Who: Marc J. Kuchner
What: Scientists looked through the Spitzer Space Telescope at a dead star far away.
When: February 21, 2007
Where: NASA's Goddard Space Flight Center in Greenbelt, Md.
Why:
To see what will happen to our sun and planet Earth in five billion
years and discovered something different from what they originally
thought.
My opinion:
My opinion on this article is to
expect the unexpected because the scientists thought that what they
were going to see while looking at the dead star through the Spitzer
Space Telescope was a bunch of extra dust that got pushed away from the
Helix nebula. Instead of it getting pushed away, the dust surrounded
the Helix nebula. Scientists found even older white dwarfs with dust
surrounding them, too. The scientists think that this is what will happen to our
star in five billion years when it breaks down because the dust
consisted of the same thing comets consist of. Our sun has comets that
orbit it just like the dust that is orbitting that white dwarf. This
article made me curious about what was going to happen to our solar
system once it dies out. I wondered if in five billion years there would even be an Earth because of the way we treat it. I also wondered if those other dead stars once had an Earth and solar system like ours. There could be a whole different kind
of life out there somewhere in space that we haven't discovered yet.
