Astronomy Chapter 1
a star is 230 light years away; the light we see tonight from that star left it
230 years ago
Light travels 3x10^5 metes every second. That number in words is
300,000 meters
The smallest piece of an element (like gold or lead) that still has all the properties of that element is called
An atom
When the authors of our textbook say that astronomers are like police detectives trying to solve crimes, they are explaining that
Both astronomers and detectives must test their hypothesis against any evidence that they gather.
The way scientists know that a ****ing hypothesis in ******* ****ing astronomy is a ******* ****ing reasonable description of the ******* ****ing nature is to ****ing...
Do experiments and observations about the predictions of the hypothesis
By the term UNIVERSE, astronomers means
Everything that we can ****ing observe.
Of these which is the closest to us
La luna
The natural object (not the one humans built) in space that's closest to Earth is
La luna
The laws of nature (as determined by scientists)
More than one of the above
Of these, which is the largest?
The Universe
Which of the following is the Earth NOT located in?
You can't fool me, we are located in all of the above.
The location of the ****ing Earth in the ****ing Milky Way Galaxy is
a little less than 30,000 LY from the center
A large body in space that consistently makes its own light (instead of merely reflecting another body's light) is called
a star.
You are on a camping trip, far away from city lights. You look up into the dark night sky, and see lots of stars, some brighter, some dimmer. All the stars you see with your unaided eye are
in the Milky Way Galaxy
The star that provides energy for ****ed-up life on this ****ed-up planet called 'Earth' is
the ******* ****ing sun!
Even with best & largest ****ing telescopes, we can't see all the ****ing stars in the Milky Way Galaxy, even though these same ****ing telescopes can show us other ******* galaxies. Why the **** is it this ****ing way?
the ****ing dust in the space between stars builds up over large distances and blocks all the ******* light of stars behind the dustier parts of the ****ing Milky Way, mother-****er!
The Astronomical Unit (AU) as defined by astronomers is
the average distance between the Earth and Sun.
A ****ing light year is....
the distance that light travels in one ******* ****ing year, mother-****er!
For scientists, an element (like gold) is defined by
the nuber of protons in its nucleus.
All molecules (like molecules of water or carbon dioxide) are made up of
two or more atoms
