After a
ten-year-long flight, the European Space Agency's (ESA) Rosetta spacecraft
entered into orbit around a comet. It will soon attempt to actually land a
probe on the comet's surface. Though data-gathering has only just begun, the
comet is already divulging secrets.
ESA's Director General
Jean-Jacques Dordain told ESA, "Europe's Rosetta is now the first
spacecraft in history to rendezvous with a comet, a major highlight in
exploring our origins. Discoveries can start."
...Could the
secrets of this comet's structure, composition and behavior really supply
answers to such grand questions?...
...If it's
really billions of years old, why isn't this comet old, cold, and dead—why does
it exist at all? Rosetta's investigation has not yet entered full swing, and
already reveals the comet as looking young, warm, and alive.
No wonder Matt Taylor, ESA's Rosetta project scientist said, "Our
first clear views of the comet have given us plenty to think about." (Emphasis added)

RULES OF THE ROAD:
1)The Names and Titles of God our Father and Jesus Christ our Savior will be respected at all times.
2) Discussion is encouraged, however, respect for other people and their opinions is the rule---play nice.
3) No profanity, allusions, innuendos or just plain nastiness will be tolerated. Decency WILL prevail.
This is MY house and YOU are a guest here and differences of opinion will be tolerated as long as you conduct yourself accordingly. If "the exercise of civility is beyond your ability" or you were never taught by your parents, feel free to take your toys and go home and vent your pent-up anger elsewhere.
