Advocates of Active SETI say it’s better to put our best foot forward first, before E.T. gets the wrong idea about us from shock jocks and reality TV. As in politics, define ourselves before someone else does it for us. Plus, they contend, they’d already know we’re here anyway.
Two new separate groups of scientists now want to send coded radio messages into the cosmos in hopes of deliberately attracting the attention of intelligent space aliens. Known as Active SETI (Active Search for Extraterrestrial Intelligence), it’s arguably no safer to entice unknown offworlders into our planetary living room than to invite total strangers in for coffee and crullers.
But even if they are totally unsavory, it’s highly likely that an interstellar civilization would already be picking up our electromagnetic leakage and therefore already know we’re here, Douglas Vakoch, President of the San Francisco-based non-profit METI (Messaging Extraterrestrial Intelligence) International, told me.
“It’s too late to conceal ourselves in the universe, so we should decide how we want to represent ourselves,” said Vakoch, an expert in interstellar message construction. “ Extraterrestrials may be waiting for a clear indication from us that we’re ready to start talking.”

A new study released by NASA on Tuesday shows that oceans on Europa, one of Jupiter’s 67 known moons, might have a lot in common with our own oceans, including a chemical balance capable of harboring life.
Scientists have been eyeing the mysterious water world as one of the most promising places to find alien life for a while now, and this study suggests they’re on the right track.
The moon, which is only a quarter the size of Earth, is covered in a thick shell of ice. But there is strong evidence that there could be a salty ocean deep beneath its surface.

Friends have been asking me to write something on space exploration and my campaign policy on it, so here it is just out on TechCrunch:
When people think about rocket ships and space exploration, they often imagine traveling across the Milky Way, landing on mysterious planets and even meeting alien life forms.
In reality, humans’ drive to get off Planet Earth has led to tremendous technological advances in our mundane daily lives — ones we use right here at home on terra firma.
I recently walked through Boston’s Logan International Airport; a NASA display reminded me that GPS navigation, anti-icing systems, memory foam and LED lights were all originally created for space travel. Other inventions NASA science has created include the pacemaker, scratch-resistant lenses and the solar panel.
WASHINGTON — Space is vast, but it may not be so lonely after all: A study finds the Milky Way is teeming with billions of planets that are about the size of Earth, orbit stars just like our sun, and exist in the Goldilocks zone — not too hot and not too cold for life.
Astronomers using NASA data have calculated for the first time that in our galaxy alone, there are at least 8.8 billion stars with Earth-size planets in the habitable temperature zone.
The study was published Monday in the journal Proceedings of the National Academy of Sciences.

Interesting approach to the topic.
Do aliens exist? Carlo Rovelli, a founder of loop quantum gravity theory and author of the best-selling book “Seven Brief Lessons on Physics,” says it’s an easy question.
“There is so much space up there that it is childish to think that in a peripheral corner of an ordinary galaxy there should be something uniquely special,” he writes. “Life on Earth gives only a small taste of what can happen in the universe.”
Humans do have a long history of thinking they are special, though we’re gradually learning otherwise.
One can hope.
Although it’s likely to be a hope in vain, I’m afraid.
That said, you never know.
NASA is poised to reveal Tuesday new details about the hunt for life – intelligent or otherwise — in the cosmos.
If aliens sent you an encrypted binary message, could you answer? René Heller, an astrophysicist at the Max Planck Institute for Solar System Research, wants to hear from you.
Last month, Heller posed a hypothetical question as part of the #SETIDecryptChallenge: “Suppose a telescope on Earth receives a series of pulses from a fixed, unresolved source beyond the solar system,” he wrote. “It turns out the pulses carry a message.”
The encrypted message is a vast sea of 0’s and 1’s. You can see it here, but here’s a GIF for your convenience.
