to believe in life on
other planets compared to non-churchgoers, 46% vs. Republicans
* No filibuster here -- given the margin of error, Democrats and
Republicans are equally
likely to believe in life on other planets
For those that do believe that life exists on
other planets, what would ET
be like?
* 7 out of 10 Americans think the intelligent
life forms on other planets
would be similar to humans
* 8 out of 10 Americans think
it is likely that the intelligent life forms
on other planets are more advanced than us
* 7 out of 10 Americans think it is likely that these life forms have the

to travel through space
* 7 out of 10 Americans think that these life forms have the technology

Should we respond if ET makes contact?
* 90% of Americans who believe life exists think we should communicate

detection of light from alien worlds, by observing
the warm infrared glows of
two other previously detected "Hot Jupiter" planets, designated HD 209458b

temperature of the

light emitted directly from the
planet. The discovery of far-reaching
explosive activity, due to giant central black holes in these
old galaxies,
was a surprise to astronomers. Contrary to expectations, they found the
distribution
of the multimillion-degree gas in these galaxies differed
markedly from that of the stars.
