The Vision for Space Exploration is a bold new course into the cosmos, a
journey that will return the space shuttle safely to flight , complete the
construction of the International Space Station, take humans back to the moon
and eventually to Mars and beyond. As the stars aged over billions of years, they
grew brighter and eventually swelled in size to become red giants.
If any planets orbited in these systems, the red giants would have
engulfed at least the inner ones.
Though the dust seen by Spitzer around the white dwarf is most likely the
remains of such a torn-up comet, there may be other explanations.

A space vehicle with a payload bay the size of a space shuttle could bring
back enough helium-3 to generate the electricity to satisfy the United
States' needs for a full year. The newest planetarium dome show transports audiences through time
and space to view the evolving universe and witness galactic events that
changed the course of life on Earth.
Astronomers believe white dwarfs are shrunken skeletons of stars that were
once similar to Earth's sun. Millions of
years later, the red giants shed their outer atmospheres, leaving behind white
dwarfs. They also occasionally crash into
planets , as comet Shoemaker-Levy 9 did when it plunged into Jupiter. One
possibility is a second wave of planets formed long after the death of the
star, leaving a dusty construction zone.

Only a few pounds of helium 3 are known to exist on Earth,
most the by-product of nuclear-weapons production. This doesn't happen on the earth
because our atmosphere and our magnetic field shield our planet from these

The show recreates encounters usually invisible to humankind. The show also outlines the consequences of the sun's
magnetic variability and the incessant barrage of small ionized particles in
the solar wind ricocheting off Earth's magnetic field creating other worldly
conditions called "space weather". Only distant outer planets and an orbiting
icy outpost of comets would have survived.

"The dust seen by Spitzer around G29-38 was probably generated relatively
