The nighttime sky looks deceptively tranquil. In reality it is alive with a variety of brief but violent outbursts popping on and off like July 4th fireworks. Stars explode in faraway galaxies and neutron stars hiccup in a burst of radiation as they devour companion stars. Mysterious blasts of gamma rays, possibly from collapsing black holes, zap earth from deep space. It’s a daunting task for astronomers |

Here is something to look for in March 2005:

Now, a space shot at some humor.....
Imagine if you will... the leader of the fifth invader force speaking to the commander in chief...
"They're made out of meat."
"Meat?"
"Meat. They're made out of meat."
"Meat?"
"There's no doubt about it. We picked several from different parts of the planet, took them aboard our recon vessels, probed them all the way through. They're completely meat."
"That's impossible. What about the radio signals? The messages to the stars."
"They use the radio waves to talk, but the signals don't come from them. The signals come from machines.""So who made the machines? That's who we want to contact."
"They made the machines. That's what I'm trying to tell you. Meat made the
machines.""That's ridiculous. How can meat make a machine? You're asking me to believe in sentient meat."
"I'm not asking you, I'm telling you. These creatures are the only sentient race in the sector and they're made out of meat."
"Maybe they're like the Orfolei. You know, a carbon-based intelligence that goes through a meat stage."
"Nope. They're born meat and they die meat. We studied them for several of their life spans, which didn't take too long. Do you have any idea the life span of meat?"
"Spare me. Okay, maybe they're only part meat. You know, like the Weddilei. A meat head with an electron plasma brain inside."
"Nope. We thought of that, since they do have meat heads like the Weddilei. But I told you, we probed them. They're meat all the way through."
"No brain?"
"Oh, there is a brain all right. It's just that the brain is made out of meat!"
"So... what does the thinking?"
"You're not understanding, are you? The brain does the thinking. The meat."
"Thinking meat! You're asking me to believe in thinking meat!"
"Yes, thinking meat! Conscious meat! Loving meat. Dreaming meat. The meat is the whole deal! Are you getting the picture?"
"Omigod. You're serious then. They're made out of meat."
"Finally, Yes. They are indeed made out meat. And they've been trying to get in touch with us for almost a hundred of their years."
"So what does the meat have in mind?"
"First it wants to talk to us. Then I imagine it wants to explore the universe, contact other sentients, swap ideas and information. The usual."
"We're supposed to talk to meat?"
"That's the idea. That's the message they're sending out by radio. 'Hello. Anyone out there? Anyone home?' That sort of thing."
"They actually do talk, then. They use words, ideas, concepts?"
"Oh, yes. Except they do it with meat."
"I thought you just told me they used radio."
"They do, but what do you think is on the radio? Meat sounds. You know how when you slap or flap meat it makes a noise? They talk by flapping their meat at each other. They can even sing by squirting air through their meat."
"Omigod. Singing meat. This is altogether too much. So what do you advise?"
"Officially or unofficially?"
"Both."
"Officially, we are required to contact, welcome, and log in any and all sentient races or multibeings in the quadrant, without prejudice, fear, or favour. Unofficially, I advise that we erase the records and forget the whole thing."
"I was hoping you would say that."
"It seems harsh, but there is a limit. Do we really want to make contact with meat?"
"I agree one hundred percent. What's there to say?" `Hello, meat. How's it going?' But will this work? How many planets are we dealing with here?"
"Just one. They can travel to other planets in special meat containers, but they can't live on them. And being meat, they only travel through C space. Which limits them to the speed of light and makes the possibility of their ever making contact pretty slim. Infinitesimal, in fact."
"So we just pretend there's no one home in the universe."
"That's it."
"Cruel. But you said it yourself, who wants to meet meat? And the ones who have been aboard our vessels, the ones you have probed? You're sure they won't remember?"
"They'll be considered crackpots if they do. We went into their heads and smoothed out their meat so that we're just a dream to them."
"A dream to meat! How strangely appropriate, that we should be meat's dream."
"And we can mark this sector unoccupied."
"Good. Agreed, officially and unofficially. Case closed. Any others? Anyone interesting on that side of the galaxy?"
"Yes, a rather shy but sweet hydrogen core cluster intelligence in a class nine star in G445 zone. Was in contact two galactic rotations ago, wants to be friendly again."
"They always come around."
"And why not? Imagine how unbearably, how unutterably cold the universe would be if one were all alone."

And, more or less in conclusion of this page....... because you've had it FAR too easy this day, here's Carl Sagan's question:
Is there intelligent life beyond the solar system?
Astrophysicist F. D. Drake attempted to illuminate the parameters and uncertainties involved, in what he called a "simple way of approaching the problem." The number N of extant technical civilizations in the galaxy can be expressed by the following equation (the so-called Green Bank formula):
N = R*fpneflfifcL
where R* is the average rate of star formation over the lifetime of the galaxy; fp is the fraction of stars with planetary systems; ne is the mean number of planets per star that are ecologically suitable for the origin and evolution of life; fl is the fraction of such planets on which life in fact arises; fi is the fraction of such planets on which intelligent life evolves; fc is the fraction of such planets on which a technical civilization develops; and L is the mean lifetime of a technical civilization. There's more (you await with bated breath) but you'll have to read Sagan's commentaries to get it.
Now, MY question is:
Is there a formula to determine the amount of intelligent life on THIS planet? No, I didn't ask whether there WAS, just the amount!
