New imaging of Europa’s surface
Oh Jupiter, do you hold the secrets of the solar system?
Do the little green men reside there?
How do you know we are Martian?
Many people point to Jupiter’s moon Europa as being the logical place to find life other than us. The crust appears to be frozen water and a vast liquid ocean might be underneath. So vast it contains many times more water than earth!
Jupiter is also large enough to generate heat in it’s rotating moons (I don’t really understand how but I read that far!)
So with water and heat perhaps come life as small as microbes or as large as fish, say our smartest scientists and theorists.
Well according to Arthur C. Clarke, much larger than fish, perhaps tree-sized jellyfish! Way bigger than whales, perhaps bigger than any single item on earth, with consciousness we may or may not understand.
That’s cool stuff. Hope they like us.
Hope we don’t kill them.
I’ve recently favored a different moon of Jupiter for the perfect mothership parking lot – Io.
We really don’t know what’s behind the crust while it should contain all of the other advantages of Europa. Maybe it’s not fish underneath there, maybe it’s spaceship parking.
Io is perfectly designed for this task with it’s metallic crust that we can’t see or otherwise detect past. It basically has a shield for a crust. A shield that stops all of our current detection and scanning techniques.
Bonus the convenient naming Io to help keep it out of our conciousness. Computers have trouble indexing something named Io. Go ahead, have fun searching for Io info.
What’s inside Io?
Will there be life after passwords? We are currently drowning in them – some more than others. A fella like me might need to enter 50 different passwords of increasing complexity just to get by a week in 2014.
It’s a growing problem because hackers and their security breaches, accompanied by the illegal market for passwords farmed from cracking programs, has made it difficult to stay secure, even with such complex passwords. Putting spaces in them helps but it’s not really simplifying anything.
So what to do about it? Is there a world in which we can live with all the technology minus all the passwords? DARPA (the peeps who started the internet 40+ years ago) is working on it, and their studies are fascinating. Here’s some potential replacements for the password (aka “user authentication”):
- Your heartbeat vibrations, as recorded by your phone
- The way you respond to error and system messages (a personality test)
- How your hand shakes as you hold it. Grandpa method.
- How you write texts and emails, based on slang and favorite phrases.
- The “visual fingerprint”: both camera inputs and the screen activity on the phone. The phone needs to see daddy (or his pocket) to turn on!
- How you walk (your gate) as recorded by your phone over time. Walk to unlock?
Read about these programs here.
This is pretty amazing tech, with many of these methods already working on modern phones using no added hardware.
But the flip side as I see it at first blush: we are giving up our anonymity even more, giving that much more power to the machines. If my phone needed to know it was me to use it, no matter what, while that is secure it just isn’t practical. A spouse, business partner, tech support, small business, children and friends are all potential password sharing situations.
If we have to prove we are allowed into the machine beyond ways that we are able to share through human methods, then we have lost that much more control over the machine world.
But yay! The future sure will be fun! If my machine must know it’s me for security purposes, it will know it’s me for other less critical purposes.
Yes that’s right. Researchers have used some cool computer programming and video chip tricks to do what was previously impossible – to use video to record vibrations made by sound and then recreate the sound.
No sound recorded, just video of something like a paper bag or a pair of headphones. The camera chip manages to see tiny variations in the image which are calculated out as vibrations caused by a sound source. The computer can actually process the video frames in such a way as to reconstruct the original audio that caused the vibration!
Wow! That’s a whole new world right there. And it goes to show that sound is a physical vibration that affects all physical items in an intimate way.
There are some things stopping this from being totally magical at this early stage of research — the computer program takes hours to process the video, the video needs to be recorded at a high frame rate and the recreated sound is not nearly as high definition as the original. But it is sufficiently recognizable, enough so that they were able to Shazam the recreated audio with a match!
Just thinking of the good and bad uses for this and my mind boggles. Video investigations, surveillance, items that react to sound…
Wow. Mexican researchers have completed their models of earth’s ‘ejecta’ (this outstanding word is the stuff the earth would eject out of it’s gravity after getting hit). Turns out that not only would our moon and Mars be logical targets for the ejecta, but potentially life-bearing earth rocks would also hit Jupiter much more than suspected.
You’ve probably heard about Jupiter’s various moons (Io, Europa, Ganymede…) being a favorite choice of possible ET homes and this study lends possibility to that. Early earth could have been slammed hard enough to kill the dinosaurs and blast a few giant chunks towards Jupiter. We get our chocolate in their peanut butter and the rest is history.
If one of those planets has the ET race earthlings keeps drawing and seeing in their dreams I wonder if they are gonna like our probes heading their way?
