stars revolve at relatively slow speeds, but Hubble detected ones going too
_______________. They must be going around a BH.
18. Hubble provided actual evidence that ______________ collide with other planets.
The impact cause gas to go 300,000 km into space, and generated extremely high
temperatures.
19. It took Hubble ___________ days to expose the Hubble Deep Field image. Every
smudge of light is a _______________ containing billions of stars.
20. It seems that there is ______________ more dark matter than physical matter in the
universe. But there is still 2/3 missing!
21. Hubble has also shown evidence that something called ____________
_______________ exists. This is what is forcing the edges of the universe to
___________________ away from us.
22. We’re hoping that after Hubble burns up into the Earth’s atmosphere, it will plunge
into the __________________ __________________.
23. The replacement of Hubble will be the ________________telescope, and will orbit
outside the moon. It has a chance of taking a direct image of another
_________________ going around another star outside our solar system!
