Top
10 Space Mysteries for 2003
The funny thing about discoveries is that they often produce new mysteries,
too. 2002 was no exception, as many remarkable space science findings
generated puzzling problems for astronomers to look into.
5
Great Cosmic Mysteries
This series of five
stories exploring the great unanswered questions of modern space science
ran as part of our Science Tuesday presentations in early 2002.
The
New Milky Way
12 March 2002: After a decade when other astronomical targets got more
attention, the Milky Way has come back into vogue as a hot research subject
in the new millennium, leading to a whole new picture of how the galaxy
formed, how unimaginably huge it is, and what it looks like from afar.
All
Galaxies to Become Ghosts, Frozen in Time and Space
12 December
2001: As if in a dream where we swam but could not reach the shore, the
universe likewise recedes as we study it, destined to disappear at the
whim of time, space and the laws of physics.
Astronomers
Compete to Find the Farthest Galaxies
11 September 2001: The most distant objects in the universe will likely
be spotted soon or may already have been detected by one of several telescopes
and could be waiting merely for astronomers to mine the existing data.
Cosmic
Cannon: How an Exploding Star Could Fry Earth
19 June 2001: Shooting out jets of energy or blobs of stuff the size of
Earth at nearly light-speed, exploding stars called supernovae may hold
more potential peril than anyone had ever imagined, according to a growing
suspicion among some researchers.
The
Universe: Still Boggling the Minds of 'Finite Creatures'
12 June 2001: How old is the universe? Does it have an edge? And, c'mon,
truthfully -- How could it all have begun in some "Big Bang" that originated
in a spot smaller than the dots under all these question marks? We've
got answers, to the extent that is possible.
Our
Tangled Universe:
How the First Galaxies Were Born
 22
May 2001: Were Sherlock Holmes a cosmologist, he might have said, "It's
filamentary, my dear Watson." And he might have gotten some arguements.
It's all about some new findings that support the theory of a spongy (or
web-like) early universe.
Moon
Helps Hunt for Mystery Particles
14 May 2001: A ubiquitous river of invisible cosmic particles may hold
vital clues to everything from black holes to missing matter to the origin
of the universe. But we won't even know if these particles exist until
if and when they are discovered. But finding them will require a really
big telescope. Maybe something as big as the Moon.
'Brane-Storm'
Challenges Part of Big Bang Theory
13 April 2001: Faster than you can say "Ekpyrotic Universe,"
a movement has taken hold -- albeit like fingers on a ledge of eternal
skepticism -- that would blow one of the basic tenets of the Big Bang
to smithereens.
'Groundbreaking' Discovery: First Direct
Observation of Dark Matter
22 March 2001: More than three dozen elusive white dwarf stars have been
found in a halo of objects surrounding our galaxy, marking the first direct
evidence for previously unseen "dark matter" and lending support
to a widely held theory that there is much more to the universe than meets
the eye.
