| A DEPICTION BY AN ARTIST |
Mrs. P. said, "I looked through a telescope at an area of the sky that has a black hole. I was able to see a dark area with no light. That was the evidence to show that the black hole was there. We can't see a black hole, but we can see the area where the black hole exists."
Thanks to NASA's far-flung Voyager 1 spacecraft, now exploring the final frontier beyond our solar system, humanity can tune into the sounds of interstellar space.
Scientists announced today (Sept. 12) that Voyager 1 left the solar system in August 2012 after 35 years of spaceflight, making it the first craft ever to reach interstellar space. No other manmade object has ever travelled so far away from its home planet.
This artist's concept shows the general locations of NASA's two Voyager spacecraft. Voyager 1 (top) has sailed beyond our solar bubble into interstellar space, the space between stars. Its environment still feels the solar influence. Voyager 2 (bottom) is still exploring the outer layer of the solar bubble. Image released Sept. 12, 2013.

To mark the occasion, NASA unveiled the first Voyager 1 recording of the sound of interstellar space, offering the probe's strange, otherwordly take on its new frontier. The sounds are produced by the vibration of dense plasma, or ionized gas; they were captured by the probe's plasma wave instrument, NASA officials wrote in a video description.

Important Questions
We should be able to write full sentences to answer these questions:
1. Why are inner planets rocky and why are outer planets made of gases?
The answer given in class was: (send me your answer)
2. What is the life cycle of a star?
p. 117 has a sequence
"What will happen to the solar system when the sun runs out of fuel?"
3. What causes a neutron star to form?
(page 114)
ANSWER: Voyager was hitting PLASMA. Plasma was rubbing on the spacecraft and caused vibrations. You can read more here
